Power that keeps up with your family.
Rosa's battery system is modular, expandable, and designed for the way families actually move — from morning walks to cross-country flights.
The Travel Battery.
Modular. Expandable. Flies with you.
Rosa's 36V Travel Battery is a modular power system designed around how families actually travel. It ships with two packs — add up to two more as your needs grow. Each 99Wh pack stays within airline carry-on limits, so Rosa goes wherever you go.
The system is lightweight, Canadian-made, and built on trusted Lithium Ion cells by LG. Every pack has its own independent Battery Management System monitoring voltage, temperature, and current in real time.

Battery Safety
Every Glüxkind battery includes an independent Battery Management System (BMS) that monitors voltage, temperature, and current in real time — protecting against overcharging, over-discharging, and short circuits.
All batteries and chargers are independently tested and certified to international safety standards.
Essential Guidelines
Only use Glüxkind-certified chargers.
Charge indoors, in dry conditions. Do not charge unattended.
Disconnect from power once charging is complete.
Do not disassemble, puncture, short-circuit, or expose the battery to fire or heat above 60°C / 140°F.
Do not use or charge a battery that has been submerged, dropped from height, or visually damaged.
Do not charge with wet hands or expose the charger to water.
Store in a dry location at room temperature. Avoid prolonged sun, heat above 50°C / 122°F, or cold below 0°C / 32°F.
For extended storage, start at roughly 50% charge. Check every three months and recharge to 50% if needed. Store away from flammable materials.
If your battery appears damaged or is behaving unexpectedly, stop using it and contact support.
