Universal Battery Charger — India’s Only 12V Charger for LiFePO4, Li-ion & Lead Acid

Systellar Innovations, only manufacturer in India offering a universal charger for all three chemistry,  brings you the Universal Battery Charger (UBC). A groundbreaking, versatile charging solution designed to meet all your battery charging needs, no matter the type! As the only manufacturer in India offering a universal battery charger that can charge Lithium Ferro Phosphate (LiFePO4), Lithium-ion (Li-ion), and Lead Acid (Gel & FLA) batteries, we’re revolutionizing how you power up your devices. Whether it’s for your electric bike, solar-powered appliances, car batteries, or 2-wheelers, the Universal Battery Charger guarantees fast, reliable, and accurate charging.

The Only Universal Battery Charger in India That Charges All Three Battery Chemistries

Most battery chargers in India are built for one battery type only. Use a standard lead acid charger on a LiFePO4 battery and you risk permanently damaging the cells — because LiFePO4 requires a higher end-of-charge voltage and a strict CC/CV (constant current / constant voltage) algorithm that most lead acid chargers simply don’t deliver. Use a lithium charger on a lead acid battery and you skip the equalization stage that keeps tubular and flat plate batteries healthy.

Systellar’s Universal Battery Charger (UBC) solves this problem completely. As the only manufacturer in India to offer a single charger that correctly charges LiFePO4, Lithium-ion, and Lead Acid batteries from one device, the UBC eliminates the need to own multiple chargers for different battery types. Select your battery chemistry on the front-panel switch, connect, and the microprocessor-controlled charging circuit delivers the exact voltage profile that battery requires — automatically.

Available in two models: UBC-5A (up to 5A charging current) and UBC-15A (adjustable up to 15A). Both are compact, high-frequency designs made in Meerut, Uttar Pradesh.

Application 1 — Electric Bike & E-Scooter

Electric Bike Battery Charger — LiFePO4 & Li-ion, Made in India

India’s electric two-wheeler market is growing at over 40% annually. Ola S1, Ather 450, Ampere Magnus, Hero Electric, Okinawa, and dozens of other e-bikes and e-scooters all use either Lithium-ion or LiFePO4 battery packs — and almost every one ships with a proprietary charger that stops working the moment it fails. Replacement chargers are either imported, expensive, or incompatible.

The Systellar UBC is the ideal electric bike battery charger for 12V battery packs commonly used in entry-level and conversion e-bikes in India. It supports:

• LiFePO4 12.8V packs (end-of-charge voltage 14.6V) — the safest and longest-lasting battery chemistry for Indian two-wheelers
• Li-ion 11.1V packs (3S, end-of-charge voltage 12.6V) — standard in budget electric scooters and e-cycles
• Li-ion 14.8V packs (4S, end-of-charge voltage 16.8V) — used in higher-capacity e-bikes and cargo cycles

The UBC-15A model is particularly suited for e-bike battery charging — at 15A, it can charge a 20Ah LiFePO4 pack (a common e-bike capacity) in approximately 1.5 hours, minimising downtime between rides. The adjustable current limit on the 15A model also lets you set a gentler C/5 or C/10 charge rate for older packs where battery health is a concern.

Who needs this: E-bike conversion enthusiasts building their own lithium packs, electric scooter owners whose OEM charger has failed, EV kit installers supplying 12V lithium packs to customers, and fleet operators running multiple e-bikes who need one charger compatible with mixed battery stock.

Application 2 — Solar System Maintenance Charging

Solar Battery Charger for Off-Grid & Backup Systems — LiFePO4, Gel & Tubular

Every off-grid solar power system eventually needs its battery bank recharged from mains power — during a cloudy week, a long monsoon, or a system shutdown for maintenance. In these situations, most solar system owners are stuck: their MPPT charge controller only charges from solar panels, and a standard inverter charger may not support the lithium battery bank they’ve installed.

The Systellar UBC is a purpose-built solar system battery charger that works directly from AC mains (230V Indian supply) to charge the same batteries your solar system uses — without going through the inverter or the charge controller. It supports every battery chemistry used in Indian solar installations:

• LiFePO4 12.8V — the battery chemistry of choice for modern off-grid solar systems, solar street lights, and solar fans due to its 2,000+ cycle life and thermal stability in Indian heat
• Lead Acid Flat Plate 12V (end-of-charge 14.4V) — standard in budget off-grid home systems and small solar UPS setups
• Lead Acid Tubular / Gel 12V (end-of-charge 14.8V) — used in C10 tubular batteries found in most residential inverter backup systems in North India

For solar street light maintainers, the UBC-5A is a compact and portable option for topping up individual 12V battery modules removed from pole-mounted luminaries for bench charging. For home solar backup systems with 100Ah–150Ah tubular batteries, the UBC-15A’s adjustable current limiter allows you to set charging current within the C/10 rating typically specified by tubular battery manufacturers.

Who needs this: Solar system integrators and maintenance engineers servicing off-grid installations, homeowners with solar backup systems who need a standalone charger during low-solar periods, solar street light maintenance contractors, and anyone commissioning a new lithium solar battery bank who needs to pre-charge cells before first use.

Application 3 — Car & 2-Wheeler Battery Charging

Car Battery Charger India — 12V Lead Acid, Gel & LiFePO4 Automotive Batteries

A dead car battery is one of the most common vehicle breakdowns in India — especially after the monsoon or a long vehicle stand-still. Most car battery chargers available in India are basic trickle chargers that overcharge lead acid batteries if left connected, or cheap imports with no protection against reverse polarity or short-circuit.

The Systellar UBC is a smart car battery charger that brings microprocessor-controlled, multi-stage charging to Indian automotive and two-wheeler batteries. Unlike a simple trickle charger, the UBC delivers a proper charging sequence:

• Bulk charge phase — maximum current delivery to charge the battery as quickly as safely possible
• Absorption phase — gradually reduces current as voltage reaches the set point, preventing overcharge
• Float / maintenance phase — holds the battery at optimal storage voltage without boiling off electrolyte or stressing cells

This matters because modern car batteries — especially the Flat Plate (standard) and VRLA (Valve Regulated) types common in Indian cars — are damaged by sustained overcharging. The UBC cuts off automatically when the battery is full.

For the growing number of Indian cars and two-wheelers now fitted with LiFePO4 starter batteries (drop-in replacements for lead acid units — lighter, with more cold cranking amps), the UBC’s LiFePO4 mode delivers the correct 14.6V end-of-charge voltage that a lead acid charger cannot safely reach.

The UBC also works for 12V two-wheeler and bike batteries (motorcycles, scooters, mopeds) — particularly useful for bikes kept in storage, where self-discharge over weeks can leave the battery too flat to start.

Who needs this: Car owners and garage mechanics who want a reliable Indian-made smart charger, two-wheeler owners maintaining their bike battery during storage, auto electricians and service centres handling mixed battery stock across multiple vehicle types, and fleet managers maintaining vehicles fitted with both lithium and lead acid batteries.

Frequently Asked Questions — Systellar Universal Battery Charger

Q1. What is a universal battery charger and why do I need one?

A standard battery charger is built for one chemistry only — a lead acid charger cannot safely charge a LiFePO4 battery, and a lithium charger will skip the equalization stage that lead acid batteries need to stay healthy. If you own an electric bike, a solar power backup system, and a car — you technically need three different chargers.

The Systellar Universal Battery Charger (UBC) replaces all three. It is a microprocessor-controlled, 5-in-1 charger that detects your selected battery type and automatically delivers the correct charging algorithm — CC/CV for lithium chemistries, multi-stage for lead acid — from a single compact device. One charger. Every 12V battery you own.

Q2. Which battery types does the Systellar UBC support?

The Systellar UBC supports five battery configurations from a single device:

• LiFePO4 12.8V (Lithium Iron Phosphate) — end-of-charge voltage 14.6V. Used in solar street lights, off-grid solar systems, electric bikes, and modern inverter battery upgrades.
• Li-ion 11.1V (3-cell pack) — end-of-charge voltage 12.6V. Common in budget e-bikes, e-cycles, solar fans, and home lighting systems.
• Li-ion 14.8V (4-cell pack) — end-of-charge voltage 16.8V. Used in higher-capacity e-bikes, cargo cycles, and power backup equipment.
• Lead Acid Flat Plate 12V — end-of-charge voltage 14.4V. Standard in cars, two-wheelers, small solar UPS setups, and inverter systems.
• Lead Acid Tubular / Gel 12V — end-of-charge voltage 14.8V. Used in C10 tubular batteries found in most home inverter backup systems across North India.

Select the battery type using the front-panel switch, connect the clamps, and the UBC delivers the correct profile automatically.

Q3. Can I use this charger for my electric bike or e-scooter battery?

Yes — the Systellar UBC is one of the most capable electric bike battery chargers available in India for 12V packs. Most Indian e-bikes and e-cycles in the entry-level and conversion segment use either a LiFePO4 12.8V pack or a Li-ion 3S (11.1V) or 4S (14.8V) pack. The UBC supports all three.

The UBC-15A model is particularly well suited for e-bike charging. At 15A, it charges a 20Ah LiFePO4 pack — a common capacity in Indian conversion e-bikes — in approximately 1.5 hours. The adjustable current limit also lets you dial down to a gentler C/5 or C/10 rate if you want to extend the life of an older pack.

For e-scooter owners whose original OEM charger has failed or become unavailable, the UBC is a reliable Made-in-India replacement that works correctly with both lithium and lead acid packs — without the risk of overcharging or cell damage from an incompatible charger.

Q4. Is this charger suitable for charging solar system batteries?

Yes. The Systellar UBC is widely used by solar system owners and installers as a standalone AC mains charger for solar batteries. During extended cloudy periods, monsoon weeks, or system shutdowns for maintenance, the UBC lets you recharge your battery bank directly from a 230V Indian power supply — without routing through the inverter or the solar charge controller.

It supports all battery chemistries used in Indian solar installations: LiFePO4 (the preferred chemistry for modern off-grid systems due to 2,000+ cycle life), Lead Acid Flat Plate, and Tubular/Gel type batteries commonly used in residential inverter-solar setups.

Solar street light maintenance contractors also use the UBC-5A as a portable bench charger for individual 12V battery modules removed from pole-mounted luminaries for inspection or top-up charging.

Q5. Can the Systellar UBC charge my car battery or two-wheeler battery?

Yes. For car battery charging, the UBC delivers a proper multi-stage charge sequence — bulk charge, absorption phase, and float maintenance — that protects Lead Acid flat plate and VRLA/gel batteries from overcharging. Unlike a basic trickle charger that keeps pushing current even after the battery is full, the UBC’s microprocessor cuts off automatically when the battery reaches its target voltage.

This matters especially for modern Indian car batteries and two-wheeler batteries (motorcycles, scooters, mopeds) kept in storage, where unregulated trickle charging over weeks can boil off electrolyte and shorten battery life significantly.

For vehicles now fitted with LiFePO4 drop-in starter batteries — lighter lithium replacements for standard lead acid units, increasingly used in premium Indian motorcycles and retrofitted cars — the UBC’s LiFePO4 mode delivers the correct 14.6V end-of-charge voltage that a lead acid charger cannot safely reach.

Q6. What is the difference between the UBC-5A and UBC-15A models?

Both models support all five battery types — LiFePO4, Li-ion (3S and 4S), Lead Acid Flat Plate, and Tubular/Gel. The difference is charging speed and current control:

UBC-5A — Maximum 5A charging current. Compact and lightweight, ideal for smaller battery packs (up to around 20–30Ah), portable maintenance charging, solar street light batteries, and situations where a slow overnight charge is acceptable.

UBC-15A — Maximum 15A charging current, adjustable. Faster charging for larger packs (20Ah–100Ah range). The adjustable current feature is important for Lead Acid tubular batteries, which are typically rated at C/10 — meaning they should not be charged above one-tenth of their Ah capacity. A 100Ah tubular battery, for example, should be charged at no more than 10A; the UBC-15A lets you set this precisely. Also the better choice for e-bike and solar battery charging where minimising downtime matters.

If you are unsure which model to buy, the UBC-15A is the more versatile choice — it can always be set to charge at 5A or lower, but the UBC-5A cannot exceed its 5A limit.

Q7. Why can’t I just use a regular lead acid charger on my LiFePO4 battery?

This is the most important question for anyone considering a battery upgrade in India. A standard lead acid charger will damage a LiFePO4 battery for three specific reasons:

First, lead acid chargers have an equalization mode that periodically applies a high voltage (15V+) to balance cells. LiFePO4 cells cannot tolerate this — it causes irreversible cell damage.

Second, the float voltage on a lead acid charger (typically 13.3–13.8V) acts as a trigger: once the battery drops below a certain voltage, the charger starts a new bulk charge cycle. For LiFePO4 batteries, this trigger voltage is too low — the charger interprets a healthy, partially discharged LiFePO4 battery as nearly empty and begins overcharging it.

Third, the end-of-charge voltage is different. LiFePO4 requires exactly 14.6V for a 12.8V pack. Most lead acid chargers top out at 14.4V (flat plate) or 14.8V (tubular). Neither is correct for LiFePO4, and the narrow 0.2V difference has an outsized effect on whether cells are fully charged or gently overcharged over hundreds of cycles.

The Systellar UBC eliminates this problem entirely — each battery type gets its own precisely controlled charging profile with no risk of cross-chemistry damage.
