ISDT BG-18S Professional Battery Meter & Balancer (4S–18S)

Take command of your high-voltage power systems with the ISDT BG-18S. Engineered specifically for professional UAV pilots and industrial drone platforms, this is one of the few portable tools capable of monitoring and balancing up to 18S battery packs with surgical precision.

While standard checkers stop at 8S, the BG-18S handles the heavy lifting for 12S, 14S, and 18S systems. Whether you are maintaining an industrial fleet or a heavy-lift cinema rig, this device ensures your expensive flight packs stay healthy and balanced.

Key Features

• Massive Cell Support: Supports 4S to 18S LiPo, LiHv, ULiHv, and LiFe batteries, making it indispensable for professional platforms like the DJI Matrice or Flyability series.

• Laboratory Precision: Features an advanced 32-bit processor providing voltage measurement accuracy down to ±0.005V.

• Smart Balancing: An automated balancing algorithm works to equalize cell voltages quickly, preventing cell drift and extending the cycle life of your batteries.

• Daylight Visible Display: The 2.4-inch IPS LCD screen offers 320x240 resolution with high brightness, ensuring you can read critical data even in harsh Australian sunlight.

• Wide Voltage Range: Operates safely across a 10V to 90V range to accommodate the most demanding power setups.

Why Choose the BG-18S?

Most pilots are familiar with the industry-standard ISDT BG-8S Smart Battery Checker, which is the perfect tool for everyday 1S to 8S FPV wings and quads.

However, for enterprise and industrial applications, the BG-8S reaches its limit. The BG-18S picks up where it leaves off, offering the same trusted ISDT reliability for high-voltage packs that require specialized monitoring.
