yeah if batteries were liquid you could fit a ton in there, but its unfair to think you'd ever get close, and wouldnt be practical. I thought I'd do something a bit more productive and show how many you can likely fit under most normal circumstances.
my criteria is that it has to easily fit in the frame and have room for padding. The following is the best I could find keeping clearances. the tightest fit is the single pack as it just clears into the frame. The also takes into acount the narrowing of the frame as it approaches the headtube.
Ive picked the 18650's for a safer chemestry. This would be run on a cromotor through a mini-e (in the 40-60amp range for what it pulls i believe)
my biggest question in my configurations is how do you charge it? I'm still learning about batteries, especially how to charge the batteries so they remain balanced. So I'm unsure how to go about setting up a charging station (most chargers seem preset to the voltage of the pack you buy). I'm trying to have something that means I never need to take the battery out of the frame.
Most online kits are "heres the battery, and heres the charger that you hook it up to." not sure how to charge if I had custom batteries made.
As you can see the single battery would be easiest, but also offers the least power/range from my custom setups. could someone help me understanding charging multiple batteries in frame?
pack voltages shown are nominal voltages. highest charged voltage is at 88 (staying under the mini-e's limit)
