There is a battery solution to almost every problem. The problem is: how much power, in what space, for how long? The first two are far from well explained, and - for how long? - not at all.
If you want to get serious,seems a bit excessive for the battery powered Arduino world, and would probably be the first thing you need to address.
A pair of 18650 fit in a case about 90 x 40, complete with switch.
Hello thank you for addressing my post,
the lack of info is not because of laziness its mostly because of lack of understanding,
and your questions are helpful to get my bearings.
Could you share a little information regarding the modules and circuits responsible for charging
and regulating the power output ?
I will contact eventually a professional who will design a costume PCB but I wish
a) experiment myself first
b) to gain knowledge before I contact a professional
It always feels better this way
Regarding the data:
Lets say I will choose two flat Lithium Polymer 1300 mAh (around 5C)
connected in Series.
80% would be 1040 so on paper 2.5 hours
I would need a charging module/circuit and a Stepdown module that could cope with spikes of 5A
Could you give me some orientation on parts selection or reference please ?
