you know... its not recomemended but i havent had a problem with it..... you can just re charge two protected li ion cells in series without the 7.4v PCB... works for me and hasnt had ANY problems. same for eco. but its NOT recomemded. if youre using the 7.4v PCB make sure you wire it to NON PROTECTED LI ION CELLS. i tried doing a 7.4v PCB to allready protected cells and it caused me all sorts of problems. lol. so i said to heck with it, removed the PCB and it worked. but make sure you wire them properly. li ions can get dangerous if wired wrong. like they go BOOM.
