Charge Profile Configuration
The CoolMax SRX allows for extensive flexibility when it comes to charge profile parameters to suit numerous
different modern battery chemistries and manufacturers requirements.
Our programmable charge profile allows for the configuration of the Battery Charge Rate, and the Absorb,
Float, Re-Bulk, and Equalization voltage points.
The default charge profile is suitable for most applications but to determine the optimal charge profile for your
application, please refer to your battery manufacturer’s user manual or datasheet.

IMPORTANT
An Equalization is only normally required for Flooded Lead-Acid cells that experience
sulfation because of poor charging practices over the lifetime of said cell.
Equalization is
not required,
nor recommended
for LiFePo4 or other lithium-based
battery solutions and will likely cause damage unless otherwise advised by the
battery manufacturer.
