The Triton is programmed to stop the charge when pack voltage stabilizes at 4.2 Volts per cell.

If it's a new or discharged pack, charge it at 0.1A for 10 hours (or 0.06A for 16 hrs if you can) and try it again.

I guess they think 800 is close enough to 650 to not make a difference.

.08A = 80 ma, not 800ma

0.8A = 800ma

The voltage is not important, only the charge current. For most purposes, a charge rate of 1C or in your case, 650ma (0.65A) would be appropriate.

Great to see Thunder Power has stepped up for the customer.

The Triton does not come with polarity protection so I installed a fuse in the + lead. (Hope I never find out if it works or not.:))

Looking at just the FMA and IA-Flyers data and adjusting for a 4.17V 100% charge level, we might see a guage like this:

25% = 3.7-3.77V
50% = 3.81-3.85V
75% = 3.92-3.98V

Fred, why don't you post the 0-100% capacity vs voltage for your cells in 20% increments for comparison purposes?

The Boucher chart and the IA-Flyer chart are different - I think IA-Flyers data is on newer cells (if that makes the difference), but don't quote me on that.
