JBL Flip 3 – Stealth edition battery change


Hello JBL Users.

If you’re here, it’s probably that you didn’t find what you were seeking from your google search and your youtube search.

Why do I know this? I wrote this post because I didn’t find what I was seeking through my search.
And because I didn’t find what I was looking for, or the results ended up being chucking my JBL in the bin as a result. I decided to go a little Loco and figure out the process myself.

As you know, JBL Flip speakers sometimes need a little battery update. Sometimes the battery slides right out, and we can slip our Amazon purchased battery in in less than 10 minutes. Other times, we’re left with wires dangling, speakers half screwed in and a butter knife stuck down the body of the speaker.

That’s right! When there’s too much glue, it makes it difficult to get the battery out of the microscopic plastic hole. Either because JBL use way too much, or because they use radioactive quality glue, the battery stays stuck and we the users are left with essentially a door stopper or a library book stop.
Now, I don’t know about you, but I refuse to give in to this num-nuts idea of putting a speaker in the bin because I can’t get the battery out.

My first idea was to create an identical speaker body made out of wood. Perhaps I would get an even nicer sound too? Perhaps. Then, I figured it would be more expensive in electricity and rotary tool bits in addition to the wood and time. So I gave up on that idea, even if it seems pretty nice to have a hand-made speaker case.

My second idea was, drill a hole in the side, slide the wire in and let the battery dangle on the side or create a little case for the external battery. As a result of this, I now have a speaker that works, with a good enough battery to last 10 hours, and I don’t have to replace a second hand 40 euro portable speaker.

If you’ve made it until now, I’m going to assume that you’ve already taken off your speakers and have a box with dangly wires and a table full of screws… Otherwise have a look at this youtube video as an example before so. https://youtu.be/ynOI-OMTn2M


At the top, there is a demi-circle (normally used for attaching a strap of some sort…)
I decided to use a micro rotary tool saw, but you can use a serated knife (it’ll do the trick…).
This will ensure that you can get the wires through to the motherboard to plug the battery in.
Assure that you have your power adapter stuck back in also, otherwise your device won’t have access to power.
Once the hole was cut. I decided to break the little plastic bar for the strap,
so I could slide the wire through the hole and then through the cut hole at the top
of the speaker body.
as you can see, the wires go from the battery, through the hole, and then through the
hole I cut.
On the other-side of the holes, plug the battery in and ensure everything is in place.
Once done, it should look like this. Rescrew your speakers on to the body, and apply
the command protection rubber. (This tends to keep your device dry in water somehow.).
Once everything screwed on etc. Your device will no longer be water proof, but you’ll be able to turn it on
instead of having to chuck it in the bin. Which is an improvement if you’re not seeking to buy another speaker just yet. I use this for my art room, so if it gets paint splash on it I don’t mind.
For those of you wondering about the wires and the battery.

I decided to wrap my battery in some sort of insulation foil, and then I wrapped that in an adhesive tape,
and taped it to the body of the speaker. The isolation protects it from direct heats and the wiring doesn’t get twisted in the mean time.
