Hello all, almost a year ago I bought a cheap beolit12 which had a battery pack that would not hold charge anymore. This didnt bother me as the unit stayed mostly in the kitchen plugged into the wall.

But now I feel the need to give this beaut little speaker some freedom.

I've opened up the battery pack (quite messily I must admit, as i wasnt sure where the internal components were situated inside) And may have permamntly damaged the circuitry (using the knife I used to cut open the plastic housing)

My first question is

Can you even buy a new Beolit12 battery pack? and if so where?

Second one is , have I damaged mine ? please see photo attached

And third, if I havent damaged mine can I replace the original battery cells with something with a much higher capacity, but with the same physical size, voltage etc.

Something like these - 

Panasonic NCR18650B 3400mAh 3.7v Li-ion MH12210 ...

I look forward to you replies.

No one has ever found a replacement battery pack online? or even rebuilt one themselves?

Hi,

I'm not an expert here but as nobody answered yet, here is my experience…

If the whole form factor of the battery is still intact or close to (i.e the battery still fit into is compartment), then yes you may rebuilt the battery with individual spare cells. You must be able to find the original cells reference on your original battery, just google any marking you'll find on it. Keep any other component such as thermal sensors or anything and and keep a good reference of any internal wiring.

Soldering that king of batteries may be difficult but not impossible. And of course once done, I'll would keep an eye on the device and never let it plug alone without surveillance for a certain period. Just in case…

I've done that several times with Beo6 battery (it's quite common) and have heard about various battery reconstruction without any problem.

Hope it helps.
