I have a bench power supply 1-30V with current limiting capability.

What setting should I set it to, to make it charge? The instruction say see your batteries owner manual. 300 bucks and no charger. ***?

Set your current to max amps and your voltage to max volts. Connect power supply to battery and flip the switch on. Then run fast to get away from it.

Or you can not be so cheap and buy a real charger. $300 bucks for a toy and you complain about a charger.

From the manufacturer:
Battery Charging

The 1000 mAh 7.4V lithium polymer battery pack
is equipped with a 3 pole balance charger lead that allows the battery to be
charged off standard RC battery pack chargers (not included). Follow your charger
instructions for setting up for 760 mA 7.4V Li-po. Some chargers require the
discharge cable to be connected. Use the enclosed discharge lead adapter for
these types of chargers.

I read that. Are you saying set my supply to that?
