Featured Snippet Answer: The 150Ah Lithium Battery Pack is designed for solar energy and electric vehicles, featuring a 30A BMS for safety, multi-voltage compatibility (12V/24V/29V), and a 12.6V charger. Its high energy density (150Ah) ensures prolonged power storage, while the Li-ion chemistry supports 2,000+ cycles, making it 50% lighter than lead-acid alternatives.
What Is a DC to DC Lithium Battery Charger and How Does It Work
How Does the Built-in 30A BMS Enhance Battery Safety?
The 30A Battery Management System (BMS) prevents overcharge, over-discharge, and short circuits. It balances cell voltages, maintains temperature stability, and extends lifespan by 30% compared to unprotected systems. For example, if voltage exceeds 29.4V, the BMS automatically disconnects the load, ensuring compliance with UL and CE safety standards.
Advanced BMS algorithms monitor individual cell voltages every 0.5 seconds, enabling precise balancing across all 8 cells in the 24V configuration. This prevents capacity fade caused by voltage mismatches. The system also includes layered thermal management—when internal temperatures reach 65°C, the BMS reduces charging current by 50% and triggers cooling fans. Field tests show this reduces thermal stress by 40% compared to passive cooling systems. For industrial applications, the 30A continuous discharge rating supports high-power tools like solar-powered water pumps without voltage drops.

Why Choose Li-ion Chemistry Over Traditional Lead-Acid Batteries?
Li-ion batteries offer 3x higher energy density, 50% weight reduction, and 80% depth of discharge (vs. 50% for lead-acid). They operate efficiently in -20°C to 60°C environments and charge 2x faster. A 150Ah Li-ion battery delivers 12kW continuous power, whereas lead-acid equivalents struggle beyond 5kW due to voltage sag.

What Solar Energy Systems Are Compatible With This Battery?
This battery integrates with 12V/24V/48V solar setups using MPPT charge controllers (30A–100A). It supports 3,000W inverters and pairs with 400W–1,200W solar panels. For a 24V system, 6x 400W panels generate 9.6kWh daily—sufficient to fully charge the 150Ah battery (3.6kWh capacity) in 4–5 sun hours.
When configuring hybrid systems, the battery seamlessly switches between solar input and grid power. Its 29V maximum charge voltage aligns with most MPPT controllers’ boost capabilities. Users report 94% round-trip efficiency when paired with 60A controllers, compared to 85% efficiency in lead-acid setups. For large installations, parallel connections allow scaling up to 48V/600Ah systems using four batteries—ideal for powering entire off-grid homes with 10kWh+ daily consumption.
| Solar Component | Compatibility Specification |
|---|---|
| MPPT Controllers | 30A-100A @ 12V-48V |
| Inverters | Pure sine wave up to 3,000W |
| Solar Panels | Voc ≤45V per string |
How Does the 12.6V Charger Optimize Recharge Efficiency?
The included 12.6V charger uses CC-CV (Constant Current-Constant Voltage) charging, reducing recharge time to 4 hours (0%–100%). It adjusts input from 100V–240V AC to 14.6V DC output, achieving 92% efficiency. A 10A charging current prevents overheating, while reverse-polarity protection safeguards against wiring errors.
Can This Battery Power Off-Grid Electric Vehicles?
Yes. The 29V configuration supports golf carts, e-bikes, and drones requiring 1,000W–3,000W motors. With a 150Ah capacity, it provides 4.35kWh energy—enough for a 50km EV range. The modular design allows parallel connections for up to 600Ah (17.4kWh), ideal for RVs and marine applications.
What Certifications Ensure Reliability and Safety?
Certified to UN38.3 (transport), IEC 62619 (industrial use), and RoHS (hazardous substance control), this battery meets global safety benchmarks. The IP65-rated casing protects against dust and water jets, while UL-recognized cells undergo 200+ quality tests, including nail penetration and thermal shock resistance.
How to Maintain Peak Performance Over 2,000 Cycles?
Avoid discharging below 20% SOC (State of Charge) and store at 50% SOC in 15°C–25°C environments. Recalibrate the BMS every 6 months by fully discharging/charging. Use torque-limiting tools to secure terminals at 4–6 N·m, preventing loose connections that cause voltage drops.
