Description
The LTO Titanium Tit4nium® 14.4V 40Ah battery pack is designed for demanding high-power car audio installations. Composed of 12 GS Audio 20Ah prismatic cells, this pack offers double the capacity compared to the 20Ah model, to power very high-power amplifiers. Actual performance depends on the alternator's charging voltage, the distance between the batteries and the amplifiers, and the quality of the wiring.
- Recommended charging voltage: 14.4V to 15.8V
- If the alternator operates below 14.4V → reinforced alternator or 2.3V cylindrical LTO cells recommended

Why choose it?
- 40Ah capacity – double the 20Ah model – for demanding high-power systems (3,600–4,800 WRMS)
- LTO technology: lithium titanate oxide (Li₂TiO₃) anode – no risk of thermal instability
- Anodic surface 100 m²/g vs 3 m²/g for classic Li-Ion → ultra-fast charging (6–10 min), efficiency >98%
- Max short-circuit temperature: 90–100°C – no fire, no explosion
- GS Audio Grade A cells with guaranteed values and quality control sheet included
- Only global manufacturer of 20Ah prismatic LTO cells: Toshiba – beware of advertised higher capacities
