10C Continuous / 20C Burst Current Capability
Estimated Car Audio Amplifier Support — 14.6V
Calculated using the 10C continuous cell rating, 14.6V and 80% Class D amplifier efficiency. Alternator columns allow 80% of rated alternator output for the car audio system: 160A from a 200A alternator and 240A from a 300A alternator.
| Bank Capacity | Battery Only | + 200A Alternator | + 300A Alternator |
|---|---|---|---|
| 44Ah | ≈ 5,100W RMS | ≈ 7,000W RMS | ≈ 7,900W RMS |
| 88Ah | ≈ 10,300W RMS | ≈ 12,100W RMS | ≈ 13,100W RMS |
| 132Ah | ≈ 15,400W RMS | ≈ 17,300W RMS | ≈ 18,200W RMS |
| 176Ah | ≈ 20,600W RMS | ≈ 22,400W RMS | ≈ 23,400W RMS |
| 220Ah | ≈ 25,700W RMS | ≈ 27,600W RMS | ≈ 28,500W RMS |
Charging Voltage & Electrical System Compatibility
These EVE batteries use a 4S LiFePO4 configuration and are intended for conventional 12V class automotive charging systems.
Recommended vehicle charging range:
Approximately 13.4V – 14.6V
Maximum 4S LiFePO4 charging voltage:
14.6V
- Well suited to conventional 13-14V automotive electrical systems
- Compatible with upgraded high output alternators or factory alternators
- Provides strong usable capacity throughout the normal charging voltage range
Choosing the Correct EVE LiFePO4 Battery
- 44Ah: Compact high current bank for smaller high power systems or builds with strong alternator support.
- 88Ah: Increased current capability and reserve capacity for larger daily and demo systems.
- 132Ah: Strong option for serious multi kilowatt systems requiring considerably more electrical reserve.
- 176Ah: Large capacity bank for demanding demo systems and substantial amplifier loads.
- 220Ah: Maximum capacity configuration for extreme car audio electrical systems requiring very high current capability and reserve capacity.
A larger bank increases both maximum available current and the amount of stored energy available.
Real World Car Audio Applications
The EVE 22Ah LiFePO4 range is suited to:
- High RMS daily car audio systems
- Bass heavy music systems
- Demo vehicles
- Multiple amplifier installations
- Vehicles with high output alternators
- Systems suffering excessive voltage drop with conventional batteries
- Large lithium bank installations requiring additional reserve capacity.
