Installation Considerations
- Measure the available installation space before purchasing.
- Allow additional clearance for cables, connectors and battery access.
- Secure the mounting holder to a structurally suitable surface.
- Use appropriate fasteners for the equipment and operating environment.
- Protect the battery from excessive vibration, impact, moisture and heat.
- Route power cables away from moving parts and sharp edges.
- Verify correct polarity before connecting the battery to equipment.
- Use appropriate overcurrent protection and wiring for the application.
- For moving vehicles or mobility devices, confirm that the mounting system can withstand expected vibration and mechanical loads.
36V Battery Power and Current Capability
The BX3694G has a nominal output voltage of 36V and an operating voltage range of approximately 30V to 42V.
Its 10A maximum continuous discharge rating makes it suitable for equipment requiring up to approximately 360W at nominal battery voltage.
For temporary higher-current requirements, the battery has a published burst discharge rating of 15A for up to 10 minutes.
| Operating Condition | Current | Approximate Power at 36V |
|---|
| 5A Load | 5A | 180W |
| 8A Load | 8A | 288W |
| Maximum Continuous | 10A | 360W |
| Maximum Burst | 15A | 540W |
Power values are calculated at 36V nominal. Actual power changes as battery voltage varies during discharge.
Motor Controller Compatibility: A motor's advertised wattage does not necessarily indicate its maximum battery current. For example, a nominal 350W motor may be connected to a controller that draws more than 10A continuously or exceeds 15A during acceleration. Always check the controller's battery-current limits, not just the motor wattage.
