Grin Satiator Programmable Charger
The charger that doubles your battery's lifespan. Program a charge ceiling (e.g. 80%) and the Satiator turns any pack into a longer-living one.
Safety notes
Always charge on a hard, non-flammable surface, never overnight unattended, and never block a doorway. Use a charger matched to your pack chemistry and voltage — mismatched chargers are a leading fire cause.
The Satiator is a programmable charger that lets you set the exact voltage you charge to. Charging to 80–90% instead of 100% dramatically extends lithium cell life, and the Satiator makes that a one-button affair. It handles 24V through 52V packs, so it follows you across builds.
It's expensive for a charger, but for anyone keeping a bike long-term — or running pricey packs — it pays for itself in battery longevity. The aluminum body runs cool and quiet, and it can be set for storage-charge levels before a winter layup.
Where to buy
Two paths — match your spend to the build. Quality picks last longer and come with real support; affordable picks get you rolling for less. Always confirm fitment, voltage, and connectors for your bike first.

Pro tips from our test team
- Charge to 80–90% for daily use and only to 100% before long rides.
- Set a storage charge (~60%) before any multi-week layup.
- One Satiator can serve multiple bikes at different voltages.
