My charger is set to be the right voltage but the old cells being 22 in series string they need to equalized out at the top/end of the charge. this requires some battery baby sitting, if your cells are staying very well balanced then your voltage cut off method/gadjet may be good . your ebay gadget coud also be be good for those wanting to do a lower state of charge, like turn the voltage down 5 volts for a 10% lower top charge. I have 2 ev scooters with 22 and 24 lfp cells. wheres the voltage cut off gagaet on ebay?? _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
