Why a power supply

[jj2003]

It's an Astron RM 50-M from Astron Corp in Irvine CA. I picked it up several years ago at Winter Warmups from a racer who had a few he was selling for $65 ea.. Couldn't resist. I installed the dual input banana plug-ins myself. Been happy ever since (except for the hernia from moving it)

EDIT : I cautiously ( living not far from West Hollywood "Boys Town") googled ASTRON and found this :

Likely a King's ransom for a new one 'tho

What I'm doing is setting up 2 icharger 4010's along with one TP1430. I'm going to give my son the TP610 to charge the 2s batts for his sc10. I'm using a number of 10s batts in 2p for the speedfreak and a few 5s and 6s in series for the CF cat. If I'm charging up 2 10s batts at once @3c and 2 5s and 2 6s batts at once @3c, I think I'll be running low on power(watts) available to me. I'm having difficulty applying a formula to figure out what my max charge rate is while charging 6 batteries at once.

You don't say what capacity your batteries are, but if I assume 5000mAh you would be pumping 2646W into them to charge at the 3C rate you want, assuming 80% efficiency for the chargers you need 3175W of power supply to charge all your cells at 3C.

Do you have a lake in your garden? I only charge at 1C or below at home, the rate doesn't matter too much to me as however fast I charge I can only get one charge in at home so there is no point in stressing the cells more than I have to. Field charging is another matter though as when I am at the lake charging at a higher rate will give me more runs and more fun.
