I was flying my slow stick for the 3rd time after 2 VERY succesful FIRST EVER solo flights (what a great plane to learn on)

Anyway, I didnt have my etech 1020mah 2C pack on tight enough & on a sharp bank, it came loose, swung out, & the prop hit it. The cell is dented pretty deep but NOT punctured, with NO swelling, & the pack still powers the motor fine.

Am I okay/safe to charge? Any diagnostics I can do? I'm using a GP Triton charger WITH temperature probe.

While I'm at it, any suggestions for good fire-proof containers in which to charge? (just in case)

Thanks all

Lee
