iCharger 308DUO Power Supply Choices
I have been looking for a new charger combo and I think I have settled on the iCharger 308 DUO. I am going to be using it for 1/8th and SCT off road racing. The max I will need it for is 2 5000 mah 4s batteries at once. Research is showing that 15a per pack should be optimal. I am looking at power supply options and have been told to look at converted server power supplies. I am torn between 2 of them. The first is 12v 62A 750w and the second is 24v 62A 1500w. It appears either may work but is there any benefit or disadvantage to getting the 24v dual unit over the single? Thank you as I have been attempting to research this for days and am now just getting confused!

Check eBay for some good deals on old server power supplies. They are cheap and powerful

Check Feather Merchant.

Yeah for 4s charging, go with a 24 volt supply. Feather merchant will hook you up. 12v 62 amp will work but you'll be pushing it pretty hard.

Except he wants to do two at once. Yes that is still within the capacity of one of the 12v supplies but doesn't leave much extra for additional use or future upgrades.

Ask Feather Merchant what he suggests.

Plus the charger itself consumes power, aka charger efficiency.
The power supply is likely in the 50 amp and 600 watt range. Doable yes, but not a lot left over. A lot of work for the voltage boost portion of the charger as mentioned earlier.

Charging a pair of 4S lipos at 15 amps each takes considerably more than 30 amps from a 12 volt power supply. The charger will need more amps at 12V to achieve the power required to drive 30 amps at the higher 16.8 maximum volts.

4S (2 x 16.8V) x 30A charge (15A ea) = 1008W
Charger is good for 800W/channel so np there.
With efficiency losses, a 24V power supply setup is what the OP would need if he wants to have these kind of charge rates. Even then, he's getting close to his limit IMO.
