Hi all - I'm trying to decide on a BMS for my sprinter van battery system.
I'm looking at the REC ACTIVE BMS and the Orion Jr.
I like that the REC is already set up for 4S, and seems like it has the ability to work with the WS500 regulator I'm using, as well as Victron equipment.
But the Orion seems like it is better engineered with better documentation. The big con with the Orion, of course, is that you're limited to 150mA of passive balancing current. They claim that this isn't a big deal, but I do wonder about it. I will have 4 very high capacity cells in series; the cells are matched, but they still will need to be kept in balance, and I worry that 150mA just isn't enough to cut it for 1120Ah.
The big feature that I'd like is the ability to tell the WS500 and the Victron Multiplus II and the solar panel controller to stop charging, without needing to close a contactor to accomplish it. It seems like I should be able to do this with both systems.
Would love to hear from anyone who has experience with either BMS, and what they like and don't like about it.
