5. Installation and operation
5.1 General guidance
All batteries must be connected in parallel before series connection. Please make
sure the modules are having less than 0.1Vdc voltage difference between each
other, or ideally fully charge the modules in parallel, before connecting them in
serial to avoid capacity imbalance.
The activation voltage shall keep within the charging voltage range, lower
voltage values may cause battery cannot activate.
Imbalance between modules may occur after a period of using in serial
connection, suggest to do a fully charge of the system during 10 - 40℃ once per
month.
Up to 4 batteries can be connected in series. If the charging and discharging
equipment has a large inductance, there is a possibility of damaging mosfet, add
a pre-charge resistance to avoid this.
If the battery is entering into sleep mode after running out of power, please
charge it immediately, or at least disconnect the load to avoid over-discharging
the battery due to Long-term shelving.
When multiple batteries are connected in parallel, ensure that the voltage
difference does not exceed 0.5Vdc, to avoid battery charging each other with
high current leads to overcurrent protection between batteries.
When connecting multiple units in parallel, try to ensure that the positive and
negative terminals of each battery to the bus bar are of equal length and have the
same internal resistance.
Please keep at least 2S interval for switching on/off key frequency. Otherwise, it
may cause the battery cannot be turned on.
Please make the wire harness according to the specified wire sequence and
make sure the PIN sequence of the communication harness is the same as the
specified one. Otherwise, the battery may not work properly or be damaged.
When using the Bluetooth function, please do not let the battery covered by
metal shielding, ensure that there is no metal around the battery to shield it,
