Just thought I would update the problem I was having. Unfortunately I finally figured it out after I had sold my Minimus and was packing it up to be shipped. So I had a pair of Tenergy 30200 LiFePO4 RCR123A 3.0V that my cousin gave me laying around. I popped one of them in the Minimus and it fit and powered up just fine. I tried one of my old Tenergy 30201 RCR123A 3.0V (3.2V) and it still would not fit. I'm guessing the difference in capacity also made one slightly bigger than the other causing my problem. I'm really regretting not having a chance to play around with the Minimus more and may just pick up another one now that I know what the problem is. Any thoughts on this??
I joined this forum so that I might post this question. I have a maximus and really enjoy it. I use it to navigate my boat duck hunting in flooded timber in Ar. I think I have a problem with my battery. When running my boat it illuminates all of the inside of the boat and helps navigate through the trees. I only get about 20 to maybe 30 mins run time. I think it overheats in that time. Even in the coldest of weather, I'm talking single digits it will run about 15 to 20 minutes and shut off. After a cool down period it will run again but usually not long. I don't think mine will come close to the advertised one hour run time on high. The main problem mine has is it will not hold a charge over a couple days if left off the charger. I use my light nearly daily. To use it I must leave it on the charger at all times. If left off the charger it will be dead in short order. I think I will contact Surefire about this but just wanted to know if all of them are like this. If left off charger does it go dead? I bought this light when they first came on the market. Maybe they needed to work a few kinks out.
Sounds to me like you got a bad battery pack in that light. Try calling Surefire, explain the issue, and they will most likely make it right.
Welcome to the forum!
The Minimus Vision has been percolating to the top of my 'buy' list for a while now, and the final straw was my backup headlamp (Petzl Zipka) finally going south on my most recent camping trip.
A good thread here, w/ good info. Thanks to all the contributors, very helpful for those of us still on the fence.
Wild guess here, but it sounds like the Minimus may have the exact same driver as the T1A. What makes this more interesting is that there is substantial evidence indicating a buck/boost driver in the SF T1A, drawing ~30% less mA from a 3.7V LiIon compared to a 2.5V CR123. Some folks who have solved fitment & electrical connectivity issues have been using LiIons in their T1A's IIRC.
... and I do know an IMR123 will fit into tighter spots compared to protected LiCo RCR123's ...
In the past we have had a light which flickered, in the present we have a light which flames, and in the future there will be a light which shines over all the land and sea.

I mostly use my Minimus for hiking, throw it in the bag just incase I get stuck on the trail longer then I expected. While I don't dislike it I wish they would upgrade it a bit, it would make the light that much more appealing. A simple battery lock out and better beam profile would be greatly appreciated. With that said it's good for camping and backpacking. It's a little bulky/heavy compared to the more common headlamps and a spotter it's not....but it's still good.
Battery lock out and a slight tweak for a bit longer runtime would be great.
I go through the headband in about a year.
After sewing the padding on it lasts longer.
