AEK-POW-BMSNOTX overview

Our offer for BMS evaluation boards also includes the
cells.
Like the AEK-POW-BMS63EN, this board is based on the L9963E.
This embedded L9963E device can act as a transceiver, directly communicating with an MCU via SPI.
The board is particularly fit for auxiliary battery systems to supply power for devices (such as audio system,
window cleaning
system, seat heating, light system, light signalization, climate control system) connected to your vehicle (even
when the engine
is not running), ensuring the main starting battery is reserved for engine cranking and vehicle electrical
requirements.
