Just fiigured i would get a little more out of the pack, i got the pack for 20 bucks, so if i can get a few months out of it ill be happy!

any opinions for a good equalizer, dont need one to discharge, my charger does that for me

i have a five minute delay between cycles
You should have your delta peak between 2mv and 5mv. The cells should not get much hotter then 120 at the time of peak. If they are getting much hotter then that you can risk damaging the cells.

all you have to do to stop the venting is buying an equalizer

they vent cuz wen u charge them and discharge not all the cells have equal energy left in them
