21S Active Equalizer LTO Lithium Battery Energy Transfer Balance Board 72V Balancer ,Easy to Install

<ul><li>Before connecting the equalization board, check whether each piece of wiring is correct, insulation between the bottom board and the battery connection terminals is required to prevent burnout.</li><li>No external power supply is required,The working principle is Capacitor fit transfers the charge transporter, use the internal energy transfer of the battery to transfer and balance the entire battery pack.the equalization board can be connected to the battery to start the equalization work.</li><li>With sleep protection, when the voltage is lower than 3V, it will automatically stop and enter the sleep state to reduce the damage to the battery.</li><li>Using the original ultra-low internal resistance MOS, 2OZ copper thickness PCB, equalizing current 0-5.5A, The more balanced the battery, the lower the current.</li></ul>

Assembled Product Weight

Notice:This balancer supports 17~21s batteriesThis is an equalizer, it could balance the voltage difference between battery series to make the batteries more durable, and the battery life would be longer, It's not BMS, so it does not have the over-voltage, over-current and over discharge protection, but it can work with BMS together, It's suitable for Li-ion and batteries, could be used with any capacity of batteries, Due to the balance current is fixed, so the balance time for large capacity of battery is slow, and for small capacity battery is fastSuitable battery types: Li ion//LTOSingle cell voltage range: Li ion / version:2.7-4.2VLTO version:1.8-4.2VVoltage equilization accuracy: 5mV(Typical value)Equalization method: The patented balance architecture fit capacitor mode, the entire battery group at the same time to participate in the active balance of energy transferBalancing current: Voltage difference is 0.08V, balance current is 1A, the voltage difference is directly proportional to the balance current, the maximum allowable working current is 6.0ASleep voltage for undervoltage protection: Li ion / : below2.7VLTO:below1.8VWorking temperature: -10°-60°Whether an external power supply is required: No external power supply is needed, and the whole group is balanced by internal energy transfer of the batteryTechnical parametersOperating voltage 1.8V-4.5V, suitable for li-ion, , lithium titanate.Working principle: the balanced work will be started when the balanced board is connected to the battery. The original ultra-low internal resistance MOS and 2OZ copper thick PCB are adopted, And the balanced current is 0-5.5a, the more balanced battery, the smaller balanced current.The static current is around 12 mA. It is recommended that the battery capacity should be in the range of 60-300AH!With undervoltage dormancy protection, if the voltage is less than 1.8V, it will automatically stop into the dormancy state, standby power consumption is less than 0.1 mA.Connection definition:BC- Connect the first string of positive pole of the battery packBC2 Connect the second string of positive pole of the battery packBC3 Connect the 3rd string of positive pole of the battery pack.BC4 Connect the 4th string of positive pole of the battery pack.BC5 Connect the 5th string of positive pole of the battery pack.BC6 Connect the 6th string of positive pole of the battery pack.BC7 Connect the 7th string of positive pole of the battery pack.BC8 Connect the 8th string of positive pole of the battery pack.BC8 Connect the 8th string of positive pole of the battery pack.BC9 Connect the 9th string of positive pole of the battery pack.BC10 Connect the 10th string of positive pole of the battery pack.BC12 Connect the 12th string of positive pole of the battery pack.BC13 Connect the 13th string of positive pole of the battery pack.BC14 Connect the 14th string of positive pole of the battery pack.BC15 Connect the 15th string of positive pole of the battery pack.BC16 Connect the 16th string of positive pole of the battery pack.BC17 Connect the 17th string of positive pole of the battery pack.the total positive pole of the battery packRelated Products:battery balancer,battery balancer 12v
