So I discovered in my work log/contest entry that I won't be able to fit the regular 18650 batteries I had planned, and started looking at LiPo batteries.
While looking at eBay for batteries in all different sizes I started wondering whether it would be better to stack multiple smaller batteries to fill the space I have, or try to find one big one that fills the allotted amount of space?
Say I have about 64mm/70mm/9mm of space (These are not exact and there are some wiggle room)
What I have found so far is:
I can stack four 422770 1100mAh, two in height and two in width, to get a battery pack of 4400mAh 54mm/70mm/8.2mm (The margins are rather thin, and I would have to remeasure before I order, but I think I could make it work, and it is there closest I have gotten to the specs and the highest capacity)
Or say two 503450 1000mAh giving me 64/50/5 2000mAh
Edit: found a better 2x: 335865 1800mAh, stacked in height for 58mm/65mm/6.6mm 3600mAh /edit
Or one 605068 2500mAh for 50mm/68mm/6mm
Larger batteries seem to either jump up to 10mm height or 80mm length, which is both outside my specs.
It seems like I can get higher capacity and more easily fill the volume by stacking multiple smaller batteries, as there seems to be higher demand and choice in that size class, then when trying to find the perfect-sized battery. But are there downsides to doing that? Like the batteries getting hotter and more explody? stacked sizes being larger than anticipated? or other concerns?
Edit2:
Found a 3x one. 306062 1800mAh, stacked three in height for 60mm/62mm/9mm at 5600mAh. And if I can't fit it height wise, I can still run it as a 2x one with a height of only 6mm.
Which seems like a safer solution than banking on the 4x one where it is at the limits in two directions. Though the question still stands, with my best option so far being a triple layer battery, with one of the batteries being sandwiched between two other ones, is there any downsides or risks, to where trying to aim for just one perfectly sized battery would be preferable?
(also was not sure if this counted more under modding 101, or general, or somewhere else, as I did not see a battery-specific section else where)
