I choose Batrium Watchmon4+expansion board for the following reasons:
1. Able to communicate on CAN-Bus with my Victron CCGX
2. Making changes to the bms was easy and understandable. (Setting voltages, setting critical aspects, etc.)
3. It used a contractor so I could use my lithium RV battery to “boost” my chassis battery to emergency start my diesel RV. Needed a very high current- (estimated 500 to 1000 amps at 12v).
4. Wanted battery heating, cooling options with simple relays that I can understand.
5. I wanted controls to shut down battery gracefully and predictable when going into critical state (low voltage)
6. I like information- wanted to easily see status of battery.
Those are the reasons I choose Batrium. It seemed to completely fit my needs/wants/desires for a bms. They shipped very fast - about a week. (Batteries unfortunately don’t ship in a week - mine are in a container somewhere in China). (I haven’t installed it yet - that’s project is early spring).
For the contractor I choose Kilovac EV200AAANA - there is also others.
