I bought this 10AH battery a year ago now. Installed on my glider, it provides more than enough electrical energy that I need (radio + navigation + Power Flarm + 2 indicators V8 and Flarm) even in case of flight of more than 6 hours.
I know that it is well built and that the protections avoid any risk of untimely heating in flight. I think it will serve me for a long time.
