Brushless lawnmower battery question

[lincpimp]

Hmm, you would need 4 6s 5000mah lipos, wired in parallel to get the same/similar runtime. Some sort of digital display or lvc would be a good idea to monitor the voltage. Or maybe go with the new flat a123 packs. 8s of them would be great, make 2 big 4s packs wire them in series to power the mower, and then parallel them and use a car battery charger to charge them individually. They can handle 5c+ chare, so 20anmps or more would be fine.

They are 4500mah. or 4.5ah. So you would need 4 of them (4s) to get around the 20ah you have right now. that would be 8 of the 2s packs, x2 to get 8s total. 400 bucks.

But 4 good 6s lipos would be at least 300 bucks...
