Battery equalizer battery balancer for 4pcs 2.4V/3.6V/6V/9V/12V battery connected in series

Product Introduction
HA02 battery equalizer is used for the batteries which are connected in series to keep the voltage of batteries are equal when the batteries are charging or discharging.
When the batteries work in series connection, the batteries voltage maybe will be not same due to the difference of each cell chemical composition and temperature. And each battery's selfdischarge rate also different. So even the batteries not work, their voltage of series batteries will be also different. These differences will cause battery lost balance, this means maybe one battery is overloaded and the other is insufficiently charged. The voltage difference will be increased with the battery repeated charge-discharge process. This will result in premature failure of the batteries.The battery equalizer is used for solve these problems.
Product Features
•Energy transfer type equalize.
It can compensate for batteries with two sides. The equalizer starts to work when there are 10mV between two batteries. The current will flow from a higher voltage to low voltage,eventually reach equilibrium. It can connect with battery system with 24 hours , to keep the system energy balance automatically, no need manual maintenance.



• Used for different type of battery systems.
HA02 battery equalizer is suitable for lead-acid batteries(VRLA), lithium iron phosphate batteries(LFP), nickel-cadmium secondary batteries(Ni/CD), and nickel-metal hydride secondary batteries(Ni/MH). • Used for any n*(2.4V/3.6V/6V/9V/12V) batteries.
It starts work when the voltage higher than 2.4V, it means that this equalizer can be used in a single cell battery range from 2.4V to 12V. One equalizer can connect 4 batteries once a time, if battery less than the 4, the extra cable can be vacant (positive and negative terminal should be avoided), does not affect the equilibrium effects. The equalizer is not affected with battery connection way, no matter in series or in parallel, both can work.• No damage to the battery


• Very low power consumption


• Reverse polarity protection


• Moisture-proof and waterproof

•Installation


Connect it as the following order:
1.Red cable connect positive/+ pole. Black cable connect negative/- pole
2.Connect the batteries as the pictures,You can connect all + pole firstly,and then - pole to avoid short circuits.
Note:
1.If there are extra cables, please leave the tubes of the terminals on it to avoid short circuits.
2.Please avoid any of the 8 terminals touching each other.
