Hi, thanks for the question. I added another picture and put some information in the introduction.

Tobias Isakeit -

hey, thanks for this! is the battery plug simple JST or do I need to get something specific?

lfsaw - Reply

Yes, a simple JST plug (probably type ACH)

Tobias Isakeit -

Thanks for posting these instructions! I'm having trouble finding a battery that matches the one in the picture (unless I want to buy 1000 of them from Alibaba). Would this work?

Dimensions are:

thick:3mm

wide:60mm

length:70mm

Hi Clarke, the number on the battery tells the dimensions: 055070 = 5×50×70 mm (including the yellow electronics part)

Hello Tobias in the photo of the battery you provided, what is that cloth wrapped around the outside?

Chad Bishop - Reply

Hi Chad, the silver stuff ist just the wrapping of the battery. If you mean the yellow foil, this is isolation tape to protect the small controller board of the battery.

Tobias Isakeit -

Hi Tobias, any chance you could provide me with a link to purchase one of those? i cant seem to find anything but chinese dealers on aliexpress. I reside in Berlin, Germany if that any help :)

Dennis - Reply

Hi Dennis. First of all, sorry for the late answer.

The short english version: I don't have any link for you on where to get such a battery. We would very much like to offer a battery in our store.

The longer german version: Wir hatten bereits auch schon bei TE angefragt bezüglich der Batterien, aber leider noch keine Rückmeldung erhalten. Wir würden gerne bei uns im Store eine Ersatzbatterie anbieten. Du kannst gerne auch einfach mal direkt an TE schreiben, damit sie ein Feedback von den Usern direkt erhalten. Vielleicht gibt das noch Mal einen Ruck.

Tobias Isakeit -

Can I replace the battery with more capacity, like 3.7V 3000 mA?

Coop - Reply

Hi Coop, we haven't tried it yet, but I don't see any reason why not. As long as the voltage is the same there should not be any problem.

Maybe you want to check back with TE directly to be safe; this way they are aware that users are looking for replacement batteries, too.

I may have found some for sale here: https://www.aliexpress.com/item/tablet-b...

$12 each - but shipping says it could take 60 days... I'll let you guys know how quick I get mine :)

Shawn Ivie - Reply

I bought that and it works great!

Emil -

Does any one know the size of the jst plug?

Jean-Paul Dracolakis - Reply

Hi Jean-Paul, the jst plug is most likely a type ACH plug. You can find the details in the data sheet here: http://jst.de/file/download/588/ach
