Temperature Compensation
Many charge controllers offer a Battery Temperature Sensor (BTS) that automatically adjusts the charging
parameters based on the measured battery temperature.
The temperature should be adjusted by subtracting 0.004 volt per cell from the voltage reading for every 1°C
above 25°C, or adding 0.004 volt per cell for every 1°C below 25°C.

ISCHARGING
Batteries should be sized so the rated capacity is double that of the required load. As an example, if the load will
require 50Ah on average, the battery capacity should be 100Ah. This will limit the average depth of discharge to
50% and will extend the life of the battery as shown below
