5. Installazione e collegamento

The DATOUBOSS LiFePO4 battery supports flexible connection options to meet various voltagee requisiti di capacità.

Collegamenti in serie e parallelo

This battery can be connected in series (S) to increase voltage or in parallel (P) to increase capacity. It supports configurations up to 4 series and 4 parallel (4S4P).

• Series Connection (S): Connect the positive terminal of one battery to the negative terminal of the next to increase the total voltage. Per esempioample, 4 batteries in series (4S) will create a 48V (51.2V nominal) system.
• Parallel Connection (P): Connect positive terminals together and negative terminals together to increase the total capacity. For example, 4 batteries in parallel (4P) will create a 12V 1200Ah system.
• Serie-Parallelo Combinato (4S4P): This configuration allows for a 48V (51.2V) 1200Ah Li-ion battery pack, delivering a maximum of 61.44kWh energy and up to 40.96kW load power.

Always ensure all batteries in a series or parallel bank are of the same type, capacity, and state of charge before connecting. Use appropriate gauge cables and M8 terminal bolts for secure connections.
