RC10T pinion advice

[highflier]

A123 are much safer then Lipo's They have a metal can and do not explode/flame up like Lipo's.
My charging method refered to as Zip charging, does not require buying new changers. You can make one in about 10 min for under $10.00. I use the same balancer as what I have on my lipo's. (LBA10) I balance after the charge not during. This is OK with A123 cells.

I certainly hope I am well within specs of the controller.
A stadium truck on 10 volts (under load closer to 8)

The controller BK, is a 70 amp 20 volt rating. 1400 watts.
Of course I will be at 8 Volts thus 560 watts.

A123 Cells will start to really sag voltage before they hit 70 amps. So I should be plenty safe on Voltage and Amps unless I 3s2p the packs. I have no intention of adding that kind of weight to the truck.

For secureing the batteries, I am thinking about drilling 4 holes in the bottom fo the tub,
2 on each side of the battery, then installing a velcro strap tiedown. This way I can use both velcro on the bottom of the pack and a strap on the top of the pack. I expect that to be plenty strong.
