The unit can extend the lifetime of Lithium LiFePO4 batteries, if it had been set in such a way, that it
switches off before the BMS safety system against low voltage of the battery acts.
For
lithium batteries
, the unit is
not suitable
as substitute
for a
BMS
safety system of the battery!
++
Lithium LiFePO4 batteries, recommended for high load
+
Lithium LiFePO4 batteries, recommended for low or moderate load
*
Switching thresholds according to DIN EN 1789, starter batteries: Warning the driver of a battery,
which is not capable to start (such as for intervention vehicles with only one battery circuit) and of the
disconnection of additional consumer loads at this battery circuit.
