How long do lithium marine trolling motor batteries last?

Traditional lead-acid batteries typically last between 2 and 5 years and require regular maintenance, such as checking electrolyte levels and cleaning terminals. They are prone to environmental damage and can pose risks due to toxic leaks.In contrast, lithium LiFePO4 batteries present a maintenance-free option with no toxic components and a significantly longer lifespan, often exceeding 8 to 10 years. These batteries can endure thousands of charge cycles and are less impacted by deep discharges, although it's advisable to keep the discharge level around 80% for optimal performance. LiTime lithium marine batteries, for example, offer over 4000 life cycles at 100% depth of discharge (DOD) and can last more than a decadeProper storage is essential for all marine batteries, ideally at temperatures from 10°C to 35°C / 50'F to 95°F and away from extreme conditions. Regular cleaning and appropriate charging practices—avoiding overcharging or undercharging—are also crucial. For lead-acid batteries, using a trickle charger is recommended, while LiFePO4 batteries benefit from a built-in battery management system (BMS) to prevent charging issues.When selecting a marine battery, lithium batteries stand out due to their durability, efficiency, lightweight design, and eco-friendliness, despite a higher upfront cost. Ultimately, transitioning to lithium can offer long-term savings and convenience for boat owners.

What are the benefits of LiTime lithium marine trolling motor batteries compared to other lithium batteries?

LiTime lithium marine batteries feature a proprietary battery management system (BMS) designed to protect against moisture, dust, and salt spray, making them ideal for harsh marine environments. Additionally, all LiTime marine batteries comply with ABYC E-13 standards, ensuring the highest level of safety for your sailing needs.

What should you do when you get a new battery?

When you receive your battery, it may have a low state of charge (SOC) due to transportation and storage. To ensure optimal performance, charge the battery immediately to avoid over-discharge.Batteries with Bluetooth functionality may arrive in an off state, showing a terminal voltage between 3V and 5V, and you won't be able to connect them to your phone. This is because they are shipped powered off, similar to mobile phones, to minimize self-discharge and extend the battery's lifespan.There are 2 ways to solve the problem: using an AC-DC lithium battery charger or an MPPT solar charge controller to charge it for 3 to 10 seconds, then the battery can be used normally.If you plan to store the battery for a long time, charge it to a SOC of 50% and perform maintenance every three months. This will help preserve its functionality and performance.

What's the warranty of the LiTime lithium marine trolling motor batteries?

LiTime offers a 5-year warranty on our batteries. For more details, please visit LiTime Warranty Policy.

How to charge the LiTime LiFePO4 lithium marine batteries?

Because LiFePO4 lithium batteries have different charging requirements than lead-acid batteries, we recommend using a LiFePO4 lithium battery charger.Here are the charging options for LiTime lithium marine batteries:1. AC-DC Lithium Battery Charger: Select a charger with the appropriate voltage to safely charge the battery.2. Solar Panels: When using solar panels, always connect a solar charge controller to ensure safe charging.3. Alternator/Generator:DC Output: If your alternator or generator provides DC output, you will need a DC-to-DC charger to connect the battery.AC Output: If it provides AC output, use a compatible battery charger as specified in the product manual to safely connect the battery and generator.

Does LiTime provide marine starting batteries?

Yes, visit LiTime marine starting batteries for choice.

Can I connect LiTime lithium trollling motor batteries in series or parallel?

Yes, LiTime deep cycle lithium batteries can be connected in series and parallel.Note: To connect batteries in series or parallel, they must meet the following conditions:a. They should be identical batteries with the same capacity (Ah) and battery management system (BMS) rating (A).b. They must be from the same brand, as lithium batteries from different brands have unique BMS configurations.c. They should be purchased within a close timeframe (ideally within one month).

Are LiTime Trolling Motor Batteries waterproof?

Yes, LiTime lithium-ion marine batteries for deep cycle use are rated IP65 for waterproof protection. This means they are safeguarded against dust and water spray, making them suitable for marine environments. However, for long-term protection, it’s advisable to install the lithium-ion marine battery inside the cabin of the boat or in a battery box.

Are LiTime LiFePO4 Lithium batteries safe?

Yes. LiFePO4 is an inherently safe chemistry and the most stable lithium-type battery on the market. LiTime lithium cells are certificated by UL, FCC, CE, RoHS, and UN38.3 to ensure their quality and safety. All LiTime LiFePO4 batteries come with an internal Battery Management System, which protects against under-voltage during discharge, over-voltage during charge, over-current during discharge, over-temperature during charge and discharge, and short-circuit protection – protects battery cells from damage. Additionally, LiTime LiFePO4 Lithium batteries have been tested to be free from the risk of fire.

Is it OK to charge LiFePO4 to 100%?

Yes, LiTime LiFePO4 batteries can be charged to 100%. Unlike some other lithium battery chemistries, LiFePO4 batteries are designed to handle full charges without significant risk of damage. However, for optimal longevity, it’s often recommended to keep the battery's SOC between 20% and 80% for regular use.

Is it bad to completely drain a LiFePO4 battery?

It is not recommended to fully discharge LiFePO4 batteries. Although these batteries can handle deep discharges better than lead-acid batteries, frequently discharging them to 0% can reduce their lifespan and performance. It's best to recharge the battery before it drops below a very low level, ideally at 20% or higher.

Is it OK to leave a LiFePO4 battery on the charger?

Although it is generally safe to leave a LiFePO4 battery on the charger, as both the charger and the battery itself have protection mechanisms (for example the battery has BMS) to prevent overcharging, it’s still best to monitor the charging process. Once the battery is fully charged, disconnecting it promptly is recommended to avoid unnecessary damage. For convenience, LiTime offers chargers with Anderson connectors, allowing you to stop charging simply by unplugging the Anderson connector without needing to separate the battery terminals from the screws after charging. However, for optimal safety, it’s advised to first unplug the AC plug before disconnecting the Anderson connector.
