So the original battery:
300 wh x 29.6v
=10.135 x 1000
= 10,135mah

so i would need a 10000 mah 29.6v pack to equal the old power supply.

confusing lol

Unless Im trippin' that seems correct- you'd only need a couple 5,000mah 8s lipos in parallel it seems ( or 4x 4s 5000mah packs, wired up to get the same result ).

Depending on the brand and discharge ratings, you could build a suitable pack for as little as ~$400, though more like double that for a premium brand of battery say.

Would be interesting to have a watt-meter hooked up between the controller and batteyr to see what peak/ max current draw currently is...
