Extreme 270Ah TITANIUM 14.4V Battery Pack - 36 LTO Cells with BMS and Bars - 126x14x19cm

Ready to use: 14.4V Titanium Tit4nium® LTO battery pack consisting of 36 Extreme 45AH LTO cells, complete with BMS, aluminum bus bar, loaded and balanced.

The cells used are 2.4V and 45Ah each; connected in series and parallel, they form a 270Ah battery with nominal voltage of 14.4V, indicatively suitable for audio systems up to 24000-31000 WRMS.

The actual value depends on factors such as alternator charging capacity, distance between batteries and amplifiers, cross section and quality of wiring, and overall system configuration.

WEIGHT: about 40 kg.

DIMENSIONS: 126 x 14 × H 19 cm.

Why choose the new LTO 45AH Extreme cells?

This series differs markedly from classic LTO cells in superior performance and unique advantages:

  • Discharge up to 25C (vs. 10C for conventional LTOs)

  • Charge up to 15C (vs. 6C of traditional LTOs)

  • Rated voltage 14.4V (2.4V per cell x 6) compared to 13.8V of standard LTOs

  • Weight reduced by 30% (about 1000g per cell, instead of 1300g)

  • More compact size: reduced diameter by 5mm, reduced length by 10mm

  • More energy in less space

Due to these features, performance is on average 15-25% higher than that of standard LTOs, reaching up to 30% with charging at 15V or higher.

CAUTION: We do not recommend use with standard 14V alternators, as the rated voltage of this battery pack is 14.4V. For maximum performance, we recommend:

  • GS Alternators or others that have end-of-charge voltage 14.8V or higher (the optimum value for these cells is 15.2V)

  • Modification of your original alternator to achieve 14.8/15V end-of-charge voltage

CELL QUALITY AND CONTROL

GS Audio cells of GRADE A, selected and ultra-low internal resistance, with guaranteed values.

Inrush and internal resistance tests are documented in the quality control sheet included inside the battery pack.

CUSTOM ASSEMBLY AND SHIPPING

LTO Titanium battery packs are assembled to order and take up to 2 working days before shipping.

Lightweight batteries are packed reinforced with wood and Styrofoam, while batteries ≥25 kg are shipped on pallets in a custom-made wooden crate. Preparation may take 1 additional day.

LTO CHARACTERISTICS

Structure and characteristics of lithium titanate (LTO) batteries

Lithium titanate (LTO) batteries differ from classical lithium-ion batteries in the composition of the anode. In these cells, lithium titanate oxide (Li₂TiO₃) replaces graphite (carbon), typically used in conventional batteries. The cathode can be lithium manganese oxide (LMO) or lithium manganese cobalt oxide (NMC).

At the microscopic level, the LTO has a three-dimensional structure composed of lithium titanate nanocrystals. This configuration enables an operating voltage of 2.4 V, fast charging, and the ability to withstand discharge currents up to 10 times the rated capacity.

Benefits of LTO technology

One of the main strengths of lithium titanate batteries is the greater surface area available for electron passage. The anode has a surface area of about 100 m² per gram, compared with only 3 m² per gram in conventional 3.7 V lithium-ion batteries. This feature enables extremely fast recharging and a significantly longer service life. LTO batteries can be recharged in 6-10 minutes, compared with 8 hours required for standard rechargeable batteries, with a charging efficiency of more than 98%.

Safety and thermal stability

The lower operating voltage of 2.4 V offers significant advantages in terms of safety and environmental impact. The absence of carbon in LTO cells reduces the risk of thermal instability and overheating, eliminating a major cause of fires in conventional storage systems.

Independent tests conducted on LTO batteries show that, even in the event of a short circuit, the maximum temperature reached does not exceed 90-100 °C, without causing explosions or fires. This makes LTO batteries a much safer solution than LiPo (lithium-polymer) batteries.
