QINIZX5S 18V 21V 1.2A Li-ion Lipo Lifepo4 LFP Battery Active Equalizer BMS Balancer Inductive Balance Lithium Battery Energy Transfer Board (5S)
Main highlights- Voltage balance accuracy: 30mV (typical value) between adjacent voltages; Balance current: 0.1V
0.2V, balanced current 1.0A (max 1.2A); Under-voltage protection dormant voltage: The adjacent voltage difference is less than 0.03V and enters dormant state, Sleep current 10uA. - Tips: The equalization board is not a BMS protection board, it is an auxiliary to the protection board, so no matter how bad the battery you use to test, it can be used, But it has no overvoltage/overdischarge protection function. Overvoltage/overdischarge is the function of the BMS protection board. If voltage protection is required, it is best to use it in parallel with the BMS protection board.
- NOTE: Only can use for 5s battery-packs, and Not recommended to use poor quality battery pack to test. The indicator light will flash and report an error. Before connecting the equalization board, be sure to check whether each battery is wired correctly (Measure whether the voltage of each battery string is correct), and do a good job of insulation. otherwise it will short-circuit and burn the board.
- Balance method: Detect that the voltage difference between adjacent batteries is greater than 0.1V to trigger the start of equalization, and the adjacent battery voltage difference is less than 0.03V to stop working. (Tips: The inductance equalization board needs to be charged/discharged many times before the voltage equalization can achieve a better effect.)
- Applicable battery type: NCM(Li-ion)/LFP, NOT support LTO; Single voltage working range: 3.0V-4.2V; Suggested battery capacity: below 30AH, If more than 30AH, pls search Capacitor Faster Whole Group Balancer " B096NLHXPF " to purchase.PCB size about: 2.08x2.04x0.31inch; Indicator light: LED on, balance in progress; LED off, balance ends; LED flashing: battery drop string indicator/circuit failure.

ACEIRMCACEIRMC 2pcs BMS 5S 21V 18650 Li-ion Lithium Battery Protection Circuit Charging Board Module PCM Polymer Lipo Cell PCB (5S BMS 25A 21V)
Main highlights- This protection board adopts mature protection circuit, special IC, imported high current ultra low internal resistance MOS (single MOS internal resistance as low as 3 milliohms), and has perfect and stable charging and discharging protection functions.
- Single Cell overcharge protect voltage: 4.23 - 4.28V;Single Cell overcharge rotect recover voltage: 4.08 - 4.18;Overcharge protect delay: 0.5 - 1.5S;Single Cell over-discharge protect voltage: 2.72 - 2.88V;Single Cell over-discharge rotect recover voltage: 2.9 - 3.1V;
- Overcharge protect current: 60A;Over-discharge protect current: 60A;Over-discharge protectdelay: 0.5 - 1.5S;
- Charging voltage : 12.6V for 3S BMS board,16.8V for 4S BMS board,21V for 5S BMS board.
- Before installing the protection board, the battery must be matched well (the voltage difference between each battery is not higher than 0.05V, the internal resistance is not more than 5mΩ, the difference of the capacitance is less than 30mAh), the better the battery consistency, the longer the battery life, and the best performance of the protection board.

Be In Your MindBe In Your Mind 2Pcs 3.7V 20A 5S Polymer Lithium Battery Protection Board 18650 Lithium Battery BMS PCM Battery Protection Board 55x18mm Red
Main highlights- When connecting 5 sets of batteries in series, please ensure that the voltage of each set of batteries is the same. If they are different, please charge each set of batteries separately before using them in series. During the discharge test, the battery with the fastest voltage drop is the bad battery. Don't mix good batteries with bad batteries. The closer the capacity and internal resistance of the battery pack are, the better.
- This protection board is a power-type high-current lithium battery protection board. It has a small size and high current, and can be used in high-current applications such as power tools and model aircraft.
- Lithium batteries must be charged with a special charger for lithium batteries. Do not use a lead-acid battery charger. Lead-acid charging may cause high voltage to breakdown the MOS tube of the protective board, causing the protective board to be overcharged and not protected.
- Before installing the protection board, the batteries must be well matched (the voltage difference of each battery is no more than 0.05V, the internal resistance difference is no more than 5m, and the capacity difference is less than 30mAh). As long as there is a string of batteries It will protect if the voltage is too high or too low. The better the consistency of the battery, the longer the power of the entire battery, and the better the performance
