## Description

A battery bank designed around one voltage has different balancing needs from a 24V, 36V or 48V system. The Power Queen Battery Equalizer supports all three bank voltages, with four connection ports for balancing batteries in series. It works with LiFePO4, lithium-ion and lead-acid batteries, including GEL, SLA and FLA types, making it useful across RV, marine, trolling motor, home, solar and off-grid setups.

Active balancing responds to voltage differences automatically, helping keep the batteries in a bank balanced during use.

## Technical overview

The equalizer detects when the voltage difference in the battery system exceeds 10mV and balances the batteries until the difference falls below 10mV. Once balanced, it enters standby mode, drawing 5mA. It can remain connected for ongoing balancing, supporting battery-bank maintenance without requiring manual balancing each time a voltage difference is detected.

- Type: Battery equalizer with active balancing
- Supported bank voltages: 24V, 36V and 48V
- Battery types: LiFePO4, lithium-ion, GEL, SLA and FLA
- Battery rated voltage range: 3–20V
- Dimensions: 12.9 × 6.9 × 2.8 centimetres
- Included: 4 sets of connecting wires, M8 terminals and insulating rubber sleeves

For buyers comparing a balancer intended for one bank voltage with a unit that supports several, this model offers flexibility across 24V, 36V and 48V systems. Reverse-polarity and high-temperature protection are built in to support safer operation during installation and use.

## Everyday compatibility

Use the equalizer with supported battery types in a 24V, 36V or 48V battery bank. That range makes it suitable for applications such as an RV power system, a boat or trolling motor, or an off-grid and solar storage setup. Its support for both lithium-based and lead-acid batteries lets you choose the compatible battery chemistry for your system without needing a different equalizer for each of these listed types.

For a series-parallel arrangement, connect the batteries in parallel first, then connect them in series. Following that sequence helps you set up the bank according to the product’s stated connection guidance.

## Usage tips

Plan the bank voltage and battery connections before installing the equalizer, then use the supplied connecting wires, M8 terminals and insulating rubber sleeves for the connection. Keep the positive and negative connections correctly oriented, reverse-polarity protection is provided, but correct wiring remains important. Once connected, the equalizer monitors voltage differences and balances automatically, then switches to its low-power standby mode when the difference is below 10mV.

This automatic cycle is useful where a battery bank stays in service for ongoing RV, marine or off-grid power needs. Instead of treating balancing as a one-time task, the unit can remain connected and respond as voltage differences arise.

## Before you decide

**Which battery-bank voltages does it support?** It supports 24V, 36V and 48V systems, using four connection ports.

**Which battery chemistries can it balance?** It supports LiFePO4, lithium-ion and lead-acid batteries, including GEL, SLA and FLA types, with a rated voltage range of 3–20V.

**How does automatic balancing work?** It activates when the voltage difference exceeds 10mV and balances until the difference is below 10mV. It then enters standby, drawing 5mA.

## Buying verdict

For an RV, marine, trolling motor, solar or off-grid battery bank, the Power Queen equalizer brings automatic active balancing to 24V, 36V and 48V systems. Its broad support for listed battery chemistries, automatic response to voltage differences and low-power standby make it a practical fit for buyers who want ongoing balancing across these common bank voltages.
