Yerf said:The funny thing is the cells were balanced after the charger finished its charge cycle (it may have took 26 hours, life is a bit of a blur right now since we have a newborn So I believe the batteries were charged. weird thing is that the charger ran on bulk setting the whole way through. But I never saw the cells reach a higher voltage than 3.35vdc. When using the chargers lithium setting.
Yerf said:So basically I have to make sure they all reach 14.2vdc and then baby sit them until all cells are the same voltage?
Yerf said:I have to put it on normal charge + recondition mode to get it to go into long and slow absorption. But it's a bit scary because I fell asleep and woke up to a high battery Vdc. For some reason the battery charger was charging at 14.4vdc and then suddenly switched itself to 14.6vdc. Luckily I caught it just in time.
What I did was put the battery on charge at 2 amps on liion setting. Waited over 24 hours to finish and then charged it on normal + recondition setting. Then I started seeing the voltage climb to 3.6vdc per cell, it was scary because one was lagging behind at 3.49vdc. It took around 5 hours to get the other cell to 3.6vdc which then I had to turn off the charger manually.
I've only done that with one of the batteries so far. Should I do the rest in the same way? I've already charged all of them fully on the liion setting.
Yerf said:I will do that top charge in normal mode. Once all cells reach 3.6vdc I will consider them done and switch it off manually?
While the batteries were charging (the bank was at 56.8vdc absorption ) I noticed 2 of the batteries had a high cell voltage and one had a low cell voltage compared to the others.
The bank went below 50% at one point and I thought I'd try the generator to see how they charge. They were charging at 400 amps! So I shut it down. I'm thinking of setting it at 200 amps. What do you guys think?
