I want to make a 12V battery pack to run an Nvidia Jetson TK1 for an afternoon. I am new to using batteries and was wondering - will mixing smaller capacity lithium ion batteries with larger capacity lithium ion batteries result in a bottle-neck &/or accelerated wear on the system?
I want to combine the voltages of these batteries to get over the 12V required to power the Jetson TK1, and thought it might be convenient to combine batteries. The prices per amp-hour are comparable, but I don't want to go way over the 12V (to 29.6V) by combining 9 of the smaller batteries.
2 x LITHIUM 3.7V 6AH (Model: ICR18650 6600mAh 3.7V 1S3P) [1528-1835-ND] $4.47 per Ah 2 X LITHIUM 3.7V 2.2AH (Model: ICR18650 2200mAh 3.7V ) [1528-1836-ND] $4.52 per Ah
From what I can tell by the model numbers, [digikey # in brackets], the candidates below are comprised of Samsung ICR18650 cells, although both the large capacity and small capacity batteries both output the same 3.7 volts.
