I run a Losi Xxl2e with the 75c batteries, stock motor/esc and gearing. The traxxas battery I'm running with the mini e Revo. The traxxas one doesn't surprise me, all of their batteries puff on me. I've started buying SMC 90c batteries and they're phenomenal. I run them in the xxl2e, my 8ight te (even geared at 80mph), my slash on 3s and my proboat. No problems at all.

what car + motor are you running? Sounds like the packs aren't properly matched for the current you're pulling
