* High safety performance.

The power battery ignition and explosion-proof experiment was tested in accordance with the

test procedures of SAE J1495-2018 battery flame retardant ventilation system. The battery did

not explode or catch fire.

* Strong cycle life.

A. Test in accordance with ISO 7176-25-2013 Wheelchair - Part 25 and IEC60254 standard

requirements: electric wheelchair batteries and chargers.

The battery cycle life is no less than 400 times, far exceeding the standard requirement of 300

times.

B. Laboratory accelerated test, using 5hr full capacity discharge test (100% DOD), battery cycle life

is not less than 300 times (equivalent to IEC60254 test life of 500 times)

Specifications: Designed according with the IEC60254-2014
