Hello, I have two Speleotechnics NiMH helmet packs for the NOVA 5 that I would like to sell or trade for a FX3 battery. Please make an offer either on this forum or email me at <paulmoser@hotmail.com> . Does anyone have any suggestions on a more sustainable power pack for this unit? Also has anyone modified this unit with any success? Like make the head smaller? or spliced in a different power plant?
