Grator Battery

The official companion app for your Grator Lowrider — the remote-controlled mulcher built for slopes up to 70°.

Grator Battery connects to your Lowrider's 52V lithium-ion battery via Bluetooth and gives you real-time insight into your battery's performance. Know exactly how much charge you have left, check the health of individual cells, and catch potential issues before they become problems.

FEATURES

• Real-time battery level — See your exact charge percentage and voltage so you always know how much work time you have left.

• Cell health monitoring — Check the voltage of each individual cell in your 14S battery pack. Spot weak cells early and keep your battery in peak condition.

• Charge cycle counter — Track how many times your battery has been charged to understand its lifespan and plan replacements.

• Error diagnostics — Get instant alerts about any battery issues. The app reads error codes from the battery management system and tells you what's happening in plain language.

• Troubleshooting guides — Built-in guides help you resolve common issues on your own, no service call needed.

• Bluetooth Low Energy connection — Connects wirelessly to your Grator battery. No cables, no hassle. Just open the app and you're connected.
