13 best marine battery for rv

• BMS stands for "Battery Management System" - the brain of our deep cycle battery. Our BMS protects your battery from most common causes of battery failure, such as temperature volatility or ground faults. The BMS regulates the amount of power taken out of the battery and acts as a shut-off system to protect the cells (and you) from unsafe operating conditions.
• Lithium Iron Phosphate (LiFePO4): Lithium phosphate cells are incombustible in the event of mishandling during charge or discharge, they are more stable under overcharge or short circuit conditions and they can withstand high temperatures without decomposing. When abuse does occur, the phosphate based cathode material will not burn and is not prone to thermal runaway. Phosphate chemistry also offers a longer cycle life.
• Lightweight And Versatile: 27.5 Pounds, it only 1/2 the weight of 12v 100ah lead acid battery! With no acid in the LiFePO4 Battery, you're able to safely mount in any position. This makes batteries perfect for marine, RV, campers, golf cart, off-road and off-grid applications! These can be used in 12, 24 36 and 48 volt systems. ; to avoid battery damage, only connect with this battery, do Not with battery of other brands or capacity.
• Battery Terminal: M6, 1/3 inch diameter of the screw, fit for inner diameter of tray cable 1/3 inch to 1/2 inch, suitable for most battery connecting cables; Battery Size: 12.83*6.69*9.13 inch. Please match the size to perfect fit if install it in a battery box.
• Excellent Cycle Life: Up to 7000 deep cycle times, which provides longer lifespan of 10 years than lead acid battery. we provide free exchange for any quality problems within warranty, please just contact us and we are glad to offer help. Due to the BMS, if put batteries in series or parallel, The maximum series number of batteries shall not exceed two, and the parallel number shall not exceed four.

User questions & answers

Question:	is charger included
Answer:	The band would probably extend far enough to fit on a hard hat, but the bill or rim of the hat might interfere with the light shining down. You might be able to wear it low on your forehead, below the hard hat, but I've never tried that. It might work, but it might be better to find a headlamp designed specifically to wear with a hard hat.
Question:	can this be used as a cranking battery for a bass boat and also run the live wells and electronics all day long? is there a cca rating
Answer:	It's plastic
Question:	Does the low temperature charging cut-off work? Will Prowse (solar power expert) just demonstrated it did not work. What say you
Answer:	Three AAA batteries
Question:	Whichh charger does expertpower recommend (for 10 ah battery)? if battery's built-in bms offers 'complete protection', how can sla charger damage it
Answer:	The tilt is adjustable by notches. For me it's not a problem. It prevents the angle from being easily changed by accidental bumping or jarring that can occur while wearing.

User questions & answers

Question:	Ok should the controller flash when hooked up to my car battery all the time which is the - then battery both flash is that normal
Answer:	The weak point in this system is the controller. I would unhook it and put it in the round file, order a Zamp controller and install it. You will get better readings on your daily collection of amps, battery voltage, and you can use it with LA, LiPo and AGM batteries by choosing the internal settings. No it shouldn't flash, I set mine on a shelf as an emergency back up and installed a Zamp 10 Amp. More expensive, but more quality and more amps to your battery.

Answer:	Hello! The battery dimensions are 12.75" x 6.875" x 9" ( L x W x H). Similar to a Group 27. Thanks!
Question:	At what percentage of remaining capacity does the BMS disconnect from loads
Answer:	The BMS disconnects loads when a cell in the pack falls below in minimum prescribed voltage. When we determine pack capacity (100Ah), the measurement is made from this low voltage to full charge. So based on the rated capacity, there is 0% remaining when the BMS enters low voltage disconnect.

Installing an OPTIMA BlueTop high-performance AGM battery in your boat or RV means exceptional running time and more recharges than you’d get out of a traditional battery. It’s the perfect marine battery for boats with trolling motors, extensive electronic systems, and works well as an RV battery for RVs with creature comforts that tend to drain batteries quickly. On top of providing outstanding vibration resistance, the BlueTop efficient power delivery and faster recharge time mean you’ll spend less time worrying about your battery. This means more time for fun. Again and again. This flexible boat battery and RV battery is ideal for those who need a sure-starting, strong-cranking, maintenance-free power source.

SpiralCell Technology

At the heart of every OPTIMA battery is a series of individual spiral-wound cells comprised of two pure (99.99%) lead plates coated in a precise coating of lead oxide. One coated plate is positive and the other is negative.

The unique manufacturing process of spiral winding continuous lead plates is far more precision-controlled and expensive than building traditional flat plate AGM batteries. Custom automated cell-winding machines are required to maintain the close tolerances required to maintain quality and performance. Critical tolerances, temperatures, humidity and automated processes are maintained and constantly monitored.

OPTIMA has built over 100 million individual spiral cells since the early 1990’s. No one knows how to build the highest quality and best performing spiral-wound batteries better than OPTIMA.

RedTop

For normal engine starting where an alternator immediately monitors the state of charge and provides energy to the battery whenever it is needed.

This would describe most stock vehicles, including: automotive and RV underhood starting, heavy equipment where starting is the primary function, and diesel vehicles without aftermarket electronics.

YellowTop

Use this when electrical loads are higher than average, or when the discharge cycle is more than typical engine starting, such as vehicles with multiple electronic accessories and vehicles without alternators. This can also include vehicles with a lot of factory electronics such as power sliding doors and a DVD player. Examples also include: racing vehicles without a charging system, dedicated drag racers, diesel powered vehicles with aftermarket electronics, and vehicles with inverters, winches, or other accessories.

BlueTop

The BlueTop starting battery (dark gray case) is to be used when a dedicated starting battery is required and it should never be used for cycling duty. Use a BlueTop starting battery for marine applications and RVs when the battery's only function is engine starting.

The dual purpose BlueTop (light gray case) can be used for both starting and deep cycling -- it is a true deep cycle battery with extremely high cranking power. Uses include: trolling motors, marine applications with heavy electrical accessories, and RVs.

User questions & answers

Question:	Which style case do i need for this battery? https://www.amazon.com/gp/aw/d/b008d5yg3g/ref=ox_sc_act_image_2?smid=a3unyf78mgmxy1&psc
Answer:	I have a similar 35AH battery and use this Group 27 box. Good fit.
Question:	Does this come with a strap
Answer:	The cover snaps on, no strap included. You get to customize that for your situation. It’s a great box.
Question:	is it waterproof
Answer:	I wouldn't say it is 100% waterproof. It doesn't have an inside gasket to seal it up. With that said, the top does latch in and you can pull the straps pretty tight. I think as long as you don't submerge it you should be fine.
Question:	Need to know the width at the bottom. Only have 8" in bracket area
Answer:	If you're looking at the Amazon page, it shows several diagrams of the box with dimensions. It clearly shows that it will fit your location. I also have 8" rails and my smaller group 24 battery (that I've upgraded) fits. Ignore the people who said it's 9" wide. That may suggest it won't fit. If you look at the product drawings, it clearly WILL fit. The overall case width is shown as 10", but that's the max width of the top. The bottom is shown as 7.4" and gradually slopes outward as you move up the case. It is designed to fit between 8" rails, which appears to be an RV/trailer standard.

User questions & answers

Question:	How does one buy more than 3 batteries? I need 4 and the pull down menu stops at 3. Do you advise placing two orders of two
Answer:	Yes.
Question:	What is the gassing voltage for these batteries
Answer:	Gassing voltage varies with temperature. For gel cells it’s about 2.35V per cell. Keep your charging voltage below that and no problems. For a standard 12V with 6 cells charging below 14V is safe.
Question:	I have a 2000 12v inverter. what size solar charger do iI need?(how many panels and how many batteries to get the best output on this inverter
Answer:	What is your RV amps? Mine is 30 amps, so solar charge controller MPPT had to be 30 amps as well. Solar panel watts? You can put 4 solar panels at 100 watts each max on this MPPT charge controller. This will easily charge up two 100AJ 12V batteries. With 2000 Watts inverter, maybe add another 100 AH 12V Deep cycle AGM battery to have enough power. I plan to get a 1500 Watt Pure Sine Inverter for my 2 AGM batteries 100 AH 12V each plus 3 solar panels at 100 watts each. Don't overthink this. Too many variables on amp draw and sun strength, angle, time of year, etc. Just ball park it.
Question:	Can power a small tv for camping
Answer:	Yes you need a inverter.
