I THINK the problem with the errant battery is solved (?) by a customer at the LHS where I took my Triton and battery with questions. He reset the charger with no timed out and charged each 3 series battery separately. By the way, he said he flies electric exclusively now.
So far after a couple hours, each 3S battery pack measured at 12.63 V. When I connected them in parallel (3S3P), the whole pack measured
12.63 V. It's holding, but time will tell.....If the weather is good here in Columbus (rain every day off and on), I will fly with my friend here. I'll be back with a report, maybe in a few days when I return to Toledo.
