Lithium Deep Cycle Marine Battery

Jul 03, 2020   Pageview:179

Among several choices available for lithium-ion batteries there is perhaps only one option approved for marine use and that is the lithium iron phosphate battery, which is the type of battery that we are going to be discussing today.

The lithium iron phosphate battery is a type of lithium cell whose positive electrode has iron. Normally cobalt is used but since it is quite expensive and less stable than iron, this type of battery uses iron. Let’s talk about some of its features:

1.This battery has a nominal voltage of 3.2 volts.?

2.Minimum discharge voltage of 2.5 volts and charge voltage of 3.65 volts.?

3.It also has an operating voltage range between 3.0 and 3.6 volts.?

4.The number of charges and discharge cycles varies between 2000 to 8000.

5.Having the most stable chemistry this battery has the rarest history of catching fire.

6.Lithium has some major advantages over lead-acid battery versions. The first and most important advantage is the cycle life of the lithium-ion batteries. With lithium, one can get from 3000 to 5000 cycles, which is quite a lot more than flooded gel-cells or the AGMs in lead-acid versions.

At 50% discharge, the lifeline AGM gives about a 1000-cycles whereas firefly carbon-foam will give you 3600 to 4200 cycles and LiFePO4 will give around 5000 cycles. When the discharge rate goes deeper to 80% then lifeline AGM cycles drop to 550 and firefly carbon-foam cycles drop to 1300 whereas LiFePO4 maintains the 5000 cycles. Going a little bit deeper into the discharges like to 100% the lifeline AGM goes to around 400 cycles and firefly carbon-foam cycles drop to 800 and still, the LiFePO4 maintains its 5000 cycles. This clearly shows that you can get more usable energy for a longer period from lithium.

The second most important advantage that you can get from lithium batteries is the C-rating. The older lead-acid batteries are away behind the new lithium versions, but the new carbon foam AGMs can be compared. Both the firefly and lithium batteries have a C-rating of 1, meaning that you can charge or discharge them up to their amp-hour capacity however fast charging may harm your battery, so it’s not recommended. We may see that the mobile phone companies brag about fast charging, the thing that we don’t know is that this fast-charging typically kills our battery life.

1.These batteries are sealed batteries and don’t require any regular maintenance.?

2.They do not release any type of gas during charging and when they are submerged.

3.They are not position sensitive.

4.Their voltage under heavy load is constant.?

5.They do not self-discharge.

6.They do not need to be float charged.

7.These batteries are the safest version of batteries available today.

8.They are also lightweight when compared to their competitive versions.

Lithium Iron Phosphate battery is a cheaper choice in the long run compared to most of the lead-acid batteries and more capable too.

What Is The Best Lithium Deep Cycle Marine Battery?

1) BATTLE-BORN LIFEPO4 DEEP-CYCLE BATTERY:

The most popular Lithium Iron Phosphate battery is the American Battle-born LiFePO4 deep-cycle battery. Battle-born is an American product made with lithium iron phosphate, delivering a lifetime capacity of 300,000-amp-hours and between 3000 to 5000 charge and discharge cycles. This battery can charge 99% in less than 3 hours and can also be charged with lead-acid battery chargers. This lithium-ion technology makes this battle-born battery get to the top in our list of LiFePO4 batteries.??

2) UNIVERSAL UB121000:

This durable, versatile, and outstanding version from Universal will make your life easy by quickly starting your electronic systems on your boat providing fast and stable performance. This battery does not require any maintenance and goes perfectly well in any boat.

3) MIGHTY MAX MI 35 12 LIGHT:

If you are looking for the best marine battery that is designed for fast boats or applications, then Mighty Max is the right option for you. This battery is considered as one of the favourite back-up batteries.

4) VMAXTANKS SLR 125 AGM.:

This battery is the receiver of top views for ten consecutive years. It is a top-notch performer for anyone who expects non-stop reliability for years. Its superior quality construction will help you in starting any 12V electronic system without any issue.

5) OPTIMA BLUE TOP D34M STARLING:

The blue-top series from optima is the best choice for any boat due to its excellence in recharging methods and times but also for its reliability and performance orientation. It is the best choice for RVs, trolling motors, and electronic systems.?

How Long Does Deep Cycle lithium-ion battery Last?

Lithium-ion batteries last for 2 to 3 years. Having a memoryless chemistry partial discharge does not harm them. Dropping the voltage of a lithium-ion cell up to a certain limit kills the battery pack. They also go through the process of aging and last for about two to three years working or on a shelf.

Talking about deep cycle lithium batteries, they have a lifespan of about 3000 to 5000 cycles and talking in years they may last for 7 to 10 years depending on how frequently you use them.

Is Lithium Deep Cycle Marine Battery Safe?

Lithium deep cycle batteries are the best option for batteries as they weigh about half of the lead-acid batteries and can be an attractive option for boat owners who are concerned about their boat’s weight. These batteries have the safest chemistry making them the most stable batteries available. There are nearly no cases of LiFePO4 battery catching fire till today which is also a type of lithium-ion battery.?

After having a little glance at the LiFePO4 batteries we have discussed some of the major advantages of LiFePO4 batteries compared to its rivals in lead-acid battery types. Some of the top deep cycle batteries have also been discussed. The knowledge regarding the lifespan and safety of these batteries will surely help you in deciding the right choice of battery for yourself.
