12V 100Ah Lithium Marine Battery

Extended Cycle Life: Offers 3,000–4,000+ cycles at 80% depth of discharge (DoD), outperforming lead-acid batteries (typically 300–500 cycles).

High Energy Density: Provides 1280Wh energy in a compact design, ideal for space-constrained installations.

Lightweight & Portable: Weighs 14.7–18 kg, approximately 1/3 the weight of equivalent lead-acid batteries (30–50 kg).

Advanced Safety: Built-in Battery Management System (BMS) prevents overcharge, over-discharge, short circuits, and thermal runaway.

Wide Temperature Range: Operates in -20°C to 60°C, ensuring reliability in extreme climates.

Low Self-Discharge: ≤3% monthly loss, reducing maintenance needs compared to lead-acid batteries (5–20% monthly).

Primary Applications

Renewable Energy Storage: Powers solar/wind systems and off-grid homes, delivering stable energy for lighting, appliances, and HVAC.

Transportation: Used in RVs, marine vessels (trolling motors, navigation systems), and electric vehicles (golf carts, scooters) for long-lasting, maintenance-free operation.

Industrial Equipment: Supports AGVs, forklifts, and heavy-duty tools with high discharge efficiency (up to 100A continuous current).

Emergency Backup: Ensures uninterrupted power for telecom towers, medical devices, and critical infrastructure during outages.

Advantages Over Lead-Acid Batteries

Cost Efficiency: Longer lifespan reduces replacement frequency, lowering total ownership costs by 50–70%.

Fast Charging: Supports 0.5C–1C charging rates (e.g., 50–100A), cutting downtime versus lead-acid’s slow absorption charging.

Eco-Friendly: Non-toxic LiFePO4 chemistry avoids lead pollution and complies with RoHS standards.

Installation Flexibility: IP54-rated casing allows vertical/horizontal mounting without acid leakage risks.
