Lithium-ion bicycle battery selection and maintenance

Lithium-ion bicycle battery selection and maintenance

Comparison of different battery capacities
Currently, there are three specifications of lithium battery cells on the market: 2000ma, 2500ma, and 2600ma.
1. Compared with 2000ma, 2000ma can be made of manganese-doped materials, which will be cheaper and have lower performance. 2500ma and 2600ma can only be made of pure ternary materials.
2. Compared with the 2500, the advantage of the 2600 is that it has a larger capacity and there is not much difference in process.
3. Pure ternary lithium battery, also known as "ternary lithium polymer", refers to a lithium battery using nickel cobalt manganate or nickel cobalt aluminate as the positive electrode material. Due to its smaller size, higher capacity density, and low temperature resistance, ternary lithium batteries have absolute advantages over lithium iron phosphate, lithium manganate or lithium titanate.

Battery maintenance
1. Use a special charger that matches the battery specifications;
2. Maintain good natural ventilation during the charging process. If the ambient temperature is too high, spontaneous combustion may occur easily. If you find that the battery is deformed or abnormally hot, please stop using it immediately.
3. It is forbidden to place lithium batteries near heat sources, fire sources, flammable and explosive gases or liquids, otherwise it will easily cause the battery to leak, heat, smoke, catch fire and explode.
4. When the lithium battery is stored unused for a long time (more than a month), it is recommended to charge it to 40%-60%, and the battery needs to be charged for 1-2 hours every month.
5. It is not recommended to charge in the living room. When charging, please make sure there are no flammable and explosive objects near the battery. The charging time should not exceed 2 hours after full charge.
6. Do not charge immediately after riding for a long time. The vehicle needs to stand for 2 hours before charging.
7. Attention when riding in winter! After riding the vehicle outdoors, please do not charge it immediately due to the difference in indoor temperature. It must be left alone for 2 hours before charging.
