BATTERY PACK
(Lithium-ion)

IET’ s Lithium-ion Battery Module, is composed by 224 super high rate 18650 cylindrical battery cells, with a proprietary design and high efficient BMS (Battery Management System) developed by IET’s internal unit design, which guarantee the highest level of cells safety.

The high performing electrical parameters release super high power up to 3C (3x nominal capacity discharge) and the self-developed structure has high performance even under low temperature (-20°C).
This Battery Module has been designed for several application such as Recreational, Karting, Automotive, Ride Attractions/Parks, Material Handling, Industrial, etc.
