So I've got these jump packs I use at work to jump start dead batteries on heavy equipment. I just decided to plug my x6 into it at 24v and 450ah rating why did I never do this before? I'm charging smaller 2s 6200mah lipo @ 2c. I wonder how many changes I'll get out of it before the x6 says no. I think for field charging with no power this might be my way to go. Or am I going to release the ghost on something?

Plenty of people do this, they would either use a car battery or use old packs to power their chargers at a tracks with no power.

that is a pretty big jump pack you have with around 10kWh of power. to charge your packs it uses around 100W at most, so TECHNICALLY it could charge it 100 times. But calculating for losses and inefficiencies Im sure it could charge it at least 50 times...but who runs 50 packs at the track anyways.

I usually don't go to outdoor track but I got a new et410.2 to hit the 1/8 track for some fun laps. I definitely won't need 50 charges. 4 is plenty for me. I just don't know why I never used it before to power my charger.
