Thanks, all good points there. I would have to treat the charging process as I do my phone. I’ve never liked leaving lithium batteries of any chemistry on trickle charge. Even the laptop gets disconnected once charged and I try to only charge lithium powered gear to about 90-95. The RV has a LiFe battery pack and only charge the cells to 3.45V, which is around 95-98, not worth the risk chasing the extra few percent, especially when they cost a bomb to replace.

Had a look at a review of the R50 Pro by maukka and noticed the charger trickles once full which is not good. I’m very much hands on and it’s easy to keep an eye on this stuff living out of an RV on the road but there will be times I forget so would have to be careful if I buy this light. Not a good look for Olight.

Buying a broad range of torches should cover me if a battery in one goes flat. e.g. the X7R would substitute for the R50 Pro, the H2R for the M2R and 2x S1Rs as contigency.
