Model No : S4 PLUS (V3.0)
S4 plus is currently upgraded to V3.0. Performance has been improved.
The Vapcell S4 Plus is a Super,Revolutionary,Intelligent charger ,3A each slot ,12A in
total charging current with almost all cylindrical rechargeable batteries,such as 16340,
10440, 14500, 16340, 18500, 18650, 26650, 21700 20700,even button top or PCB
21700,20700, which eliminate to own several chargers.
The S4 Plus automatically detects and charging Li-ion,Ni-Mh and Ni-Cd batteries,
Intelligent charging circuit selects the optimal charging mod (CC,CV and -dV/dt) for a
given battery and each slot independently charge.
The charger can measure the internal resistance (DC IR) of the battery intelligently, and
automatically distribute the appropriate charging current or discharge current according
to the internal resistance of the battery.
S4 plus charger have Manual and Auto mode selection for charging and discharging
currents.
S4 plus have five mode: Charge ,Discharge,Cap test( Capacity Test),Storage，Repair.
The capacity of batteries can be accurately measured by Discharge mode and Cap test
mode, and li-ion batteries and Ni-Mh and Ni-Cd batteries can be repaired by Repair
mode.If li-ion batteries want to be stored, users can use storage mode to extend battery
life
Furthermore,LCD display show voltage ,capacity, temperature, internal resistance ,
charging time and percentage of capacity clearly.
For better use of the charger, please read the instructions.

Page 2: Function Description
1. Function Description: Manual&Auto button There's a button on the right side of the charger. Manual selection of charging and discharging current or automatic intelligent distribution of charging and discharging current 1.1.1 Manual button... - Page 3 The advantage of manual mode is that the user can choose the ideal charging current or discharge current. When the battery starts charging or discharging , the default current is 500mA and flashes continuously, indicate the user to choose the current option you want For specific current parameters, please refer to the charger parameter table.
- Page 4 There are three steps in this mode: Charge-Discharge-Charge The charger full charges the battery first. then discharge at a constant current to the cut-off voltage, the charger shows the capacity of the battery.then the charger fully charge the battery again .but the charging capacity is not displayed. 1.2.4 Storage In order to increase the cycle life of li-ion batteries, the new version has added storage mode.

Page 5: Operation
In the Auto mode, the system will measure the internal resistance of the battery and automatically distribute the current. S4 plus charger have a lot of current option, if you want to know more, please refer to the parameter table. - Page 6 requires manual selection of current, while Auto mode does not. Now let's explain the following operations in manual mode. 2.3 If the battery is reversed, “ Err” will be prompted in LCD screen. Users put the battery correctly into the charger.assuming that it is placed in the second slot, CH2 characters will appear on the display screen.

again, reciprocating. This display indicates that the battery is charging. At this time, the display screen will display all the data of the second slot.voltage(V) ,capacity(mAh,Wh), temperature(℃), internal resistance（ ）, time （00:00）,current(mA) and percentage mΩ of capacity clearly（%）.If the battery is discharging, the cylindrical grid will flicker and decrease. - Page 8 Capacity(mAh)= Current (mA)* Time (Hour) So tell us that in order to use the S4 PLUS charger to measure the battery capacity more accurately, please measure room temperature around 24 degrees. If the temperature is too low, the battery capacity will be greatly reduced.Then choose the appropriate battery...
- Page 9 the battery in real time.If the battery temperature is too high, we will reduce the charging current intelligently,ensure safety.To increase temperature sensitivity, a milky white thermal conductive adhesive is added below the circular metal. If a small amount of colloid seeps out, please remove it with a cloth. 1.

Page 11: Warranty Service
Be sure to know LiFePO4 batteries(3.2V),Non-rechargeable batteries, rechargeable alkaline batteries (RAM), lead acid batteries must not be charged with S4 plus charger. There is danger of explosion! Please read these instructions before use; pay attention to the recommended charging current, never choose the wrong charging current. - Page 12 2. Incorrect operation results in damage to the products(such as refitting the battery, putting it into a non-rechargeable battery, or violating the warning) 3. Battery Leakage causes product damage For the Latest information on vapcell batteries and services, please contact a local vapcell distributor or send an email to admin@szfyte.com 6.
