In the digital era, lithium-ion batteries (lithium batteries for short) have become a crucial force in energy transition considering the advantages of high energy density, 1 long lifecycles, and easy deployment of intelli-gent technologies. Lithium batteries are widely used, from small-sized. One of the most significant advantages of lithium iron phosphate batteries in solar applications is their ability to be deeply discharged without damage. As lithium-ion batteries undergo repeated charging and discharging cycles, their internal. Smart BMS: 20+ protections (including over-charge, over-discharge, over-current, over-temp, short-circuit protections); overload protection with auto-recovery (30s); low-temperature cut-off protection; better resistance of salt spray. With advanced liquid cooling, IP55.
