Thanks for the reassurances Subculture. I have read up on Lipos extensively, and there are many warnings posted. Also I have seen a ship at our club errupt in a pillar of smoke. Maybe the cells were charged unequally, or too much power drawn when voltage was low. I have a LiPo charger, and a LiPo guard for the sub, but cannot get the exact battery recommended as the US don't allow air export of LiPo's, so the FAA believes there is risk even on new ones. I would be more than happy to have one shipped by surface mail to get the exact size and weight for the application.
In the mean time I am gaining some practical 'sub' experience by building a semi submersible.
