I work with a children’s home in Central America and spend about a quarter of my year down there. One of the things I do on a regular basis is drive a school bus for our work teams and home residents. We get into some pretty rough areas at times, but don’t want/need a firearm as a defense tool with all of the children present (plus it is largely against the law to have weapons where we are), so I ordered a Solar Force Gladiator to have a beefy source of light in the event of a breakdown or electrical outage (the electric grid is very unstable with frequent outages).
My question is this: I am using a solarforce XM-L2 U2 drop-in in the light that is rated for 2.7-9 volts according to SF. The light body accommodates up to four 18650’s, but it includes three ‘dummy’ cells as spacers. Do I need to use two of the dummy cells with two 18650’s to get the longest run time? I assume that 3-4 cells will run the voltage too high?
Thanks!
