The maximum on the 12.8V platform. Fifty-four ampere-hours represents the highest energy density Uttam Electric achieves in the low-voltage soft pack format. This pack targets premium street solar lighting deployments where multi-night battery autonomy is a contractual requirement and high-capacity inverter backup installations where extended outage coverage is essential.

The 295 x 135 x 75 mm enclosure at 5.2 kg is the longest in the 12.8V series, yet the 75 mm profile height remains constant. This dimensional consistency means all eight 12.8V variants share identical mounting depth requirements. Equipment designers can specify any capacity from 12Ah to 54Ah without redesigning the battery compartment.

Five BMS protection layers address over-voltage, under-voltage, overcharge, deep discharge, and temperature across every cell group. IP65 environmental protection is built in. The 24 to 36 month warranty with repair coverage provides operational assurance. Custom dimensions serve specialised OEM needs. The pinnacle of the 12.8V soft pack range. Proudly produced in India.
