17S 20S 21S 5A Lithium Battery Balance Board Battery Protection Board for Li Ion LTO 1.8V?4.5V

Feature: 1. WORK DETAIL: The working voltage is 1.8V?4.5V, suitable for NCM ternary polymer lithium batteries (Li ion), lithium iron phosphate batteries, and lithium titanate batteries (LTO). 2. USAGE TIPS: The voltage difference of each battery must be within 0.5V. When the battery voltage difference does not arrive above 0.1V, the lamp on the balance board is mistakenly triggered. When a lamp is lit, there is actually no balanced current, and after a period of time it will automatically go out. Therefore, we recommend reinserting and unplugging the data cable to solve the problem. 3. BALANCE DETAIL: The balance current is 0?5.5A, and the more balanced the battery current is, the smaller the battery current is. The connection position of the sleep switch is reserved. The working current in the sleep power off mode is less than 0.1mA, and the balance voltage accuracy is within 5mv! 4. UNDERVOLTAGE PROTECTION: The battery balance board only detects the B1 battery voltage. When the B1 voltage NCM LFP less than 2.7V or LTO less than 1.8V, the equalizer automatically stops entering the sleep state, and the standby power consumption is less than 0.1mA. 5. PCB BOARD: Made of PCB board, this battery balance board is wear resistant, and corrosion resistant, and has a long life span. Specification: Item Type: Lithium Battery Balance Board Material: PCB Working Voltage: 1.8V4.5V Suitable Batteries: NCM ternary polymer lithium battery (Li ion), lithium iron phosphate battery, lithium titanate battery (LTO). Package List: 1 x Lithium Battery Balance Board2 x Cable Note: 1. Before connecting the balance wire to the balance board, be sure to check whether the connection of each part of the battery pack is correct, and do a good job of insulating the board bottom and the battery string connection terminals. Otherwise, it will short circuit and burn the board. Tip: This balancer board is backward compatible by default. For example. If used for 20S, the last row B21+is empty, and so on.2. Equalizing the voltage requires time, and heating is a normal situation that does not take effect immediately after plugging in.WORK DETAIL: The working voltage is 1.8V?4.5V, suitable for NCM ternary polymer lithium batteries (Li ion), lithium iron phosphate batteries, and lithium titanate batteries (LTO).
