72V 3A Ebike Smart Charger

This is the newest model of Ebike Charger 72V 3A for electric fat bike and electric enduro bike with a pretty good quality and performance.

Main Features:
84V 3 Amps smart charger for li-ion battery, operates AC 100-240v 50/60Hz

The items of upgrading and improvement:
1. 40% smaller dimension (less transportation fee), easy for carrying of the consumers;
2. Eventhough we reduced 40% of the dimension, but thanks to our efficiency increased from 87% to 92%, the working temperature is 10℃ lower; with higher efficiency, it's better for environment and saving energy;
3. Add over-temperature protection, when environmental temperature is too hot (>40°), charger will stop working; if the temperature reduced, the charger will work again automaticlly;
4. Add timing protection, after 10h charging, if battery is still not full (perhaps battery has problem), the charger will stop working;
5. Add BMS protection, now all the chargers in the market has the inrush current once the charger connected to battery, the peak current can reach to 50-70A, and this huge current perhaps will damage the BMS (like the fuse), then the new charger have no this peak current because of new techology inside.
