Lipo Battery Guide

I recently wrote this guide to lipo batteries.  In it, I discuss:

  • An in-depth explanation of battery specs – Nominal and cut-off voltage, capacity, C-rating, internal resistance and more
  • How to increase the life of your battery
  • What to look for in a battery charger
  • How to use a battery charger
  • Why balance charging is important
  • The difference between different types of battery connectors
  • Proper battery safety and care
  • A glossary of common battery terms

  • Before you use or charge any lithium battery you must read the Lithium Battery Saftety Instructions and Warnings document.
    Do not charge or use batteries if the battery ...
    is punctured or damaged
    is bloated, expanded, swelling or otherwise deformed
    has any cell with a voltage of 3.3v. This means less than 9.9v for a 3-cell/11.1v battery.
    Do not charge batteries unattended. Monitor batteries during charging for popping, hissing, smoke, sparks or fire. Also monitor the battery for any swelling or other deformities. Disconnect the battery from your charger immediately.
    Do not charge batteries near flammable material. Charge batteries in a fireproof container. Do not charge batteries while they are in your robot.

  • Hi Eric, thank you for share, it is a great post of lipo battery guide, I found a great extra post to about lipo battery guide and it include charge/discharge battery and safety. The post is more detailed than that. hope you like too.
