Spare parts are common to 18650 and 21700.The spare parts can only be sold at the current price. Due to the complex installation of this model, we need to provide technical support and after-sales service. If the quantity is large, there can be a lot of discounts.

Product Description

1. The newly upgraded 200w high-power mobile power supply. This product is upgraded from the old model with a new solution. The old 200w is one way IP6559 and one way sc8812. However, due to the compatibility problem of sc8812, some chargers can not be recognized sometimes. After the new model is upgraded, the sc8812 is replaced with IP2368. The compatibility of products has been greatly improved. At the same time, a major upgrade has been made to the coulomb meter. The old model does not have a coulomb meter. It uses a direct reading voltage and has no percentage. And it is not complete after shutdown, and it consumes a lot of power. In the new model, we use bq4050 coulomb meter, which can accurately count the electricity. At the same time, the voltage of each section is more accurate, and there will be no frequent refresh changes.

2.1.54 inch wide angle IPS color screen displays various data in real time. The product adopts AT32F403ACG master control, and the screen is 1.54 inch wide angle ips color screen. The system is stable and there is almost no possibility of crash. The product can be output and input to automatically wake up, or can be manually wakened by pressing the key.

3. The solderless structure battery box is more convenient to install the battery. The battery assembly does not need to be welded and does not damage the battery. It only needs a few screws to fix it. It is simple and convenient. It can also be replaced quickly after damage.

Note to purchase: only 21700 batteries with diameter less than 21.5mm can be installed for spare parts. For example, Samsung, lg, Tesla, etc. Some domestic batteries are too large in diameter to be installed. If they are hard installed, they may cause damage such as skin breakage and short circuit. Such damage is of little repair value. Please use high-quality 21700 batteries!200w, the detail page is illustrated with the following figure: the bulk type is solderless assembly battery, which is mainly for the convenience of customers without spot welding machine. The contact resistance of solder contact may be relatively high when using the contact of shrapnel. If the battery is not balanced or the installation voltage and internal resistance of the battery are not consistent, or the installation is not in place, it will cause the situation of voltage inconsistency on the figure. Our finished products are installed by welding the nickel strip of the battery, the contact resistance can be almost ignored, and the battery voltage can be basically consistent. You can also contact us to send welding parts, but there is a great possibility that they will be damaged due to poor assembly. Such parts also have no after-sales service.

Note: For the DIY kit without battery, the battery display on the display screen is 5000mah by default, so please use 5000mah battery during installation, and other capacity needs to be modified, which is $5 per time. In addition, the coulomb meter needs to be learned, and it needs to be repeated several times before it can display accurately.

Because of the DIY kit, the customer did not understand and the installation was not standardized, resulting in losses, and then opened the dispute for refund. We have suffered losses, so if we need to buy a kit, we need to ensure that we do not apply for a refund. We will reduce the price to let you buy it. At the same time, we will be responsible for after-sales service throughout the process and answer questions about installation and use.

The product has a capacity of up to 40000 mah, and most mobile phones have a capacity of around 4000 mah, with a capacity difference of 10 times. Therefore, the charging time of the charger for the charging bank will also be several times longer than that of the mobile phone. Some inferior chargers cannot work at full load for a long time, which can easily lead to damage to the charging head. For example, when the product is fully discharged and fully charged, it requires a charging head with a full power of 100w to output for 1.5 hours. If the charging head does not have temperature protection, it is extremely easy to cause damage. As long as the product can be used normally after changing the charger, there will be no quality issues with the product. Contact the manufacturer to resolve the charging head issue on your own.

Calibration steps for coulomb meters: First, fully charge to less than 3W input power, then discharge at medium power (within 50W, recommended within 30W) and place it on a protective board for protection, completing the learning of capacity calibration once

Note:1: It is normal for the battery voltage display to be unbalanced during charging and discharging, and it can be restored to normal after unplugging the plug

2: When receiving the discharge for the first time, turning on% may indicate abnormal display. For example, if the battery is charged to 80%, it cannot be charged. At this time, depending on the total battery voltage, the voltage reaches 16.8V and the maximum voltage has been reached. If you want the capacity display to be normal, you need to follow the capacity learning steps on the details page to operate
