Haibao battery is a good one in the deep cycle life test of domestic electric bicycle battery. In the early years, it was equipped with more vehicles, how modest, Bridgestone and Yamaha. The key problem is still on the charger. I charge and discharge three groups of Haibao batteries 100%, and the life span is nearly 600 times.

Of course, I didn't use constant voltage current limiting or variable current charger mode, but used "pseudo-constant voltage" pulse charging with temperature control. Constant voltage and current limiting charging has also been used for more than 200 times, and the battery of Shenyang Panasonic is better than Haibao. But the charging voltage is different, and the batteries of other manufacturers are not as good as those of Haibao.

There are also some "wild" manufacturers whose batteries are really poor. They excessively pursue the early battery capacity, and the battery capacity drops too fast, which is suspected of fooling users (fooling electric bicycle manufacturers). In addition, when you drive18km every day, you discharge about 50%. On the basis of constant voltage and current limiting charging, Haibao battery should reach 500 ~ 600 cycles, and the calculated value is similar to your actual use.

Proper shallow cycling can prolong battery life, so users must be reminded that daily charging can prolong battery life. Haibao battery released a new technology product graphene black gold king in Tianjin. At the press conference, Shen Weixin, chairman of Haibao, said that Nidhogg has unique advantages in structure, and graphene, the king of new materials, has anti-aging effect.
