Thanks MLK, I was hoping you would take a look
It's just an experiment really, I need to get multiple batteries for various 360's
I've been reading about DIY circuit boards and various etch solutions. I don't have a lazer printer or access to one (plus, haven't got a circuit I need a board for so thought I would experiment with a Sharpie and stuff I already mentioned at beginning)
Thought I'd try a 'proof of concept' as I'm pretty much only using the CB to check other peoples carbs at present so a new battery may die before I get a chance to use it
I first found out about them when they were being used for regenerative braking on electric buses in Europe, battery couldn't cope with a sudden 'XXX' amp input so 'ultra capacitors' were developed to take the charge then distribute it slowly into battery. Made any braking or even slowing down much more efficient as there was always some charge being applied. Turns out they could hold charge so battery banks became obsolete and the buses suddenly got about a ton or more lighter ;D
They have been used long enough to reach the half million cycles and be swapped out for new ones (apparently, nothing wrong with the ones removed)
Of course, there are probably a few thousand under the floor but if Germany says it's OK it must be safe? ???
The 'super~ultra' capacitors are only available in low voltages as far as I know? Most are 2.7v
Charge balancing circuits are available for larger size caps
The cost ramps up dramatically for larger sizes but they can be in the thousands of Farad range and are used instead of batteries

I was going to charge pack up again tonight, turned the power supply to zero, connected alligator clips and, it was showing 10.4volts after sitting at least 24 hrs
I turned voltage up to 14.1 and none went over 5.50v plus, the lower reading ones from yesterdays testing had come up so all are getting closer voltage which is probably a good thing ;D
