This is a moderate capacity and current battery from LG.








The two cells tracks nicely and capacity do not drop with load, but 10A is definitely maximum current.





















Conclusion

This battery is neither high capacity or high current, both parameters are more moderate and with a end voltage of 2.75V it looks like it is a older chemistry.
The quality looks good and if the price is right and the application do not require top capacity or power it is a fine battery.
