What Are the Key Technical Specifications of This Solar Battery?
Key specs include: 12.8V nominal voltage, 1280Wh energy capacity, ±0.1V voltage consistency between cells. Charge voltage: 14.4-14.6V, discharge cutoff: 10V. Operates at 95% efficiency with ≤3% self-discharge monthly. Compatible with 100-450W solar panels and most charge controllers. Includes M8 terminal connectors and IP65 waterproof rating for outdoor installations.
| Parameter | ECO WORTHY Lithium | Standard Lead-Acid |
|---|---|---|
| Cycle Life | 4,000+ cycles | 500-800 cycles |
| Weight | 24 lbs | 68 lbs |
| Charge Time | 2.5 hours | 8+ hours |
The advanced Battery Management System (BMS) continuously monitors cell voltages with ±0.5% accuracy, enabling safe 0.5C fast charging (50A maximum). Unlike lead-acid batteries that lose capacity in partial state of charge (PSOC) conditions, this LiFePO4 battery maintains full capacity even when regularly discharged to 50%. Its low self-discharge rate makes it ideal for seasonal use, losing only 3% charge monthly versus 15-30% in lead-acid alternatives.

What Safety Features Protect the ECO WORTHY Lithium Battery?
Seven-layer protection includes: Overcharge (＞14.6V cutoff), over-discharge (＜10V cutoff), short circuit (0.01ms response), overcurrent (＞150A disconnect), overtemperature (158°F shutdown), reverse polarity protection, and cell balancing (±20mV accuracy). UL1973 certified with explosion-proof aluminum casing and flame-retardant electrolytes.
| Protection Feature | Activation Threshold | Response Time |
|---|---|---|
| Overcharge | 14.6V | 2ms |
| Short Circuit | 0Ω resistance | 0.01ms |
| Overcurrent | 150A | 50ms |
The multi-stage safety system incorporates both hardware and software safeguards. The ceramic separator between cells prevents thermal runaway, while the vented aluminum casing withstands internal pressures up to 300 psi. During testing, the battery showed zero combustion risk when punctured or exposed to open flames. The dual-path thermal management system combines passive cooling fins with active fan-assisted ventilation during high-load scenarios.
“The ECO WORTHY 100AH sets a new benchmark for budget-friendly lithium storage. Its true innovation lies in the hybrid BMS that combines active balancing with passive protection – something usually seen in batteries costing twice as much. The 0.5C fast charge acceptance (50A) is particularly impressive for off-grid scenarios with limited charging windows.” – Solar Storage Analyst, RenewableTech Quarterly
FAQs
- How long does shipping take for ECO WORTHY batteries?
- Standard delivery takes 5-7 business days within continental US via UPS Ground. Batteries ship pre-charged to 30% capacity with all necessary terminals and mounting hardware included.
- Does warranty cover solar system compatibility issues?
- The 5-year limited warranty excludes damage from improper charging (＞14.6V input) but covers BMS failures and capacity degradation below 70% within 3,000 cycles. ECO WORTHY provides free compatibility checks for your specific solar setup upon request.
- Can I connect these batteries to existing lead-acid systems?
- Not recommended. Mixed chemistry systems cause unbalanced charging. For hybrid setups, use separate charge controllers and DC-DC converters. ECO WORTHY sells dedicated lithium-to-lead-acid combiners ($89) that prevent back-feeding while enabling shared load distribution.
