16340 for Olight s10

Can somebody please recommend a specific 16340 that will be suitable for an Olight S10 baton?
From what I’ve read there can be issues with these rechargeable batteries being slightly longer than standard cr123s and I want to ensure I buy batteries that will fit. Thanks in advance for your help.

Why not get the Olight 16340 ORB2-163P06
I got one to fit my On the Road M3

get olights own 16340 would be best?

Efest 16340 V2 are the best 16340 available

Agreed. I’ve got 12 of them and they’re great. That said, I haven’t had good luck with Olight or Nitecore 16340’s

Will those Efest’s fit the S10 Baton? Are they unprotected?

Hi Paul. They fit no problem. And yes, they are unprotected.

Ok I ’ll try them for my OTR M3 it has low voltage indicator. It does quickly suck the power from the Olight 16340

I use XTAR 16340 650mAh
