I had a lousy experience with Wina 50ah in 20S configuration on my electric scooter as from my previous post: https://endless-sphere.com/forums/viewtopic.php?f=14&t=83669
Given also other negative feedback collected on the net, I have decided to abandon this brand and replace it with Winston 40ah prismatic which has more or less same size.
But I don't want to throw away all the Wina cells right away, I would prefer to use their residual capacity; so I was thinking of the following substitution plan:
- I will replace immediately the 4 wina cells which are almost dead and run on 16x wina + 4x Winston
- gradually replace wina cells individually as they are close to death
- finally reach an 20S target based solely on Winston
The rational behind this approach being:
- first of all, not to throw away cells with residual capacity, which makes me fell bad
- when there is a mixed pack, the wina will be always be the weakest link while Winston will be the strong one; so it will be the wina to suffer for deepest discharge and wider cycle while Winston will have easy cycle; therefore the new Winston cells will not suffer in the mixed usage.
I forgot to tell that I have a very efficient balance charger that will be able to balance charge the pack even in condition of huge disalignement.
What do you think of this approach?
Thanks!
