Carl,
I can’t afford a M43, so I am the wrong guy to ask. - Just an interested bystander.
Contact Richard at Mountain - Since he has the batteries and will have the lights, He is the Man to ask!
Richard was part of the M43 ‘pass-a-round’ that they did, and are still doing, I believe.
He was good enough to include a set of these when he passed it along, just so everyone could be on the same playing field: (someone please correct me if I am wrong about which ones they were)
If you are in the USA, you are not gonna find a better battery seller than MTN Electronics. - Richard is ‘RMM’ here in the Forum. - Yes, He’s one of us!
You can find his ongoing sales thread here:
Thanks,
-Chuck
