<![CDATA[Battery issue]]>Hi,

recently I have purchased two M5Stack cores, the problem is that in both these devices battery charging doesn't work. Accoring to circuit diagram, IP5306 IC should charge built-in battery using USB port. Is there anyone out there having similar issue ?

Without it, the (2018) M5Stack works fine. As soon as I plug it in, the device shuts down unexpectedly, won't reset, won't run without USB power or simply won't power up and boot at all. Sometimes it works for a few minutes but that is the exception and not the rule. I really like the M5Stack but I won't be buying any more. I will try removing the battery from the bottom to see if that is the issue, which I suspect strongly. But then, without a working battery, the M5Stack looks is not so appealing.

It does not draw any amps. You all need to work on this issue. Plus my m5stack core doesnt hold a charge longer than a day.

JST SH - 2 pin - 1.0 pin pitch - Side mount (not top mount like many LiPo connectors)

The point about it being side mount is critical.

The plug connecting into the battery socket on the M5, should have lines on the sides that connect into the grooves that you can see in the socket on the M5. These are horizontal lines. The lines need to be around half-way up the body of the plug - not at top or bottom.

I measured with digital calipers & compared against other similarly sized JST cables of known size - so I'm pretty sure it's correct.

Remains untested at this point however.

believe the connector on that is a JST SH with 1.0 pin

Can somebody confirm 100% sure the connector format ?

Hi, probably depends whether you purchased from a reseller or from M5Stack.

I now realize the issue is with the charger chip:

  • A fully charged battery will boot the unit and it will run for a few seconds and then turn off
  • Without any battery, the M5Stack often will not power up when USB is plugged. I need to press the power button several times to get it to power up. Often, that won't even work. The same applies when powered by battery only or battery + USB power.

I now believe I have a defective M5Stack unit. How do I go about getting a replacement?

If that dosen't work, I will test battery via JST SH on main board. I have a strong suspicion the charger may not be working.

I also presumed the size is JST SH and order a battery, but I cannot confirm yet.

Hi, off hand I'm not sure which is + and -.

I believe the connector on that is a JST SH with 1.0 pin pitch with side not top mounting. But you will be doing well to have one of those on hand !! They can be purchased though.

I have the latest PS-RAM unit and there is a battery connector on the on the motherboard.
However, I haven't been able to tell which side of the connector is + and which is -.

@pkourany wich connector do you refer? I will try to test that.

My M5Stack will only work consistently with the bottom off. And yes, I tried different USB power sources which I monitored via a USB power meter. All were solid. I will try the SAM sleep mode just for kicks.

Did it improve the charging ?

Yes, it's a promising device. I'm also working on integrating it with my domotic light system and I'm having good results!

Hi, had no answer earlier.... if the pins don't look bent and if the modules fit together without issue and they are properly pushed together (no great force should be needed), then it's possible the problem might lay elsewhere. The battery itself or it's connection.....

I just found one of my units - an earlier model [not PSRAM model] - has this issue too. I connected the optional battery module and it works fine with that connected and no USB power connected. If the above is true for you, then my suggested solution is to shell out for the battery module. I know this means more $$$ but if you are to use it regularly you'd probably want it anyway. Is a great addition.

Have you seen Tom's menu system for the M5....? With the direction this thing is going in, IMO it's worth the pain of the extra $$$. It's getting more powerful by the day. (Will inspect my bottom module when I have a chance....).

As some of you stated before, must be a pin header problem.

I've tested quite a few units and I haven't had any problem with the base connecting - so I can't comment on that. Looks like reaper7 had some success with that.....

I haven't seen any code for M5Stack that shows battery charge level - there may be some out there from another device that could be adapted, but that won't help you now.

So, to step back, M5Stack works connected to the USB port which has a power transformer & no other devices connected to it. After leaving it connected for a few minutes, when you disconnect the M5Stack from USB power the M5 screen shuts off immediately? Is that right? Or does it take some time before it shuts off ?

If it's off immediately then yes seems the battery is not charging. If it stays on, its charging.

Is there any way to read from code if the battery is charging? any GPIO reading?
I'm trying to press the bottom to main board but don't know if it's working. It doesn't seem to be charging anything.

I will try to move pins but I'm afraid of breaking something. I have paid 60$ for this core module :( Not cheap and by the moment faulty.
