The absolute pinnacle. The 72V 50Ah battery pack is Uttam Electric’s most powerful, most ambitious, and most technically advanced product across the entire catalogue. Fifty ampere-hours at seventy-two volts. Maximum voltage multiplied by maximum capacity. Every specification pushed to its uppermost limit.

Each 4500 mAh NMC cell is drawn from the top percentile of production output. Capacity matching, internal resistance sorting, and self-discharge rate verification reach the tightest tolerances achievable. At 26 kg within a 290 x 270 x 190 mm enclosure, this is the largest pack Uttam Electric manufactures. It targets vehicles where range is the defining specification: intercity-capable e-scooties, fleet vehicles covering triple-digit daily kilometres, and commercial platforms where a single charge must sustain an entire working shift.

The BMS represents the pinnacle of Uttam Electric’s battery management engineering. Multi-tier fault protection, predictive health monitoring, precision cell balancing, and adaptive charge profiling operate in concert. Five protection layers—over-voltage, under-voltage, overcharge, deep discharge, temperature—function as an integrated shield rather than independent circuits. Charging at 10A finishes in approximately 5 hours. IP69 certification and fire-retardant, water-resistant construction are absolute requirements at this level.

A 36-month warranty accompanies every unit. Custom dimensions serve bespoke OEM architectures. This product defines what Indian battery manufacturing can achieve at its best. Uttam Electric. Powering India’s future.
