I sourced some Venom LiPo's (3S 11.1V 4000mAH) from Tower hobbies and they sold me a bunch of duds.
The batteries seem to drain after just 7 mins of flight and now the charger refuses to charge them, because they are bloated and 'damaged'.
I did take care in using a balance charger and a blinky to equalize the cells and was pretty careful about not letting the battery discharge too much.
What more can i do to avoid battery damage?
I blame tower hobbies for selling me lemons. Incidentally even for the Airtronics radio that i bought from them, the battery drains in under 15 minutes after a full charge.
So i would also appreciate it if i could be pointed to reliable brands/online stores.
