hello,

my brother and I have been flying a pair of parkzone P-51's for the past month. This weekend, I had two pretty rough crashes that snapped the connector on the battery, leaving bare contacts exposed on the battery and a hunk of plastic blocking female plug on the plane. I am distressed over the losses, since we are now down to three batteries between my brother and I. Attempts at repairing the damaged batteries were only partly successful and not safe. Both losses were Eflite 150mAh batteries, one brand new from the store.

so here are my questions:
1) have other people broken batteries like this before, or am I just that bad of a pilot?
2) what can I do to prevent damage to replacements? (and please don't just say 'don't crash')
3) what is the correct and safe disposal for the damaged batteries?
