Hot LiTime 12V 165Ah 1200 CCA Dual Purpose Marine Lithium Battery | Bluetooth & Auto Heating

LiTime lithium starting batteries are equipped with a built-in smart Battery Management System (BMS) that limits the charging voltage to 15V or below, ensuring safe and stable operation of the battery cells.

In most cases, outboard motor charging systems are fully compatible with LiTime lithium starting batteries and can charge and operate normally.

However, a small number of outboard engines with special regulator models may not match lithium batteries properly.

If this occurs, there are two recommended solutions:

1. Replace the voltage regulator with one that is compatible with lithium batteries.
2. Continue using a lead-acid starting battery.

Important: Please DO NOT use this battery as a starter battery for any type of vehicle, including cars, motorcycles, tractors, etc.

For optimal use of the battery, please observe the following safety precautions:

1. Engine Compatibility: Not compatible with the outboard motor without a built-in regulator, or older voltage regulators.

2. Mounting Requirements: When using in marine starting equipment (such as fuel outboard engines) or in vibrating environments, ensure the battery is securely mounted. It should not be used in areas with severe vibrations, such as tractors.

3. Secure Fastening: Ensure the battery is fastened securely when used with outboard engines or in unstable environments to prevent damage from movement.

4. Cable Length Considerations: Position the battery as close to the outboard motor as possible, as varying cable lengths can result in voltage loss. If the voltage drop exceeds this range, reduce the total cable length.

Yes. With 1200 CCA @14°F and 1300 MCA @32°F, it can reliably crank outboard motors up to 300HP, including Mercury, Honda, Suzuki, Evinrude, and Tohatsu. Before purchasing, check that your motor's required CCA is ≤1200A. If you're unsure, share your motor's CCA/MCA requirements and alternator charging current, and we'll help confirm compatibility.

Use a 14.4V 10A LiFePO4 charger. For easier BMS recovery after deep discharge, a charger with activation support is recommended.

Yes, you can connect the battery in series and parallel. But here are some limitations to follow:

1. For Starting and Deep Cycle:

Support connecting up to 4 identical batteries in parallel for up to:12V(12.8V) 660Ah battery system.

Note: It can only be connected in parallel instead of a series connection.

2. For ONLY Energy Storage:

Support connecting up to 16 identical batteries for up to: 4 in series as a 48V (51.2V) battery system or 4 in parallel as a 660Ah battery system.

To connect in series or parallel, batteries should meet the following conditions:

a. identical batteries with the same battery capacity (Ah) and BMS (A);

b. from the same brand (as lithium batteries from different brands have their special BMS);

c. purchased in near time (within one month).

1. Charge before first use: The battery may arrive with low SOC due to shipping/storage. Fully charge it with a LiFePO4 charger before use to avoid over-discharge.

2. Starting requirements: Battery voltage must be above 11.5V to start a motor. Each start should not exceed 3 seconds; if it fails, wait 15 seconds before retrying. After 3 failed attempts, wait 5 minutes and check for other causes.

3. Bluetooth activation: Some Bluetooth batteries may arrive “off,” showing 3–5V. This is normal. Simply connect to an AC-DC LiFePO4 charger or MPPT solar controller for 3–10 seconds to activate.

4. Storage tips: For long-term storage, charge to 50% SOC and recharge every 3 months to maintain performance.

Yes. The 12V 165Ah marine starting battery is rated IP67 waterproof and dustproof. However, it should not be fully submerged in bilge water. For added protection, we recommend installing it in a waterproof battery box or mounting it in an elevated or sheltered position such as inside the cabin.
