Logitech G930 Battery Upgrade

Introduction: Logitech G930 Battery Upgrade

Short guide to upgrading battery of a Wireless logitech G930 headset.

Step 1: Remove the Battery

Follow this picture to remove the existing battery

Step 2: Unsolder the Molex Plugs.

Already done in this picture, the 3 solder points on the IC board is where the wire was.

Step 3: Find a 3.7v Battery Lying Around, and Solder the Wires on the Contacts.

Red to positive, black to negative, yellow/green to the last contact.

Obviously, pick a battery with the same voltage, and preferably, also LI-ion, but with a bigger capacity (thats why its an upgrade right?)

All LI-ion battery should be 3.7v, so dont have to worry too much.

Step 4: Cut the Battery Holder

Using a rotary tool, cut the battery holder if needed to accommodate the new battery

Step 5: Plug In, Arrange Cable

Safety tip:

Dont cover back, to have access for feel/visual inspection of the replacement battery. On any signs of thermal runaway, you are able to react.

Anyways all LI-ion battery is always 3.7v, only the capacity differs due to cell arrangement.Dont worry about exploding blablabla. Only way for LI-ion to explode is an internal short leading to thermal runaway, and it dont happen instantly, theres a build up of heat during charging before it explodes.

All OEM smartphone batteries already have an integrated protection circuit. You could put one on top so you have 2 of them working, and from what I've read, the integrated one only protects against over discharge, but not over current or over-voltage. But you don't really need to worry about that with the G930 since it doesn't drain at a rate of 1-2A and the voltage is ranged at lithium 3.7-4.2.

It is probably recommended to put one on a 3rd party one since you don't really know what's in there and it won't hurt to double up on it if there is already one. And also try not to melt the plastic like the above pictures. Cut some of it off with a precision knife carefully (unless positive and negative are right next to each other, then don't do it), don't use too much solder, pre-tin wires, and minimize contact time with all components. You could also do it with 18650 batteries, but you need to get holders and definitely need protection circuits when you do that.

Wait, so you don't need the circuit protection?

I just finished this project with a 2045mAh 3.8v battery. Great instructions yo.

I've got a Samsung Galaxy Note 1 GT N7000 i9220 Battery has 3.7v 2500mAh at first it went to battery has been teaching it to charge connected quite normally and then it was charged after 5 min, the LED went off and on again and again but it has loaded not what can that be ??

Great guide! Although I ran into a problem doing this, as the middle connector (yellow cable) of the new battery I found probably didn't meet the data/signal format of the G930 and was always showing as red charge level, 5-10-15 minutes remaining.

Workaround I found so far: do the soldering to the new battery only for red and white cables, leave the middle untouched, empty. Then cut the original connection cable exactly in half. Peel the cables. Connect the original yellow back together. You can avoid cutting it altogether if you can manage the works. Then connect all the three reds and blacks together.

This way you parallel-wired the electrical supply of the new battery to the old one, and achieved 600+X mAh, but you left the yellow the way it originally was, which will ensure it gets the right way of signal. Now it will show like 8-10 hours remaining in the software, but it will be more like 20-40 hours depending on your new battery capacity.

I did this with a Samsung Note N7000 battery, so 600+2500 mAh. Still trying this out for the first time from full charge, 10 hours into it and it still shows 4/4 bars, 8 hours remaining. Will update this if anything goes wrong/different. End product looks like this.

Hope this helps someone. HF!

Just take original battery controller and solder it to new battery bank. After doing that all problems must go. I am testing it right now with new 2100mAh battery bank.

Are you still able to monitor battery life after doing this? i did this as well with 1800mah 4 terminal cell phone battery and it is still charging as of about an hour
