Bluetooth 5.0 Offers Smarter & More Connected Boating Experience
The advanced Bluetooth5.0 offers: auto-connection, smart discharging control, real-time battery monitoring, battery system checking. Stay informed and in control, ensuring your adventures are powered smoothly and efficiently.
Reliable Charging in Australia's Coldest Conditions
Designed to perform even in Australia’s cooler climates, the self-heating function ensures efficient charging when temperatures drop. When charging in cooler conditions, the power supply first activates the internal battery heating pad, warming the battery until it reaches 10°C (50°F), at which point heating automatically stops, and charging begins. The BMS-controlled self-heating function operates when charging between -20°C to 5°C (-4°F to 41°F), ensuring reliable charging and stable power backup in cold conditions. It efficiently brings the battery to the optimal temperature within 40-70 minutes from -10°C (14°F) and 80-120 minutes from -20°C (-4°F), providing consistent performance even in low-temperature environments.
Self-Developed BMS & EV-Grade LiFePO4 Cells for Marine Power
LiTime’s advanced BMS and EV-Grade LiFePO4 starting cells provide exceptional reliability for marine applications. Designed for peak performance, the upgraded BMS features 20+ protective functions, ensuring maximum safety and durability.

Whether you're navigating calm waters or challenging conditions, this battery offers long-lasting performance, peace of mind, and industry-leading innovation—ensuring your marine power is always secure.
No, this battery should not be used as a lithium cranking battery for 4WD/4×4 cars, motorcycles, tractors, or any other vehicles. It is specifically designed for marine applications, including fuel-powered outboard motors.
To ensure the best use of your battery, keep the following in mind:
● Cranking Battery – Designed for engine ignition, providing high Cold Cranking Amps (CCA) for a quick, powerful burst of energy to start fuel-powered motors. Not ideal for sustained power supply.
● Deep Cycle Battery – Built for long-term power supply, capable of deep discharge cycles but lacks the high cranking power needed to start an engine.
● Dual-Purpose Battery – A versatile option that combines both starting and deep cycle functions, making it suitable for boats requiring both engine ignition and power for onboard electronics as a dual battery system.
CCA (Cold Cranking Amps) and MCA (Marine Cranking Amps) are key indicators of a battery’s starting power.
● CCA (Cold Cranking Amps): Measures the current (in amps) a battery can provide for 30 seconds at -18°C (0°F) while maintaining a voltage of at least 7.2V. It is mainly used for vehicles operating in cold environments.
● MCA (Marine Cranking Amps): Similar to CCA, but measured at 0°C (32°F) instead. The test conditions are the same—sustaining the current for 30 seconds while keeping the voltage above 7.2V. MCA is specifically used for marine applications.
The only difference between CCA and MCA is the testing temperature. Both ratings help determine a battery’s ability to start an engine under different weather conditions.
LiTime's 12V 140Ah dual-purpose battery is tested at different temperatures and provides four cranking current values:
● CCA (-18°C)
● CCA (-10°C)
● MCA (0°C)
● HCA (25°C)
These values indicate the battery’s cranking performance at various ambient temperatures. LiTime defines these ratings based on the highest current the battery can sustain for 1 second at each temperature without triggering its built-in protection system.
Through extensive research on engine starting requirements, we found that in real-world applications, an engine typically requires a cranking current for only milliseconds. By testing at 1-second duration, we ensure the battery has ample power reserves, guaranteeing reliable engine starts.
Yes, but there are limitations based on the intended use:
1. For Starting & Deep Cycle Applications:
a. Supports up to 4 identical batteries connected in parallel.
b. Maximum configuration: 12V (12.8V) 560Ah battery system.
c. ⚠️ Only parallel connections are supported; series connections are not allowed.
2. For Energy Storage Applications:
a. Supports up to 16 identical batteriesin the following configurations:
i. 4 in series for a 48V (51.2V) system
ii. 4 in parallel for a 560Ah system
Before connecting batteries, ensure the following:
● They must be identical models with the same capacity (Ah) and BMS specifications (A).
● All batteries should be from the same brand to ensure BMS compatibility.
● Batteries should be purchased within the same period (within one month) for consistent performance.
Since batteries may arrive with a low State of Charge (SOC) due to shipping and storage, follow these steps:
1. Charge the battery immediately to prevent over-discharge and ensure optimal performance.
2. Use a LiFePO4 battery charger to fully charge the battery before first use.
3. Ensure the battery voltage is above 11.5V before attempting to start a motor.
4. Monitor via Bluetooth: The built-in Bluetooth function allows you to track the battery’s voltage and capacity when under load for an extended period. Ensure the voltage does not drop below 11.5V.
5. Starting Guidelines:Do not crank the motor for more than 3 seconds per attempt.
a. If the first attempt fails, wait 15 seconds before trying again.
b. If the motor fails after 3 attempts, inspect the system and wait 5 minutes before trying again.
🔹 For Bluetooth models:
Some batteries may arrive in anoff state, showing a virtual voltage of 3V-5V. This is normal. To activate:
● Use an AC-DC LiFePO4 charger or MPPT solar charge controller to charge for 3-10 seconds. This will wake the battery for normal operation.
🔹 For long-term storage:
● Charge the battery to 50% SOC before storage.
● Perform a maintenance charge every 3 months to preserve battery life.
