Power Tool Accessories 10X18650 Plastic Battery Case Storage Box Shell PCBA Charging Board For Makita 18V Hongsong 21V Machines

Feature:1. The BMS is for 5 series Li-ion batteries, mainly used for electric power tools It uses special IC for 5S lithium batteries as processor to detect real-time voltage,2. Charge and discharge current and ambient temperature of each battery Stable various protective functions for charging and discharging, such as overcharge protection over-discharge protection and short circuit protection.3. Low power consumption,the working current is about 25uA and quiescent current is about 6uA. Choosing the correct protection board and applying it appropriately is vital to the longevity your batteries4. Charge Voltage: 21V Single Cell Charge Voltage 4.25V Current Continuous Discharge Current 8-20A Overcharge Protection Overcharge Single Cell Detection Voltage 4.25VSpecifications:Name: Battery Plastic CaseType: 10 coresColor: as picture showMaterial: metal /plasticSuitable for MAKITA Power ToolNote: battery cell core is NOT INCLUDED in the kitPacking includes:1 set * battery shellNote:1. The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.2. Please allow slight manual measurement deviation for the data.PCB Specification:1. Built-in IC detects cell voltage current. And remember the number of uses!2.  Detection and protection battery: Overheat protection, overvoltage protection, undervoltage protection, overcurrent protection, overcharge protection.3. all the new series of for Makita achieve low voltage shutdown. Cooperate with many power tool factories!4. Color: Blue, or Green, or Red, etc. any color, PCB color and version number are different according to the actual latest inventory. 5. PCB design may change due to changes in the supply chain and processing technology. Please be kindly noted:If you have any objection to the following two items, please do not order !    (1).  PCB color may be any color according to our stock!   (2). PCB design may change   with the same function and performance guaranteed!   Once you place an order, you agree to the above two terms by default, and you are not allowed to submit disputes for the reasons of "different colors, design changes, wrong version of goods" and so on.Preparation before assembly:1. If a new core is used, please note: a. 18650 power lithium battery core must be selected,   b. A group of six cores must be equipped with resistance and capacitance to make their voltage the same.2. If the old battery is repaired, please test the voltage at both ends of each cell. If the voltage is different, please charge each cell to the same voltage value.Very important:Ensure that the voltage of each cell is the same before welding PCB.It can fill 10 pieces of 18650 li-ion batteries with LED battery status indicator.But this is only a shell, there is no battery inside.Packaging includes: As shown in the figure: No battery cell!!!Kindly Reminder (Very Important!!! ):1. The product is component without battery core, it is used to repair and assemble batteries pack, only for people who are familiar with battery performance and have practical experience in battery assembly.2. This product does not have after-sales service, it is just a set of components without batteries. You need to use your own 10 pieces of 18650 power lithium batteries to assemble a battery pack. We cannot guarantee that you will be able to successfully assemble it. Please purchase with caution! If you have any objections, please do not place an order.3. Manual measurement has errors, the size chart is for reference only, based on the physical item you received.4. Due to the difference between different monitors, the picture may not reflect the actual color of the item, based on the physical item you received.5. there are no batteries in the package !!!!!!6. If you need batteries, please don't place orders !7. If you don't have the knowledge of battery assembly, please don't place an order !
