Could a circuit like this work? Using a Switch Mode DCDC step down converter (48-24v) to 12v. Output from the transformer charge the whole bank, or individual sell groups. Effectively using the load as balancing resistors. FETS on the output of the transformer directly power the load or charge week groups. Low speed switching to maintain battery voltage????
Also laser cut ends for the hyperbaric test chamber arrived- I will try to stick them to the cylinder
this week. And do a few more videos squashing stuff.
Battery testing we have collected and tested 60+ cells. About 2/3 are ok and will store a reasonable amount of power. So we still need a few more to make the 45 cell pack.
