"AGM 2 14.7 V"
Switch Position
U1=14.70 V U2=13.60 V
1.5-5 h
Adapted to closed, gas-tight
AGM (absorbed glass mat)/lead-fleece
batteries
VRLA
with indicated
charging voltage "14.7 V or 14.8 V".
It is highly recommended to check the specification
sheet of the battery concerning the high
charging voltage U1
14.7 V
!
Charging Program for
LiFePO4 Batteries:
Charging program 4, charging characteristic lines and temperature control adapted to lithium batteries:
Observe the instructions of the battery manufacturer!
An operation of the unit at a LiFePO4 battery without BMS Battery Management System and
without equalization charging of the cells (balancing) as well as safety circuit is prohibited!
The battery temperature sensor must be installed at the battery (fastened to the negative pole)
and must be connected at the unit. It serves as protection for the battery.
No function without temperature sensor. The LEDs "Batt. Full" and "Power" are flashing
simultaneously!
If possible, the battery temperature should be kept above 0 °C.

0.3-1 h
Adapted to
Super B SB12Vxx - M (Epsilon) **
RELION types "RB" **
Büttner Elektronik Series MT-Li
of the indicated capacity rates, types, complete with
integrated safety circuit and integrated BMS.
**
Also to be used with indication "Charging Voltage:
14.6 V" because of the lower battery load.
