Re: PSU's and DC-DC convters or Is There An EE In The House!?

said by SparkChaser:

Hmmm.... 24*47=1128, 30*40=1200

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?
