A thousand of any cell in series is a thousand times the voltage... but a 3700 V and 10 A-h pack is not useful. A more useful arrangement would be to connect groups of ten in parallel (for ten times the capacity but the same voltage), then a hundred of those groups in series, to be a 370 V and 100 A-h pack with the same thousand cells (if they were actually 10 A-h cellsif these are 3.7v, if i bought a 1000 of them would i have a 3700v battery pack or a 370 volt pack?
or does it not work like that?
