Power supplies

Can I hook up two 10 amp power supply in parallel to get a 20 amp power supply? If yes, will I have any problems with it when I hook it up into a charger.

Can you elaborate on what charger you're using and why you think you need 20A?

I just bought a E0S0610iDuo and I also have this charger: http://www3.towerhobbies.com/cgi-bin...?&I=LXRJN7&P=7. I'm trying to charge 4 maxamps 3s 3100 with a series adapter. Buying another another one of those ps would be the cheapest route instead of buying a 20amp power supply.

I would contact the manufacturer to verify if you can parallel the supplies like that. It's unlikely that the supplies will work well in a current sharing configuration as most aren't designed as such. Unfortunately, I think the best option is to buy a new power supply. If nothing else, you can always sell the one you have to help offset the cost.

Yeah, I agree. It's unlikely that they will operate well. I can think of a way to do it that MIGHT work, but probably too convoluted to be worth it, and it wouldn't be the best solution IMO.

6s (2x3s) @ 3.1A is 104W max (with a 25% charger efficiency figure added in). Charging two of these pack arrangements requries 208w. And that's at the max 4.2v/cell, so most of the charge require lower currents.

For 208w: At 12v, that's 17.3A. But at 14.8v, that's 14A. Pretty close if you can tweak the output of your existing one to 14.8v.

If you reduce your charge current to 1.8A, you can still use your existing PS (without voltage tweaks), but will obviously increase your charge time.

If you can tweak your current output to 14.8v, you can charge dual 3s+3s packs at 2.2A and stay at the 10A limit.

Or, mod a computer PS...

I guess i'll just buy another power supply. Thanks for the help
