If you are tired of carrying the heavy Gel/Led-acid batteries about then why not consider our new range of Lithium-ion batteries. At only a fraction of the weight the advantages are much greater, the dimensions are also much smaller allowing you to simply pop it in your pocket! Other advantages are a built in fuel gauge allowing you to see what charge you have left and a flat discharge rate meaning the light stays brighter for longer. Batteries come complete with charger. Please note, by law, lithium batteries higher than 8Ah should not be transported on passenger flights (always check with your airline before travel).
