Beginners Guide to riding Fixed/Single Speed in London

To clarify, high capacity standard nimh batteries are best for lights that get used 'in one go', i.e. high powered LED on med/long night ride.

Hybrid nimhs are better for blinkies that slowly eat batteries over the course of a few months.

On other nerdy forums like candlepowerforums and some mtb forum threads, these people get recommended all the time (and I've just bought some). Good value/quality.

Well done mate, you've expressed it better than me.
