Buy 3S 12V Lithium Battery 3.7V Power Protection Board with Temperature Protection Equalization Function Overcurrent Protection BMS Battery Protection Board good price

Bms is for battery use, different strings are not compatible.

E.g: 13S BMS, can not be used for 10S battery, can only be used on 13S battery.

 

Description:


Range: nominal voltage is 3.6V, 3.7V lithium battery (including 18650, 26650, polymer battery).

Function: Overcharge protection function, over discharge protection function, over current protection function, short circuit protection function, battery balance management function, temperature protection function.

Products: 7S or more adopts Zhongying integrated scheme circuit, and 7S or less adopts single-section cascade scheme circuit.

 

     
Temperature protection Zhongying Integrated Circuit Solution Three proof paint
The 3-7S is equipped with a mechanical temperature sensor, which can realize functions such as overcharge and discharge temperature protection, effectively improving the safety of battery use, and solving potential safety hazards caused by thermal runaway of batteries. The protection board responds accurately and sensitively, which has more advantages than traditional solution, saves circuit space, and the parameters can be adjusted according to customer’s customization to achieve the disconnection protection function. All circuits are coated with three anti-paints, which can effectively prevent electrostatic damage, prevent short circuits caused by humid environments, prevent air oxidation, and extend service life.
     
     
     
New Class A MOS Strong heat dissipation Send matching cable
The use of AVIC MOS can ensure product quality, low internal resistance during discharge, and low temperature rise during long-term discharge, without affecting the output of the battery, making the control safer. The heat sink is anodized, and the heat-conducting silica gel is cushioned to improve the heat dissipation efficiency. The structure is transparent and has a better temperature environment than the sealed type. Long-term discharge does not affect performance. White and red colors are sent randomly with the same effect.

Use the turn of operations:

1. The cable starts from the black thin wire connecting B-, the second wire (the thin red wire) is connected to the positive pole of the first battery, and the positive pole of each battery is connected in turn until the last red wire is connected to B+;

2. After connecting the cable, do not insert the plug directly into the BMS. Measure the voltage between each two adjacent metal terminals on the back of the plug. If the voltage of the terpolymer battery should be between 2.8V and 4.2V, the iron-lithium battery should be between 2.5V and 3.65V.

3. After correct wiring turn and voltage confirmation, insert the BMS socket.

4. The protective board B line (blue thick line) is connected to the negative pole of the battery pack.

5. After the wiring is completed, measure whether the total voltage of the battery pack and the total voltage passing through the BMS are equal. If they are different, check again according to the above wiring turn.

Tips:

The battery pack protection board, which is a semi-finished product of electronic products, is a wearing part in case of wrong use.

If you don’t understand how to use it, please read the manual carefully or ask the customer service. Any wrong use will burn out the front-end sampling resistor. We will not accept such disputes of customer damage. Please do not buy if you mind.

RECENT PRODUCT REVIEWS
  1. Its very good item for me, usually I am using this for charging my power bank (10000mah). Very good.

  2. Excellent android box

    I bought one for us. And to be honest I was VERY SCEPTICAL. But once installed the sky is the limit on what you can do. Our kids are grown with their own children and even the grandchildren know how to operate it and love the video options. So we decided to get them their own and not to brag but mom and dads gift were the bomb. Even the grandchildren were excited 

  3. A+ If you use the right cup!

    After having it for a few days I love it! I tried it with different cups and mugs and you’ll want to use the a mug with a flat base to really spread the heat. I pre heat my mug while my coffee brews and it will stay hot as long as you’d like. I found the default high heat setting worked best for me. It’s not to expensive and makes a great gift. I got mine in black and it looks great on my desk at work.

  4. Yes, it works!

    This thing really works. If you are reading a review that says it doesn’t then they r either not using it correctly or using the wrong product. I did not get paid to use this product or my personal opinion like others. I didn’t want to spend all the extra money on a fancy brand name with the same results. My pics will speak for themselves. 

  5. Perfect nothing to say and accurate data super
    Thanks to seller send fast

  6. Lightly box is pressed in brightness, but writing data is no problem four yo ~

  7. Arrival a few days before the scheduled date, very satisfied. Well packaged, received intact and functional, perfect for sketches, simple design but good for the price. Comes with an anti-loss strap, and the pen easy to store.

  8. I arrived a week earlier than planned, I loved it coming with the battery included, very good product

  9. It didn’t take long to get there, all ok
