WTB: 90Ah (or 100Ah) Winston cells x 9

Post by Bryce » Thu, 28 Sep 2017, 06:33

Hi everyone - am trying to fix a former Blade Getz that over discharged its battery pack recently and wiped out 9 cells in the process. Does anyone have any they would like to sell? The owner is not flush with cash and would struggle to afford the cost of 9 new ones. (Apart from the vagaries of trying to mix old and new cells in one pack!).

PM me via this forum or phone (03) 9596 3600.

Many thanks for looking

Any idea on how much capacity the remaining cells have? I'm guessing you couldn't just get away with bypassing 9 cells and lowering the motorcontroller low voltage limit?

Good question - however it's a 96V system - dropping 15V would be a deal-breaker and pulling out another 10 or so would make it's range just that bit too low!

Cheers

I have a number of Winston & Thundersky (LYP & LFP chemistry) cells from a previous house battery bank. I also have some Sinopoly 100Ah cells the same size as the 90Ah Winston/Thundersky cells. What capacity/voltage drop at what CA rating are you looking for?

Hi Terry - they're Thundersky LFP90Ah.
Max charge current is 3C, standard charge current is 0.3C.
Size: 217mm x 61mm x 145 mm. (Although exact size is not that important - can reconfigure the blocks to suit anything close to that).
Vmax 4.25V, Vmin 2.5V.

Thanks for looking!

Cheers

Terry, I'm chasing some cells for a camper trailer (so 20A load max). How much are you looking for per cell?
