Precautions for use

1. The initial battery charge is inaccurate. Please fully charge and discharge from 0 to 100 for at least 3 cycles! Please discharge the battery pack first and then fully charge it if it cannot be discharged! Due to the series connection of the battery pack, there is a voltage difference between each pair of batteries, which requires repeated and long-term balancing of the power to be accurate. Therefore, during the charging process, there is no need to worry about how much power is displayed on the battery box. As long as it reaches 100, it can be charged for more than 5 hours to ensure that the passive balancing chip can work every time, reducing the difference between battery packs. At the same time, the chip also records the actual capacity data of the battery pack multiple times so that the power level can be more accurate.

2. The battery box is detachable! Please be sure to use 8 3.7V flat head unprotected 18650 (18 * 65mm) lithium batteries with the same voltage, capacity, internal resistance, and multiplication rate. You must bring your own multimeter to test the voltage of each battery, and it cannot be lower than 3V. It is recommended to use ternary lithium power batteries with a voltage of 3.5V or higher. To ensure stable output, please note that if the charging phone experiences power failure after charging for a while, repeatedly intermittent, it indicates that the battery is not strong enough, the internal resistance is too high, and the magnification is not up to standard. Please replace the battery!

3. Supports 5V charging and discharging at the same time, but multiple ports can only output 5V at the same time

4. Do not damage the battery! (The outer skin must not be exposed and must be insulated) Do not install it in reverse (please pay attention to the positive and negative directions), otherwise it will short-circuit and damage the product! Attention: Burning springs and smoking are only battery and operational issues, please be aware of non product issues!

Summarize the performance of the battery pack and the reasons for related usage issues!

After assembly, frequent use of a charger to charge and activate the power bank indicates significant differences between battery packs. Please replace the batteries

2. If the battery cannot reach 0 after multiple discharges and has been charged for more than 20 hours, it indicates that the battery rate is not up to standard. Please rule out the problem with the battery

3. If the battery pack is not durable and has been charged multiple times for more than 20 hours, it indicates that the actual capacity of the battery pack is not high, or the rate is insufficient, resulting in a large voltage drop and premature power failure

4. If the phone loses power after charging for a few minutes, or if more than 50% of the battery cannot be discharged, it indicates that the battery performance is seriously poor. Please replace the battery

5. If the battery heats up during charging and discharging, it indicates that the internal resistance of the battery is too high and the rate is not up to standard. Please replace the battery

6. It is normal for the charging and discharging motherboard to heat up. The higher the current, the greater the power, and the greater the heat generation. If there is temperature control protection, it will limit the current and cool down to a certain extent, so there is no need to pay attention to it!

7. It is normal for the charging and discharging motherboard to produce a current sound, as this solution adapts the voltage range from 3V to 20V and has a wide range, so there is no need to pay attention to it

After discharging, the rebound voltage of a single battery is 3.3V, which is within the normal range. This is because the spring has a voltage drop and the contact surface also generates contact resistance. The larger the current, the higher the resistance value. If it exceeds 3.4V, please clean the battery thoroughly and check the actual discharge performance of the battery pack again

Caution:
The product only allows the installation of 21700 flat batteries, voltage between 3.5V-4.2V, more than two years of batteries, the number of cycles more than 300 times the battery, basically not durable, found that charging intermittently can only be used for a few minutes, more than ten minutes, half the time the phone can not be charged, these are batteries do not work, the multiplication rate has been substandard performance caused by the problem of poor performance. In addition, the product does not support modification, welding. If you use the battery does not meet the requirements are not responsible for after-sales. The motherboard is retrofitted with an anti-installation chip, installing the reverse does not burn the motherboard, but due to the spring shrapnel is one piece, the battery broken skin, battery short-circuit, a positive and a negative, series connection will cause the burn spring, but re-installed correctly, the motherboard is always able to use normally, will not burn.
