Rechargeable Batteries in the Hacklab

As large, high-energy batteries become more widely available at low cost, we see more and more in the lab. This is good! They are an ideal energy source for many projects. However, like any large energy source, they must be treated with respect; mistreatment of high-energy rechargeable batteries can go very wrong, very quickly.

DO NOT leave charging batteries unattended. Ever. Full stop.

Rules for using Lithium-based batteries in the lab:

  • Storage:
    • Batteries must be stored safely in the designated storage box.
    • The terminals must be covered to prevent accidental shorting.
  • Charging:
    • Single cells may be charged using simple constant-current and constant-voltage settings.
    • Multi-cell batteries must be charged using a proper balancing circuit.
    • Batteries/cells must not be charged in parallel without additional monitoring.
    • All lithium charging must be supervised.

Risk assessment

This is work in progress, do not take it as gospel until completed.
