XT90 Battery Status Plug – F / E / S Marker

Boost MeXT90 Battery Status Plug – simple, tight-fit plug to clearly mark your batteries as Full, Empty or Storage. No more guessing in the field. Functional, durable and easy to print.

This is a tight-fit XT90 plug cap designed to clearly mark the battery status of your LiPo packs.

The model includes three clearly marked positions that allow you to indicate the current state of the battery:

• F – Full
• E – Empty
• S – Storage

Simply rotate or reinsert the plug to show the correct status.

Why this model?

During outdoor trips or field sessions with multiple batteries, especially when using identical packs, it’s very easy to lose track of which battery is charged, empty, or in storage mode - this plug solves that problem once and for all.

With this system, you always know exactly which battery is ready to use.

Design features

• Very tight fit on the XT90 connector
  Designed to stay firmly in place, so it won’t fall out easily or wear out too quickly over time.
• Clear and readable markings
  F / E / S are easy to recognize even at a glance.
• Two printing options
  • Multi-color version using AMS (for highlighted letters)
  • Single-color version without AMS

Printing notes

• Prints cleanly on most common filaments (PLA, PETG recommended)
• AMS version allows easy color separation for the letters
• Single-color version works perfectly without AMS
