QINIZX4S 12V 16.8V 1.2A Li-ion Lipo Lifepo4 LFP Battery Active Equalizer BMS Balancer Inductive Balance Lithium Battery Energy Transfer Board (4S)
Main highlights- Voltage balance accuracy: 30mV (typical value) between adjacent voltages; Balance current: When the Adjacent battery voltage difference is 0.1V~0.2V, balanced current in 0.5A-0.7A; Adjacent battery voltage difference is greater than 0.2V, maximum balanced current 1.2A. Static working current: 0.01mA; Under-voltage protection dormant voltage: The adjacent voltage difference is less than 0.03V and enters dormant state.
- 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: Not recommended to be compatible with low strings, The indicator light will flash and report an error. Before connecting the equalization board, be sure to check whether each battery is wired correctly, and do a good job of insulation. otherwise it will short-circuit and burn the board. LED on: balanced (corresponding to energy transfer balance between adjacent batteries); LED off: equalization ends; LED flashing: drop string indication/circuit malfunction.
- 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.

LitimeLiTime 48V Battery Equalizer, Active Balancer for 24V/36V/48V Battery Bank, Supports for LiFePO4 Lithium Battery, Lead Acid, Gel, FLA, SLA Battery, Perfect for RV, Solar, Trolling Motor, Off Grid
Main highlights- 【Up to 48V Battery Bank】The LiTime Balancer boasts 4 distinct connection ports, enabling seamless integration with battery banks as high as 48V. This versatility is ideal for constructing a robust 48V battery bank, achieved by combining 16 units of 12V batteries in a configuration of first 4 in parallel and then 4 in series. Furthermore, it's compatible with 24V, 36V, and 48V battery banks, making it a perfect choice for diverse applications, such as RVs,trolling motors, and off-grid systems
- 【Suitable for Multiple Battery Type】The LiTime 48V battery balancer is suitable for multiple types of batteries on the market, including LiFePO4 battery, lithium ion battery, lead acid battery, GEL,SLA (Sealed Lead Acid),FLA(Flooded Lead Acid) battery and all the other batteries that have a rated voltage that are within 3-20V, our battery balancer has you covered. our state-of-the-art battery balancer is compatible with an extensive range of battery types available in the market.
- 【Prolong Battery’s Life Span and Cycle Times】With this comprehensive active balancing functions, LiTime battery balancer not only optimizes battery performance but also extends their lifespan. You can harness the full potential of batteries, achieving longer cycle times and overall improved performance. Whether you're using it for your recreational vehicle, energy storage system, or any other application, LiTime battery balancer is your trusted companion for optimizing your battery's life.
- 【Auto Balance Mode and Standby Mode】The LiTime battery equalizer will automatically starts working when there is voltage difference between the connected batteries. And works until the voltage difference under 10mV. The maximum working current is 10A, which works for all 12V batteries at all capacity. If the battery bank have voltage difference less than 10mV, the equalizer will automatically turn into standby mode and only draw less than 5mA from the battery bank.
- 【Active Protection Functions】The LiTime battery balancer are equipped with reverse polarity protection and High Temperature Protection. Among these advanced protective features, we've incorporated a robust reverse polarity protection mechanism, offering you peace of mind against accidental wiring errors.
