MKR 1010 Wifi Battery

Official Hardware MKR Family MKR WiFi 1010

Hello,

Let me start by saying I know the documentation lists that the battery you should use for the MKR 1010 WiFi is the Li-Po battery 1024 mAh minimum, JST PH connector.

However, I purchased one of those and I believe the connector is too small for the board. I think I'm supposed to get a JST PH 2.0 connector but I cannot find one anywhere that has the minimum 1024 mAh minimum.

The 2.0 li-po batteries that I've found are all a lower mAh.

Would anyone be able to link me to a li-po battery that I could buy that they know works?

Thank you.

I'm using the MKR 1000 - not sure if the connectors are different although they sure look exactly the same on the store's screenshots - and have been using this li-po battery which charges well:

Amazon also has something similar

You should be able to use any lipo with a JST PH connector, at least 1000mAh. The issue with MKR1000 is that the charge current is 350mA and runs for 4h so it does not make sense to use more than ~1400mAh (although 2000mAh is ok). The MKR1010 seems to have "at least 512mAh" which may indicate it charges faster and can use larger lipos.

IMHO JST-PH-2 and JST-PHR-2 is the same. Both have two female connectors with a distance of 2mm and should fit. E.g. by googling "lipo 2000mAh JST-PH" I get many other hits and all on the first page seem ok.

Thank you for the response, I'll give that battery a shot!

I received some response from Arduino: It seems the MKR 1010 has a more modern charging circuit and may support up to 10,000 mAh 3.7V lipos w/ max. charging current of 2A and maximum time of 5h. I'm going to try this out but it will take some time.... This will also need a microUSB power supply that can deliver 2.4A. For 2000mAh any microUSB power supply should work since it needs not more than 500mAh.
Best, Alex

I tried the battery option, doesnot work for me - found this - more expensive, but, much better "packaged" How to power your MKR IoT Carrier with a battery – Arduino Help Center

I should definitely note that PH connectors have no standard on the positioning of Ground (black cable) and Power (red cable), so you get different versions. So please check the connectors before plugging it in! If the connector is wrong, it is often possible to switch the connectors by removing them carefully from the PH housing and swapping them before reinsertion.

CAREFUL: Don't let the open connectors touch, otherwise instant short circuit which is very bad for lithium ion batteries.
