Glow plug battery

Here is a 1.2v 23 ah (23000 mah) cell I am using for my plug. 20 cells like this make one 24v aircraft battery capable to deliver 1000 amps for a few seconds. This particular cell comes from airbus a 320 battery which replaced due to low capacity but still very strong for our use. So if you know someone that works in the aviation industry and can provide you a cell like this it is good to have.
