The Timeusb 12.8V 100Ah Low-Temp LiFePO4 battery (1280Wh, 100A BMS) is a high-tech solution for stable, safe, and long-lasting power for electrical equipment in off-grid environments, on the water, in campers, RVs, and solar power systems. Specifically designed for trolling motors, marine applications, and mobile power systems, this battery combines compact size, high capacity, a powerful BMS, and advanced protection features, particularly against low temperatures. Using Grade A prismatic LiFePO4 cells, the battery delivers significantly longer life than lead-acid batteries and maintains a stable voltage even under heavy loads. This makes the Timeusb 12.8V 100Ah ideal for users seeking an energy-efficient and reliable power source with minimal maintenance. Lithium iron phosphate chemistry (LiFePO4) is considered one of the safest of all lithium technologies. It is not subject to thermal runaway, does not emit hazardous gases, and is resistant to deep discharges. Advantages of LiFePO4 in the Timeusb 12.8V 100Ah: High chemical stability, Resistance to overheating, Minimal degradation over time, Full usable capacity without "memory effect." Battery life: 4,000 cycles at 100% depth of discharge (DOD), 6,000 cycles at 80% DOD. The Timeusb 12.8V 100Ah has a nominal voltage of 12.8 V and a capacity of 100 Ah, which corresponds to an energy reserve of 1280 Wh. This rating allows it to power a wide range of devices: Maximum continuous power of 1280 W, and peak discharge current reaches 500 A for 1 second, which is important for starting equipment with high starting currents. Powerful 100A BMS – intelligent monitoring The built-in 100 A battery management system (BMS) acts as the "brain" of the battery and continuously monitors: the voltage of each cell, the overall battery voltage, the charge and discharge current, and the temperature. The BMS provides protection against: overcharge, deep discharge, overcurrent, short circuit, and overheating. An additional advantage is the self-healing function: if the battery shuts down due to overload, it automatically resumes operation approximately 30 seconds after conditions return to normal. Low-Temp Protection: This model features intelligent protection against recharging at sub-zero temperatures: Charging is blocked at 0°C, and charging is automatically restored at +5°C. This significantly extends battery life when used in winter or cold regions, and also makes the battery safer for seasonal storage. IP65 Water Resistance – Ready for Marine Conditions. The battery case has an IP65 protection rating, which means: Complete dust protection, and protection against water jets from any direction. The battery's dimensions, 260 x 168 x 210 mm, comply with the Group 31 standard. This means the battery can be installed without any modifications in place of a traditional lead-acid battery of the same format. TimeUSB supports the connection of up to 4 batteries in parallel and up to 4 batteries in series in a 4P4S configuration. The maximum system capacity can reach 20.48 kWh, opening the possibility of creating fully autonomous power systems for a home, workshop, camper, or boat. Wide temperature range: Charging: from 0°C to +50°C; Discharging: from -20°C to +60°C; Storage: from -10°C to +50°C. This allows the battery to be used in both hot summer and cold weather.
