I have a raspberry pi zero w that works fine with direct power supply but doesn’t boot with LiPo Shim. I see the color gradient and then the boot sequence resets. Sometimes I see the Raspberry OS screen saying “Hold shift for safe mode” but only for a second and resets right away again. I have checked the battery voltage, both 5V and 3.3V look good. There’s no schematic so I don’t know if any other pin is doing anything to force reset. Any ideas would be helpful. ---

Header soldered on? What rating etc battery are you using? ---

Yes, the header is soldered on. It’s a 3.7V, 1200mAh battery ([LiPo Battery Pack – Pimoroni](https://shop.pimoroni.com/products/lipo-battery-pack?variant=20429082183)) ---

I would think that battery is enough, assuming its fully charged? EDIT: the specs say Maximum Continuous Discharging Current 1200 ma, which should be enough for a Pi Zero. Anything else plugged into / connected to that Pi? ---

That’s what I thought, it should be enough. and it’s fully charged. Nothing connected yet. Planning to put an IR sensor but it’s just the Pi right now. ---

I don’t own one just so you know. I do have several Adafruit Power Boosts that do the same thing. I haven’t run into your issue. Mine are powering Pi Zero’s. Big beefy 3 cell 3300 MAH battery though as I have a Unicorn Hat HD and LED Shim attached. My gut feeling is a hardware fault issue? ---

So I tried another battery and that seems to work fine. Might have been battery discharge due to a short while connecting or something. I’m charging the battery to see if maybe the battery is faulty or was not actually fully charged. Thanks for your help. ---

That’s good and bad I guess. The LIPO Shim is OK, but your battery may not be? Does the battery that works have a higher MAH rating? ---

The batteries are same rating and were bought together. The other battery was charging overnight but still doesn’t work so I’m just going to toss that battery I think.
