Several of these batteries have already been purchased. Convenient to charge separately from the lamp, for example during a run with a separate power bank. The indicator light indicates the charging status.
The battery works as it should and with my own lamp (Nitegear Helios +) the running time was long, i.e. the capacity is probably at least close to the stated value.
The only negative note is that compared to my previous battery (exactly the same model) this is about 0.8mm longer.
As a result, the lamp cover has to be twisted really tightly to make the newer battery work in the light.
Easy to charge also on the go when brought to the USB charging port.
It is always a good idea to have a spare battery with you. Really long, months delivery on order.
This is a battery. Provides power and then charges at the end of the cord. Charging indicator Plus.
Good battery, usb is a big plus.
The only downside would be to say there is no type-c connector.
USB charging should be found in all rechargeable batteries!
Good and effective.
