Top Details Compare Questions Reviews SEE LESS Description The 4S 14.8V 20A Lithium battery Protection Board comes with over-charge, over-discharge, over-current and short circuit protection, for a variety of various shapes 3.7V lithium-Ion batteries. HXYP-4S-BMD1 is Small size square shape board under which four 18650 cells can be packed suitable for many requirements of high integration, low cost of the occasion, to meet a wide range of performance requirements to ensure that the battery pack is absolutely safe and reliable. This BMS (Battery Management System) ??? a battery management system that is designed to monitor the status of batteries, control the battery charge/discharge process, etc. Four 18650 batteries can be connected simultaneously to the HX-4S-BMD1 module. The features of this charge controller are protection against short circuit (short circuit) and protection against over-discharge (overcharge). Also, a feature of the module is to turn off the power supply for the batteries when the maximum capacity of at least one battery is reached. The maximum operating current of this BMS controller is 20 A, and the quiescent current reaches up to 10 ??A. The battery charge is switched off when the voltage reaches 4.25 ??? 4.35 V, and the discharge when the voltage drops to 2.3 ??? 3.0 V. If the maximum permissible value of the supply voltage is exceeded, the charge controller activates the ???protection??? mode. In order to restore the module, it is necessary to re-apply voltage to the input of the BMS board or wait a while until the charge controller automatically disables protection. 4S 14.8V 20A Lithium battery Protection Board connection Diagram BMS solder instruction: B+ connected battery positive; B1 the connect point between battery 1 and battery 2; B2 connect the point between battery2 and battery 3; B3 Connect the point between battery 3 and battery 4; B- connect to battery negative end; P- + connection charge / discharge positive; P- connection charge / discharge negative; Small size designed for a four-cell battery pack.

15W Mini Soldering Iron For Home, School, College, Small Electronics & Mobile Repairing Work This soldering iron is made of iron plated tip and stainless steel, ensures the quality of the products and the properties of the stability and reliability. You don't need a soldering station, just plug and it will work. Working Process - 1. Clean the parts to be joined. 2. Heat parts , not solder to be joined. 3. Apply flux-core solder to heated parts, not the soldering tip and heat it till solder melts and flows freely. Cautions 1. When the soldering iron is plugged in for the first time, there will come out a smoke from the tip end. 2. The smoke will stop in a short while and a smoke would never come out again. 3. Use soldering stand and other aids to avoid burnt fingers. 4. Don't pull the soldering iron tip outward and use it in that way, which will shorten the heating element life. 5. Don't apply too much solder unnecessarily. 6. Handle the heated soldering iron with extreme care as the high temperature of the can cause fires or painful burns. 7. Keep away from Children & Minors. 8. Never File the specially-plated tip.
