Electric Bike Battery Charger 10S – 2A 42V LiPo/Li-Ion DC 2.1/5.5
Electric Bike Battery Charger 10S – 2A 42V LiPo/Li-Ion DC 2.1/5.5
The 42V 2A electric bike battery charger is designed for charging lithium-ion (Li-Ion) and lithium-polymer (LiPo) batteries in a 10S configuration (36V nominal voltage). Thanks to its automatic operation, it provides convenient and maintenance-free charging for batteries used in electric bicycles, electric scooters, and other devices powered by lithium batteries.
The Li-Ion 10S 42V 2A battery charger features a DC 2.1/5.5 mm connector, allowing easy connection to compatible battery packs. When used with a suitable Battery Management System (BMS), it provides a practical and convenient solution for everyday battery charging.
Automatic Electric Bike Battery Charger
The 36V (42V) electric bike charger requires no additional configuration and is ready to use once connected to a compatible battery and mains power supply.
The charging process is fully automatic. Once the battery reaches full charge, the charger stops charging and switches to standby mode.
Thanks to its compact design, lightweight construction, and simple operation, the 42V 2A electric bicycle battery charger is ideal for everyday use or as a spare charger.

Notes and Tips:
Correctly selected power of the charger is important for the safety, life and failure-free operation of your battery. It is assumed that a properly selected charger should charge a fully discharged battery in the optimal time for about 6-9 hours, i.e. by connecting the charger at 9:00 p.m., it will be charged by 6:00 a.m. By choosing the wrong charger power (too strong charger in relation to the battery capacity), you can shorten the life of your battery, cause its failure during use and reduce the effectiveness of BMS balancing, which in general will not be worth it if the battery is charged at 2 o'clock: 00 at night
The charger cannot charge the batteries by itself. For proper operation, it requires a BMS or external balancers to control and equalize the voltages of individual cells. Charger and BMS voltage must match.
Connecting the charger
Always connect the charger in the following order:
1. 230V cable to the socket.
2. Power cord for charging socket.
Reverse connection will damage the charger which is not covered by the warranty.
