EcoWorthy 12V 100Ah LiFePO4 Battery

The EcoWorthy 12V 100Ah LiFePO4 battery excels in solar energy storage due to its high efficiency (95%+), 3,000+ cycle life, and lightweight design. Its built-in Battery Management System (BMS) prevents overcharge/over-discharge, ensuring compatibility with solar inverters. Ideal for off-grid setups, it outperforms lead-acid batteries with faster charging and deeper discharge capabilities (100% DoD).

How to Prevent Lithium-Ion Battery Fires and Explosions

How Does the LiFePO4 Chemistry Enhance Solar Energy Storage?

Lithium Iron Phosphate (LiFePO4) chemistry offers thermal stability, reducing fire risks compared to lithium-ion. It maintains consistent voltage during discharge, minimizing energy loss. With a lifespan of 8-10 years, it resists degradation even in high-temperature environments, making it reliable for solar applications. Its 100% depth of discharge (DoD) doubles usable capacity versus lead-acid’s 50% limit.

What Are the Key Specifications of the EcoWorthy 12V 100Ah Battery?

Weight	24.2 lbs (11 kg)
Charging Temperature	32°F–140°F (0°C–60°C)
BMS Protection	Overvoltage, undervoltage, short-circuit, overheating

Why Choose LiFePO4 Over Traditional Lead-Acid Batteries?

LiFePO4 batteries provide 3x longer lifespan, 50% lighter weight, and 2x faster charging than lead-acid. They require zero maintenance, unlike flooded lead-acid’s water refilling needs. With 100% DoD, they deliver full capacity versus lead-acid’s 50% usable limit. Even at higher upfront costs ($500–$800), their lifetime ROI surpasses lead-acid due to reduced replacement frequency.

How to Install the EcoWorthy Battery in a Solar Power System?

1. Mount vertically in a dry, ventilated area.
2. Connect to a solar charge controller (30A–50A MPPT recommended).
3. Use 4AWG copper cables for terminals to minimize resistance.
4. Set charge controller to LiFePO4 mode (14.2V–14.6V absorption, 13.6V float).
5. Test system voltage with a multimeter post-installation.

What Maintenance Practices Prolong the Battery’s Lifespan?

LiFePO4 batteries require minimal maintenance:

• Store at 50% charge if unused for >3 months
• Clean terminals annually with a brass brush
• Avoid discharging below 10.8V (BMS auto-cutoff at 10V)
• Update charge controller firmware for optimal voltage curves

To maximize longevity, monitor ambient temperature during seasonal changes. Batteries stored in freezing conditions should be disconnected and moved to climate-controlled spaces. For systems in humid coastal areas, apply anti-corrosion gel to terminals after cleaning. Modern charge controllers often include maintenance alerts—enable these notifications to track firmware updates and voltage calibration schedules. Periodic capacity testing (every 6-12 months) using a load tester helps identify early signs of cell imbalance.

How Does Temperature Impact Performance and Safety?

The EcoWorthy battery operates at -4°F–140°F (-20°C–60°C) but charges optimally at 32°F–113°F (0°C–45°C). Below freezing, internal heaters (optional) prevent lithium plating. Above 140°F, BMS disconnects to avoid thermal runaway. In solar setups, install shaded or insulated enclosures in extreme climates.

In desert environments, battery enclosures should incorporate reflective surfaces and passive ventilation slots. Arctic installations benefit from insulated boxes with silicone heating pads to maintain optimal operating temperatures. The BMS dynamically adjusts charge rates—slowing by 20% at 113°F and stopping completely at 140°F. Field tests show capacity retention remains above 95% after 500 cycles in controlled 77°F environments, compared to 88% retention in consistently hot (95°F) conditions.

Can This Battery Be Used in Parallel or Series Configurations?

Up to 4 EcoWorthy 12V batteries can be wired in parallel for increased capacity (400Ah max). Series connections are not recommended due to BMS incompatibility. For 24V/48V systems, use purpose-built 24V LiFePO4 batteries. Parallel setups require identical batteries and balanced cabling to prevent uneven load distribution.

What Solar Inverters Are Compatible?

Compatible inverters include:

• Renogy 2000W Pure Sine Wave (supports LiFePO4 voltage curves)
• Victron Energy MultiPlus-II (programmable for 12.8V systems)
• Giandel 1200W (auto-detects battery type)

Avoid modified sine wave inverters, which reduce efficiency by 15%–20%.

How Does Cost Compare to Other Solar Batteries?

Metric	EcoWorthy LiFePO4	AGM Equivalent
Upfront Cost	$649	$300–$400
Lifetime Cycles	3,000	1,200
Total Energy Storage	384,000Wh	72,000Wh
Cost per kWh	$0.08	$0.22

FAQ

Does it include a warranty?

Yes—5-year limited warranty, covering defects and premature capacity loss below 70% within 3 years.

Can it power a 1000W inverter?

Safely supports up to 1200W (100A discharge). For sustained 1000W loads, pair two batteries in parallel.

Is it compatible with Tesla Powerwall hybrid systems?

No—Tesla’s proprietary DC coupling conflicts with 12V systems. Use EcoWorthy’s 48V models for hybrid integration.
