Even though the boat is switched off, its still drawing a small amount current. Never a good idea to leave lipos plugged in and unattended! You can try being very careful and at a very low amp rate try charging in nimh, you must pay attention and monitor the whole time. It may bring the voltage up to a level that the charger in lipo mod will recognize.
