Frequently Asked Questions:

• Does the warranty differ for heated batteries? No, the 12 year warranty also covers heated batteries.
• How do I know if I need a non-heated vs heated battery? It depends on where you operate and store your cart. A lithium battery must be above 30°F internally to charge. If your cart is stored in a space that keeps the battery above this temperature, a standard battery works fine. For cold storage or outdoor, a heated battery is recommended to ensure reliable charging.
• Can I overcharge or over-discharge the battery? Our BMS helps prevent both. Best practice is to use a lithium-compatible charger and avoid repeated deep discharges.
