Q & A for balancer

 Q: Why active bms more expensive than passive bms?

A:Active balancer is for extending battery spanlife /Keeping your pack in healthy /reviving old battery /save your purchase frequency of cells,not a cheap options ,can use in series for high volt of pack ,no ah capacity limitation,it's more fair to compared balancer price to your battery pack cost


Q: How many balance current ?

A: Normally it's can reach 6-10A ,but you won't have this large volt difference of pack , 300MV=1A, also depends on balancing time & battery capacity


Q:What's the differences of 1S to balancer module 3S 4S 5S 6S 7S 8S?

A: Same function ,difference apperance, balance module without cable included ,no led option


Q: 1S balancer can mix with balancer module?

A: No dear, 1S with different components inside


Q: Did battery balancer equalizer with monitor function?

A: No ,active balancer mian function is balancing volt of each cell , 100% active , no waste energy of pack .so no other function who need power from pack .


Q: Did balancer can use together with bms ?

Yes they can work together , balancer for balancing bms for making sure battery in safe range


Q: What's bad & goods of balancers?

Good, strong balance ,revive old battery ,testing bad cells,

Bad, while with large volt differences ,gonna with low frequency voice


Q: How to choose balancer for my battery pack ?

A: 1S balancer use for 1 series of battery pack ,no capacity limitation ,you can connected in series to balance whole bank

If u got 4S battery pack , u can use 4 pcs 1S or 1pcs 4S balancer module 

If you got 16S battery pack ,u can use 16pcs 1S or 4pcs 4S balancer module ,or 2 pcs 8S balancer module


Q:What is active balancing tech

A:Matching the soc of each cell ,active cell balancing redistributes charge during the charging and discharging cycle,unlike passive cell balancing ,which simply dissipatescharging during the charge cycle,thus active cell balancing increased system run-time,and can increase the charging effeciency,active balancing requires a more complex ,larger footprint solution ,not a cheap solution


Q: What else benbv  u can offer ?

A: Lithium ion batteries,chargers, obc chargers, ev cable and connectors,active bms ,passive bms.
