Hello Guys I have a Electron powered via USB with this solar panel kit http://www.voltaicsystems.com/6-watt-kit . I have also the lipo Battery connected. My question: Is the lipo battery getting charge from the solar kit when the Electron is in Deep Sleep or Sleep?? Thanks!

@jprivacoba, the Electron LiPo will always charge when power is provided. You should be able to see the charge LED being ON when charging (OFF when battery is full). However, as is often the case, the LiPo pack that comes with the solar panel may automatically shut off when it doesn’t detect enough current draw. What are you observing that causes you to ask the question?

I think the RED charging led will turn off once the solar panel starts to provide less than 50mA of current since that is a 1/10 of the programmed 500mA charging current.

I dont know if the lipo is getting charge when i have the Particle Electron in Sleep or Deep sleep mode…

Unless you explicitly switch off the charging, the LiPo will get charged during sleep, but I think only with 100mA (by default) But that's still the same answer you got 5 months ago. So we can't really do anything against [image] jprivacoba: I dont know if the lipo is getting charge when i have the Particle Electron in Sleep or Deep sleep mode But you can try it out yourself. Discharge the LiPo, let it print out the FuelGauge.SoC() value, send the device to sleep for 24 hours while keeping it plugged in and read the SoC value again when it wakes. Then you know - we already do.

Thank you very much @ScruffR, i will try the test you sugest!

[image] ScruffR: Unless you explicitly switch off the charging, the LiPo will get charged during sleep, but I think only with 100mA (by default) The info @jprivacoba is looking for is in this post: [image] Bug Bounty: Electron not booting after battery discharges completely Troubleshooting If you apply power to the Vin terminals while the Electron is in sleep modes you will get the 100ma charge limit. [image] If you use my PMIC code to bump charging current to 1amp then once the setup loop runs the charging can go up to 1 amp. [image] Now this higher charging current will hold as long as the power applied to Vin remains regardless of charging current, so you will still be able to charge at the higher currents even in deep sleep. This should be no problem during the dayligh…

Is the 100 mA default deep sleep charging current adjustable or fixed at 100mA?
