The BM1 is the AMPS companion battery monitor. Suitable for monitoring up to 500A flow in/out of any particular point. This is a negative line shunt and comes with a round monitor and bluetooth communication.

The BM2 is the BM1's bigger brother - communicating more information to the user at any given time due to the larger display.

Bluetooth included, shunt specifics are the same as the BM1.

The PMP is a comprehensive power monitor, allowing you to monitor up to four channels at a time.

The PMP's shunts can be used on either Positive or Negative cable lines- which is rare on the market.
