I blew up a 100A Daly bms by over drawing it - we're talking a 12V circuit here, so bought a 250A unit. During operation from my CALB pack, the 100 did a fine job of what was expected of it, then I plugged in my fridge. I have a 1200VA Victron inverter that powers my experimental system before I go 48V and build a proper system. The peak of the fridge compressor blew the 100A daly, so I upgraded to a 250A model.
3 months later while I was at the pub hanging out with mates I get a call from my friend who is back as my place. "Hey mate, something just went bang and the power went off. The TV and the computer just turned off" (I have a server, a fairly efficient one).
When I got home I could smell that burned electronics smell. I bypassed the battery so my mate could continue to watch the show he was watching from my server.
I sat down beside him and got on my phone, and went to batrium.com and ordered these toys.
Now bear in min I plan on upgrading to a 48V system, however I have been experimenting with a 12V system, comprising 180Ah CALBs, Victron Smart Shunt, Victron 12/1200VA inverter and Victron 150/35 fed by 440W of solar on the roof.
All this gear has been kept in check by a raspi running venusos, and a Daly BMS.
Both BMS's died, blowing out their output fets, not the charging ones.
So. Heres what I purchased:
Batrium CORE watchmon
Batrium Expander Module for Watchmon
4 x LongMons
Batrium ISOmon
And a few other bits and bobs.
I got the expansion module so that if my batteries run low, the relays can turn stuff off like the inverter, and chuck on some fans during charging to keep the 150/35 cool. Once a month it can also kick on my "Flying Capacitors" brand balancer (really when I saw the name of this thing I thought, do I need to attach this to my battery via long leads and swing it around my head to make the capacitors fly and do what they need to do? haha).
When I Go to 48V I'll just need to buy 12 more long mons and reprogram the system.
Batrium aint cheap. but considering I have spen a fuck tonne on BMS's including cheap china, DALY and waiting ages for the one in the blue box whos name I forget only to find its the wrong type.
I plan on doing some you tube videos like Off Grid Garage and The Digital Mermaid (hi Andy and Madi!) when my Batrium arrives
