2.4 BATTERY TEMPERATURE COMPENSATION
Battery temperature is a key factor in correct charging, the charging formula
must be adjusted (automatically and in real time) according to the actual battery
temperature to ensure that battery are fully charged but not overcharged or
undercharged. All charging voltages recommended by battery manufacture are in
fact only applied at 20°C – 25°C.
The BTS (Battery Temperature Sensor) terminated to PMDC-30 measures the
temperature of battery and automatically makes adjustments at real time to
properly charge your batteries at the default compensation rate of -3mv/°C/cell.
If the BTS is not present/connected, the PMDC-30 will use 25°C as default setting.

2.5 DE-RATE CURVE AGAINST TEMPERATURE INCREASE
PMDC-30 will monitor internal temperature to decide output power. It will
de-rate its output power against temperature increasing. Below is a curve to
reflect the change of output power with temperature increase.
