Hi, First Post and Problem with Thrunite Catapult XML

Hello CPFers, this is my first real post so I apologize if I am in the wrong section or if I do anything that may offend you.

Ok, so I'm just gonna go straight into it. I bought a Thrunite Catapult XML hearing nothing but praise about it. I think it's pretty awesome. I have never seen such a bright flashlight.

The other day, however, I had it tailstanding for awhile, it just lights us a room better than any other of my lights, and eventually it shut off. I checked the batteries with my other flashlight that ran on 18650s. I don't own a voltmeter. The batteries were fine, and the Catapult wasn't even hot or warm, it just would not stay on.

I left it alone for a day and then grabbed it, hoping it would work. It did, for about 3 seconds until it flickered and turned off. The longest I can manage to keep it on is about a half a second now.

I am using AW 2200 18650s and I bought the Catapult from Going Gear 3 or 4 months ago, maybe longer. The Catapult hasn't taken close to anything that could be considered a beating. Not even a scratch on it.

I cleaned my threads but couldn't think of anything else to do. Could anybody offer some advice?

Thank you all for the help in advance

Welcome to CPF, F1em

As the Catapult utilises a LED, I'll move your thread next door to LED Flashlights.

You either need to get a volt meter or sell the light and charger. I'm not trying to be a smart alec, but you shouldn't even attempt Li-Ion without a meter.

I agree, in this hobby you REALLY do need a multimeter. Take off the tail cap and jump the battery negative to the light body with a paper clip/key/coin/wire and see if it stays on. If it does then the tail cap is not working good, if it still shuts off then you are at a stop until you can get the proper tools. (Sorry, that's all I got)

Thanks for the replies even though they made me realize I have been making a dangerous mistake.

I tested the tailcap theory, and it wasn't the problem, but now I can't seem to get the light to turn on at all... paperclip or tailcap. Did I do something wrong with this paperclip battery jumping or did my batteries just die... I see why you stress the voltmeter now.

So, are there any voltmeters you would recommend for a not super serious flashlight enthusiast as myself?
And once I do purchase said meter, what would be the next step in finding out this problem?

Thanks again. This is very helpful

ha. I'm such a noob... I got some 123s and realized the problem was the batteries and not the light. I always said I wouldn't be one of those people that just posts for the slightest problems. I apologize and thank you all for your time. I will get a voltmeter so this will surely not happen again. Sorry everbody
