Worth the price to have the extra capacity!
"This battery is awesome, I got a couple extra, one for my flashlight and one for my headlamp as I do things off grid fairly often and always want to have extra capacity to be able to run the lights at their strongest levels, though I havent had to use them since they one in the units work so good!"
