Was the bench test discharge rate the same as the discharge rate in the air?

Perhaps ththisefect only shows up when you discharge the battery at high rate. Could even be a poor connection somewhere.
Like I said, the charger could only discharge at 2.5A. The fault only shows up in the air at full throttle when I'm asking the pack to put out probably 8A continuous. It worked fine at 2/3 throttle.

I looked for a bad solder joint on the Deans connector but they both looked fine. I put the same Deans plug on the new pack and it's fine.

Cheers, Joe

Possibly a a bad connection inside the pack or worse yet inside a cell. (read fire hazard due to heat)

Voltage drop across such a problem connection would increase as current increased.

Some of my connectors at work have to suffer up to 10 Amps pulsed at about 2200 Volts peak to peak at 6 Mhz. I get a lot worn out connectors, sometimes solder joints get melted.
