This is a high current cell with not that much capacity.











The two cells tracks nicely and they can deliver 30A.

I had to skip the temperature curves, I forgot to replace the battery (It last about a year).















Conclusion

The battery is a bit low in capacity, but it can deliver a lot of current.
