Valence U1-12RT Lithium Battery
Anybody have any direct experience with these? I was recently given two Valence U-Charge U1-12RT 40AH battery modules that were salvaged out of some hospital med carts. I’m not sure how old t...

Yeah, just trying to get an idea of what kind of capacity they have with the two of them paralleled.
I don’t have a DC amp meter that can handle more than 10 amps, but if I can trust the numbers from the Kill A Watt meter, I think I was putting about a 12 amp DC load on it. It ran for about 5.5 hours. The battery voltage must’ve gotten down to 10 volts (under load) because the BMS shut it off.
This is before I unplugged the batteries from the inverter. (0.833 volts DC)
As soon as I unplugged the batteries, the voltage jumped up to 11.22 volts. I guess the BMS is working :B
I’ll cycle them a few times and see what their trend is.
