Has anyone ever used a ZEVA precharger? Looks like a nice all in one package for precharging. I've seen it used on one build (link below) with success. The HV version comes with a built in 200 ohm resistor.

HV version is only up to 320V, so no good for 96 cell packs. Otherwise it looks like it could be useful if your controller doesn't already handle precharge.

Thanks DaveH.
Hmmm, their website mentions that it is good for a nominal of 180-360V. I think I may send them an email for clarification.

Just FYI, I did email ZEVA, and they got back to me quickly.
Looks like the nominal voltage range for their HV model is 180-360V, with support for peak voltage of 400V. The internal resistance is 100 ohm.
