Description 4S 5A Battery Energy active equalization Balancer. HELTEC 4S DESCRIPTION: This is a HELTEC 4S LiFePo4\lithium-ion 5A equalizer used for 12V battery pack. This device acts as a balancer/equalizer to balance the capacity of cells inside 12V battery pack. This is not a Bluetooth balancer/equalizer. This can be used in lithium batteries of any type including 18650/21700/32650/38120/66160 and any type of prismatic cells etc. This can be used in lithium battery applications including solar, RV, Electric bikes, Skate board, camping, Boat, Power tools, Lawn moving and household energy storage systems. This can be used for 3S and 4S battery pack configurations. This is manufactured by Heltec. DESCRIPTION SPECIFICATION SIZE 1.5*0.7*0.5 In weight 1.7 ounces There are two different types of Battery equalizers: Passive Battery Equalizer or balancer(Passive balancers) Active Battery Equalizer or balancer(Active balancers) The active battery equalizer in this method the battery equalizer have inductor or capacitors to balance the batteries they will use using their extra energy that stores in the battery with higher voltage to charging the other battery that has lower voltage so the active battery equalizer has higher efficiency than the passive type but it is expensive. We also sells heltec 6s,8s,14s,16s,21s and inductive balancers like 4s 1.2A, 8s 1.2A, 14s 1.2A, 17s 1.2A, 4s 10A and 8s 10A Inductive balancers. What you will get: Balancer- 1 Copper crimp ring- 5 rings Technical index Product model 4s 6s 8s 14s-16s 16s-21s Applicable string number 3/4s 5/6s 7/8s The same The same Applicable battery type LI-ION/LIFEPO4(LITHIUM IRON PHOSPHATE)/LTO cells Working range of signal voltage 2.0 to 4.5V voltage equailization accuracy 5mv(typical) Under voltage protection sleep When the adjacent voltages vary to 0.1V then the balancer/equalizer will active until voltages of the adjacent cells are equal, Otherwise balancer is in Off position. Product size(mm) 55*50*16 80*50*16 105*50*16 115*97*25 145*113*18 Working environment temperature 10 ͦ C-60 ͦ C External power Without external power supply, the whole group is balanced by energy transfer. https://srikobatteries.com/product/4s-5a-battery-energy-active-balancer/
