I bought the Mini Inferno 09 ARR at a discount from my local hobby shop. Iam getting all of the things that I need and now I am down to just needing a charger for the 6v 500mah receiver battery. Ihappen to have the HP5V2 wall wart for charging the pack for a Walkera helicopter. I hooked it up and it charged the battery. I kept checking for the battery warmth so I did not over charge it. Before you blast me... Yes I know that it has a 12v output and I shouldn't charge a 6v battery with 12v charger but my local hobby shop only has cheap 5.8v chargers and expensive multi chargers. After charging I checked the charge on the pack and it said 6.33 volts.

So my question is there something in line like a resistor so I can use the 12 volt charger to charge my 6 volt battery. Here are the specs for the charger

(on the charger)

Model: HP-5V2
Input: AC 100V- 240V
50Hz - 60Hz o.2 max
Output: DC 12.6 V 1.0 A

I also have a multi charger from radshack that you use on a car battery but it uses temp to figure out full charge. It will do 6, 7.2, and 9.6.

Thank you in advance.
