Low-current charger provides battery backup from USB to 1-cell applications
https://www.electronics-lab.com/low-current-charger-provides-battery-backup-usb-1-cell-applications/
Another app note from Maxim Integrated on small current battery management.The circuit provides a 1-cell Li ion backup battery charger for low-current devices performing resistor limited current sharing. A simple circuit sometimes needs to charge a 1-cell Lithium-ion (Li+) battery from a USB power source and simultaneously provide backup power for low-current-consumption devices. The circuit […]

Researchers From NREL Discovered New Method To Develop Rechargeable Magnesium-metal Battery
https://www.electronics-lab.com/73399-2/
A team of researchers from National Renewable Energy Laboratory (NREL) has discovered a new method for developing a rechargeable non-aqueous magnesium-metal battery. A proof-of-concept paper published in Nature Chemistry. It described how the scientists pioneered a method to enable the reversible chemistry of magnesium metal in the noncorrosive carbonate-based electrolytes and tested the concept in […]
Lipo Charge/Boost/Protect board in 18650 cell holder format
https://www.electronics-lab.com/lipo-charge-boost-protect-board-18650-cell-holder-format/
Peter6960 published a new build: So couple months ago, GreatScott made a video where he designed a circuit. Nothing too innovative, just the same TP4056 charger the MT3608 Boost combined on one PCB. He did add a Lipo protection circuit though, initially using the same DW01. But then, the Aha moment from this video, he […]
