Hey Ven, do you know the working voltage for the rc40vn battery pack??? Example X65VN battery pack is 12 - 16.8.

8.4v iirc

Re: RC40vn670 - RC40vn40 - X65vn2470 - TK75vn1670

Can we use the battery till it reach 6 v??

8.4 fully charged - I am testing the lower limit and will update tomorrow

Not sure on lowest limit NL, 4 lights is 80%+ so 1 light is 20% up to near 40% which would be 2 lights. When i have measured fully charged i am getting around 8.14 from memory which is around 90% charged. Good in ways as less stress on the cells over time..............

ok -
fully charged 8.36V -
fully discharged 5.70v (the driver kept dropping into lower output levels)
I didn't test below 5.70v

Thanks.. I can calculate the runtime based on the 5.7v discharge.

I run the 3 minutes straight at 70 percent which is translate to 28,000 lumen for rc40vn40. It did well. The light is warm to medium hot after 3 minutes. Great heatsink!. i conclude i can get 15 minutes runtime before the battery pack reach 6.0v.. ( 70% mode )...


just an estimate.. @ 8000 lumen, the runtime will be 52 minutes.

I am exceedingly excited to receive my TK75vnQ70 package from Vinh and literally this blows away anything stock out there. I had a nightmare because I was looking at the stock Nitecore EA81 and psychologically stock flashlights are associated with my old toxic workplace environment. Vinh's custom flashlights are literally restoring my sanity.

i recall the Fenix RC40's mAh of its battery to be higher, and impressed me more than Acebeam's X65. I hope this feedback helps you a little bit, NL. I am impressed by RC40's 7,800mAh versus 6,400mAh with X65! 👨

Re: RC40vn670 - RC40vn40 - X65vn2470 - TK75vn1670

They are different packs S&R, set up different (series/parallel inside along with 6 and 8 cells) for different LED voltages. The rc40vn40 is on vtc5 cells, these are 2600mah. The standard rc40 is fed on 2600mah sanyo cells, so 2s3p(iirc) would give you 8.4v and 3p which is 3x 2600mah=7800mah...............if makes sense. The x65vn has 3400mah cells , 4x4.2v so 4s=16.8v then 2p= 3400mah+3400mah = 6800 4s2p i presume the set up for the acebeam.

Re: RC40vn670 - RC40vn40 - X65vn2470 - TK75vn1670

For sure, works great. I call it a high output flooder. Power flooder and long reach. Definitely brighter than stock X65 without the washout blue tint that otherwise ruined it. Error-free UI. I accidentally knocked it flying to the ground from my bed table with my pillow and it is perfectly fine. This is like the dream Surefire M6-CB in LED. Yes Surefire M6-CB in LED! Vinh finally invented it!!👨

I have tk75vnq70 diffuse dome. I like it better than tn36utvn or m43vn, because 17k lumen is damn bright and I can use extended runtime kit...

thats look like a rc40vn mini.. this light got to be 21000 lumen.

Wait a minute......... I thought the 2015 version of the TK75 had 4 LEDs. I wasn't aware of this beauty!
