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

Overview

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, 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 article-level and conversion e-bikes in India. It supports:

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:

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.

Frequently Asked Questions (FAQ)

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 skips the equalization stage that lead-acid batteries need to stay healthy.

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

Which battery types does the Systellar UBC support?

The UBC supports five battery configurations from a single device:

  • LiFePO4 12.8V — end-of-charge 14.6V. Solar street lights, off-grid solar, e-bikes, inverter upgrades.
  • Li-ion 11.1V (3-cell) — end-of-charge 12.6V. Budget e-bikes, e-cycles, solar fans, home lighting.
  • Li-ion 14.8V (4-cell) — end-of-charge 16.8V. Higher-capacity e-bikes, cargo cycles, power backup.
  • Lead Acid Flat Plate 12V — end-of-charge 14.4V. Two-wheelers, small solar UPS, inverters.
  • Lead Acid Tubular / Gel 12V — end-of-charge 14.8V. C10 tubular batteries in home inverter systems.

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

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

A standard lead-acid charger will damage a LiFePO4 battery for three reasons. First, its equalization mode periodically applies a high voltage (15V+) to balance cells — LiFePO4 cells cannot tolerate this and suffer irreversible damage.

Second, the lead-acid float voltage (13.3–13.8V) is too low a trigger for LiFePO4: the charger reads a healthy, partially discharged pack as nearly empty and begins overcharging it. Third, the end-of-charge voltage differs — LiFePO4 needs exactly 14.6V, while lead-acid chargers top out at 14.4V (flat plate) or 14.8V (tubular).

The UBC eliminates this by giving each battery type its own precisely controlled profile, with no risk of cross-chemistry damage.

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

Yes — the UBC is one of the most capable 12V e-bike battery chargers available in India. Most Indian e-bikes and e-cycles use a LiFePO4 12.8V pack or a Li-ion 3S (11.1V) or 4S (14.8V) pack, and the UBC supports all three.

The UBC-15A is particularly well suited to e-bikes: at 15A it charges a 20Ah LiFePO4 pack in about 1.5 hours, and the adjustable current limit lets you dial down to a gentler C/5 or C/10 rate to extend the life of an older pack. For e-scooter owners whose OEM charger has failed, it is a reliable Made-in-India replacement for both lithium and lead-acid packs.

Is this charger suitable for charging solar system batteries?

Yes. Solar owners and installers use the UBC as a standalone AC-mains charger for solar batteries. During extended cloudy periods, monsoon weeks or maintenance shutdowns, it recharges your battery bank directly from a 230V supply — without routing through the inverter or the solar charge controller.

It supports all chemistries used in Indian solar installations: LiFePO4 (preferred for modern off-grid systems), Lead Acid Flat Plate, and Tubular/Gel. Solar street-light contractors also use the UBC-5A as a portable bench charger for individual 12V modules.

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

Both support all five battery types. The difference is charging speed and current control. UBC-5A — max 5A; compact, ideal for smaller packs (up to ~20–30Ah), portable maintenance charging and solar street-light batteries. UBC-15A — max 15A, adjustable; faster for larger packs (20–100Ah).

The adjustable current matters for Lead Acid tubular batteries, typically rated at C/10 — a 100Ah tubular should be charged at no more than 10A, which the UBC-15A lets you set precisely. If unsure, the UBC-15A is the more versatile choice: it can charge at 5A or lower, but the UBC-5A cannot exceed 5A.

Is the charging fast and safe?

Yes. The microprocessor-controlled charging circuit delivers accurate constant-current / constant-voltage (CC/CV) charging tuned to the selected chemistry, for fast charging without overcharging or damaging the cells.
