Hey guys!

first off, apologies if there's a blindingly obvious answer to this, but I can't find it. They say there are no stupid questions, only stupid people, so...

I have been give a well-used LED Lenser L7 with no battery cartridge. The internet gives me plenty of options for P7 and other miscellaneous overlapping models, but I cannot find any reliable information on what battery housing to buy for this L7 to get it back up and running.

Can some bright spark (pun intended) point me in the right direction or slap me upside the head, captain obvious, for sourcing the right battery cartridge for an LED Lenser L7?
