Replacment Battery for the Marshall Kilburn Bluetooth Speaker
Hello,
So I just bought a used Marshall Kilburn Bluetooth Speaker without the battery, thinking I could easily replace it on my own...little did I realize that its not that easy. Turns out Marshall doesn't even offer a repayment battery for a product they have had out for 2 yrs now. Anyhow my next idea was to find an after market one and modify it as needed, that to is a little beyond my skill level. Here are a few facts about the battery, if there is anyone that could point me in the right direction it would be much appreciated.
Marshall Kilburn Bluetooth speaker
Battery: 4x 3.7V LI-IO Batteries with a mAH rating of 2200mAh.
Here is a link to a photo of the battery along with some photos of a replacement this guy put together: http://fr.audiofanzine.com/enceinte-mult...
Here is a Battery I think could fit the bill how ever its a 2 wire vs. the 4 wire configuration of the current one. http://www.all-battery.com/li-ion1865014...
Thx

Hey Scott, have you solved this problem?

Not as of yet, however I think that there are batteries options out that that could fit the bill. Currently Marshall does not sell a replacement for this unit, and they have intentionally configured the their battery with a 4 wire set up to ensure that its not an easy fix. I have not cracked mine open yet to see if the 4 wire setup is made deliberately complicated and ultimately could work exactly the same with a 2 wire connector...I suspect that when I open it up the 4 wires will most likely connect to 2 spots (2 Red to one and 2 Black to the other) and if that is the case this battery would fit perfectly if you modified the internal 4 wire connector to a 2 . Heres the battery I'm thinking with cover my needs: http://www.batteryspace.com/li-ion-18650...
I'm going to open it up on the end to confirm, and I will post photos.

Hi guys!
I just bought a used Marshall Kilburn on Ebay. It does not have a battery pack either, so im digging around looking for solutions. My seller does not have any of the PCBs from the battery packs.
Your post and pics from the French posting are very helpful! Two websites that are giving me a better understanding are this brief but great description of how 18650 li-ion batteries are wired together: http://www.tjinguytech.com/charging-how-.... The 3s connector with 4 wires looks similar to the pics of what is needed for the Kilburn. Also intruguing is this parts supplier pic of a 3s connector with 2 red and 2 black wires described as a JST-XH 3S balance connector: http://www.batterysupports.com/10x-jstxh.... That JST-XH is discussed as a popular connector in my first link. So chances are its the one. My biggest problem seems to be locating the right PCB that sits on the battery pack...

Karl,
Did you happen to buy yours on ebay, and does it have a hole cut into the cloth? If so, thats an intentional rip made to puncture the speaker cone behind it. I know this because mine came this way. I assume it's because originally it was a return that was sent back to Marshall then resold "damaged" to a liquidator. I gather the the Speaker is sold with out anything and a punctured grill, because Marshall doesn't want to compete with its own product so they &&^& them up before sending them out. Anyhow, I'm just mentioning it because I found that the cone in mines was punctured, but fortunately it's a very easy repair.

Yes Scott. Thats the way mine is- with the hole in the cloth. It just arrived today - after my Amazon power cable :). Tho to my untrained ear, this kilburn sounds great on the 3.5 cable. On the other hand, bluetooth connection to my phone is very spotty, volume is low or not there at all. I was not surprised by that. Maybe mine was returned for that reason? I didnt remove the speakers to check them physically, maybe tomorrow if i have time... i did contact my seller "Moonnqueen" to ask about the battery pack pcb, and they stated they "no longer "have them. I did trace the battery wire to a CN2A1 board connectorwhere both red wires join and connect to one point next to the two black wires doing the same.
