How to comfirm your charger Charge Voltage(Constant Voltage: CV)?

Lithium Ion Battery = 4.2V x the number of cells in series("S"↓);

LiFePO4 Battery = 3.65V x the number of cells in series("S"↓);

Lead Acid Battery = 14.7 x the number of cells(12V/cell) in series("S"↓).

Customized 1200W Sealed Waterproof Charger with PFC 1200 Watts Aluminum Alloy Shell Smart Charger 47.45V 51.1V 54.75V 57.6V 58.4V 20A LEP LiFePO4 Battery Pack Charger

Please notice:

1. Cut-off current: Lead Acid 20% CC, Li-ion/LiFePO4 5% CC; Protection: over-voltage, over-current, short circuit, reverse polarity; PWM chip intelligent control, smart cooling improve efficiency to 85% in full load to save more power and extend battery cycle; CC-CV-Trickle or float charge can meet more different batteries' requirement.

2. Each of our chargers only can charge for one kind of batteries, because different battery, the charging curve is different. For example, if you order Lead Acid battery charger, it will only be suitable for Lead Acid battery not for Lithium Ion or LiFePO4 battery.

3. If you choose "EU", it means the charger is only suitable for Europe(200-264V/AC), and if "US", it means USA(100-132V/AC), please take it seriously! Both is not universal! Unless the charger is 100-240V/AC input.

4. Because all chargers are custom-made according to your demands, it is impossible to change the specifications to resell, so we do not accept to cancel the order over 24 hours after the order is paid. Please know it and then to purchase. Thanks for your understanding and support!

5. The selected connector must match your current, otherwise it cannot be used. If you can't confirm it, please contact us before ordering to confirm the matching connector, thank you.

If you have any question about the products, please contact us, thank you！
