Great, interchangeable Workx battery

Bought this as a spare battery that can be charging while I use the other one. Being the larger version of the battery, it gives a sensible amount of useable time and doesn't take too long to charge and has a straight forward display to show current status of charge. Love that the battery is interchangeable between all the Workx products.
