# Meet Our 12V LTO Battery Pack with Heltec Monitoring — Built for Extreme Durability
Looking for a rechargeable battery that can handle countless charge cycles, freezing temperatures and heavy-duty use? Our 12V Lithium Titanate Oxide (LTO) battery pack is engineered for reliability, available in 30Ah, 35Ah and 40Ah capacity options, equipped with a Heltec module for precise real-time battery monitoring.
LTO technology is well-known in the energy storage industry for its incredible longevity. Compared with LiFePO4 batteries, LTO cells deliver far more charge-discharge cycles, often exceeding 10,000 cycles. They retain great capacity at sub-zero temperatures, support rapid charging, and feature superior safety tolerance against abuse. That makes LTO a top pick for cold-region installations, frequent cycling applications and mission-critical backup power.
This demo unit is assembled with 2.3V cylindrical LTO cells, housed in a clear acrylic enclosure. The transparent design lets you inspect the internal wiring, busbars and cell layout directly, ideal for demonstrations, lab testing and DIY education. The integrated Heltec module brings smart monitoring to the system: it continuously tracks individual cell voltages, pack temperature, SOC, and supports data communication. You can pull live battery status remotely and catch potential imbalance issues early to protect your battery investment.
