I have recently come into the possession of several (four to be exact: M1, M2, S2 & S3 models) Convoy flashlights. On the vendor web site it says these lights have a low voltage warning. Just how does this work? What exactly does the light do to warn you of low voltage and when does it kick in? :thinking: I would appreciate any comments on this.
 
Give it a try:p


;) just use a protected cell,but in most cases even if it doesnt the light will dim and warn you before draining cell bellow what could potentially cause damage.

Happened to me on a cheap 18650 light,turned on then off,would not turn on............(unprotected) must have had a slight drain and tbh i forgot about the light.Stuck it on the i4,5hrs+ ish later good as new,4.2v.......so guess it dropped to maybe 2.5v as did not check it at time:rolleyes:

I am pretty sure that it blinks like once a second, or something like that.
I just turned mine on and will let it run down to see, hopefully I'll be paying attention when it starts to blink. I'm running a 3400ma battery in there, but it is only at about 80% charge, so hopefully the wait won't be too long.
 
Thanks, guys. I thought that a blinking light would be a good way accomplish a heads up. It just makes sense to allow the light to slowly blink through all phases and that should be warning enough. I will test one this weekend when I have more time and i will report when I get a result.
 
I guess I am the worst at this kind of testing because after a couple of hours of watching a flashlight I get distracted with something else.
Last night I turned my S2 driven at 1400 ma on medium and let it run. It was a little warm, so I decided to cool it off and put it in the freezer, with the intention of removing it in ten minutes or so. Well yeah, an hour or two later, I pulled it out and the light was on low, and blinking. The battery was at 3.25 volts. I let it warm a bit and the voltage was 3.28 volts, and the light would light on high. I put it back on medium, and 30-60 minutes later, I fell asleep. When I awoke this morning, the light was OFF. The battery voltage was 3.0. It still has three modes.

I put the battery into my MSC20 and it will not go into high.

OK... I put the battery back into the S2 on high and waited.

It ran for a while, then dropped to low and started blinking. Battery voltage is at 2.95 volts
 
Poppy, thanks for the test and report. It looks like your S2 started a warning (slow blinking) at 3.25 volts and continued down to 2.95 volts. This should be more than enough warning to change out your battery under normal conditions.
 
If you can identify the driver , or post a picture of it. I am pretty sure the newer versions of the amc based drivers have a built in lvp that kicks in at 3.6v
