1A - 3A Active Balancer Equalizer BMS For LTO Lithium Polymer LiFePO4 Lead Acid Battery
The QNBBM Active balancer 1S series is no limitation for using on big voltage battery pack whatever it is 100V 200V 300V 400V or 600V, 800V, or more. If the single cell voltage is 3.2V, then the 600V lifepo4 battery pack series by 200 string cells will need to use 200pcs 1S QNBBM active balancers to work.
1S 2.0V 2.3V 2.4V 3.2V 3.7V 4.2V 4.3V Active Balancer Battery Equalizer For Lithium Polymer, LTO, 2.0V Lead Acid/Vrla Battery, LiFePO4 and Li-ion 18650 DIY Active Balancer(Energy Transfer/Dynamic)
Buyer attention:
You need to order no less than 2pcs. Otherwise it is useless.
1 Application
The balancers can be used for various lithium ion batteries both cylindrical or prismatic batties: LIFEPO4 or LiPO,LIMN2O4,Lithium-ion Li-ion,LiPolymer battery pack etc.
for different brands such as Headway ,A123,Thundersky,Winston,CALB,GBS,E&J, SINOPOLY,PEAK ETC ,YINLONG,TOSHIBA, KOKAM,all lithium rechargable batteries whose voltage range is 2V~5V range.
2 Main Function
Keep your batteries volt difference within 10mV
Prolong your battery lifespan 2~3 times!
