Professional factory made modules look at those busbars. Hope she doesn't mind us talking about her can't wait or you to take these apart with pics.
 
Take them appart is easy,i dont have them for free :lol:
I have to check al the modules for ballans and healty voltage first,the ones i already checkt are al 23.04V 6s 2p/3.83V for the 2p cells.

Hope to get 23-24Ah out of the cells on a test,i can only test 7s 10s 13s battery.so 7S 25V 25Ah pack next week and test them whit the battery condition test machine.Hope these cells have a low IR and good enery...i,am happy with 579Wh out of a 7S 1P pack....maby they have more energy bud i have to test them a view times.Post the results here.
 
Discharge the 7S 1P pack.
charge 4.2V cell.
End discharge 3.10V
Discharge Amps 13A continue
IR 14 Milliohm :lol:
Discharge time 2 hours.

Result:25.87Ah 666,47Wh for the 7S 1p pack so singel cell wil store 95.21Wh.

Results are perfect.
