so i bench tested 1 of 3, Yuasa 10ah sla dated 4-13 ( from my wal-mart ebike)
i am impressed
at 11 amps, after 6 minutes steady 11.89v.
ended test since it will not be deep cycled, and at this level there is enough power for 30-60 seconds of cranking by itself, in theory, but it will always be used in parallel, or to charge caps.
There is 0.16 amps discharge into the LA if left connected, so i'll disconnect 1 wire anytime the car sits. The LA being a marine LA, has extra terminals, so this is easy. i even used copper washers
No spring clamps, they suck
The battery is behind the seat, and i leave the seat back forward, so it is impossible to forget. Every few months i'll check the LA by itself. I only drive this car 2 or 3 times a month, just to keep it running, so i don't mind the extra work.
Interesting that a $399 walmart ebike has such good SLA's
I still use the ebike, but with 2 dewalt and 2 makita tool packs, saved like 25 pounds.
Fun with ultracaps:
i think i know how to charge the caps fast at home;
i have a 1978 10a charger. weighs 10#, i'll put a 50a bridge in it. i'll hook up the caps, and then plug it in
