Just need a confirmation on my understanding.
12s3p 22650 battery Batteries using tested to 4100mah 30-31amp. Should be 12s 12300 mah 30-31amp.
12s4p 18650 battery Batteries listed at 3000mah 20 amp Should be 12s 12000 mah 20 amp.
So in theory the 22650 will take up just a little less room and have a small amount more mah and have a lot more amps given the scale.
