I've been putting together a 271ah (4s 12v) battery for the last few days and running into issues with my BMS limiting current when I put a load on it. I'm thinking about just dropping the BMS altogether. I just ordered an overkill BMS that is supposed to arrive on Thursday but we're going to leave in our camper on Friday so I'm cutting it pretty close.
I have a Victron smart solar MPPT controller and a Victron DC-DC Orion-TR charger and they should be enough protection from overcharging. Because we will be living in a truck camper for a month I will be able to monitor the battery voltage and SOC closely with this battery monitor which will allow me to set alarms for over/under voltage conditions. Plus I have this little balancer to rebalance the cells if needed and it's already wired up and working.
So should I just plan on not having a dedicated BMS and keep a close eye on it and trust my Victron chargers to not overcharge? Or should I punt and put those heavy AGMs back in?
