so i have a 2s 5250 i bought back in june last year, ran a good number of cycles but no where near 300.
it will take a charge, store and discharge on my hyperion chargers fine, stays within .03 volts btwn cells, which is a little odd as it used to be spot on balanced at every charge up into a month ago, but still within good range.
the problem is it will not work on any of my brushless systems. other packs no problem, this one the system will react for a brief fraction of a second sometimes then shut off.
any thoughts? bad connection? it is not under the 3 year warrenty but is it something i could send in and have it checked out?
