Phew..
The Chopper saga is a long one..

Way back then, it was going to be a lead sled..
But, that never materialized, it ended up on 12ah prismatic lifepo4, those only lasted a season of almost no usage..

then tore it down and built a 10ah PSI cell pack:

The whole BMS thing turned into a huge Fail, so stripped it off and have been running it straight up.
Currently 24 cell 10ah PSI lifepo4, this pack has been accidentally drained down to 0v by the DC/DC converter , and a 2nd time by the Soneil chargers ( plugged to pack but not to AC ) .. and recovered it both times.. has 1 less than ideal cell but the pack still delivered 8ah last year.
