IP68 Waterproof & Dustproof Design
The standout feature of the TR24 battery monitor is its IP68 rating (certified per test standard: immersed under 5 m of water for 1 hour). The entire housing is specially engineered for waterproofing — sealed at the front bezel joints, button seams, rear cable outlet, and mounting screws — to prevent ingress in high-humidity or splash-prone conditions. Ideal for marine battery banks, outdoor power equipment, and other wet or damp environments.
Key Functions
As a coulomb counter / battery monitor, the TR24 provides long-term real-time monitoring and is compatible with Li-ion, LiFePO₄, Sodium-ion, and Lead-Acid batteries. It features a TFT color screen with a wide viewing angle, displaying 6 parameters simultaneously on one screen — SOC (remaining capacity %), voltage, current, and more — so you can assess battery status at a glance. Screen brightness and standby brightness are both user-adjustable; the display can be set to dim or go black in standby mode to save power. It supports shunt pairings of various ratings, with a maximum peak current of 500A. 👉 Please refer to How to choose the appropriate shunt specification? for detailed shunt specifications.
