Series Strings
The batteries can be combined together in series strings to achieve higher operating
voltages by connecting the positive terminal of one battery to the negative terminal of
the next battery. The maximum number of 12.8V LiFePO4 battery that you can connect
in a series is four (4).
Below figure 2 illustrates four 12.8V LiFePO4 batteries connected in series, for a 4S1P
configuration.
4pcs 12.8V100Ah in series
Figure 2. Connecting Batteries in Series (4S1P Configuration)
Two batteries in series: 2 x 12.8V = 25.6V (nominal) for 24V applications
Three batteries in series: 3 x 12.8V = 38.4V (nominal) for 36V applications
Four batteries in series: 4 x 12.8V = 51.2V (nominal) for 48V applications
CAUTION
•
Failure to follow the following safety instructions may result in personal injuries or
damage to the equipment!
•
Do
NOT
connect more than four batteries in series. Connecting more than four
batteries in series exceeds the voltage limit of the BMS.
•
Do
NOT
short circuit the
LiFePO4
battery
•
Do
NOT
connect more than two battery strings in parallel.
•
Do
NOT
connect different batches, different types, old and new batteries in series.
