Up to now, this battery level indicator design was limited to 12 & 24V applications. In past circuits, the use of fixed resistors greatly simplifies setup. However, fixed resistors resulted in ...

Low voltage may not sound like much of a problem, but it can be a disaster due to the physical wear it puts on your tools. Here's what Ryobi does about it.

Tesla replaced the lead-acid low-voltage battery in its vehicles with a Li-ion counterpart in 2021. However, these batteries used NMC chemistry, thus having a higher voltage of 16 volts. The newer ...

Small button- or coin-cell batteries power many of the portable consumer electronics in use today. Efficiently monitoring the health and state-of-charge (SOC) of these batteries without significantly ...

The Topdon BT200 Battery and Charging System Tester showed up at exactly the right time. I’ve gotten a couple of sporadic check engine lights from a low-voltage code with no noticeable difficulty ...

Use of battery-powered systems have expanded as consumers have migrated to portable phones, MP3 players, digital cameras, and more. One reason for this growth has been the availability of batteries ...

The importance of low Iq with linear regulators and LDOs. A look at low-Iq voltage supervisors in portable electronics. Battery-voltage supervisors in the IoT. In my article “What is the Essence of ...
