Some batteries from Ebay rated for high current. The capacity specification has a rather wide range.











There is a small difference between the cells in capacity and they can only handle about 10A





















Conclusion

This battery is not very impressive in capacity and current handling, it works fine for a few amps, but the chemistry is not for high currents.
