1000CCA Instant Cold Cranking: High-discharge LiFePO4 chemistry delivers 1000A peak current (3-5s) down to -20°C, solving cold-weather starting failure.
60% Weight Reduction vs. AGM: Weighing just 16kg with 1920Wh capacity, it reduces vehicle front-end load while maintaining a stable 12.8V power rail.
Integrated High-Current BMS: Engine-grade active safety system prevents over-discharge, short circuits, and thermal runaway under heavy alternator stress.
When starting a high-displacement gasoline or diesel engine, the starter motor draws an immense instantaneous surge current—often exceeding several hundred amperes within milliseconds. Traditional lead-acid or AGM batteries suffer from high internal resistance, leading to drastic voltage drops that cause sluggish cranking, especially in cold winter conditions (-20°C). The HiMAXBATT 12.8V 150Ah LiFePO4 Automotive Starter Battery solves this fundamentally through high-rate Lithium Iron Phosphate cell architecture. Featuring an ultra-low internal resistance of ≤8 mΩ at 50% SOC, this battery maintains a flat discharge curve, effortlessly supplying 1000A peak current (3–5 seconds) to spin heavy starters rapidly. Engineered in a standard SAE-post layout (POS φ19mm, NEG φ17mm) and a robust 398×175×190 mm ABS casing, it drops seamlessly into standard engine bays while shedding over 60% weight compared to 150Ah AGM counterparts.
🛡️ Automotive-Grade Thermal Resilience & Advanced Protection Systems
Under-hood environments place extreme physical and thermal strain on energy storage systems. To withstand engine bay heat, continuous vibration, and moisture ingress, the HiMAXBATT starter battery is housed in an IP67 dust- and water-resistant ABS enclosure with reinforced cell mounting structures. Inside, a dedicated High-Current Battery Management System (BMS) actively monitors voltage, current, and temperature, featuring an automatic high-temperature safety cut-off at 75°C (167°F) with auto-reconnect at 50°C (122°F). Manufactured under rigorous ISO9001 quality management and UN38.3 transport safety protocols, every production unit undergoes rigorous thermal shock, mechanical vibration, short-circuit, and high-rate pulse discharge laboratory testing. This ensures full compliance with international automotive electrical standards, giving fleet operators and automotive technicians total peace of mind.

Frequently Asked Questions
Selecting the correct lithium starter battery requires understanding cold cranking amps, alternator charging characteristics, and engine compartment environment requirements. Here are technical answers to common questions asked by fleet mechanics, automotive engineers, and B2B buyers.
Can the HiMAXBATT 12.8V 150Ah LiFePO4 battery directly replace my vehicle's 12V AGM or Lead-Acid starter battery?
Yes. It features standard SAE automotive brass posts (POS φ19mm, NEG φ17mm) and a standard DIN-type ABS casing (398×175×190 mm). Its 12.8V nominal voltage aligns perfectly with standard 12V vehicle alternators (14.0V–14.6V charging voltage), requiring no modification to your vehicle’s alternator or starter motor.
How does a 1000CCA rating perform in extreme freezing temperatures down to -20°C?
Cold Cranking Amperage (CCA) measures the current output at -20°C (-4°F). Thanks to low internal resistance (≤8 mΩ) and optimized electrolyte formulation, HiMAXBATT delivers 1000A cranking current for 3–5 seconds down to -20°C, maintaining line voltage above 10V during ignition, preventing engine turnover hesitation.
Will the onboard vehicle alternator overcharge or damage the internal BMS during high-current charging?
No. The battery’s internal BMS is specifically tuned for automotive starting applications. It accepts up to 150A max charge current (recommended 30A) and incorporates BMS Charge Cut-Off at 14.6V (3.65V per cell) with balancing at 13.6V. It safely absorbs alternator pulses while protecting cells against overvoltage.
How does a 150Ah lithium starter battery benefit commercial vehicles and marine engines?
Beyond delivering 1000CCA cranking power, the 1920Wh reserve capacity powers auxiliary loads (inverters, pumps, onboard electronics, winch systems) during engine idle without rapid voltage decay. Additionally, at 16kg, it reduces front-end chassis weight by over 25–30kg compared to equivalent lead-acid systems.
What is the lifespan of HiMAXBATT LiFePO4 starter battery compared to traditional lead-acid batteries?
Conventional starter batteries achieve 300–500 cycles under shallow discharge. HiMAXBATT provides 2,000 cycles at 80% DOD (0.5C rate) and extremely low self-discharge (<3% per month). This translates to an operational service life 3 to 5 times longer than AGM batteries under equivalent starter-service conditions.
