[EVDL List]

Hmm... your confidence in technology is impressive.
Individual PbA battery chargers have been around for a long time now and
many EV'ers have adopted their use in charging batteries in strings. Yet
how few cases have there been where you've heard someone say they have never
had a problem with at least one of these chargers over the life of their
batteries? Even suppliers with a great reputation for building quality
chargers sell duds. That alone should make one think twice about trusting
any particular BMS without reviewing its success rate.

physically incapable of doing the same?<<<


I would like to think that as the BMS improves it would get to the level of
excellence of any other product out there. I know I am working on a BMS that
if given enough engineering time should be next to perfect.
