Guanlan 29.2V 30A LiFePO4 Battery Charger for 24V Systems – 0V Wake-Up, Safe Protections, Fast Charge

Smart, safe charging for 24V LiFePO4 systems

The Guanlan 29.2V 30A LiFePO4 battery charger is built to deliver a precise, high-efficiency charge to 24V LiFePO4 packs. With a capable 30A output and a target of 24V (25.6V when charging), it can bring a 24V 150Ah battery to full in about five hours under ideal conditions. This is ideal for days when you need a quick top-up between use cycles or after periods of light activity.

Designed with safety and longevity in mind, the charger includes robust protections and wake-up features that help you manage packs that have sat idle. When a battery has been resting with a BMS cut-off, you can engage the 0V wake-up function to re-start charging and regain usable capacity. In addition, a software timeout offers a 14-hour auto-stop window to prevent prolonged operation, which adds an extra layer of protection for both the charger and the battery.

Durability and cooling are built into the hardware. The unit uses a tough aluminum alloy housing with a surface finish that resists wear, and it includes a dedicated cooling fan and a designed airflow pattern to promote heat dissipation during long sessions. This combination helps keep temperatures stable, which supports more consistent charging performance even in warmer environments.
