There seems to be a general agreement that when testing you should pick a process and only use that process consistently.
eg only 1 model of tester and a fixed methodology of how that tester is used.
I think that idea could be slightly relaxed to allow different testers to be used simultaneously when building packs.
eg, say you have capacity to test 8 cells using tester type A and 4 cells using tester type B.
If you are making 120P packs, then 80 Cells would come from tester A and 40 cells would come from tester B
As long as your packs all have the sameproportion (eg 80,40) of cells from each type of tester, your packs should be the same capacities as each other.
If someone has access to a couple of different types of testers, it seems a shame not to be able to use them.
What does everyone think of this idea?
Edit to elaborate.
Where I am suggesting 80 from one tester and 40 from another tester, I should also have made clearer that the capacity from tester type A and the capacity from tester type B would need to be the same from across each pack
Eg average from tester A is 2000mah and average from tester B is 2100mah (for example if tester B typically reads higher than tester A)
If these average figures are kept the same across packa, the packs should still end up similar capacities.
I hope that makes things a little clearer..
