Expensive, but a great addition.

Quite expensive for what is essentially a lithium 18650 cell in a plastic case with minimal circuitry to protect the battery on charge, but if you're in the market you already have a Nao lamp and know how well they work. These are the only effective way of extending the lighting time of your Nao for longer events or expeditions without resorting to 2xAAA batteries that only give emergency light. You'll only need one of these as a spare, as you can use a USB portable battery to charge the one not in use to give you days of powerful lighting.
