Got another photo of the current wiring and my current connectors to one of my batteries and some relevant blurb from the charger handbook.
Does this mean my charger is not suitable?
Btw what appliances would be good for “harvesting “
Thanks
The 11865 cell is pretty much
ubiquitios everywhere in rechargeable appliances.
People for example buy up used laptop batteries to scavenge for cells and build anything from ebike batteries to "solar generators", ie just big power banks.
The color of the cells and manufactorer code stamped on them will help you find the specs of that particular cell.

is the best I could come up with in a casual search.
The process of building a functional batttery from used cells is rather involved and you might run the risk of a fire so do so at your own risk.
As for use in a model plane these are not ideal because as has been stated they are on the heavy side and do not allow for a big amp draw from a standard serial circuit like in your picture.
You will also have to consider your planes electronics. An "entry level" plane will most likely run something like 11.1 volts in the 10A range.
That would mean running 3 cells in series to get your voltage right. Now to get any kind of safety margin on your amp draw you would need to strap 3 or four of these in a prallel configuration for a max draw of 12 or 16 amps. This would put you at a capacity of 6000 or 8000 mAh and a weight of roughly 450 or 600 grams for your battery only which is way over board for a little 3s plane.
An FT storch for example would take a 3s 2200 mAH battery which weighs around 200grams adnd will deliver 50-60 amps easily.
Long story short: a battery made from these cells that could provide the neccessary amps for even a beginner level plane would probably be far too heavy. Much better to use these in ground based equipment.
