What power supply?

I just bought 2 ICE chargers. I need to know how big of a power supply I am going to need to run both of them. They go to 10 amps each so should I get a 20-30 amp? Thanks, Jeff

So 20 amps is enough for both chargers to run off of?

hi guys want to ask if someone have tried this. does your muchmore power master world edition 2 can handle all of this equipments. if you are using all at the same time. 2 chargers (1 muchmore and 1 novak millenium), 1 battery fan 12v, 1 teamwave discharger tray, 1 muchmore thermoelectric motor cooler and a tire warmers (ctxw ic)?

Basically a power supply has that much amt of amps to supply. Lets say if you have 2 chargers running concurrently charging @ 6 amps each, then both have already taken up 12 amps from your power supply. Say if you have 20 amps to spare then you've 8amps left. The 8 amps can power other stuff like a MM motor cooler and probably consume 2amps then you're left with 6amps and so on...

You should check out how much amps each of your equipment need and get the power supply thats required.

cheers...

Integy makes a real cool one, it has dual 18 amp or 36 amp and you could run a tire truer on it. I think its on the integy website if you want to see it. Its low profile and blue. A must see.

The MuchMore Worlds 2 power supply is small and very portable and at the same time delivers 24amps. I run two cell masters and a motor master off it (not more then two of the three are going at the same time).

If price is an issue, then head to Radio Shack and get a 24amp for around $100.

Do you plan on charging with both chargers at 10 amps??

Even so, its a function of watts. If you did charge at 10 amps and both batteries were peaking at the same time at say around 9.3 volts

9.3 volts times 10 amps = 93 watts
93 watts times 2= total wattage of 186.

NOW, divide that wattage by the voltage output of the powersupply to obtain the current draw(amps) being pulled from the power supply.
Therefore, 186/12= 15.5 amps.

It is unrealistic to charge with both chargers at the same time at 10 amps, as most people don't charge that high. I recommend 6-7 volts for optimum performance and life of the battery.

So, using the same calculation;
7 amps at 9.3 volts =84 watts, times 2= 168 watts
168/12= 14 amps from the power supply.

I have a 14 amps PS and I routinely charge two packs at the same time with no problems. (Charging at 6-7 amps with both, sometimes even higher.)

PS: most power supplies put out around 13.8 volts, so the amp draw is even less at the power supply.

Here's mine :



It's 40 amp switching powersupply .... with adjustable voltage.
Compact / light (+/- 2 kgs), yet powerful .... I use for all heavy duty RC works :
3 chargers, 2 dischargers and 1 (my friend's) tire truer all at the same time.

If you interested, check this out :

But I think he sell too expensive. (Mine is just USD 65)

Best Deal Ever! $71 after regular shipping! I can run 3 chargers off it, a 4th charger for doing motor break-ins and then a DC fan i rigged up for cooling me off/cooling off motors after a race!

Thanks alot guys. You answered all my questions and then some (PitCrew) . I dont plan on charging that high yet. When I got out of pan cars 11 years ago, we charged at 3 amps....now there doing 7. Just wanted to make sure I was going to have a little extra if I needed it. The most I should be charging at will be 6 or 7 amps on each. I do want to look at the fans everyone is talking about that I can just hook up to the power supply. So 16 amps max. Thanks again guys.

BTW....someone showed me the pro peak dual outlet supply the other day. Looks like it could be cleaner setup with the dual outlets. Anyone used one or know if there anygood? Thanks, Jeff
