The kit consists of two used Tesla model S battery;s module 48V – 5.3 kWh + Mini BMS unit + replacement Tesla PCB to use as a 48V – 10.6 kWh battery pack with a maximum power of 45A.

With this kit, it is possible to use a Tesla battery module in a simple and safe way. The replacement Tesla circuit board makes it possible to easily connect the original tesla cabling to the mini BMS. Ideal for energy storage with a maximum power of 45 amp or 1800 watts continuous (max 3.5 kW peak – 5 seconds)

The kit includes a connection diagram and pre-installation of the mini BMS with the correct parameters.
