Please Note:
1. The number of Parallel connections is limited to 8 pieces
2. Ensure that the voltage difference between the batteries should not exceed 0.2V
before connection. If batteries do exceed 0.2V difference then all batteries will
require a full charge so they are an equal voltage.
3. Each set of the battery external cables should have the same wire diameter and
length. This keeps the current flow of each battery consistent during operation.
4. When 2~8 batteries are connected in parallel, the charge-discharge current shall
not exceed 0.5C of the total bank capacity.
2.3.2. Series Connection:
Before wiring the battery model, make sure all batteries are turned off. Follow the steps
shown below for wiring. Then press any battery's Power button one by one.
Please Note:
1. The maximum number of series connections is limited to 2 pcs - 24V.
2. Each battery should have the same capacity and the same voltage. Otherwise it will
affect subsequent use
3. Ensure that the voltage difference between the batteries should not exceed 0.2V
before connection. If batteries do exceed 0.2V difference then all batteries will
require a full charge so they are an equal voltage.
4. Connect all batteries in parallel (considering point 3 above) for 12-24 hours so that
batteries are equalized before connecting in series
5. If one battery goes into protective mode, the whole system will shut down
