Many customer inquiry me the charger after they buy the lifepo4(LFP)Battery from me, but i find they use the charger of  Lead acid battery on lithium ion battery  , so i introduce basic information about the charger

1  Whats the charger 

A battery charger is a device that converts AC mains power into DC power compatible with the battery. It must  match  the battery type, voltage, current, and protocol; otherwise, it may damage the battery or cause a fire if you use them wrong .

2  Battery Type Selection for charger

        1）firslty Ternary Lithium Battery (Li-ion/Li-poly, 3.7V/series): This is for Mobile phones/electric vehicles/tools; it need constant current/constant voltage + BMS; cutoff 4.2V/series; overcharge and overheat protection.

        2）Secondly Lithium Iron Phosphate (LiFePO4, 3.2V/series): This is for Energy storage/electric vehicles;  it will dedicate charging curve; cutoff 3.65V/series; must have BMS.

Above for the Lithium Iron Phosphate Charger

         3）Thirdly Lead Acid (12V/24V):   It is for  Automotive/batteries; constant current → constant voltage → float charging;  when we  fully charge the 12v  approximately 14.4V; anti-sulfation.

       3 by  power and speed to choose the charger 

 As below 

          1) Firstly  Slow Charging (5–10W): 5V/1A–2A; Safe and does not damage the battery, suitable for long-term float charging.

         2) Secondly  Fast Charging (18–120W): PD/QC/SCP/UFCS; 0–80% fast charging, 80–100% slow;  it  will must match protocol 

   4 the real case . pls read the links for my previous blog as below :

     There  is  more  details about the charger ,because it is used on the  Electronic tricycle , It will be more complicated
