Introduction

Flipper Zero is a portable multi-tool for pentesters and geeks in a toy-like body. It loves hacking digital stuff, such as radio protocols, access control systems, hardware and more. It's fully open-source and customizable, so you can extend it in whatever way you like.

    where is the replacement battery? what are the dimensions of the battery?

    Arni Nym -

    This kind of battery is standard, as this device is not a known brand, you will not find a Flipper Zero branded spare part batteries, indeed, it's a standard no-name Li-Po battery that is being used in this device.

    From the picture, we can guess this battery is a standard 3.7V Li-Po battery having a power capacity of 7.77W, so the capacity is indeed 2,1Ah -> so 2100 mAh of capacity.

    Note : we can observe there is a circuit protection (BMS) on this battery, I don't know how this device reports voltage, temp and other battery-related stats but these features may not work properly if BMS of the new battery is not compatible with the device firmware.

    After more research, I found the data sheet of this battery for you as the manufacturer of this device made public a lot of hardware related docs : https://cdn.flipperzero.one/FLIPPER_ZERO...

    I found dimensions are specified in it with other useful information. So I don't know which dimensions you are searching for, there are mentions on page 4 of this doc

    Brendan -

    There is also additional dimensions specified page 5 and also pictures starting page 22.

    This document has been made by the chinese laboratory in charge of thesting the safety of the battery used in the flipper zero device.

I'd say, that long screws requires PH1 screwdriver.

Evge Key -

Agree with Evge, when I read "PH0" I picked mine but they wouldn't quite fit. I had to use a PH1 (1.2 to be exact, according to toolset casing) to be able to unscrew the chasis and get to the battery (I had to only remove and plug back the battery cable to fix my problem)

João Ciocca -

Careful with those screws. They are not great quality and strip easily.

andy cooper -

Do you know what kind of these screws are?

Gugo -

Second that about the screws being low quality. Also, if your FZ battery decides it doesn't like you anymore (it shows some 50%ish max), open it (steps 1-4), disconnect it (steps 7-9), and reconnect the battery. And it seems to be something that's gonna be routine, because it happened back in October and again now in December.
When disassembling this time I checked the screws better, and it seems a 2.0 phillips is the best fit for the long screws.

João Ciocca -

Second the question for what kind of screws are being used? Size/thread?
