The reason for the protection circuit is because the barrel connector used is possible to be shorted out on some surfaces. The Protection circuit is to cover FatShark's ass incase the battery goes up in flames when inside your bag. Unfortunately the protection circuit then means you can't balance charge the battery. I did tell them a simple fix would be to put a flush mount switch on the top of the case and therefore not need a protection circuit at all and I hope one day they will do that.

FinalGlideAus I assume you're talking about that lipo version of the battery. I actually took apart two of those a while back and found no protection circuit. I was rather alarmed by that. does the 18650 case have any sort of protection circuit inside it? I wasn't able to figure out how to take it apart which is why I have a ghetto wire tapped to the outside. by balance charging the 18650 inside the case, the protection circuit shouldn't come into play and shouldn't be tripped if there even is one. I've already charged through at least 5 cycles in the case and it charged perfectly fine. I experimented by charging the cells in 2S format outside the case and it took equally as long so I figured the case isn't doing anything to hinder charging. nice to know that fatshark is at least aware of the convenience issues. it's unfortunate that they just choose to do nothing about it.

I actually haven't asked if the new 18650 case specifically does have one but I think it does. I'll ask next time I get a chance. I've always hated the protection circuit as well and trying to convince them to adopted a simple switch which will fix all the issues and still cover their ass. Another reason for no balance wire where you put it on was because it's a moving part and the wire would fatigue over time. I'm trying to convince them to think of a solution though. I agree one should be able to charge from the case. It's only sensible in my book.

@Kabab

FinalGlideAus yes the moving part was what I figure was the real reason why they didn't do it. I imagine if they connected the bottom batt connector to the door hinge and then designed a wire trace to the hinge pin, it should get a solid enough connection to balance charge. for now, I'll keep charging inside the case with my mod. worst case I kill a few cycles on the cells and they last only 4 years instead of 5.

MR kabab have you had any issues with the power wire having a short and dont supply power till u wiggle it? i know i need to take apart and check contacts but i think having it in the goggle strap causes the issue

How long do those panasonic 18650's last you?

You can take off the back of the case by unsnaping 2 snaps and peeling off the sticker on the back and unscrewing 2 screws then the whole back comes off and then you can cleanly add the rest of the balance circuit

what awg wire should i use for the mod? 24awg?

My lipo charger refuses to charge a lipo without the charge leads connected. So I was forced to add the balance wire into the connector just to be able to charge the damn thing.

Yeah, this case is great. I bought a cheap 18650 charger and have two sets of cells. That's just my preference, I do like your case mod. I might have done that had I not bought the second set of cells.

There is another solution! Banggood sell a case for 18650 batteries, so you buy two of those. One you mod with the balance lead for charging and the other you add a lipo monitor LED and switch for use on the goggles. Costs about $5 altogether. I've tried to incorporate the balance connection all into one case but it gets a bit messy and you really don't want a short on these things. Which is also why I can't understand FS refusal to add an on/off switch.

speaking of this case!!

Received the same FS Li-Ion cell battery case (and have the same NCR18650B Li-Ion cells by the way). I wish to use it in Aomway Commander V1 googles. Had the same idea about adding a third wire for simpler balancing to avoid taking out the Li-Ion cells out. I see that I'm not alone here :) In my case seems I must add a longer cable with jack connector, because in Aomway's distance between battery and googles is more than twice longer. But cables and connectors are still somewhere in way from China to me :/ By the way didn't expected that FS Li-Ion cell case will be so large :) It does fit in back of google head strap anyway and thanks God, aren't heavy. 2x3400 mAh cells should be enough for 6-7 hours - for me it mean possibility of flying without battery swap all day long, which is nice :) Protection circuits for multi-cell LiPo battery set somewhat area used for internal balancing between cells to make charges in all cells equal. Then only 2 wires are needed for charging. Of course, main question about such circuit build quality still remain. At yesterday some Chinese guy decided to ate Li-Ion phone battery. Seems it wasn't so tasty as it look. Surveilance video here - kzread.info/dash/bejne/e6p-s8aul9qqkso.html

I use 18650s for vaping as well so I carry 2-3 charged pairs anyway. I like being able to still use my goggles while the other batteries are charging. I have the Nitecore digicharger D4 for charging and it provides information on each cell and it makes me feel a bit safer. Not being able to charge in the box means you only need to buy ONE box and just change the batteries out. It seems like such a minor gripe. First world quad problems. :D P.S. Im using this box on skyzones 2 v+, lol

6 hours nonstop? Wow. I am sure I don't get anywhere near that long before my goggles start beeping at me.

I'll delete my previous comment, you figured out how they do cheap balancing. FYI, since you don't want to look Beto with tape I'll let you know a secret. Heat the label up on each end a little (top and bottom) on the side with the instructions. Not the side with the big name FatShark. You will find a Philip screw in the middle on each end under the label. It has plenty of room for you to run the wire inside. Tip: With the battery door open you can reach inside to get the first clip in-clipped then work you way around to pop the other clips. For me I personally don't like running 18650 cells in series without cell protection, I took it apart and discovered FatShark didn't include and thermal runaway cell protection. All the grounds for the barrel plug and the fan plug and negative of the cells run to the same solder points on the battery monitor circuit. Same with the positive wires. So I don't think it has protection, but I need to look up the data sheet for the STI chip to see how they stopped yours from charging. Mine looks like it would charge if I tried it. Well I ended up cutting the springs in half to use my protected cells, or flat top unprotected cells if I decided I wanted to. Now it works with both. Also, does your headset cut out at 7.5V? It has enough room about the positive plate to add a boost like some home made kits have done. I might do that later? But I'm also running two 3200mA cells, so I'll probably have more then enough run time without it and never get down to 7.5V.

@Kabab

Ha no need to delete comments. I also found the screw later too but my case still looks ghetto because I'm lazy. The low voltage cut off on the goggles doesn't bother me at all. I still get a solid 5hrs on them with the two 18650's. That's a whole weekend and then some. That being said, SatFark really could have done a better job on this case. At least added an on/off button like Chad recommended. Since they screwed up the low voltage alarm inside the headset they could have also added a boost too as you said.

@GadgetReviewVideos

Kabab FPV True on both. I'll add that they could have added thermal runaway protection for anytime you out 18650 cells in series. Or at least moved the contact plate back to that space I can add the voltage boot into and allow protected cells. They say on the case it was designed for ICR cells probably because they used to be considered the safest chemistry of 18650. But then Panasonic made a safer and better longer lasting NCR, but they don't mention that they can be used. Even my cells that are non protected cells but have a button top (not flat top for positive) are a very very tight fit. I didn't expected to have to mod this on day one, disappointing. If I knew I was going to mod it I could have built a better one for less, but I was lazy and decided to just buy this case. My mistake I guess. I ended up removing the positive plate spring, cutting it in half and soldering it back on the plate backwards so the smaller round loop wouldn't accidentally short out the positive side of the cell. I just cut the negative spring since it's all negative at the bottom of the cell and no chance of shorting it out. It's a choice on charging I guess, I have a separate charger for 18650 and 14500, 26650, and others that fit. So I'de rather charge them separate and top them off while using my hobby charger for my LiPo packs at the same time. The sad part is I just opened the headset box and it's my second one. It has a hair inside between the right LCD and the lens. The first one had a dead pixel in the middle of the left LCD, the hair is worse. Quality control hasn't impressed me so far with FatShark as a new customer. I'm thinking about instead of a third exchange maybe just opening this one and removing the hair since I have a microscope. I don't think it had any warranty void stickers on it. Still again for the money I expected better quality control.

I personally wouldn't do this. I seen to many accidents in the vaping world charging through a balance port. Looks like the batteries are run in series in the 18650 Fatshark battery holder so one cell is going to take a beating. IMO I would externally charge and keel the batteries married and rotate the way they go in each time so one battery isn't being abused more and the health of the batteries stay the same as much as possible.

Lipo and Li ion are the same thing, they are exactly the same chemistry inside the only difference is that a lithium polymer battery is in a soft polymer case and the lithium ion is in a hard steel cylindrical case but they are essentially exactly the same battery inside. Lipo batterys are not dangerous if treated with respect, only damage or abuse causes them to have a tantrum. If you don't damage or charge incorrectly they will behave themselves.
