Batteries

[chubylord]

I had been using these batteries for my portable: http://www.batteryspace.com/polymer...wh-10a-rate-ul-listed-un38-3-passed-ndgr.aspx

I also have been using this PCM: http://www.batteryspace.com/pcbfor148vli-ionbatterypack4cellswith8a-1alimitwithfuelgaugesocket.aspx

Could I just swap the batteries out for these ones to save space, or would I need a new PCM and charger and all?

Thanks!
