What Is an LTO Battery? Why Lithium Titanate Beats LiFePO4 in Cold and Cycle Life
This 12V 40Ah LTO battery pack is built from six genuine Yinlong 66160H lithium titanate cells (2.3V / 40Ah each) with a HELTEC balancer in a transparent acrylic case. Unlike LiFePO4, this lithium titanate battery charges at -30°C, discharges at -50°C, and delivers 25,000+ cycles — roughly 25 times the service life of a lead-acid battery. Shipped from our EU warehouse with DDP tax-free delivery in 5–9 days.

FAQ
- Can an LTO battery replace my lead-acid starter battery? — Yes for cranking: 6S LTO holds >11V at 600A where lead-acid collapses below 9.5V. Set your charger to 17.4V.
- Can I charge LTO in winter? — Yes. LiFePO4 BMS blocks charging below 0°C; this pack charges down to -30°C.
- How long does a 25,000-cycle battery last? — One full cycle per day ≈ 68 years of calendar life; the chemistry outlives typical equipment.
- Is this pack new or refurbished? — Brand-new A-grade Yinlong 66160H cells with batch test reports available on request.
- What can I power with 480Wh? — Solar storage for cabins, car audio competition systems, boat trolling/starting, camper backup, diesel heater + lighting off-grid.
