CAPACITY
150 ampere hours. Lithium batteries provide consistent power for
all 150 amp hours. MaxLi LiFePO4 batteries have a flat voltage
curve, which means they have a steady power output as the battery
discharges.
LIFECYCLES (BATTERY LIFESPAN)
Up to 100% capacity for 3,000 cycles in recommended conditions. The
typical SLA has 400 cycles. Lithium batteries last so long that the
price per use is a fraction of traditional batteries.
Smart Built-in BMS
passive balancing (active balance optional), low voltage cutoff,
high voltage cutoff, short circuit protection and temperature
protection for increased performance and longer life. Besides,
Bluetooth function for option that enables to monitor battery
status, such as, voltage, capacity and so on.
