Need help/advice on battery choice

I need help on which battery to use for my featherweight bot (which I will be entering into the Nationals in Qld) running:
- 4 12v cordless drill motors (from Kmart)

A link to a particular battery would be much appreciated. Very Happy
Thanks,
- Gary

I've been using these:

4S 3000mAh lipo's, they have a really good price/performance ratio. They do struggle a little bit with the peak current from 4 drills with grippy tires. But, a weaker battery can protect your other electronics a bit. (I went to a more powerful battery and smoked my bot lol)

If you're asking about what battery to use it might be worth reading up on the lithium polymer battery (lipo) lingo and safety precautions. You will also need a special battery charger for it, that are also available from that website.

Maddox, my ESC's are the Botbitz 30A and my wheels are the red wheels from Bunnings. (Link to wheels: https://www.bunnings.com.au/ambassador-95mm-plastic-centre-rubber-wheel_p3942877)

Ondray, thanks for the battery bud, will definitely look into them.
