Has anyone had any problems with the EFLITE lipo charger? Mine works about 20% of the time. I have 4 batteries and it will charge them differently every time. Sometimes they are good for 8 minutes, sometimes they crap out immediately. I know I need to get a good charger, but need some recommendations from you guys before I spend 150.00 on a charger that cost more than the BCP Pro originally. I need a charger that will charge TREX 450 batteries also. ANY RECOMMENDATIONS?
