BL1830 Li-ion Battery Case Charging Protection Circuit Board PCB LED Digital Indicator Box For Makita 18V 6.0Ah Housings Shell

For Makita 18V battery assembly case/parts

Prior Statement:

1. (DIY): This 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

Due to long-distance transportation, PCBs are usually in a low voltage protection state! Therefore, after assembly, please use a charger to charge and activate the PCB first!

Advantage:

1. Digital power display.

2. The motherboard has a BMS charge-discharge balance system.

3. Perfectly compatible with for Makita tools.

4. ABS flame retardant material, prevent fire, sturdy and durable.

5. The internal holes are aligned, and the parts will not be offset under high-frequency vibration.

6. Can DIY battery capacity.

No Original,100% Brand New, No Battery Cell !!!!!!

Note: The shipping list does not include batteries

Replacement Battery Codes:

194204-5 194205-3 194309-1 194230-4 BL1815 BL1830 BL1840 BL1850 BL1860 LXT400

Assembly effect

New design of power display

With LED indicate lights is percent capacity display,It can know the remaining power of the battery more accurately, avoid the battery being overused, and improve the battery life. You can also estimate the remaining working time through the remaining battery power.

Charge and discharge balance motherboard

The motherboard has a BMS system. When the battery is charged and discharged, each unit battery can be more coordinated and balanced. This can prolong battery life and make battery work more stable.

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 10 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.

Internal module fixing holes.

There are fixed holes between the modules inside the part, which can make each part precisely aligned, and no part deviation will occur in the case of high-frequency operating vibration.

18650 Battery Installation illustrate

Can installed: 10 PCS 18650 high-rate power batteries

Note: The 18650 unit battery discharge power multiple requires 5C \ 8C \ 10C.

(shipping list does not include 18650 battery pack)

Shell size

This dimension diagram is for reference only, measured manually with an error of less than 3cm, The size is based on the actual item received.

Very important:

Ensure that the voltage of each cell is the same before welding PCB.

Package include:

As the following picture: no battery cell

Special note:

   Please use a charger with the yellow communication interface shown in the figure below,

and do not use a simple charger like the one shown in the figure with " X "

Kindly reminder (Very important !!!!!!!):

The 6.0Ah label may differ from the one shown in the above figure. Don't buy if you mind

1. There are no batteries in the package !!!!!!

2. If you need batteries, please don't place orders !

3. If you don't have the knowledge of battery assembly, please don't place an order !
