I just picked up 16 Valance batteries from a battery recycler for free. 3 had green flashing lights, 4 with battery low red lights and the rest had no indication at all.
was able to restore the 4 low battery to complete charge as well as 4 of the other non charged units back to full state.
still working on the rest.
also got one 24 volt and a couple of other similar onesView attachment 8415View attachment 8416View attachment 8417
They do not have any built in protection; there is a board on them that can communicate data(cell voltage, temps, current draw, SOC, etc) and do balancing, but an external module(like the VC1, or one of several open source options) with some sort of disconnect is required to protect them.does the Valence u27-12xp have a built in low voltage cut off and battery balancer? or do i need to get one. i have three of U27-12xp hooked up in series for my 36 volt trolling motor max load is 52 amps. I'm looking for a lot voltage cut off and. I have that thunderstuck VC1 BMS being shipped to my house.
If you ordered the VC1, why wouldn’t you use the outputs from it to control a disconnect relay?Question here to ask about low voltage disconnect on my set up advise me if I’m right or wrong. I have three valence batteries which I purchased to use for my trolling motor on my fishing boat. The trolling motor is a 36 volt with 52 amp max draw (open throttle). therefore I will hook the batteries in series. Now for the low disconnect do I need to fine only one that is 36 volt 60 amp? All I’m finding common volts 12,24 and 48. I have found a few 36 volts but it’s 30 amp. I wonder if I can get buy with a three 12 volts and hook each one directly to each 12 volt battery will that work. I think it will. But running 36 volts and one disconnect turns off then I’m feeding my 36 volt trolling motor only 24 volts of power.
