The Next Generation lithium batteries are a technological evolution of the previous Lithium Smart model. They can be connected in series, parallel, or a combination of both to create battery banks for system voltages of 12V, 24V, or 48V. It is possible to use up to 50 batteries when configuring a bank with 12 or 24V batteries, while up to 25 batteries can be used for a 48V bank. This allows for a maximum energy storage capacity of 192 kWh for 12V systems, up to 384 kWh for 24V systems and 128 kWh for 48V systems.
