Thanks Kolsso12,

you gave me a great tip about the XCell ( i didn't know them). This battery packs looks goog, light, powerfull and cheep enough. I think there will be less problem to balance a 10s1p pack than a 10s4p pack, maybe they can hold an higher number of cycles: "less cells, less failures"

I wish to excange with you our EP-Eclipse's experience as soon as possible.

best regards
