A Game-Changer With Both Power $ Lightness

Trolling motors can easily glide and maneuver all day when powered by our 12V 50ah LiFePO4 batteries. The GoldenMate 12V 50Ah LiFePO4 Lithium Deep Cycle Battery is one of the most advanced lithium deep cycle batteries available. It has an impressive 10-year battery warranty to ensure your satisfaction and peace of mind. We’re in it for the long haul.

Features World-Class Safety Measures

The 12V 50Ah LiFePO4 Lithium Battery is ideal for trolling motor systems, electric scooter systems, and other deep cycle systems as well as backup power and off-grid applications. All our LiFePO4 Lithium batteries feature an integrated microprocessor-controlled battery management system (BMS). Have you heard of a smart battery? This is it! Our advanced system monitors critical operating parameters such as voltage, current, & internal temperatures. (Functions that are vital for safe charging and discharging.) So sit back and relax…your battery can take it from here.

Outlast Lead Acid Batteries With Longer Life & More Efficiency

On average, our 12V 50Ah LiFePO4 battery lasts a whopping 4,000 to 15,000 cycles. Unlike lead-acid batteries that typically last for 200-500 cycles and have a lifespan of around 3 years, GoldenMate LiFePO4 lithium battery can endure more than 4000 deep cycles and has a lifespan of 10 years. Most lead acid batteries have a usable capacity of 50-60%, meaning you have to charge them much more frequently. LiFePO4 Lithium batteries capacity? 99%. Talk about efficiency!
In addition, LiFePO4 lithium batteries can perform well in a wider range of temperatures. They can discharge between –20°C to 60°C (–4°F to 140°F) and charge between temperatures 0°C to 45°C (32°F to 113°F). And don’t worry, if your battery is too cold to charge, the system will automatically recognize this.

Incomparable Weight To Power Ratio of LiFePO4 Lithium Batteries

Our LiFePO4 12V 50Ah battery measures: 8.97″ (L) x 5.43″ (W) x 8.23″ (H). And it weighs a very manageable 14.11 lbs. Unlike lead-acid batteries that come fixed, our 12V 50Ah battery comes with M6 screws that allow it to be installed in any direction. With an impressive 1-3% monthly discharge rate, your cycle will go much further. On the other hand, lead-acid batteries usually discharge 30% per month.

Versatile for Your Needs

Looking for an incredibly lightweight and compact 12V battery? Our 12V 50Ah battery may very well be your best answer! Want to propel a small boat or fishing kayak (up to 50hp) with a trolling motor? Many of our customers purchase two or three 12V 50Ah trolling motor batteries to get the job done.
Are you a solar system enthusiast? Beyond your trolling motor, it can also be the perfect fit for mini solar system setups, small commercial equipment, and more.

Need to connect more than one battery?

No problem! GoldenMate LiFePO4 lithium batteries deep cycle batteries can be connected in series (up to four) and in parallel, as many as needed.It allows for parallel connections up to 200Ah and series for 24V, 36V, or 48V setups, perfect for home backup, security, lighting, solar, and outdoor uses like gardening, fishing, and camping.

Faster and more convenient to charge LiFePO4 battery

The GoldenMate 12V 50Ah lithium battery delivers 640Wh, almost matching a 12V 100Ah lead-acid battery's effective 720Wh at 60% discharge. It can power an 80W load for 8 hours, similar to the lead-acid equivalent, but charges in 1-2.5 hours compared to the lead-acid's 10-20 hours.

1.Are GoldenMate LiFePO4 Lithium batteries safe?

Yes. LiFePO4 is an inherently safe chemistry and the most stable lithium-type battery on the market. GoldenMate lithium cells are UL-certified for the highest safety and sustainability standards. All GoldenMate 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, GoldenMate LiFePO4 Lithium batteries have been tested to be free from the risk of fire, and electric shock in harsh environments.

3.Can I charge GoldenMate LiFePO4 lithium batteries in cold weather (under freezing temperatures)?

The GoldenMate 12V 100Ah LiFePO4 batteries can be safely charged between 32°F to 113°F (0°C to 45°C). But when charging under the freezing point, the battery cells may be damaged.

5.How long to charge GoldenMate LiFePO4 lithium batteries?

You can charge our LiTime 12V 100Ah lithium battery with a 12V 10Ah or 12V 20Ah charger, and a full charge will take 10 hours and 5 hours respectively.

7.What to do when receive the battery?

Upon receiving your battery, please note that it may arrive with a low State of Charge (SOC) as a result of the transportation and storage process. To ensure peak performance, we advise promptly charging the battery to prevent over-discharge.

If you intend to store the battery for an extended period without use, we recommend charging it to a SOC 50% and conducting maintenance every three months. These measures will help preserve its functionality and performance in the long run.

2.GoldenMate LiFePO4 Lithium batteries as starting batteries?

No. GoldenMate LiFePO4 lithium batteries are not intended to be used as starting batteries but energy storage, please do not use them to start any devices.

4.How do I store GoldenMate LiFePO4 lithium batteries?

It is recommended to store GoldenMate LiFePO4 batteries at 50% state of charge (SOC). If the batteries are stored for long periods, cycle the batteries at least every 6 months. Recommended storage environment: 10℃~35℃ (50℉~95℉), 45%RH~75%RH

6.Can I charge GoldenMate LiFePO4 Lithium batteries with solar panels?

Yes, you can charge GoldenMate LiFePO4 lithium batteries with solar panels. There are 3 ways to charge.

1. Using Solar Panels

The battery can be fully charged in one day (with effective sunshine 4.5 hrs/day) by 300W solar panels. It may take more than one day to fully charge the battery by ≥300W solar panels since the duration and intensity of light would be a great factor for their charging efficiency.

Besides solar panels, there are 2 more ways to charge.

2. Generator/Alternator

If the alternator or generator supports DC output, a DC-to-DC charger is needed to connect the battery to the generator; if your alternator or generator supports AC output, please add a suitable battery charger to connect the battery and the generator according to our recommendations. The Recommended Charging Voltage: 14.2V - 14.6V. The Recommended Charging Current: ① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

3. LiFePO4 Smart Chargers

To charge 12V battery, it is recommended to use 14.6V battery charger.

The Recommended Charging Voltage: 14.2V - 14.6V.

The Recommended Charging Current: ① 20A (0.2C): the battery will be fully charged in around 5 hrs to 100% capacity; ② 50A (0.5C): the battery will be fully charged in around 2 hrs to around 97% capacity.

8.Does this battery has low-temperature protection?

Yes, this battery has low-temperature charging-off protection. It's recommend to charge the battery during the temperature range: 0℃ to 50℃ / 32℉ to 122℉.
