The user of one of my RTK GNSS revivers returned his unit with a power issue. He returned it to me because he couldn’t turn the unit off.
After the batteries had depleted, we can no longer turn the unit on.
Check battery voltage with a multimeter. If <3.0 V (Li-ion/LiPo), it’s likely in protection shutdown. I hope sparkfn will answer you soon.
Hi @LuckyPhil78 - Welcome! Which RTK product are you working with? What do you see on the unit when the charger is attached?

Nothing happens when the charging unit is attached.
Hmm, the next steps would be to open the unit and look at the connector board to see if there is an issue with the USB connection or the ribbons going to the main board. We would also check the battery and battery connector for damage. You’re welcome to take the unit apart, or if you’d rather have us do the repair, please start an RMA here.
