hi is the original blue charger in store here suiteble for very long charging.
am thinking to use one off these for the ez mip.cause i think he uses, more batt due he allreddy balancing while your making motions.
Any balance charger is suitable for charging any LiPo battery provided the charger is capable of charging that specific size (i.e. 2s, 3s, 4s). The two batteries you posted pictures of look like they are 2S 7.4v LiPo batteries so yes, the EZ-Robot balance port charger will charge them.
The EZ-Robot charger charges at less than 1 amp (800mA if memory serves correctly) and therefore it will take a long time to charge a 5200mAh battery (5200/800 = 6.5 hours) but it will work.
thank you very much rich.
