Sterling Power 24V Battery Balancer PN: BAL24

Sterling Power 24V Battery Balancer PN: BAL24

Overview

Maximize the life and performance of your 24V battery bank with the Sterling Power BAL24 Battery Balancer. When linking multiple 12V batteries in series to build a 24V system, natural variance in internal resistance and age can cause individual batteries to drift out of balance. One battery ends up overcharging while the other undercharges, drastically shortening their overall lifespan.

The BAL24 solves this issue effortlessly. Designed as a plug-and-play unit, it actively redirects current to ensure equal voltage across all connected batteries. Equipped with clear digital dual-voltage screens, you get instant visibility and peace of mind knowing your off-grid, marine, or commercial battery setup is running safely at peak efficiency.

Key Features & Benefits

Universal Compatibility: Designed to balance both Lead-Acid (AGM, Gel, Flooded) and Lithium (LiFePO4) 12V battery banks wired in series.
True Plug & Play: No complicated setup, programming, or manual adjustment required. Simply connect the pre-fitted ring terminals and let the balancer do the rest.
Real-Time Digital Displays: Features two built-in display screens showing the live individual voltage of both batteries in the 24V series string.
Scalable System Architecture:
24V System: Requires 1 unit
36V System: Requires 2 units
48V System: Requires 3 units


Stackable Balancing Power: Need faster balancing current for larger-capacity battery banks? Simply stack multiple BAL24 units in parallel via the 8mm ring terminals.

How It Works

When two 12V batteries are connected in series, the BAL24 constantly monitors each battery's voltage level. If a voltage difference is detected, the balancer transfers energy from the higher-voltage battery to the lower-voltage battery until equilibrium is reached.

Left Screen: Displays voltage across 0V to 12V (Red & White wires).
Right Screen: Displays voltage across 12V to 24V (White & Black wires).

Installation Guide

Installation takes only a few minutes using the pre-terminated M8 (8mm) ring terminals.

Important Wiring Connection:**
Red Cable: Connect to 24V Positive (+)
White Cable: Connect to 12V Centre Point (Series Link between Battery 1 Positive & Battery 2 Negative)
Black Cable: Connect to 0V Negative (-)
