Bättre UPS.. den här verkar inte "smart" iaf 
En sådan enkel åtgärd som en temperatursensor borde vara enkelt tycker man..
DanielD67 säger iaf "I can tell you how to adjust the voltage on Smart-UPS 1000: the charging control circuit is IC14 APC2020 and on pin 13 is a resistive divisor of +24VFET formed by R118-100k and R119-22K1. Reducing R118 by adding another 5M6 you can reduce the charging voltage at 27.4V."
