Tools and Field Equipment > Can a car battery charger be used as a power supply for charger?

My Posts This: Topic  Forum		I just ordered a hyperion duo 3 for a buddy of mine and i suggested getting a power supply. He says he has a car battery charger and honestly i am not sure if it can be used as a power supply or not?

I do not have the specs of the charger but he said he can select 2 to 20 amps on the charger.

Any help would be great.

Thanks

Dave

My Posts This: Topic  Forum		I think the reason you can't use a battery charger is how the current is transported (?) to the lipo charger. It has to be smooth whereas a battery charger supply doesn't provide this. I also think it may not produce enough amps?

Apologies for the description and if it's wrong. It's just my understanding of it...

My Posts This: Topic  Forum		I use a car battery charger (slow charger) hooked to a car battery. I hook the charger to the battery right with the charger. Works fine.

I think that's a questionable practice... but perhaps is safe..

Then, your battery act as a huge capacitor that smooth the charger.

I've read many time against this practice though, Schulze are particularly clear in their manual about that.
