More cells, especially 21700 make the light a lot bigger. I guess the idea is to have a small-ish (for the output) light with crazy performance. It will thermal throttle anyways, so why have more batteries.
Why can’t you respond to that? I know why! Because it’s true and people only respond to what they want to respond to.
you did not respond to anything I wrote, you just wanted to restate what you stated before.
Acebeam does not want Joe avagere to start mixing batteries on a 700W light, period. If you can’t stomach the costs, don’t buy a 700W light.
Should or shouldn’t aside…
Is it even possible to make a user replaceable battery carrier that can pull full 40-50 amps from each of the 4 cells? And how fast will it blow up if something came into short?
Proprietary batteries take our hobby back in time. Rayovac was making flashlights in the 60s and 70s that used AA/C/D STANDARD batteries. Why on earth, 50 years later would you want to change a good design?
On the other hand, power tool makers do not dare allow users to replace their own cells. Proprietary does make sense here as tools are abused, dropped, and left in the sun.
I Did respond. Look at post number 41. My response was based on cost not your theory.
The cost of the light has nothing to do with it. It’s the cost to replace the battery pack and how we are at the manufacturer’s Mercy to do that. I thought that was clear.
By the way I have Three lights all modified. One is $600 and Two are over $400. One of which is modified Acebeam X65 MINI… no battery pack and no step down! 
Maybe someone should post a survey on battery pack or no battery pack. I would bet the overwhelming majority chooses to use their own batteries and does not want a battery pack for many reasons I mentioned.
The question remains, can 80k lumens be achieved using a battery carrier with the added resistance? You’d require some fairly beefy springs as well.
Sold a Convoy 4X18A and had a customer insert all 4pcs 18650 30Q in reverse with the button top adapter. Completely destroyed the flashlight along with the cells. He did this even with clear instructions and then lied about how it arrived in this condition. Had another customer do the same thing, at least this guy was honest. I imagine this could be quite an issue doing the same for a model that draws much more current.
As a flashlight store, I get nervous selling models to newbies where it takes more than one cell.
Misusing/abusing a product is never an adequate reason to redesign the product. You will destroy your car if you drive 100mph then throw it in reverse. Manufactures are really not obligated to design a product around foolish people.
If you literally dont know how to put batteries in a flashlight, you really should not own one.
Unfortunately, you can’t choose who you sell to or know their level of knowledge. What you must still do is provide a warranty and user error isn’t always something you can prove if they’re dishonest.
I do have a battery safety guide at least, so many people have no idea because very few stores will care to say anything or even know themselves.
I purchased your flashlight and the brightness is terrible, I’d like it replaced or money refunded. What battery are you using, send me a photo. Oh, it’s a BRC 5800mAh lol.
Absolutely, use coupon code:
ACEX75-90
“10) Color-changing silicone sleeve monitors the temperature of the flashlight and protects for anti-impact.”
I’m just wonderng what’s that and where is it. Any idea?
I’m having Jetboil outdoor cooking system and there in a cup/pot is silicone sleeve with gel that is changing color to orange when the temperature of water reaches 100 Celcius degrees. That’s what comes to my mind.
Definitely my next floodlight. Acebeam, what is the intensity of this X75? I noticed there is a difference in size when compare to the X50.
For a light this size, it seems the built-in Fandle is going to limit its usefulness. But otherwise it looks like a winner.
Yes indeed. I will really like to see if it is capable to deliver that 80 000 lumens.
Keep in mind that no one that reviews flashlights and tests lumens has a professional setup with a verifiable calibration light source. Everyone is using a maukka light for calibration and who knows if Maukka’s Chinese calibration light used to calibrate his integrating sphere was in fact accurate. It did have a cert, but any company can produce one of those. I would have had more trust if it was USA sourced.
I have emailed a lab in New Zealand to see how much it’ll cost to test one of Maukka’s lights I purchased 2 years ago
Thanks for the info.
I’m going to call this one true. Our forum is about those who use flashlights as a whole way too much. We tend to know good cell from bad ones. However the public in general would probably buy the very best eBay 9900 mah Trustfire batteries. You want top performance, then let the engineers do their job from top to bottom. You want some degree of variables then get into the hobby as we here have. Want a questionable out come then let the public do it.
New Acebeam X75 LED flashlight,compact size but bright, utilizes detachable, maintainable and waterproof cooling fan(IP68).The X75 flashlight emits is remarkable 80,000lms quite ideal for search&rescue,outdoor activities.
Cool flashlight!! 400 retail seems like a reasonable price. I like Acebeam stuff. If I could find one for 300 delivered I’d probably buy it.
Please forgive me for pointing this out and don’t take it as a personal dig or pettiness on my part. Your thread HERE about popping a diminutive lithium primary cell and your overall reaction to that is precisely why manufacturers have been moving to various forms of protected cells and packs (“proprietary” or otherwise). And that was a comparatively low energy density compared to much larger li-ion cells, and those being asked to deliver higher current loads such as in these lights. Even with your 12 years of carefree experience you made an oops and got pretty upset about it because it scared you (and thankfully no harm to you in the process).
In the past “we” certainly have seen bigger oopses from multi-cell li-ion lights in various forms, and the potential is no less today than it was at any of those other times for those designs. Lights that use multi cells at high loads do command a greater sense of caution and safety awareness, and since even “experienced” people don’t always do that, packs and controls are the smart way (mostly) for manufacturers to mitigate the risks - both to users and to themselves as a company that may face litigation or brand-souring complaints and commentary.
I’m not a fan of packs that remove user input and serviceability but sometimes it makes sense. It’s no different than power tools and vacuums where the demands are similar (actually often much more severe but they use different cells, too, and smart BMS in addition). What I don’t like about the trend is inflated pricing and what is often limited availability as manufacturers stop making packs available after a too-short period of time when they move on to the next models or designs and fail to support previous ones. Overall these light-monster designs are fun and at one time were the realm of enthusiasts building at home, but for the few manufacturers willing to put these out now, they do need to take their business as a whole into account, and frankly it makes much more sense to do packs, given the general behavior of end users and the relatively high potential of accidents that could be avoided. Sure, it will cost a bit more but if they would be a little more fair in the pricing of packs it wouldn’t be too horrible. I think the overall design approach of packs could be made more user friendly in some lights but they do what they do and if you don’t like it, don’t buy it, right.
Also, those were awesome raccoon pics.
