Operating voltages and main switch
The eStore Battery Management System (BMS) assesses the state of each cell in the
battery, deciding when to protect the battery by opening the main switch.
The Main Switch works as follows:

Main Switch behavior
Discharging
< 30 A, 11 – 12 V: main switch opens
> 30 A, 10 – 11.8 V: main switch opens
These are indicative values and are given as guidance only. The
main switch opening voltage depends on internal parameters such
as cell voltage and temperature, and discharge current. The indi-
cated current values are valid per single eStore.
Charging
The main switch opening voltage depends on internal parameters
such as cell voltage and temperature, and charge current. The maxi-
mum voltage above which the main switch opens is 15.2 V. Charg-
ing with the recommended charging parameters will ensure the
main switch remains closed during normal operation.
See chapter “Charging eStore” on page 23 for recommended
charging parameters.
NOTICE!
eStore can be charged with eCore or PerfectCharge MCA series charg-
ers (choose power mode; see charger manual for appropriate DIP
switch setting). Use of third party chargers is permitted. The main switch
will remain closed when charging under normal conditions if the follow-
ing charger parameters are met:
•
end of charge voltage: between 13.8 V and 14.0 V
•
maximum output 40 A (30 A recommend) per installed eStore
NOTE
Please also refer to the manual of the charger.
NOTE
Use a maximum 250 A fuse with 50.8 mm hole center distance.
