Verified Purchase(What is this?)
This review is from: Cheap 6400mAh 8.4V Rechargeable Battery Pack for Bicyle Light (Electronics)
just as the title states, cheap.
this battery is no way near the stated 6400mAh more like 2500mAh
It is no good for mountain biking as it lasts less than an hour .
it might suit road commuters
