Question as above. I know most chargers only require 12V but will it hurt to use a 24V 13Amp power supply? Will this help balancing?
Thanks

DO NOT USE A 24V POWER SUPPLY ON A 12V CHARGER! Unless you charger is rated at 24V input you should stay below the maximum input voltage. If you apply 24 volts to a 12V charger be prepared fro smoke.

The 208B according to its input specs is good from 4.5VDC to 32VDC so a 24VDC power supply is suitable.

Thanks. It does seem to work good in that vid. I hear balancing on that charger is amazing and was wondering if I should get the same power supply. Q answered thanks

You can use a 12V or 24V as long as the power supply can deliver the current. The guy in the video is charging at 3C or 15A for a 6S 500mAh pack which is not recommended as good practice.

The DC chargers have inverts in them to step up the voltage and then recify, so if you have the 24V supply already, great, but I wouldn't buy one specifically and expect a different result. Most chargers will go to 18V input, so if you were going to buy a new power supply stick with 12/13.8V as it will give you the broadest selection of chargers to use in the future.

Yes, I also only charge on 1C .... patience ..... we are not born with it, we learn it.
That is also why 1 run 2 chargers off 1 powersupply (charge 2 batts at once at 1C), and they now make quad chargers which sell like hot cakes so you can gently charge 4 packs at once. At 1C who needs a temp probe ????
