They are 2000MAH (so 2AH?) at 3.6V. So I put them in series in 4 (14.4volts) to run the car (thats what my car uses running with the alternator). So each series of 4 only has 2AH? So for a total of 60 AH I need 20 series = 80 batteries?? That sounds like a lot of batteries... my math has to be wrong lol |
I would like to clarify something before you really put 20 of these in series and blow everithing electronic up in your car : )
Staying with your battery example:
You would either need to put 4 n series (14.4V 2Ah) and then 30 of these series packs in PARALLEL (2Ah X 30 = 60 Ah )
OR
30 cells in parallel (60 Ah at 3.7V) and 4 of these packs in SERIES (60Ah at 14.4V)
So 120 cells either way.
I would do the first version.
Not being picky just making sure you got the theory down regardless of your battery choice.
