Ideal for 24V and 48V systems, it supports scalable setups with up to three balancers for 48V banks, integrates with smart monitoring tools like the BMV-702, and features an alarm relay for real-time status alerts—ensuring your expensive battery investment lasts longer and performs optimally. ## Description The problem: the life of an expensive battery bank may be considerably shortened due to unbalanced charge status. A slightly higher internal leak current on one of the battery in a bank of multiple 24- or 48-V serial/parallel batteries would cause a lack of charging of that battery and connected batteries in parallel, and the overload of the connected batteries in series. The solution: balance the batteries. Battery Balancer balances the charge status of two 12V batteries connected in series, or multiple parallel chains of serial connected batteries. If necessary, several balancers can be used in parallel. A 48V battery bank can be balanced with three Battery Balancers. Normally open alarm relay It closes when the red LED is turned on and opens when the same LED is turned off. Even more internal information and control with BMV-702 Battery Monitor Average Point monitoring function. Review: Can't really go wrong with victron, but not the cheapest.... Review: não posso dizer nana . ## Features - Victron Energy Battery Balancer eliminates the effect of load imbalance and improves the life of your battery bank - A 48V battery bank can be balanced with three Battery Balancers - The Battery Balancer equalizes the state of charge of two series connected 12-Volt batteries, or of several parallel strings of series connected batteries ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01DH6B2D2 | | Battery Type | Lithium | | Best Sellers Rank | #75,146 in Automotive ( See Top 100 in Automotive ) #165 in Power Inverters | | Brand Name | Victron Energy | | Compatible with Vehicle Type | Schiff | | Customer Reviews | 4.4 4.4 out of 5 stars (481) | | Global Trade Identification Number | 08719076020950 | | Item Dimensions D x W x H | 11.9D x 25.4W x 28.7H centimeters | | Item Weight | 0.24 Kilograms | | Manufacturer | Victron Energy | | Manufacturer Part Number | BBA000100100 | | Number Of Cells | 6 | | Resistance | 12 Ohms | | Size | 7.0cm L x 14.8cm W x 21.0cm H | | Terminal | M8 Terminal | | Unit Count | 1 Count | | Voltage | 12 Volts | ## Product Details - **Battery cell composition:** Lithium - **Brand:** Victron Energy - **Size:** 7.0cm L x 14.8cm W x 21.0cm H - **Vehicle service type:** Schiff - **Voltage:** 12 Volts ## Images ![Battery Balancer - Image 1](https://m.media-amazon.com/images/I/71+BR4OJIkL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: When the battery goes over voltage does the unit move the power to a lower voltage battery or does it just dissipate the power in the heat sink?** A: No, it dissipates power from the higher battery. **Q: Can this be used to balance my 24v lithium battery that is made up of 8 x 3.2v series-connected cells?** A: No. This is for balancing 12v batteries in series that already have their own BMS. **Q: Do connect the 4battery bank with the 4/0 cable (I use 4/0 ) or do you connect with 18 awg wire, which is min. spec. of wire connect battery balancer?** A: Hi, the 4/0 won't fit in the Battery Balancer's connectors. Also, the current that will flow in it does not justify the use of a 4/0AWG wire. I'd go with Victron's recommendation : 18AWG **Q: Will this protect both the starting (lead acid) and an auxiliary lipo battery. will it protect the alternator?** A: The Battery Balancer equalizes the state of charge of two series connected 12V batteries, or of several parallel strings of series connected batteries. When the charge voltage of a 24V battery system increases to more than 27V, the Battery Balancer will turn on and compare the voltage over the two series connected batteries. The Battery Balancer will draw a current of up to 1A from the battery (or parallel connected batteries) with the highest voltage. The resulting charge current differential will ensure that all batteries will converge to the same state of charge. If needed, several balancers can be paralleled. A 48V battery bank can be balanced with three Battery Balancers. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by P***R on 9 April 2025* Can't really go wrong with victron, but not the cheapest.... ### ⭐⭐⭐⭐⭐ Review *by M***. on 1 May 2023* não posso dizer nana . ### ⭐⭐⭐⭐⭐ Review *by G***O on 9 September 2025* 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. ## Frequently Bought Together - Victron Energy Battery Balancer - Victron Energy SmartSolar MPPT Solar Charge Controller (Bluetooth) - Charge Controllers for Solar Panels - 100V, 50 amp, 12/24-Volt --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/253962841-battery-balancer](https://www.desertcart.pt/products/253962841-battery-balancer) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-28*
