Boosted Extended Range (XR) Battery Care Tips
Just recently sold a Mini-X with a restored XR battery using BERT Touch. The new owner asked what the best practices are for maintaining the battery long-term, so I put together a quick care sheet for him.
Before I send it over, I wanted to run it by the community here and see if there’s anything you would change, add, or disagree with.
Best Practices
Avoid storing fully charged for long periods
If you won’t be riding for several weeks, store the battery around 50–70% charge instead of 100%.
Don’t leave the battery fully depleted
Try not to leave the board at 0% for extended periods. Recharge after riding when possible.
Ride and charge regularly
Boosted XR batteries tend to stay healthier when used periodically rather than sitting unused for months.
Keep the board indoors
Avoid prolonged exposure to excessive heat, cold, or moisture.
Charging habits
It is OK to charge to 100% before riding. For long-term storage, a partial charge is preferred.
If storing long-term
Check the battery every few weeks and recharge if needed.
Important Notes
• The Boosted XR battery uses lithium-ion cells similar to those used in EVs and other high-performance electronics.
• Some balancing variation between cell groups is normal.
• Proper storage and regular use help reduce the chance of future battery imbalance issues.
Curious what long-time XR owners and BERT users think.
