I just bought 3 x 12.8v 160AH victron batterys, sold as 'good'.
Two are indeed fine, and I've connected them (separately) to a BMS 12/200 as they haven't been used for a while, to re-charge & re-balance.
The 3rd however is reading 9.8v, and the BMS won't allow it to charge, presumably a low voltage protect. Is it dead? or could I try applying a normal charger, to try & boost the voltage above the low voltage limit?I'm guessing its dead, but I told the seller I'd see if anything could be done.
Also, I can't seem to find any info specific to this battery on the Victron website, just the smart batteries, which look a little different, so could someone tell me more about this battery? ie, is it a 'Smart Battery'? I guess its an older, non-smart one, but I'm not sure.
Also, does it have a BMS built in? so I can just charge it with any charger? or do I always have to use the BMS 12/200?
One more thing :) does that mean it doesn't have the bluetooth monitoring?
If thats the case, is a BMV700 the best kind of monitoring system?
Basically, I have one working system in a camper, with bms12/200, which is great, but doesn't have any monitoring yet, and I'm looking to build a second, larger one, with solar, and monitoring for both.
Thanks in advance.
