DESCRIPTION

Uninterruptible Power Supply (UPS) Module, Supports Charging And Power Output At The Same Time, 3S & 5V 5A Output
Uninterruptible Power Supply Module 3S

Supports charging and power output at the same time, 3S * & 5V 5A output

 
* 3S indicates that powered by 3x 18650 Li batteries in series, the output range is about 9V~12.6V

Features At A Glance
  • Adapting various interfaces via cables, easy to integrate into mobile robots or industrial control equipment
  • I2C bus communication, monitoring the batteries voltage, current, power in real time
  • Multi battery protection circuits: over charge/discharge protection, over current protection, short circuit protection, and reverse protection, along with the equalizing charge feature, more safe and stable
  • Onboard 5V regulator, up to 5A continuous output current, more sufficient power source for Raspberry Pi and Jetson Nano
  • Batteries warning indicators, easy to check if the battery is connected correctly
  • Comes with online development resources and manual

SAFETY CAUTIONS

  • Li-ion and Li-po batteries are quite unstable. They may cause fire, personal injury, or property damage, if they're not properly recharged or used.
  • Do not reversely connect the polarities when recharging or discharging the battery. Do not use inferior charger/charging panel to recharge the battery.
  • Do not mix use old batteries with new ones, avoid using batteries of different brands.
  • When buying Lithium battery, should always make sure the battery specification is compatible with the expansion board. Choose batteries from formal manufacturer, and ensure the batteries will work stably and safely by aging test.
  • Lithium batteries have limited cycle life, they will also deteriorate as time goes by. Should be replaced with new ones when the batteries reaching their max cycle life, or working over two years, whichever comes first.
  • Should be placed carefully and properly, keep it away from inflammables and explosives articles, away from children, avoid any safety accident caused by careless storage.
