2x rcr123 LiFePO4 for nanjg/7135 linear driver

Will this just be too much voltage?

I want to build a glove compartment light using an old surefire g2z so it has to be low current. I also don’t want to use lithium primaries as I don’t want to deal with cells with different capacities/explosions. I also don’t want to leave an 18650 in the car. I understand 2 LifePo4 should be decently safe for this scenario. Correct me if wrong.

I can’t find a driver I like with mode’s I want to run an XML2 using 2xLifepo4 cells. Would the voltage just be too much for the typical linear driver?
