One Battery, Two Powers
— From Outboard Starts to Onboard Power
Tired of carrying two heavy batteries? Only one LiTime 12V 165Ah dual purpose lithium marine battery is born for two purposes. With 1200CCA, it reliably cranks fuel-powered outboard motors up to 300HP, even in cold conditions. With 2112Wh capacity and 4000+ cycles, it keeps your fish finder, trolling motor, lights, and other onboard electronics running without worry.
Reliable Starts Even in the Cold
No more weak cranking or slow starts. With 1200 CCA at 14°F and 1300 MCA at 32°F, LiTime 12V 165Ah dual-purpose marine battery delivers instant, confident engine starts in any weather. Whether you’re running a Mercury, Honda, Suzuki, Evinrude, or Tohatsu outboard, you’ll have the power you need to fire up quickly and head out without worry.
Smart Bluetooth Made Monitoring with Ease
Check battery status, switch on, or manage discharge directly from your phone. Manage 25% emergency reserve or emergency discharge with one tap. Plus, with the newest OTA upgrades, LiTime 12V 165Ah dual purpose lithium battery always stays updated with the latest LiTime BMS features.
Upgrade to 12V 165Ah for Stronger Power
LiTime 12V 165Ah dual purpose lithium battery takes performance to the next level. With 1200CCA@14℉(vs. 1000CCA), 150A BMS (vs. 140A), and 2112Wh energy (vs. 1792Wh), it upgrades from 140ah at smoother engine starts, more reliable power for your electronics, and extended runtime on every trip.
Compact Design, Maximum Capacity
LiTime 12V 165Ah dual purpose lithium battery delivers 76% more energy (2112Wh) while saving 50% space and cutting 75% weight compared to two 12V 100Ah lead-acid. Enjoy easier installation, more storage room, and longer runtime—all in the compact Group 31 size.
IP67 Protection, Marine-Grade Confidence
LiTime 12V 165Ah dual purpose lithium battery comes with IP67 protection—water-proof, dust-proof, and salt-spray-proof. Whether you’re navigating rough seas, fishing in saltwater, or docking along the coast, it provides reliable performance and long-lasting durability in the harshest marine environments.
Built for Safety, Proven to Last
LiTime 12V 165Ah dual purpose marine battery features self-developed BMS with 20+ smart protections—guarding against overcharge, over-discharge, overcurrent, overheating, and short circuits. Upgraded with low-temp cut-off, moisture and salt-spray resistance, plus 30s auto-recovery from overload, it ensures dependable performance even in harsh environments.
One Battery Does It All
LiTime 12V 165Ah dual purpose lithium marine battery lets you crank your outboard with confidence and power your onboard electronics all day—lights, radar, fish finder, and more. One battery, no extra hassle.
4 Charging Methods
Whether you use LiFePO4 battery charger, outboard alternator, generator, or solar panel, you can fully charge your battery efficiently and reliably.
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.
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.
