I have a SE-1072 that I have been using to charge my 8 batteries. I have 2 banks of 4 and I set it to 48 volts and wire both banks parallel with the charger. I usually keep an eye on it for when the needle gets to 0.
I have 2 questions:
1. If one of the batteries is 90 percent charged and I leave the charger charging it with the rest of the series, will that kill my battery? or will it load balance over to the rest?
2. If my batteries are at 80% and I leave the charger on over night and lets say it gets to 0 at 2 am and I don't check it until 6, will I kill my batteries because they where full for the last 4 hours? or does it trickle charge them?
