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 !

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.

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.

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.

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

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

I bought 2 of these battery balancers for a 24v battery bank (two 12v batteries in series). I ran a test over 2 weeks comparing my lifepo4 batteries both with and without these balancers (I ran test on two different battery banks). After 2 weeks of testing bank with and without balancer there were zero difference in voltages. Both bank whether passively or actively balanced were the same (13.4 / 13.5 and 13.6 / 13.7 passive balancing and 13.3 / 13.4 and 13.5 / 13.4 using this active balancer). I truly believe these Chinese mass produced balancers are just a gimmick and simply allow you to see individual voltages of a 24v battery bank using 12v batteries placed in series. End results: Neither bank whether passive or actively balanced had same voltage (both off by .1v) when placed in series.

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

ne fonctionne pas des le premier branchement il a fait de la fumée Commander un deuxième et ne fonctionne pas à éviter de la brie scrap

LE module balanceur fonctionne parfaitement, apres ue le 1 er soit défectueux , la compagnie m'en a envoyé un autre rapidement et sans frais. Je peux dire que c est formidable puisqu j ai augmenté ma capacité de batterie a 2 ans d 'écart, donc imposible d'avoir la meme batterie avec le meme BMS. CEla fait la job a 100%.

Pour mon système solaire

Installer pour maintenir mes deux batteries LifePo4 égales pendant l’hiver qui sont en storage , en attente de les réinstaller dans mon campeur au printemps, garde mes deux batteries égales , va réinstaller cette unité ce printemps dans mon campeur sur les batteries pour garder la charge égales entre les deux. Fonctionne bien .
