AAA battery holder and a clip?

[Danne71]

Well, i finally made it!!!

This friday i bought a AAA batteryholder to my Clip+. Today i mounted it on the back of my clip+ and here are the results.

I´m very satisfied with the result!!!

It kind of defeats the purpose of it being light, tiny, and clip-able though, doesn't it?

[Danne71]

Size doesnt matter to me. Its too small even with the AAA battery holder on it. I have a hard time to find it in my large bouyancy jacket pocket when i´m paddeling.

See, I always clip mine to my shirt pocket when I use it, so it's right there, but not heavy enough to weigh down my shirt and make it flap around. But maybe for you, it will be a good solution.

Looks great - I want one! Will be very interesting to see what battery life you get.

More power to you (pun intended)--Congratulations!

Looks great!

The results are in: 31h 25m

Batteries - 3xAAA 800 mAh
Rockbox firmware 2.0
Light on for 15s
Lowest screen contrast setting
Music compression 128-320 (mostly around 192), only mp3 played
Let it play untouched 2 nights, and used it normally one day at work
All songs was played from the memory card (if that matters)
Headphones: Koss Portapro

That is pretty impressive, I must say.

Thanks for sharing, great looking mod and I’m sure it works great for many users needs. Nothing derogatory but for me the Clip is all about really good sound out of a very small light weight package for short jaunts, so it’s probably not for me, but like I said it can see this being big with many users.

BTW did you take pictures along the way? If so you should make up a tutorial for other users to see.

No, i did the case drilling at my father and i didnt bring me the camera. But i can tell you that the screw used was in size M3. The thickness of the original battery is about 3mm so when you remove it you have about 3-5mm free space for a washer and a nut. You have to cut the screw first so it doesent go through the nut all the way.

The battery holder was bought in a store called ELFA in Sweden. And the manufacter is called Keystone.

Here is a link to ELFA so you can look closer at the batteryholder. There is a link to Keystone down to the right on that page.

I will gladly answering any question about this mod.

Good luck!!!

Wow impressive. Thanks for sharing with us.
I have an 1000mAh Li-Ion battery which exactly matches the outside dimensions of the clip+. Time to drag out my soldering iron

[aarons510]

Does anybody know if attaching a second lithium ion battery in parallel with the Clip's own battery would work? It would seem that it should, since it wouldn't change the voltage, but am I missing something?

BTW, while it's not as much fun for us geeks, wouldn't the best way to increase the number of hours of music you can play be to use two players?

[Mikerman]

Or, you could get a small external battery for your Clip.

You may draw some useful information from here. I remember that one of the posters there connected batteries in parallel to arrive at a really high total capacity. Not the type of thing I would do but I can see where a hardware geek could get a lot of fun and satisfaction from customizing a player this way.

So far as having 2 players I came to the same conclusion quite a while ago. Refurbs and microsdhc cards are so cheap now that for me it's just easier to drop a second Clip/Clip+ in my carrying bag. Guards against the event of not being able to recharge and doubles my file capacity all in one shot.

First, connecting cells in parallel is not a good idea, particularly for LiOn. Second, I think the whole exercise while laudable for skill and creativity is a waste of time. While the clip or clip+ are excellent devices, they aren't so special that one couldn't find an alternate with longer battery life, it being understood that small size is no longer the governing criteria.

[Mikerman]

Or, again, just get a Lenmar Powerport Mini, about the size of the Clip and under $15 (Amazon.com has had them as low as around $8), as an external battery supply.

Danne71,
-Connect wire from battery holder directly to Clip+ pcb, without charge-controller pcb ?
-Can you monitor Battery level ? or it always shows 100% ?
-Is it charging when connected to PC ? Can it damage battery cell ?

[Danne71]

No i saved 3 cm of the original + and - cord and soldered the + and - from the batteryholder to them. It´s easier than soldering direct to the motherboard. I cut the charge controller off because i dont need it, only + and - was used.

The battery monitor works extremely well with the batterys i use (800 Mah AAA Eneloops). The best battery monitor i ever have seen, exactly as good as my Sony Ericsson cellphone. This is with RockBox installed, i cant say how the original battery meter performs since i dont use that.

No i don´t charge it with the usb cable and i don´t dare doing it. I use a stand alone charger to charge my batterys.

I have used this player the whole summer now and especially on a 2 week kayak trip. It have worked flawlessy, never a problem.
