Professional Review for LiPo Gens Ace Batteries: I have cycled it slowly to run them in, see the capacity and matching of cells. Without have taking the battery apart yet, I can see that it is very well made, with good protection on both ends of the pack, exit of the balance wires are also very well protected. Matching of the cells is almost perfect, despite the fact that I discharged it on the below graph to 3 V/ cell, they end up with almost exactly same voltage
This pack is one of the best build LiPo packs I have ever seen! It's perfectly protected and very well designed. Damping material on front and back with extra protection between the terminal poles. They have even glued the smal balance wires, so they stay in place when being pulled.
Thumbs up to Acepow! Build quality 10 out of 10 in my book.
Acepow LiPo test continues, now the battery has 82 cycles with 10% capacity loss, 5 C charge 15 C discharge to 3 V/ cell 100% capacity, already more than twice as good as any batteries I have tried.
