Hi, i have an eco power charger (an amain.com brand). It was working fine, since last charges of Nano Tech 2s packs. It charges for 30 minutes or so, then make the beep as it was full charged, but the message prompts capa lipo2, not full as usual. Then I have to press the start button and keep it charging until it is full. Do you think the batteries has something to do?. I just charged a protek 2s pack and it charged until was full. Hope you can help me.

Thanks
