TP had a problem with some of their cells that caused this problem. They will promptly replace packs with bad cells. They have redesigned the cells to eliminate the problem. They prefer that you call them (their e-mails get lost a lot) and they will send you a new pack.

Swelling LiPos

Hi, your esc, motor and batterys will thank you for changing to the 14 tooth pinion. The 16 tooth puts a very heavy load on the system. I think RYOBIE should mention this in the manual or at least inform you when you buy the package form them of this change. They include the 16 tooth for a brushed, NOT brushless set up.

Hope this helps, John

that the problem right there. a 16t pinion will push the pack well past its limits. a 14t will be perfect.
