Multiply 51.2 volts by 200 ampere-hours and the arithmetic reveals over ten kilowatt-hours of stored energy in a single enclosure. A figure that would have seemed implausible for the e-rickshaw segment just a few years ago now sits ready to install, ship, and deploy. The 51.2V 200Ah pack is the crown of Uttam Electric’s efficiency-optimised lineup.

Each LiFePO4 prismatic cell in this pack represents the largest format available in the Uttam Electric catalogue. Minimal internal interconnections mean reduced resistive losses and fewer potential failure points. The pack architecture is deliberately simple: fewer joints, fewer welds, fewer places where resistance can build and heat can accumulate. Simplicity at this scale is an engineering achievement, not an omission.

At 80 kg within a 500 x 360 x 270 mm housing, this unit demands a vehicle chassis purpose-built for its mass. The reward is extraordinary: approximately 190 km of range per charge with a 10 km tolerance window. Morning-to-evening operations become single-charge affairs. Intercity shuttle services, industrial campus loops, and high-frequency arterial routes all fall within its operational reach. Charging at 40A completes in about 5 hours.

The smart BMS orchestrates charge balancing across every cell, ensuring uniform ageing and preventing individual cell stress. Over-voltage, under-voltage, overcharge, deep discharge, and temperature protections run simultaneously without priority conflicts. Four communication protocols—Bluetooth, RS485, CAN, UART—deliver granular diagnostics to any connected monitoring system.

IP69 certification confirms resilience against pressurised water and thermal shock. The 36-month warranty offers replacement or repair at the manufacturer’s discretion. Custom dimensions are available for OEM vehicle programmes targeting the next generation of heavy-duty electric three-wheelers. Assembled in India for routes that run from first light to last.
