Lithium packs built for the easybike working day
Bangladesh runs on three-wheelers — passenger autos, easybikes and cargo trikes. Our 51.2 V and 64 V LiFePO4 packs replace lead-acid directly, charge in a single working break, and survive monsoon roads and 40 °C afternoons. Grade A cells, IP67 sealing and a smart BMS you can read from your phone.

Four pack sizes for every three-wheeler class
Sizes below are the standard configurations we hold for Bangladesh. Charging times are measured from 20% to 100% state of charge with the supplied charger.

Why it lasts
What the pack is built out of
Cheap packs fail in the first monsoon. The difference is cell grade, how the pack is braced against vibration, and whether the BMS is actually balancing cells.
- Brand-new Grade A LiFePO4 cells — lasts 3–5 times longer than lead-acid
- Smart BMS guarding over-charge, over-discharge, over-temperature, over-current and short circuit
- IP67 waterproof construction — built for flooded streets and daily washing
- Reinforced anti-vibration structure for rough and unpaved roads
- High discharge rate with strong current output for loaded starts and climbs
- Rated for reliable operation up to 65 °C ambient
- Maintenance-free: no watering, no terminal cleaning
- No series wiring needed — one pack replaces the lead-acid bank
- Check battery status directly from a mobile app over Bluetooth
- Original charger included with every pack
Reference vehicles these packs are specified against
Our three-wheeler line is developed alongside RAP SEV electric three-wheelers, which run LiFePO4 packs in exactly these voltage classes.
