Stealth Energy Lithium Titanate Battery 13.8V 40Ah

The Stealth Energy Lithium Titanate Battery 13.8V 40Ah from American Bass USA is a high-current power source built for demanding car audio systems, delivering sustained voltage and rapid current delivery for serious listening setups.

• Nominal Voltage: 13.8V — designed to interface with automotive electrical systems and maintain stable voltage under load.
• Nominal Capacity: 40Ah — provides substantial energy for extended playback and amplifier demands.
• Cell inside: LTO Cylindrical cell 66160 2.3V 40AH — lithium titanate chemistry known for high current capability and long life.
• Configuration: 6S1P — six cells in series with a single parallel string for a compact high-current pack.
• Continuous Discharge Current: 400A (10C) — supports sustained high-current draw without voltage collapse.
• Peak Discharge Current: 800A (20C) — handles brief current spikes during demanding musical passages or transient bass.
• Discharge Cut-off Voltage: 9V (1.5V per cell) — protects cells from excessive discharge for longevity.
• Charge Cut-off Voltage: 16.8V (2.8V per cell) — protects cells during charging to maintain cell health.
• Balancing Start Voltage: 2.7V per cell (adjustable between 2.5V ~2.8V) — enables cell balancing control to preserve balance and capacity over time.
• Battery Net Weight: 15.6 Kg (approx.) — substantial mass reflects robust construction for high-current performance.
• Battery Dimension: 14.2'' (L) × 10.1'' (W) × 9.3'' (H) / 360 × 255 × 235 mm — compact footprint suitable for tight install spaces.
• Connector: Pair of 3-hole aluminum blocks — provides a safe, reliable connection to high-current wiring.
• Operating temperature: Charging 0°C–45°C; Discharging -20°C–55°C — wide temperature range supports varied vehicle climates and usage.
• Storage temperature: 20 ± 5°C — recommended conditions to maximize long-term storage life.
• Life Cycle: >20,000 cycles (80% of initial capacity at 1C rate, IEC Standard) — durable performance suitable for long-term installations.

In a car audio build, this battery provides the high current bursts and long cycle life needed for multi-amp systems or demanding sub setups, keeping voltage steady during bass-heavy passages while offering longevity and a compact, install-friendly form factor.
