240W 13s 18650 Lithium Ion Battery Chargers 48v 54.6v 4a 5a Aluminum Shell Electric Scooter

240W 13s 48v 54.6v 4a 5a aluminum shell electric scooter bike 18650 lithium li ion battery charger

Main Features:

1. Compact & Delicate & Energy Saving -- Switch Mode Tech

Small and light, as we adopt the switch mode technology or called Switching Power Supply technology. Compared withtraditional Linear Power technology, ours is more energy saving as more than 85% electric energy is transferred to battery chemical energy duringcharging process while traditional tech can onlytransfer 40%.The tech is suitable for all types of lead acid batteries (wet,flooded, maintenance free, VRLA, AGL,AGM, GEL, etc)as well as lithium, lipo batteries.

2. Automatic-- MCU control

MCU system is applied. The whole charging process is monitored. Multi-stage charging automatically proceeds. No need for manual interference.

Automatically stops charging when the battery is full. You can leave the charger connected to the battery infinitelywithout the risk of overcharging. Once the battery is full, the charger monitors the battery’s voltage intermittently. If battery’s capacity decreases or voltage drops under set level, the charger can start again to charge battery to its full.

3. Multi-stage charging-- full charge but never overcharge& save battery & save energy

Max 8 stage: pre-charging, soft charging, main charging (bulk charging), secondary charging, high constant voltage charging (absorption charging), 3-minute test, Float charging, End maintenance charging.

This way can well transfer electricity into battery according to battery’s absorption ability. On the one hand, save energy; on the other hand, protect battery from over-charging, therefore less gassing less temperature rising. Float charging and End maintenance charging also help protect battery and prolong its lifetime.

4. Digital display:

It can show the charging process, the user can know when it is ready for use.

5. More Protection

Tester function: If battery has abnormal state, the charger will display error code and reminds User to check battery whether it is good or bad.

Polarity Protection: Prevents the output leads from sparking due to accidental reverseconnection or short circuit.

Overcharge and Over-voltage Protection: never worry about overcharging or over-voltage as charger automaticallystops when battery reaches set voltage or current.

6. Customization

We can change parameter to meet different applications. Make charger specifically for your battery.

7. CE and RoHS

We have CE and RoHScertification.

8. Warranty

We design our charger for 2 years and offer one-year warranty.
