Technical points

In order to use this charger well, please read the following technical knowledge

Measure the internal resistance of batteries

The Auto mode of the charger distributes the appropriate current by measuring the internal resistance(DC IR).so it is necessary to measure more precise values. Please keep the positive and negative connectors of the charger clean and free of grease stain, and the positive and negative electrodes of the battery clean.And check the spring of each slot to ensure that the battery and charger are in good contact.

Measure battery capacity

Industry-approved test capacity method, room temperature of about 24 ℃, charge battery with li-ion 4.20V, and then discharges at a constant current of 0.2C to 2.5V. Please remember to keep a record of discharging time.
In this way, the capacity mAh of the battery is obtained by multiplying the discharge current by the discharge time.
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 discharge current, about 0.2C rate. Please do not use the capacity shown during charging as the battery capacity, because many batteries are out of power from the device, and the battery voltage is about 3.0-3.4V.,the battery still have power.

In order to measure discharge capacity more accurately, we set the discharge cut-off voltage of the Li-ion battery at 2.5V. There are a lot of high capacity 18650,21700 batteries, The discharge mode is in the range of 3.0V-2.5V, and there are still about  50-200mAh capacity.

Current Selection

This charger has a high charge current 3A and a discharge current 1A, To ensure safety, please refer to the battery specification and select the appropriate charge and discharge currents in Manual mode. If the current is too high, the battery may become very hot and explode! In Auto mode, if the internal resistance of measurement is relatively large due to poor contact or oil stain, the allocated current will be relatively small. If you want to increase the charging current, press the current button for at least 2 seconds. The current of the display screen will flicker continuously, then pressing the current button can change the current. CC, CV mode is used for charging li-ion battery in the charger If li-oon battery voltage before charging is relatively high, such as 4.12V, put into the charger at Auto mode, even if the internal resistance is very low, very small charging current will be allocated,at present, it is in the CV stage of charging, that is, it will maintain a constant voltage of the battery, and the current will gradually decrease and cut of,so don’t misunderstand that the charger needs maintenance

Charger Temperature Control

Temperature sensors are installed in each slot of the charger to monitor the temperature of 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.

Vapcell-S4-PLUS-\(V3.0\)-Fast-Charger-FIG7

  1. Temperature is higher than 65 ℃. If the charging current is higher than 1500 mA(excluding 1500 mA), it will be reduced to 2 levels, for example, your current charge current is 3000mA, it will be automatically charged at 2000mA.
  2. The temperature of the slot is more than 70 ℃. If the charge current is more than 500 mA (excluding 500 mA), the charging current will be forced to drop to 500 mA.

Battery charging current level:
250mA, 500mA, 1000mA, 1500mA, 2000mA, 2500mA, 3000mA

Re-change MODE or CURRENT

If the battery is charging or discharging, other modes can be changed by pressing the MODE button for 2 seconds, and the current can be changed immediately after changing the mode, but the data on the previous display will disappear. Please be careful.

When the charger works normally, if it is in automatic mode, press and hold the current button for more than 2 seconds to forcibly change the current. When grease or other factors affect the measurement of battery internal resistance, we can forcibly select the appropriate charging current of the battery. In manual mode, press and hold the current button, and the current will not change.

Extending the Service Life of Charger

This is an intelligent multi-function charger.
In order to obtain a longer service life, please keep operating in dry environment in the door, and have enough space to emit heat. In order to prolong the service life, please try not to discharge/charge four slots at full load for a long time. Because full-load operation will lead to the increase of charger temperature, long-term high temperature of charger will accelerate the aging of charger parts. Be kind to it and continue to serve you.
