• Built-in BMS (Battery Manage-ment System) managing charge, discharge and state of charge based on proprietary algorithm.

• Anodised aluminium casing to withstand shocks and vibrations.

• LED display for fuel gauge and battery status.

• Communication and remote control possible through the BPCI® (Battery Protection and Communication Interface) bus.

• Robust main connector and specific connector for charge. Energy recovery (regenerative charge) during use is possible depending on the battery status.

• Auto-sleep mode and on/off key to protect the battery when unused or short-circuited.

• Designed for ease of parallel assembly.

• State-of-health indicator.• Discharge current up to 40 A

continuous.• 2 years/500 cycles smart

warranty.

Benefits• Ready for intensive use.• Plug-and-play design.• Autonomy on demand thanks to

plug-and-play parallel assembly.• Robust and easy connecting.• Remote on/off control HMI

(Human Machine Interface) possible.

• Protection against common mishandling (high temperature, short-circuit…).

• Electrical deactivation in sleep mode.
