Hi guys im new to the electric side of things , i have done nitro for many years but would like a bit of indoor electric racing

I have got myself a 1/10 schumacher couger sv second hand but looks in great condition , i also have all my electrics and radio gear

the one thing i havent got is my batteries

what to go for ? saddle packs , stick packs ??????

any help would be great , and even better if anyone has anything for sale at right price

Thanks
