You should ask DB Custom. He has done something similar, but used one main driver to control 4 “dummy” drivers to spread out the amperage. Even though that FET is rated to handle that amperage, the driver was not. You might fry the copper traces on the pcb or something. Best to talk to someone experienced so you dont waste time or money.
The 6500K is 6500 degrees Kelvin and is the color temperature. 6500 would be cool white. 4500K is more a neutral white like yellow/white or cream/white. The 3000K is more a strong yellow color.
The 1C, 4D and 7A further specifies the tint. It’s how Cree bins their leds into groups. The numbers just repeat the color temperature. The letters show how much green or red tint is in it.
If you look in the data sheet of Cree leds you will see a chart like this.
There is a little dotted line called the BBL, black body locus. Above this line the tints get green and below it they get red. Most people prefer the red over the green, the A and D, but it varies based on the led type and what the person prefers.
Keep in mind that Cree tests each led as it comes off the assembly line and it puts each led into both it’s color, tint and power bin. The led can fall anywhere within that bin so you can have 2 of the same bin but they measure opposite edges and can look a little different.
A 1C will have a color temp between 6100K and 6500K and be a little on the greenish side, maybe.
A 4D will have a color temp between 4250K and 4500K and be a bit on the red side, maybe.
I tried twice with no luck[ a pm and post on another thread] and still do not want to start a thread for this. Hopefully someone here takes the time and gives me the answer!
I am getting NOCTIGON K1 with Anduril firmware[First light with this]
This is about Anduril firmware. Specifically the THERMAL CONFIGURATION SETTING.
Are there any pauses or blinks to confirm each phase?
Do I simply just transition from 1. CURRENT TEMP. CALIBRATION[Thermal config. mode] Right into 2. Temperature limit?
Part of manual below
Thermal configuration Look at a thermometer to check the current room
temperature. Let us assume it says 21 Celsius.
Turn the light off and wait for its temperature to settle
to room temperature.
Go to TempCheck (from OFF: “Click Click Click”. Ascend
with double-clicks three times)
When you are in TempCheck, then click 4 times to enter
thermal config mode, and calibrate the sensor.
Thermal config mode has
two settings:
Current temperature
Calibration. Click once per
degree C to calibrate the
sensor. For our example,
the ambient temperature
is 21 C = click 21 times.
Temperature limit. This
sets the maximum
temperature the light can
reach before it will start
doing thermal regulation
to keep itself from
overheating. Click once
per degree C above 30. For example, to set the limit to
50 C, click 20 times. The default is 45 C (15 clicks).
Hint: If you don’t click, the lamp will leave the value
unchanged. The lowest value the user can set is 31 C,
by clicking once.

IF there are no pauses and/or waiting for blinks to proceed between phases,below is what it should look like.
Those are old chemistry (2012) with a ton of voltage sag. I don’t know what kind of driver the TN40S uses, but if it’s a Buck or Boost driver the voltage sag might have been too great. We saw the same issue in the BLF GT when people used 4 of the Panny B. When fully charged the voltage sag was so great that after just 10 seconds it could not stay in regulation and output suffered. I would guess the driver in the TN40S just turns off when the voltage sag can’t sustain Turbo. That’s odd, you would think they would design it to just step down to the next power level.
The cells are not protected, right? Some Boost drivers will draw more current as the battery voltage drops. This can trip protection circuits if they are low amperage like 3A.
Protected Panny B have even more voltage sag! Not good for anything drawing medium to high current. The flashlight turning off does sound like a protection circuit tripping. When one trips it puts more amperage on the others causing them to trip. I think the TN40S is 7.2 volt so 2S2P. So one cell tripping a bit early will end up cutting all power.
I use my protected Panny B in low amperage lights only. They work fine there.
The GA came out in 2015 and is the replacement for the B. It is a bit old, but the chemistry is still pretty close to current batteries. The B is rated at 4.8A continuous while the GA is rated at 10A. That’s a big difference plus there is a lot less voltage sag. I’d say the GA is a modern high capacity cell just like the LG MJ1 and Samsung 35E which also came out in 2015. They are all pretty close with max continuous output of 8 to 10 amps. The B model was truly an older generation.
See the comparison at 1A and 3A. A really big difference for about the same capacity.
At 5 amp it’s an even bigger difference. So there’s nothing wrong with the GA. It’s a good choice for when you need the highest capacity.
One factor is when were they manufactured. Just because two batteries have the same name, that does not mean they are identical if from different production lots. At times they make modifications of the electrolyte and its additives, etc. as time passes. So it might not be the same old battery. Wish they would share more with us, but they do not want to share with their competitors.
I’m not so sure about that. If they change the chemical mix then they have to go through the entire testing and safety certification procedure. If they change the mix then they usually change the name also. For example the short lived Samsung 48G that they quickly replaced with the 50E just because it was a tiny bit better.
A Panny B made and bought today should perform just like they did when they first came out. No better or worse. Just my opinion on the subject.
@JasonWW you may right, but it does happen. We do not know how often.
From docware on a different thread-
The study is dated 19.4.2017, cells are Panasonic NCR18650PD. You can read the whole study here :
The study states:
As these cathodic side reactions are not observed in the second study, it is assumed that slight changes in the functional materials, such as modifications of the electrolyte and its additives, have reduced the cathodic side reactions of the cells examined in the second aging study, which were produced several months later.
Contacted Acebeam 1 week ago and no response. I want another carrier for my X65 MINI.
Does anyone know why the K60 battery carrier does not work in the X65 MINI? Carriers[battery config.] look the same. Only difference appears to be the shape and size of contact point at either end.
Could it be the type of metal? Aluminum vs. brass like?
