Important Compatibility & Safety Notes

Please ensure the battery voltage matches your motor and controller before ordering. A 36V battery and 48V battery are not interchangeable unless the complete electrical system is specifically designed for the selected voltage.

Check the battery dimensions, mounting system and electrical connector before purchase.

Only use the supplied or a correctly specified compatible charger. Do not charge a lithium-ion battery unattended or use a battery that is swollen, damaged, excessively hot or otherwise abnormal.

The IP65 rating does not mean the battery is waterproof or suitable for immersion. Keep charging connections dry.
