Battery Charge Profile
The CoolMax SRX charge output will not automatically activate for safety reasons. Prior to activating the
charge output, the charge profile must be configured for the relevant battery solution being utilized.
The SRX operates using an advanced three-stage charging process and has pre-set charge voltage profiles
for each supported nominal battery voltage. That said, AERL always recommends referring to the battery
manufacturers specifications regarding charge voltages for optimal battery life and performance.
These voltages can be adjusted in the charge profile settings. Refer to
Page 18
for instructions.

Battery Charge Profile Illustrated
IMPORTANT
The CoolMax SRX default charge profile is intended for a generic LiFePo
4
battery solution.
AERL supports most other battery chemistries that
do not
require external BMS communications.
AERL is working with various battery manufacturers to expand out-of-the-box comms support for
Lithium batteries that require communication with the Charge Controller.
Please contact AERL support to confirm compatibility prior to installation. Additional battery
support will be rolled out via Over-The-Air firmware updates.
