Victron Energy Battery Balancer

I have a 24v series parallel battery bank in my RV. This balancer is the perfect device to make sure all of my batteries are charged equally and remain in balance.

I’m using these to balance my lithium batteries, and so far they’re doing their job really well. Very satisfied with the performance and reliability.

Good product

Muy bueno el equipo, lo necesitaba para una conexión entre paneles solares h batería

It's bn about a week, here's what I found. If using on lipo battery the bms will make it chatter,between batteries once fully charged. Between A&B hi volt inputs

High quality item! I absolutely love it. Definitely recommend!!

As I am a fan of Victron, this is one of the items I will give a negative review for. Per the manual as well as the advertisement in the product page, this item can be used in a 48v series configuration of 4x12v batteries. It states you have to purchase 3 in order to do it and provides instructions on how to configure it. I was hesitant because 3 of them makes it about 2x as expensive as buying any of the other units on amazon that will balance all 4 batteries at once. The reason for the 1 star is because the manual does not state how battery balancing works in a 4S series. In a 2S it would work just fine. This balancer only ever balances 2 batteries. It compare each one its connected to and balances them out. Forget the incredibly high voltage required for these to even turn on. Other reviewers have already posted the negatives on that. In a 4S, you need 3 units because the first balances battery 1 and 2, the second one balances battery 2 and 3, and the third one balances battery 3 and 4. The manual would have you believe that the balancers may communicate with each other somehow, but they dont. So battery 1 and battery 3 and 4, Battey, 4 and battery 1 and 2, etc, they dont know about each others voltage. In theory this would work, but im my case, almost always this will balance 2 batteries somewhere, but the ones farthest away end up over .2v off from each other. For example, Batt 1 - 13.50v, Batt 2 - 13.58v, Batt 3 - 13.66v, Batt 4 - 13.74v. If you look, no 2 batteries directly next to each other are off by .1v or more, so balancing will never happen. Batt 1 and Batt 4 are .24v apart. I have noticed that sometimes, the voltages are so off from the left to the right side, that the voltages on the low pair dont always reach a high enough voltage to even turn on in the first place. Sometimes because of the differences, the Internal BMS of the batteries kick on and shut down before the balancers even start working. For a 2S I would recommend these. In a 4S, these are a money pit.

This thing is perfect, it balances my 2x series 12v 200ah Lifepo4 setup as expected. I did a full discharge overnight then full charge today, now both batteries are sitting at the same voltage. This will extend the battery life and ensure I get full capacity when needed. Did some initial testing with a charger to see that the LEDs would light up as expected when the delta exceeded the voltage for each battery.

Can't really go wrong with victron, but not the cheapest....

não posso dizer nana .

Ho installato questo regolatore per una stazione di telecontrollo in montagna, collegato a 2 pannelli solari da 100W in configurazione a 24V. In un contesto isolato serviva un prodotto affidabile, e il Victron non ha deluso. Prestazioni reali: L’MPPT lavora in maniera molto efficiente anche con luce variabile e condizioni ambientali non ideali (nuvole, sole basso, parziali ombreggiamenti). La gestione della carica è sempre stabile e sicura. In combinazione con il Victron Energy BBA000100100 Balancer Batteria, il sistema mantiene le batterie perfettamente equilibrate, riducendo rischi di sbilanciamento tipici negli impianti a 24V. Punti di forza: Bluetooth integrato: con l’app VictronConnect monitoro tensione, corrente, stato della carica e log storici direttamente dal telefono. Per un impianto remoto è una comodità enorme. Affidabilità Victron: costruzione solida, firmware aggiornabile e funzionamento impeccabile anche in condizioni ambientali difficili. Compatibilità: perfetto con sistemi a 12V e 24V, adattamento automatico e ottima resa con pannelli di piccola e media taglia. Integrazione col Balancer: abbinandolo al bilanciatore batterie si ottiene un sistema davvero completo, stabile e duraturo. Cosa mi è piaciuto di più: Efficienza superiore rispetto ai PWM, resa costante anche in giornate non perfette App chiara, grafici utili e monitoraggio remoto affidabile In combo con il Battery Balancer, le batterie restano sempre equilibrate Dimensioni compatte e installazione semplice Cosa migliorerei: Prezzo sopra la media, ma giustificato da qualità e affidabilità Nessun display fisico (l’app compensa, ma per impianti remoti potrebbe servire un accessorio dedicato) Verdetto: Un regolatore MPPT che offre sicurezza e prestazioni professionali. Con 200W a 24V e il supporto del Victron Battery Balancer, l’impianto lavora in maniera ottimale e senza sorprese. Per chi cerca affidabilità in ambienti remoti e difficili, è una scelta che vale ogni euro speso.

El problema en un sistema Aislado de 24v, con baterías de 12v es que en muchas ocasiones una batería puede estar en 14.1v y la otra en 13.5, entonses si aumentas la carga al estar disparejas la del voltaje más alto se puede apagar por algo voltaje y en el caso de una descarga mayor la de menor voltaje se apagara por bajo voltaje, ocasionando qué no tengas la energía suficiente por voltajes disparejos, ahora que ya tengo el ecualizer battery ya pude aumentar más la potencia flotando mis baterías en 14.1 cada una.

I'm not even sure it works. The led came on once and never again. The instructions aren't a great help either. I am considering sending it back but waiting to see if it magically works again.
