Corsair 2100 Battery replacement, with 18650, and Boom mic fix!

Recommended Posts

Posted · Original PosterOP

Let me start by saying I love the H2100 headset. I got it for 50 bucks on corsair refurb. Recently I wanted a new headset because of my battery life and the boom mic being all loose. So I took it apart and I will show you what I have done. This tutorial is for semi advanced users, just take your time and be careful. These little batteries if not handled carefully can be dangerous. This is my first post, I hope I can help someone out there.

 

First to deal with the boom mic problem...... I have had my headset so long that it has actually worn out the little nubs on the detentes. So i took an exact-o knife and cleaned up the nubs and then took a pointy soldering iron and made deeper grooves. Then cleaned up the grooves. As you can see in the first two photos. Then I tightened up that Phillips screw that holds that arm and now its nice and tight and the boom mic doesn't flop around.

Now to the battery upgrade. There is a silly little 680mAh lipo in there. So I said to myself I bet i could fit a nice 18650 battery with a 2800mAh lipo.

 

Turn on soldering iron again, and take out the battery and unplug.

 

Step one: take the right ear cup apart.

Step two: Turn on soldering iron again, and take out the battery and unplug and take battery completely out.

Step three: You need to take the platform that holds the battery, it should look something like this, after your done. 20160810_194118.jpg

Step four: Test fit battery20160810_194126.jpg

 

 

 

 

Make sure the battery is lying flat, check this by putting the ear cup back on top and make sure it sits flush.

Step five: disassemble the old battery, we need the battery management system and the connector from the little battery. This little board is the charge controller.

Step six: cut the battery off of the little pcb board. Be superrrrr careful this little battery packs a lot of punch! Do not touch any wires together. Anyway after you cut the battery off solder some wires onto the pads, as you can see i have sharpied the right hand side there with black indicating negative. Also you can tell from the wire colors and where they go.

Step seven: get some little short wires and solder them to the battery and to the BMS board. I would highly recommend buying one single legit 1860 with tabs on it, mine happens to be a LG.

Step eight: Put the battery in there and tuck the bms board in there and plug it back in. Also the BMS board had some kapton tape on it, put that back on or tape up the board so it doesnt do fun things. I realise now that you should also put a piece of from in there so the battery doesn't rattle around. Before you close everything up make sure you check all the wires and stuff, these batteries are very torquey! 

 

 

I hope you enjoyed my mod to my 2100's I thought i should post because I haven't seen anyone post anything like this before. Now I have one of the best and affordable longest lasting wireless headsets.

 

 

I have not done any testing yet because I just did this but I can post with an update with new battery life times!

Unprotected im pretty sure. Also I am on day 5 of not charging and using it for 5+ hours a day. I will be looking someday soon about the mic situation. I also will post one or two pictures I forgot to take. I just did the mod on my buddies 2100 with great success!

Nice write up. I have had my H2100 yellow for a good 2 years now and really like it. My mic has gone to garbage so I started shopping around for wireless headsets and honestly couldn't find one that fit as nice and tight as this one, so my goal is to revive it since I am only getting about 4 hours of battery life on it now. 

 

One thing to note is that if you are experiencing a hiss sound, you could consider uninstalling the corsair software and then use Razer Surround Pro. They sell it for $20; however they periodically give it for free, which is how I had gotten it. I found that the sound quality greatly improved and the hiss was gone after I moved over. The funny thing is that the H2100 sounds far better than the new Razer Man O War wireless with the same software. YMMV but I believe it was greatly due to how tight my ears fit and seal within the H2100. The Man O War has large circular cups that don't really seal.

 

Thus far the only mod I have done was replacing the ear pads with a set of memory foam with pleather cover: https://www.amazon.com/gp/product/B00MFDT894 I noticed that with these ear pads the headset seals better around the ear and it gives it more depth. They also can easily be cleaned unlike the originals.

 

For a mic I decided to pick up a Blue Snowball Ice for $45 since during my tests of different wireless headsets, I really didn't find one with a mic that I cared for. I'm considering removing the internal mic entirely when I open it up for the battery replacement.

 

Before I rip apart my headset I wanted to check with you on an update of how yours is doing with the battery mod. Here is the battery that I ordered a few weeks ago: http://www.banggood.com/Samsung-ICR18650-28A-18650-3_7V-2800mAh-Li-ion-Rechargeable-Battery-p-942043.html

 

Any updates on your battery situation? I attempted to find you with the same username on Steam in case you no longer frequent this board.

 

Thanks

The battery mod is working amazingly well. I am really surprised on how it turned out. I also have given up on the mic. I bought a snowball as well. I too as well cannot find a better wireless solution, and while these arent anything amazing they really work well and are super reliable. I am getting over 30 hours of use with my 2600mah battery, but you can buy 3200mah batteries now. I bet you could get 40 hours on a new Samsung battery. Well if you shoot me a message on reddit ill even send you a cell. I have about 200 cells so nbd. 

 

Also if you are less fond of ripping apart the headset I had another idea. Hot swap 18650. There are 18650 holders out there and all you have to do is take apart the headset and take the old battery out and then poke a tiny hole through the earcup and glue on a holder on the outside, and now infinite power. If anyone wants a tutorial on that I can probably do it easy peasy, ill even make a video.

 

I also really like the felt ear cups, not a fan of the faux leather ones. 

 

Anyone who wants to do this mod add me on steam with the same username or message me on reddit, I will be happy to help out. Reddit is prob the easiest way to get a hold of me without getting spam emails and a bunch of people on my steam.

 

Cheers!

I would like to get some help please!! I did same as on pics and now charging is working but my head set wont turn on!! Help pls

hey the headset turn on when you plug the charge? if not try seeing if all the cables didn't disconnected somehow.

when i did the mod on my h2100 i made a mistake and pulled the wire that connect direct to the soundboard, but i soldered it again and worked fine.

another thing, after i did the mod, i try to turn on and the battery wasn't charged at all, so i first thought that i fucked up the mod but i put the headset to charge for about 1-2hours and the battery started to hold the charge normal again, so try leaving charging for a bit.

its a great mod, i'm getting about 30+ hours of using, insanely good...

(sorry for my english btw, i'm still learning xd)

There is an alternative way to upgrade your H2100 battery! Bumping an old thread because I decided to change the battery on my old H2100 headset.

 

One can buy a HZSL103450A or BS140550 1700mah battery to replace the original 680/700mah unit. This unit has similar dimensions, although thicker at 10mm. It seems to have the right connector and shouldn't require any soldering work. 

 

The HZSL103450A has half the charge of a high-end Nitecore 18650 3400mah at the same price, but should be easier to install.
