GOod but would maybe consider a JK or Overkill active BMS 

Fantastic piece of kit. Measures energy in and out of batteries perfectly. Predicts usage remaining.

Fantastic off-grid inverter. Connects via generator or large solar input. All in one and easy to connect. A little loud so make sure its in a well ventilated but acoustic insulated cupboard or electric outhouse.

Fantastic packaging and delivery. All cells were grade A and delivered over 280ah when tested.
