I'm currently using the Thunderpower Gen 2 Lite's. Two 5S3P 6000 mah packs wired in series for a total of 10S3P. I now have over 45 flights on one pair of these packs with no problems. They weigh 45 ounces.

This powering my PL Partner with a Hacker C50 14XL Acro, Hacker master 90 controller, APC 22-12E prop. The timing is set to +3 degrees. This is making extrremely good power.

My Partner now has over 400 flights, all electric.
