I like this one: http://www.batteryspace.com/pcbfor74vli ... limit.aspx. And you need the 7.4v smart charger from batteryspace to use with it, but unfortunately it takes FOREVER to charge.
If I understand correctly, a CBM is different from a PCM by offering the ability to charge and play. That is the case with the CMB posted previously
Sorry for bumping an old thread but the PTR08100 diagram is wrong. The resistor should be between pins 5 and 3. I was referencing this diagram today since it is so nicely drawn but realized after I wired it up that it was wrong, luckily I didnt kill it.
One Question. Which diagram is the right one? Is the issue fixed with the swapped positive and negative Pins?
