Nick Flowers Posted October 24, 2019 Report Share Posted October 24, 2019 A friend of mine interested in maritime affairs has sent me this link https://gcaptain.com/safety-concerns-for-hybrid-electric-ships/ When I was working, I powered my equipment off Lithium Ion batteries and even then (over ten years ago) there were severe restrictions on taking such batteries on aircraft. Do recordists still use Li Ion batteries for location recording - and have there been any nasty incidents using them? Quote Link to comment Share on other sites More sharing options...
David Waelder Posted October 25, 2019 Report Share Posted October 25, 2019 There are a good many Lithium Ion batteries in common use for location recording. Many power supplies for recorders and accessories use NP-1 batteries. While Nickel Metal Hydride batteries are still available and in use, most NP-1's today are Lithium Ion because of the design's light weight and greater capacity. Aaton Cantar recorders, both the X2 and the X3 are usually powered from Lithium Ion batteries - a proprietary design for the X2 and a type 2054 cell for the X3. I don't know of any nasty incidents that have been determined to be caused by Lithium cells but there was a very serious fire on a dive boat in the Channel Islands off the California coast that may have been caused by overheated batteries. The boat was out on a diving excursion and anchored off the coast of Santa Cruz Island for the night. A fire started in or near the galley and spread throughout the boat very rapidly. The crew attempted a rescue of the passengers but were driven back by intense heat and flames. Most of the crew were able to evacuate but one crew member and thirty four passengers died in the fire. Early suspicion centered on the many batteries for underwater lights and cameras that were being charged in the galley and also in the sleeping quarters. From reports there were many batteries and multiple power strips. An investigation has so far been inconclusive.
