Battery Equalizer, Voltage Balancer 12V/24V/48V/60V/72V/96V Battery Bank for Lead-Acid Batteries and Lithium Battery Balancer

Just installed couple weeks ago. Between 2 12v 200amph lifepo in series. Had one of those cheap black units that blink with little led on side feeding low amp to other.This unit however tells what exact voltage of each battery is. During battery useage and charging they will go out .1 amo and immediately start to balance which you can see by mini arrow pointing towards weaker cell. They’ll be back in balance within minutes. If i were to build a 48v system by adding two more batteries i would purchase more of these units and mount on din rail. They seem to function perfectly. As with all these things, time will tell !

The reason why I am giving this four stars is because this can only work for two batteries you will need to add more in series for every two batteries you need to balance. Display is nice a product is a great idea since you could add as many batteries as you need to balance, but if you are only using four batteries you should not purchase this balancer.

Hace un tiempo lo compré y pensé que iba a ser un gasto innecesario pero resulta que mis baterías cargaban hasta 13.3 volt y ahora han superado los 14 volt lo que me dio mucha satisfacción pues esto ayuda a mejorar la eficiencia al máximo.

Simple, easy to connect, but the instructions, and the set up is complicated.

The media could not be loaded. I have been looking for something like this for awhile and was pleasantly surprised to find this here. I have 2 12 volt 150ah batteries that are linked together parallel to each other to produce a 12 volt 300 ah battery pack. This will allow me to charge/discharge at a balanced level between batteries to gain as much power as I can from the system. Was very easy to install, took less than 15 minutes and works great. It also has a nice screen showing total voltage between each battery and can work with several different battery chemistries. The real test will be time however if you don't see any update that means everything is working as intended.

Defective and in my case in order to return it to the specific ups drop-off, a 45 mile round trip, or pay a fee to return it to my local ups drop-off amazon continues to find ways for me to do less business with them

Hooked it up per instructions for two parallel 12V batteries. Reading from the lit up screen showed battery 1 was 100%, battery 2 was 52%, and during charging I didn't see any drop in battery 1, only battery 2 was gaining gradually until it's fully charged. Then, when it's discharging, only B 2 was dropping and there's no change in B1 (stayed on 100%, and no balancing was happening!) The voltage stayed the same on both though. Then if you cycled through B3, B4, it'd show 11% B3, 15% B4, or whatever! But there were only 2 batteries attached!? Would someone clue me in?I like the simple set up, compact device and clear cut read-out. I do worry about it burning out one day since there isn't any fuses or safety system.

Guess it works so good I forgot I even had 2 plugged in,they actually work great and have continuously for years now.
