(ET) New(er) cells in.



Ok, I pulled out all 30 of the old cells and realized what might have been the problem.

Last year in a bid to increase range I switched all four packs from 30 cells to 29 cells. This was to see if I got any more performance on charge by reducing the pack voltage by 1.2 volts. Answer was no, and I re-wired the rear cells back to 30 cell strings. But I left the front at 29.

I'm not sure if this alone could have done it, but it's the only oddity but that was a year ago.

Anyway, 30 new cells are in and I took the time to replace one of the rusted front side panels. Tractor looks better if a bit off color-wise. Now the charger is pulling 400 watts, 3 hours at that rate should be 30amps into the pack. Once charged I'll let it sit overnight, then charge it again tomorrow to check and refill the water. The cells I am using were used in my S10 truck a long time ago and a single string could source 200a for driving around.
