20S 72V Li ion or 60V Lifepo4 Battery active Balancer and Lithium Equalizer with 5A Balance current

Our advantages with active Balance :

Our professional Power management chip which integrated battery overcharge, over-discharge, over-current, short circuit, disconnection, temperature detection and other protections

With large active balancing current, the balancing current can reach up to 10A, and the balancing voltage precision can be within 5mV.

Active will work in those process: 1. Active Balance will work throughout the whole charging process. 2. Controllable Balance in standby process, 3. Automatically starting balance when the voltage difference between cells exceeds 45mV

It solved the problem of low cycle times and short service life of battery packs due to inconsistent battery capacity, voltage difference, and internal resistance difference, making the product safer and more reliable, therefore prolong whole battery work life
significantly .

Solve the problems of low efficiency, small balancing current of general passive balancing methods. The application fields include power tools battery, photovoltaic battery,

Outdoor energy storage battery , battery replacement cabinets, electric bicycles battery ,or EV battery etc.

please contact us for the detail connection instructions if you need , I will send it by email to you without problems

Modules connected in series to work for more series battery pack with below connection methods .

FAQ with our active balancer bms :
1.what’s the difference with capacitor balancer in current markets ?
Our active balancer applied inductive balancer which will allow large current balance with much less energy loss than capacitor balance ,and also has much better safety performance even at conditions of large balance current .
2.What’s the balance methods with your active balancer :
Our active balancer adopt the energy transferring solution ,it does not like other active balancer which balance battery between two neighbouring cells from high cells to lower cells .
and our active balancer will balance all lower cells by transferring energy from whole system average voltage to lower cells with our unique dynamic algorithm
As neighbouring balance will cause such problems . the whole system consistency will be affected and became unbalanced when transfer energy simply between two neighbouring cells to others,and which also caused a lot energy loss .
3.How much max balance current with this active balancer ?
It rated 5A max balance current , and the balance current even can reach 5~7A when cells voltage difference are too big .
4.Can I install the active balancer inside of the battery together with BMS ? and will it drain the battery capacity completely ?
Yes , the active balancer was designed for the whole battery service period , it can be installed inside of the battery and without any safety problems in battery whole service period . it has no electrolyte linkage risk for long service time and it will not drain the battery remaining capacity due its low voltage cut-off protection automatically . the module will stop work when battery system voltage drop to its cut off voltage . and when the module stop work , the current consumption of our module will be very small which can be neglected and will not drain the battery completely .
5.Why did this active balancer has no switch to turn on or off manually ?
This Balance does not needs switch like others , it can automatically turn off the balancer when battery reach protection voltage , if user forget to turn off the manual switch while the balance still undergoing , it will take risk to the user battery and our device . our design without switch will meet all demand ,do not worry .
6.Will it deteriorate the low capacity cells when make balance ?
As our balance method is different comparing other capacitor active balancer , it will not deteriorate the low capacity cell with less charge and discharge ,in our current market ,most balancer active energy transfer directly to the low capacity cells , and therefore ,the low capacity cell will be frequently be charge and discharged ,and it will deteriorate the life of low capacity cells actually . our balancer will solve this problems by apply average voltage compensation solution .
7.why does the trickle balance current is necessary to keep battery consistency ?
Big balance current will cause the fake balance , the voltage of low cell will spring back after big balance current compensation . so the trickle battery current can keep the battery system in real consistency .
