If you have a charger that is Lipo capable (needs a Constant Current/Constant Voltage mode), you can save a lot by getting the KOK3200-20C-2S-DNS https://www.fmadirect.com/site/fma.h...roducts&cat=28
Same cells, but without the bells and whistles.
I have two of these packs. The difference is they don't require the Scorpion Charger and they do not have a low voltage cut off circuit. We have a couple of ICE chargers with temperature sensors for charging. I don't worry about the low voltage cut-off. I keep track of charge state by measuring it and checking package voltage with a DVM. It is very repeatable. Using an LRP Brushless in the PRO 4, we use up only 1200 mah in a 5 minute race. If you use the FMA Lipo calculator you'll see that you can safely pull about 2800 mah from these cells so discharge is not really an issue. Using an 11T with a QC2, I use 1400 mah in the other PRO 4.
