derp your right
the idea is to get as close to max out put from the charger
at ~89% to 90% efficient for the charger
so the voltage needs to be as close to 25.2v and 40amps as i can get
since thats the voltage and current going in to the packs
whats best case i can get if we limit the charger input to 40 amps? 50 amps?
edit thinking about it if i just get the one with the 50amp input i can just leave every thing as it is
but if just look at one limited to 40amps
could you build a DC/DC converter for less then 60bucks that could handle 26v and 40amps with a 24v 47amp input?
