Hello everyone, I'm building a prototype of a high end dive torch, which is not the topic of this thread but is where i'm going to use the battery pack which I'm going to tell you about.
Before I need to tell you that this is about a dive torch so you will know that batteries will discharge at maximum 1C in a sealed aluminium container, equipped with a (last chance) 10 BAR overpressure safety valve.
A nominal voltage of 29,6 Volts, suitable to my application, may be provided by eight 3Ah 18650 cells in series, or a parallel of two packs of eight 3Ah 18650 in series; depending on the configuration of the torch.
Using high quality protected 18650 cells and charging them individually out of the container will be AFAIK the safest solution; however, being able to charge the whole pack inside the (unsealed) container would be appealing.
Battery management and especially Lithium battery management are arguments new to me, so please dont save anything, I'm proposing this argument to you after some research but dont worry about twisting my plans, i'll be happy to follow discussion and learn from you.
Thank you and happy photons at everyone,
Giacomo.
