About Wattrae

Lead-acid to lithium, engineered for industrial reality.

Wattrae Energy is a Chinese manufacturer focused on a single discipline: converting industrial equipment from lead-acid to LFP lithium. Our packs, BMS, chargers and battery boxes are designed together — not assembled from third-party parts — and shipped worldwide with full UN38.3 documentation.

Our story

Wattrae started by engineering retrofit packs for forklift fleets that could not afford a second shift lost to lead-acid charging. The first conversions taught us that customers do not want a battery — they want a working truck on Monday morning. Everything we ship is judged against that.

Today we build complete LFP kits for forklifts, golf carts, aerial work platforms, airport ground support equipment, cleaning machines and pallet trucks. Cells, BMS, charger profiles, harnesses, custom steel boxes and engineered ballast are all matched in-house, then certified for sea freight to operators in over 40 countries.

Why Wattrae

Conversion is a system, not a part

Every Wattrae shipment is a matched system. Six things make that possible.

  • In-house BMS

    Active-balancing BMS designed, programmed and tested by our own electronics team — with CAN/RS485 diagnostics.

  • Custom battery boxes

    Steel enclosures CAD-matched to OEM compartments, with engineered ballast where forklift stability requires it.

  • Fully matched kit

    Pack, BMS, charger profile, harness and connectors all tuned to each other before the kit leaves the factory.

  • UN38.3 & sea freight certified

    Every shipment ships with UN38.3, MSDS and sea-shipping appraisal — customs and forwarders accept first time.

  • Technical & install support

    Installation manuals, video walkthroughs and remote engineer support for the first conversion on every model.

  • Multi-year warranty

    Standard 5-year warranty on cells, BMS and electronics, backed by a worldwide RMA process.
