Why can't smart lock lithium batteries use fast charging?
Recently, many friends in the smart lock sales industry have been asking: Why can't the lithium batteries in smart locks be fast-charged?
Most lithium batteries used in smart locks on the market have a charge cycle life of 250-300, with 4200mAh and 5000mAh as standard configurations. The charging port is 5V2A, although some early models were 5V1A.
Smart lock lithium batteries mainly consist of two parts: battery cells and protection boards. The smart lock market is currently extremely competitive, with most companies engaging in price wars and blatant cost-cutting. This has led to cost-cutting at every stage. Ultimately, the reason why smart lock lithium batteries cannot be fast-charged is due to cost considerations. The battery cells in the lithium batteries of major brands' smart locks do not support fast charging.
Therefore, it is recommended that consumers use a dedicated charger for smart lock lithium batteries or a 5V2A mobile phone charger.
