rjmcgough Posted April 21, 2012 Share Posted April 21, 2012 today I built a battery pack out of cells. But it did not work in my gun. My smart charger recognizes it however and turns green to indicate a full charge. Each cell also heats up slightly so i know all the cells are getting power. Heres a rough diagram of what I did Link to comment Share on other sites More sharing options...

Heres a rough diagram of what I did From your diagram you've built a 7.2V pack. Depending on the mAh rate of each cell you may not have enough power to turn the motor. Have you checked with a voltmeter that you are actually getting power at the connecter? Link to comment Share on other sites More sharing options...

RR01 Posted April 22, 2012 Share Posted April 22, 2012 The mah of each cell is 1500mah Could be the voltage. Although I use 7.4V Lipos on some of my rifles, the one that has an 8.4V NihM will stop working when the voltage drops in the pack below about 8V. Try the same gun with a fully charged 8.4V pack. If it works then your home made pack isn't man enough for the job, therefore add an extra cell to it. Link to comment Share on other sites More sharing options...
rjmcgough Posted April 22, 2012 Author Share Posted April 22, 2012 worked it out. person i bought the gun from was running a 9.6v batetry. Because it was used like this for a long time I am experiencing motor lock Link to comment Share on other sites More sharing options...
