Looking at the runtime graph of the SF L2 (which in itself looks scary enough)could unprotected RCR123a's be used to increase efficency? I know I really do enjoy running my TL-2L3W on two unprotected Lith-ions and do plan on buying a Nuwai ALX-352L 5watt which I have been told runs also nicely on BatterySpace unprotected cells.
