Nah, not really, only a few watts…

I decided to buy myself a spare battery for my front headlight.

This way I could alternate between both making sure one of them is always getting charged and for “special occasions” I could bring both of them with me if I expect to be gone for a longer period of time…

This is what I got, it seems to be compatible with what I currently have (same voltage, apparently the same plug, etc…)

We will see…

I will let you know once I receive it…

PS: If you don’t remember or understand the 1.21 gigawatts reference then maybe you need to get this…
