Light enough to cradle in a single palm. Purposeful enough to illuminate an entire night. The Uttam Electric 12.8V 12Ah Soft Battery Pack is the smallest unit in the catalogue, yet its contribution to rural electrification and residential backup is outsized. Across India, solar street lights and compact UPS systems depend on precisely this form factor: minimal mass, maximal reliability.

At just 1.2 kg within a 135 x 70 x 75 mm soft pack enclosure, this battery vanishes inside solar light housings and mini inverter chassis. The pouch cell format uses flexible LFP cells rated at 6000 mAh, conforming to spatial constraints where rigid prismatic or cylindrical alternatives simply cannot fit. Five protection layers—over-voltage, under-voltage, overcharge, deep discharge, and temperature—operate continuously within the integrated BMS.

IP65 ingress protection handles rain splash, windblown dust, and the humidity gradients common in outdoor and semi-outdoor mounting positions. The 24 to 36 month warranty with repair coverage aligns with typical solar lighting infrastructure replacement cycles. Custom dimensions are available for manufacturers integrating this pack into proprietary enclosures. Manufactured in India for the installations that bring light where darkness once governed.
