I should get my I-Power 12volt 20amp power supply soon, will post pics when i have finished building the clear perspex box and done all the wiring etc, its a pretty gutsy power supply because its a 2 channel one, my CDC's i am getting each take a max of 7amp but i might end up only charging at 5amp (7amp would kill my new 3300's real quick)

it would be pretty cool to fit a neon in the box but maybe thats going overboard !

Here's the one I'm using now. I put bolts thru the back of the power supply case to just plug on to. Only used the 12 volt power as my charger will run a lathe and do break in. When running the bolts thru, I drilled a hole twice the size of the bolt so the bolts wouldn't contact the metal, and used plastic washers to insulate.

It will probably work for the time being. Don't know how good it would be running the charger with that low of amperage. 10 amps or more would be much better. 12 to 15 volts is recommended for most chargers I believe. But they will run on as little as 10, and run great on 12. But with only 12 volts, you won't be able to charge things like your transmitter battery or say a starter box gel cell. But I don't know anything about your charger, maybe it wouldn't do those anyway.

How many amps does your charger charge at crACkeD ChaSsiS ? as long as you cover the amount of amps you charge with you should have no problems.

Yes, but say you charge at 6 amps, then you're only leaving your charger 1 amp to run itself. I don't know how many it takes... but that's besides the point. Running electrical appliances (charger, dishwasher, whatever) with low amps is what burns them up.

thats true jbrow1, i also heard that if you have to many amps it can also cause damage but why would people say that when car batterys have a massive amount of amps and never blow up our chargers ? doesnt make sense.

I would have thought the more amps the better !

Ya I've heard that also. But don't know if it's true or not. Way I thought it went was the appliance drew whatever amps was needed. Now to many volts,,, that's a different story. Hehe, ya know it's the amps that kill ya also, not volts if ya get electrocuted.

5amps is the border line, my local hobby shop and alot of racing regulars trackside have told me not to charge above 5amps but apparantley you are spossed to charge at 7amp to get more punch in the stock class (27 rebuildable) i wouldnt like to take a guess at the batterys long term life though charging at 7amps !

I charge at 5 amps and call it good. I see guys racing stock who charge at 7 amps. But those are guys who only consider the battery a race battery for 5 cycles.

Here's a couple more links for ya to read
