Low cost
Lithium battery costs less over its entire lifetime.
Weighs 75% less than lead acid. Saves fuel when used in a vehicle or a boat.
Able to deliver higher peak power for heavy loads than lead acid – continuous current as high as 250 A and surge current of 700 A.
Fast charging
Fully charges in 2 hours.
Long lifetime
Typically 4000 charging cycles, or more than 3 times the lifetime of lead acid.
High quality
Bonnen uses battery cells from the world leader CATL, and are backed by a 3-year warranty plus local after-sales service, ensuring trouble-free performance.
Built-in Battery Management System (BMS)
Ensures the safe operation of the battery by protecting it from overcharge, over-discharge and over current, thereby extending the lifetime of the battery
Battery monitoring
User can monitor the battery status through an LCD display or computer connection.
Simple connections make lithium batteries easier to deploy and use.
Bonnen can make a custom configuration to match your power, voltage and capacity needs.
