| Parameter | Specification |
|---|---|
| Energy Capacity | 1280Wh |
| Cycle Life | 3,000+ cycles |
| Weight | 24.25 lbs |
| Operating Temperature | -4°F to 140°F |
How Does the LiTime 12V 100Ah Compare to Lead-Acid Batteries?
Unlike lead-acid batteries, the LiTime LiFePO4 battery offers 4x longer lifespan, 50% weight reduction, and 95% usable capacity. It charges 3x faster, maintains consistent voltage during discharge, and requires zero maintenance. Lead-acid batteries degrade faster under deep discharges, while LiFePO4 chemistry ensures stable performance even at 100% depth of discharge.
What Applications Is the LiTime 12V 100Ah Battery Best Suited For?
This battery excels in solar energy storage, RV/camper power systems, marine trolling motors, off-grid cabins, and electric vehicles. Its compact size and lightweight design make it ideal for mobile applications, while its high discharge rate supports power-hungry devices like inverters, refrigerators, and medical equipment.
For solar installations, the battery’s 1280Wh capacity can store enough energy to power a medium-sized cabin for 24 hours. Marine enthusiasts appreciate its vibration resistance and ability to run fishfinders/GPS systems continuously for 18+ hours. RV users benefit from silent operation and the ability to recharge via solar panels while boondocking. Unlike traditional batteries, it maintains full capacity even when partially charged, making it perfect for irregular charging scenarios common in renewable energy systems.
How Do You Properly Charge a LiTime 12V 100Ah LiFePO4 Battery?
Use a LiFePO4-compatible charger with 14.4–14.6V absorption voltage and 13.6–13.8V float voltage. Avoid charging below 32°F. The BMS automatically cuts off at 14.6V to prevent overcharging. A 100Ah battery typically charges in 4–5 hours with a 20A charger. For solar setups, pair with a 30A MPPT charge controller.
What Safety Features Does the LiTime 12V 100Ah Battery Include?
The battery’s BMS provides overcharge, over-discharge, overcurrent, short-circuit, and temperature protection. LiFePO4 chemistry is inherently non-combustible, unlike lithium-ion. The rugged ABS case resists impacts, vibrations, and corrosion, making it suitable for harsh environments.
How Does Temperature Affect the LiTime 12V 100Ah Battery’s Performance?
Performance drops at temperatures below -4°F, with charging disabled by the BMS. At 140°F, capacity reduces by 15–20%. Optimal operation occurs between 32°F–95°F. For cold climates, insulated battery boxes or self-heating models are recommended.
In sub-freezing conditions, the BMS actively monitors cell temperatures to prevent lithium plating during charging. Users in desert environments should provide shade or active cooling when temperatures exceed 110°F. The table below shows capacity retention at various temperatures:
| Temperature | Capacity Retention |
|---|---|
| 32°F | 95% |
| 77°F | 100% |
| 104°F | 92% |
| 140°F | 80% |
“LiTime’s 12V 100Ah battery represents a paradigm shift in energy storage. Its use of automotive-grade LiFePO4 cells and multi-layer BMS architecture ensures reliability unmatched in its price range. For users transitioning from lead-acid, this battery reduces long-term costs by 60% while delivering superior performance in renewable energy systems.” — John Carter, Renewable Energy Systems Engineer
FAQ
