no power at the track options (other than generator)

[strodedawg]

After reading this thread i have some questions but here is what is the situation at the track i am dealing with:

1- obviously no power at the track so I need a power source
2- generator is not in the plans right now

my set up:
electric 5th scale racing

2x 6s 7600 mah packs (so 15,200 mah) per run
capaciity needed if i run in practice, quals and mains (assume 6 runs max) so i would need a total of 91,200 mah
charging @7.6A per pack, 15.2A total

this is my charger both AC/DC

i understand that that total capacity might not reflect what i actually need as we do not run our lipos to zero capacity

can a car battery supply that much power for a full day? is there a power bank that can handle that much charging?

any help would be appreciated
thank you

Without knowing how much time between runs you may have to show up with 6 packs (3sets) charged and rotate charging from first to last sets as the day progresses. A stand-alone decent size automotive 12v battery should be able to charge them all back up for the 6 run total

1000 wh power banks exist, but at a high cost. You'd probably be better served by using one or two car batteries. Google seems to think they are around 500 to 1000 wh per battery. I wonder if you could use several older batteries (used) and get the same results on the cheap.

Use your car/battery. Then use you charger off the car battery.

Vehicle battery can charge whatever, for days, years, if you start the engine once in a while..

Unless of course you don't want to walk to the car..

Jackery 1000 is on sale on Amazon. $350 off. Kinda pricey, but i think its worth every penny. it'll definitely be more useful than just a lipo charger PS. I take it camping mostly and even got the jackery 300 for quick bashing charges. I think I could get about 4-5 full charges on a 3s 5000mah batt out of the 300.

Nope. I’ll save $1K and use my car battery with a cheap inverter.
