BMS Smart Balance Li-Ion LTO 18650 Battery Ebike Protection Board 7S 8S 9S 10S 11S 12S 13S 14S 15S 16S ,Safety and Reliability

<ul><li>1. Advanced Battery Management System: Our BMS board is designed to provide advanced battery management for a wide range of battery types, including Li-Ion, , and LTO. With its build-in communication function, it allows for easy monitoring and control of battery parameters.</li><li>2. Reliable Performance and Safety: Equipped with a continuous discharging current of 90-320A and a balancing current of less than 100mA, our BMS board ensures stable and safe operation of your battery system. It also features single cell voltage detection with a range of 1V-5V and accuracy less than 5mV, ensuring accurate monitoring of battery status.</li><li>3. Easy Installation and Wiring: Our BMS board comes with clear wiring instructions, ensuring a hassle-free installation process. The wiring must be connected in sequence, starting from B- to B+, and the voltage of each battery string should be measured with a multimeter to ensure the correct line sequence.</li><li>4. Comprehensive Package: The package includes 1 BMS board, 2 temperature sensors, 1 active cable, and 1 battery cable, providing you with all the necessary components for a complete battery management solution.</li><li>5. Wide Compatibility and Applications: Our BMS board is compatible with battery strings ranging from 7S to 16S, making it suitable for a variety of applications, such as electric bikes, electric scooters, and energy storage systems. Whether you need to monitor and protect a small or large battery pack, our BMS board is the right choice for you.</li></ul>

Connect B- of BMS to the total nagative of BatteryBeforePluging the sampling cable into the BMS, Otherwise, the board will be burnt!FQA////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////1.What is the common port and separate port? what is the difference?We take 13S48V16A BMS as an example, common port 16A means your charge cathode and discharge cathode are connected in the same point end(our P-), charge cathode and discharge cathode are used in the common connection port, so the charge current and discharge current are the same 16A. while the separate port is separately connected by charge cathode (C-) and discharge cathode (P-), so the charge current and discharge current are different, discharge current 16A, charge current 8A.2.What is the balance function?The working principle and function are as followings, when your one cell voltage is up to alarm voltage(Li-ion up to 4.18V, Life Po4 up to (3.6V), then the cell Balance starts to work, balance resistance starts discharge with 35ma(when balance discharge starts to work, BMS will starts a little heat up, which is the normal reflection), the cell is in both charging and discharging status, and others which are not reached to alarm voltage(Li-ion 4.18V, Life Po4 3.6V) are only in charging status, no discharging, when the fast cell voltage is reached to alarm voltage(Li-ion 4.25V, Life Po4 3.75V)BMS starts off power protection, all the other cells are all in stop of charging, this process will enable your battery charging in balance current, and your battery voltage are in balance status, but when your cell voltage difference are in a big range, then balance can not be functioning well .3.The relationship between Battery capacity and BMS current?There is no direct relationship between Battery capacity and BMS current, big capacity doesn't mean a big battery, but rely on continue current, that is to say if your engine is powerful, your should choose high current of BMS, it is not relied on battery capacity.4. What type of charger should I choose?Lithium battery must choose specific charger, do not use Charger for Lead acid battery, for lead acid charger may have MOS with high pressure breakdown protection, which will not protect of BMS over charge.Life Po4 battery charger voltage=battery string No.X3.6V, while Li-ion battery charger voltage=Battery string No.X4.2V.5. What current BMS should I choose ?Take 10S36V as an example: what current BMS you choose is relied on your E-bicycle Motor power and current limitation of controller. eg., choose 16A for below 350W, 25A for below 500W, 35A for below 800W, 60A for Below 1000W, higher than 1200W are contact with our service specialist for suggestions, one in all, continuouscurrent shall be higher than current limitation in Controller.6. Whether my BMS damaged?
