Build

Every pack is built in Gurugram from matched, capacity-tested cells with spot-welded nickel busbars, silicone main leads and a heat-shrink wrap, then load-tested before dispatch. Packs are assembled after payment and dispatch within 3–4 business days. Need a different connector, wire length or layout? Ask us on WhatsApp before ordering.
