MEET ESP32 C3 BOARD ON TOP OF A RECHARGEABLE 16340 BATTERY

MEET ESP32-C3 BOARD ON TOP OF A RECHARGEABLE 16340 BATTERY

What can be better than ESP8266 and ESP32? Maybe a battery-powered ESP32-C3 board designed to provide lower power consumption. LILYGO® has just launched an ESP32-C3 board with a rechargeable 16340 battery holder. The new board, aptly named LILYGO TTGO T-OI PLUS consumes lesser power as its SoC single-core RISC-V processor uses 5uA and 130uA in deep and light sleep modes respectively in contrast to its counterparts’ ESP8266 and ESP32 […]

MEET THE NEXT GEN LITHIUM SULFUR BATTERIES

MEET THE NEXT-GEN LITHIUM-SULFUR BATTERIES

What would you give for a battery, 5x the storage capacity of whatever you’re reading from? Well, the countdown to commercial availability for batteries of this type of capacity has already begun and it would be considerably cheaper than then currently available batteries. This radical improvement comes from using sulfur cathodes rather than graphite in lithium-ion batteries. Sulfur

Charging batteries rapidly and safely

Charging batteries rapidly and safely

Any hobbyist can charge a battery quickly, but can you do it without an explosion, excessive heating or major degradation in battery cycle life? Well many companies have managed fast charging techniques  that typically use specialized algorithms. These algorithms take into account the chemistry of the battery and some sort of non-standard charging rate curve.
