Default Re: EPIC amp ATV

First drive at 72v- 84v fully charged. Way more power in the mid range than it had at 64v. I was told the TSX controller i have was built with 100v parts and that it would handle a charge of 99v. Well I tried and kept getting over voltage errors. I spoke with navitas and the controller is software limited to 86v. So that has prevented me from trying higher voltages. Ive pretty much decided on getting a new controller and I have some golf cart parts I can sell to offset the cost a good bit. Itll just take some time. Probably going to go with a Kelly controller of some sort.

In the mean time I was able to buy another 2 gen 3 modules so ill have 10gen 3s at 72v for 160ah. I have a wild plan using a set of contractors to switch the 72v pack to 144v a the flip of a switch. I need to see if thats somthing I can do on the fly or not. I would think its possible as the controller will likely be powered from a 12v aux battery. 72v 1000+ amps for offroad and 144v 1000+ amps for on road.
