BYD Forklift DC-DC Converter 10739003-00 – Original OEM Electric Transformer

BYD Forklift DC-DC Converter 10739003-00 — Original OEM Electric Transformer

This is the original BYD DC-DC converter (part number 10739003-00) for BYD electric forklifts — not an aftermarket or universal replacement. Unlike generic converters that match only voltage range, the BYD OEM unit is calibrated specifically for BYD traction battery characteristics including the battery management system’s voltage curve, regenerative braking voltage spikes, and the specific current draw profile of BYD forklift auxiliary systems. Using a generic converter on a BYD forklift risks undervoltage shutdown during heavy lift operations, 12V rail instability that corrupts controller electronics, and overcurrent faults that disable the forklift mid-operation.

The 10739003-00 converter steps down the high-voltage traction battery to 12V/24V for lights, horn, instrumentation, and controller electronics. Manufactured in Fujian, China with 3-month warranty and online after-warranty support. EM customized services available for fleet-specific requirements. Supply capacity of 1000 pieces per month from Xiamen port. Weighs 2-3 kg in luxury specification size. Always disconnect the traction battery before installation — the input side is high-voltage DC.

Compatible with BYD electric forklifts using the 10739003-00 OEM specification. Not interchangeable with aftermarket converters or converters from other brands. Browse our DC converter selection for Hangcha and other brands.
