Lithium batteries are frequently used for diving. An average diver’s kit contains dive computers, transmitters, diving and caving lights and perhaps a camera or underwater drone. During a diving operation, these devices are often charged on board, whereby the battery pack can overheat due to the warm environment. Also, these devices are often thrown together in the rinsing tank, which could cause damage to the battery pack. Another potential cause that could lead to damaging a battery pack is a rough sea.
These conditions create an increased risk of a thermal runaway fire on board. As described in our article on the use of lithium batteries in the marine industry, the danger of a battery fire at sea is many times greater than on land.

Lithium batteries used for underwater scooters

Underwater scooters for both professional and recreational use are also powered by powerful lithium batteries. The advantages of the lithium battery technology are very attractive for divers: the batteries are light and very strong, making it easy to cover long distances. Diver Propulsion Vehicles includes a wide range of configurations from compact, easily portable scooters with a low speed to big enclosed units capable of carrying multiple drivers at high speed.
