Litime 48V Battery Equalizer Active Balancer for 24V/36V/48V Banks — Up to 10A, Multi‑Chemistry Support

LiTime 48V Battery Equalizer actively balances 24V/36V/48V battery banks to reduce voltage differences, extend battery life, and improve system reliability.

If you run multi-bank battery systems in an RV, off-grid solar array, trolling motor, or home backup, mismatched voltages between 12V cells reduce usable capacity and shorten battery life. The LiTime 48V Active Balancer connects across up to four 12V segments and redistributes energy until cell voltages are within 10mV, then drops to a low-power standby. Built for a wide range of chemistries — including LiFePO4, lead-acid, GEL, SLA and flooded batteries — it brings safer, more consistent performance to 24V, 36V and 48V configurations.

How does the LiTime equalizer improve my battery bank's performance?

The unit actively transfers charge from higher-voltage segments to lower-voltage ones, preventing imbalances that waste capacity and accelerate wear. By keeping voltages closely matched, the system helps batteries deliver more usable energy per cycle and maintain healthier long-term behavior.

• Active balancing until voltage difference is under 10mV for tight matching.
• Maximum balancing current up to 10A to handle various charge/discharge states.
• Automatic standby draws under 5mA when balancing isn’t required, preserving bank charge.

Which battery types and voltages does it support?

LiTime designed this balancer to be chemistry-agnostic within typical 12V segment ranges, so it works with LiFePO4, lithium-ion, lead-acid (FLA), GEL and SLA packs. The four connection points allow assembly into 24V, 36V or full 48V banks, giving flexibility for many installations.

• Compatible with 3–20V per segment rated batteries, covering most 12V modules.
• Works in 24V, 36V and 48V battery banks via four connection ports.
• Suitable for RVs, solar storage, marine trolling motors, and home backup systems.

What safety and protection features are included?

The balancer incorporates several protections to minimize installation or operational risks, including reverse polarity and high-temperature safeguards. These protections help prevent damage from wiring mistakes and excessive heat, which improves overall system safety.

• Reverse polarity protection to reduce risk from incorrect connections.
• High-temperature shutdown to prevent overheating and thermal stress.
• Product liability coverage via AIG for added assurance (policy effective May 22, 2026).

How does installation and daily operation look?

Installation requires connecting the four balancer ports across the battery segments in sequence; once connected it operates automatically whenever imbalances exceed its threshold. The device is practically maintenance-free: it balances during voltage differentials and returns to low-draw standby when voltages are matched.

• Simple four-terminal wiring for typical 4-segment banks (follow polarity markings).
• Automatic start/stop behavior — no periodic calibration needed.
• Low standby current (<5mA) so it won’t noticeably drain the bank when idle.

Who is this for: The LiTime 48V Active Balancer is best for homeowners, RV owners, marine users, off-grid solar installers and hobbyists who build multi-12V battery banks and want to maximize usable capacity and lifespan. It’s particularly useful if you mix battery ages or chemistries within a bank, need reliable balancing without manual intervention, and want protective features like reverse polarity and over-temperature safeguards. If you assemble 24V–48V systems from 12V modules and need automatic, efficient balancing with minimal maintenance, this unit fits those needs.
