CONNECTIONS
The external lead-acid baery bank is connected
to the screw terminals on the boom of the
BMS.
Each cell voltage input supports measurement
range of 0-5 VDC. Up to 10 series connected cells
may be monitored. The maximum input range of
the enre string must not exceed 36 VDC.
When less than 10 baery cells are connected,
the cells should always be wired from boom to
top, and the unconnected cells should be shorted
to the highest potenal in the baery bank.
The BMS supports connecon of a CR Magnecs
CR5210 series current transducer.
The current rmware version (3111) only
supports reporng of the CR5210-50 (± 50 A)
current transducer. Other current ranges will
operate, but the reported current from the BMS
will not be correct.
A USB type B connector and a 2.5 mm ID power
jack are on the boom of the BMS.
Both the USB connecon and the DC input will
automacally charge the internal lithium-ion
baery.
The DC input accepts a voltage range of 7 VDC to
15 VDC, with a minimum current of 2 A.
