 How to choose the right BMS

Attention

Illustration

Mismatched BMS Consequences

Lithium
battery type

BMS type and lithium battery type must be in
one-to-one correspondence(Li-ion/Lifepo4)

1、BMS damaged,even bms and battery burn out
2、The battery cannot be fully charged and discharged

Number of battery pack
strings

BMS strings and battery strings must be in
one-to-one correspondence

BMS and battery burn out

Selection method
in experience

load maximum power÷(string number of battery×overdischarge voltage)×coefficient
Depending on the battery usage scenario, the coefficient value is also different
Please consult customer service for specific values


 Specialty

Bluetooth function:You can monitor battery data in real time by connecting to the APP


 Superiority

1、High-quality microelectronic components:precise and fast IC.Low resistance,high withstand voltage MOSFET.

2、Through the Bluetooth APP, the battery data is constantly monitored.

3、A variety of accessories,can easily control the data and modify the parameters.

4、A variety of communication modes,data monitoring,alarm backtracking,data reading, and upgrade can be easily realized

5、Thermal silica,accelerate the heat dissipation.Ensure the smooth operation of the battery.

6、Preset interface,buckle cable,make the connection more convenient.

 Balance cable connection

Preparation

Find the total positive and total negative of the battery pack.

Find B-/P- of BMS

Insert temperature probe (NTC) into the BMS

Welding

Note: When soldering, the balance cable cannot be inserted into the BMS

1、Connect the first string (black) of the balance cable to the total negative electrode of the battery, and the second string (red) to the positive

     electrode of the first string of batteries.The third string (red) is connected to the positive terminal of the second string of batteries,and so on,

     until the last string (red) is connected to the total positive terminal of the battery.Then check whether there is any cross in the balance cable

     or false welding.

2、After the balance cable is connected, do not insert the plug directly into the BMS.It is necessary to measure the voltage of the adjacent point

     on the back of the plug. (Regular voltage range: Li-ion: 3.0-4.15V/Lifepo4: 2.5-3.6V) After confirming that the voltage is correct, insert the plug.

3、Connect the B-(blue) of the BMS to the total negative of the battery.

Voltage measurement

measure whether the battery voltage(B+→B-)is consistent with the output voltage of the BMS(B+→P-).
If the two voltage values are equal, it means that the BMS is working normally.



 APP Download

Scan and download the Bluetooth APP

 BMS activation

Method ①

Press the activation button on the Bluetooth module

Method ②

Charge activation


 APP connection

1、When connecting to the APP, you need to turn on the positioning and Bluetooth of the mobile phone

2、Open the "SMARTBMS" APP, you can see the bluetooth serial number on the home page
(this serial number is the same as on the bluetooth module), click and enter to view the battery data.

3、Enter the battery capacity accurately, click "Setting", enter the password 123456,
refresh and the setting is successful

4、The SOC adopts the ampere-hour integration algorithm. When the battery capacity is set correctly,
after a complete charging and discharging process, the SOC is automatically calibrated


 Warning

1、BMS is a professional accessory. Misuse will cause damage. Please operate according to the instruction
manual or tutorial video.

2、BMS cannot be used in series or parallel

3、BMS does not support the use of reduced string numbers

4、BMS to work for a long time in an overloaded state is strictly forbidden

5、Lithium batteries need a dedicated lithium battery charger,
other chargers cannot be mixed to avoid BMS damage and other safety hazards

6、BMS disassembled by the user,No warranty policy

7、BMS is damaged due to unauthorized modification of parameters,No warranty policy

Great Value
I've been really happy with this watch. I like a bigger, "chunkier" watch, and I specifically did NOT want smart watch features. This is a great weekend and chores watch. I can beat it up, do work in it, and not worry about it. And surprisingly, it's been pretty bullet proof so far. Since I've worn a watch for almost my whole life, I barely notice when I have one on. And I am not precious about them at all. This watch has hit countless door frames, washed hundreds of dishes in hot water, scrapes against the wall, tools, yard equipment. It's been absolutely rock-steady and I haven't needed to adjust the time at all, other than for daylight savings. At the price, it's unbeatable.

Fantastic for the money
I use this watch at work, so about 40 hours a week I wear it. I work outside in a commonly rainy area, and it's not uncommon for the watch to get wet. I've had it for a couple months or so now, and it really works great! Honestly all of the complaints I have about it can be fixed solely by looking at the price. The viewing angle isn't fantastic - it's a $13 watch. It does lose a little bit of time (a second or two within a week, maybe) - it's a $13 watch. The band is a bit uncomfortable (though it does hold very well, and has lots of size options) - it's a $13 watch. Those are minor things. Here's the good stuff. -Super easy to read -Very easy to use and set -Multiple features -Is genuinely waterproof. I haven't held it underwater, or anything, but for what I would consider 'average' use, it is perfectly waterproof. -Has an adjustable band that doesn't fall off -Fairly tough. I don't treat mine very well and it's held up perfectly fine so far. -It's cheap!

Cheap Gshock replacement, good value
For $13 this is a steal. It's essentially a casio illuminator w larger bright dial, press once for 5 sec of light then goes dark. Date, time (12 and 24hr), stop watch. The basics, all I needed. A+ Edit: updated the waterproofing is non-existent. It's not even water resistant so treat accordingly don't bring into the shower. The face plastic cracked on me from moderate use, still legible and since I don't test it with water not an issue. The buttons are very sensitive so activities like lifting can cause the bottom left button to depress and switch to stopwatch, or engage the stopwatch. After over a year use I still rank this as a good value. It does the one thing I wish Casio would do is improve light illumination time. The buttons depress easier than Casio's which is a bonus imo, but can be aggravating to some. The water resistance doesn't exist so purchase accordingly.

Great watch, wristband wears out after a while. Uses a Skmei 1251 band.
Watch is reliable, doesn't drift in time too much, very efficient on battery, has gotten complimented on the look a few times and has a nice user interface. It's also great to be able to see the date without pressing any buttons. The band has fatigued and snapped after many months of putting on and taking off the watch, but If you'd like to find a replacement band, search for Skmei 1251 wristbands.
