My couple year old DX80 is now holding less and less charge each charge cycle. I’ve attached a video below which depicts the exact same symptom that my DX80 screen is displaying.
Flashlight begins charging correctly from dead or low voltage. Fully charged voltage is 16.8v. the flashlight charges normally until 15.5v or 15.8v and then displays the weird error message shown in the video.
I’ve tried cleaning all contact points and using a different power adapter.
I can’t find anywhere online that sells a replacement battery pack.
When it charges to 15.5v I can turn on turbo for a couple of seconds and get it to charge up to 15.8v but nothing can be done to charge it to 16.8v fully charged
Okay I was Having the same issues I ended up taking my flashlite apart. There was a short in the battery. I was able to fix it By spot welding the battery back together I have a battery spot welder. It was a Frankenstein job As I was unable to get the battery back in the flashlight like it Was, so It hung out the Back end a little bit. It works for a couple of months but then 2 of the batteries ended up going bad. Now I’m looking at either buying a new battery pack or upgrading this one or something.
I assume the pack has a PCB circuit? I’ve seen that go bad in a couple scuba diving packs (lights, suit heater). The cells get so out of balance that the pack performance takes a hit. When the PCB was removed and cells tested the cells were actually OK.
Can the pack be yanked and charged externally (hobby charger probably) to determine if it’s the pack or the light circuit?
Addendum - From what I could find it’s an 8-cell, 3.7v light? So, 8-cells in parallel it would appear. No need for a PCB. Kind of expensive for 8x cells, but that seems to be par for proprietary packs. https://www.ledsupermall.com/imalent-dx80-battery-pack.html

I’m having the same problem. Went to charge it this morning and I know something is wrong because it only took 30 minutes or so to charge, then stopped charging. Voltage check indicates 15.9 volts. I’ll probable end up buying a new battery pack, but my light is only about 18 months old.
i would give up on imalent there are other better brands out there… u can buy new batterypack and i bet u that wont solve your issues… but if u wanna play and gamble go ahead.
$120 for a battery? What a ripoff. That’s the kind if thing that keeps me from buying those types of lights. I’d do what I could to cobble up new one. Reverse-engineer the original maybe? For that money you could buy tons of 18650’s and BMS boards and make a few batteries unless Imalent made them so complicated or proprietary that it’s not feasible to do so. Can you send a picture of what it looks like? I’d like to see inside.
Anybody?
