I was on my own today. I bought a couple larger capacity packs to run in this truck. I got 2 of the SMC 120C 10600mah packs. I also took 4 of my CNHL G+ 70C 4S 5000mah packs and made 2 4S2P packs out of them. Each pair of packs got me around 27 minutes of constant running. Without having other guys to bash with, it was a lot of non-stop running vs standing and watching them while I ran mine. The only damage was a broken battery strap... so I will need to sort that out. The heavier packs need stronger straps.
