Additional information:

Joule Case Lithium (Li) modules are intended for the professional or power user. Lithium offers a greater total lifecycle, more consistent discharge, more available power in a smaller form-factor and about half the weight.

Li Modules are your ideal if your application has any of the following:

  • High Power Demands
  • Weight or size constraints
  • Short Runtime (1-10 hours)

In a direct cost comparison of life cycles to dollars, Lithium is equally priced to our SLA options. Hands-down, we recommend Li Modules for any application.

See the image below for ‘load’ characteristics of our Lithium cells. For any questions about performance or properly sizing your Joule Case system let us know.

More available energy during heavy discharge than SLA modules.
