Once the cells warm up a little (from discharging) the voltage rises a little.

Weight on these is about 8.5 Oz or 240 Grams. They are 1.83 in/46.7 mm wide, 5.4 in/137.39mm long .937 in/23.81 mm thick. Basically, almost identical to an assembled side x side pack. The low voltage cut-off that is built in does work and kicks off at 5.4 volts on the nose. Good for a safety measure but don't run them until they hit the cut-off if you can help it. It's best to stop once a noticeable decrease in speed happens. I think 5.4 V was probably chosen as 6.0 V would be too agressive and under load you would experience drop-outs - 5.4 V is a good number. Testing was done on a CE Turbo 35 GFX LiPo.
