My 4x 230ah LTCP 12v LiTime batteries finally arrived here in Alaska.
I checked each of the batteries when I first unpackaged them and they were all roughly 13.1v. I connected them in series and connected them to my new EG4 3kw 48v all in one unit. Everything worked as expected. I connected the unit to shore power and put the batteries on a 20amp charge. LiTime recommended charge rate is 46amps. I put them on the lower rate as I need to upgrade some of the wiring size from shore power.
They charged fine for a number of hours (5 or so) until the EG4 stopped charging due to an over voltage condition. I checked each of the batteries while resting. 3 of them show 13.3v and the 4th battery is showing 18.0v.
thoughts?
Edit: when they were first charging the system voltage was in the high 53v range with constant current. Over the next several hours the voltage rose into the low 54v range as expected. Current was steady. My guess is the 1 battery had a sudden voltage spike which caused the EG4 charger to turn off.
