hey guys, i just re-charged my 7.2volt 3000mah battery pack that i use in my HL bulldog. i wanted to see what the voltage reading was after charging it so i used my multimeter to check the voltage output. i was surprised to see that the voltage output wasnt reading 7.2 volts but reads 8.4volts. ive used this battery several times without any problems with the tank. so im wondering if this means that the hl tanks can run on 7 cell 8.4 volt batteries without any issues. anyone have some insight on this?
