The 51.2V configuration exists because physics rewards precision. A true 16-cell series arrangement aligns precisely with LiFePO4 nominal voltage characteristics, placing the motor controller in its most efficient operating band throughout the entire discharge curve. The result is tangible: more usable kilometres extracted from every unit of stored energy compared to conventional 48V equivalents.

Uttam Electric’s 51.2V 105Ah battery pack brings this engineering advantage to the e-rickshaw segment without demanding a vehicle overhaul. At 50 kg housed within 400 x 280 x 290 mm, the form factor mirrors standard 48V battery compartments. Transitioning from 48V to 51.2V requires minimal vehicle-side adjustments, making it a practical upgrade path for existing fleets.

Prismatic LiFePO4 cells deliver 105 ampere-hours of deeply cyclable energy. Approximately 98 km of range per charge, within a 10 km margin, covers the operating envelope of most urban and peri-urban e-rickshaw corridors. Charging at 20A reaches completion in about 5 hours, fitting neatly into overnight downtime schedules.

The smart BMS applies five concurrent protection layers: over-voltage, under-voltage, overcharge, deep discharge, and temperature regulation. No single fault pathway goes unmonitored. Data flows outward through Bluetooth, RS485, CAN, and UART channels, offering fleet operators and OEMs the flexibility to integrate with whichever telematics platform they prefer.

IP69 sealing handles the worst that Indian climate and road conditions can deliver. A 36-month warranty covering replacement and repair stands behind every unit. Custom enclosure dimensions accommodate next-generation vehicle designs. Engineered in India for operators seeking measurable efficiency gains without operational disruption.
