12V 400AH BATTERY – SELF-HEATING (DUAL TECHNOLOGY)

Description:

Volthium's 12V400AH LiFePO4 ABS battery in 8D format is manufactured specifically for boats, sailboats, motorized vehicles and industrial applications.

The Volthium 12V400AH batteries, with or without integrated heating system, is ABYC compliant, including clause E-13, regarding communication.

Indeed, the battery integrates the communication allowing the customer to define an audible and visual alert before the batteries fall into protection. Using their cell phone and the Volthium Monitor application, the customer will be able to set an alert for a specific %SOC, of their choice, in addition to setting a warning alert for high temperature, and low temperature. This feature is available on multiple Volthium Batteries. In addition, the 12V400AH batteries are CSA UL1973 certified.

The battery is designed for energy storage banks ranging from 5kWh to 20 kWh.

These batteries have the particularity to have an accessible and reserved chamber for the BMS.

This makes them repairable in case of need, and allows to extend the life of the cells by limiting the transmission of heat to them. In addition, a private BMS room increases the usable temperature range of these batteries.

This lithium battery has an integrated cooling system that allows the heat to escape from the battery via its conductive aluminum plate. Once again, the heat sink further increases the usable temperature range,
while promoting better performance of the integrated BMS. In addition, an additional cooling system can be attached.
Another Volthium exclusivity.

This new generation of batteries is also equipped with a stainless steel 304 UL button, which allows to deactivate the discharge, while leaving the recharge authorized. Extremely, practical when the customer wants to leave the batteries connected to the solar system during storage, while eliminating the fear that they will be flattened by parasitic discharges.

This brand new battery, whose casing is exclusive to Volthium has 2x RJ45 ports, whose pins are gold plated, allowing communication on the RS485 protocol. This connector is also used to transmit the internal information of the batteries to the Victron Venus OS environment (on their VE.CAN protocol).

To be able to make communication working between Volthium batteries and Victron environment, simply get the Volthium HUB accessory VE.CAN ($), another exclusive development of Volthium.

In addition, the RJ45 connector allows you to add the Volthium bluetooth transmitter, which can handle up to 4 batteries when paired with the HUB.

Not only is this LiFePO4 battery resistant to vibrations, but it has a discharge range superior to the competition. In fact, this battery can be discharged down to -30 degrees, instead of -20 degrees for the competition. And if you choose the self-heating option, it can be recharged down to -40 degrees. This innovation is possible because the cells in Volthium batteries come from the automotive industry.

Exclusive Double Self-Heating Technology

The battery is equipped with two internal heating systems. The traditional intelligent system is activated when you apply a recharge to the battery when it is below zero. The second system, called manual, is activated when you apply a voltage to the positive H+ connector (M6) of the battery. This heating system, called manual, is not automated. If you connect the positive terminal of the battery (M8) to the H+ connector (M6) of the battery with a small piece of cable, it will be triggered using the energy of the battery.

  • Attention, it is necessary to use a timer to avoid forgetting the heating in function
  • The manual heating system is reserved for professionals and works down to -30 only.

10 years warranty, useful life around 15 years and more.

Average operation beyond 6000 cycles.

Beat Mattress Protector yet!
Size: Queen, Color: White
This is the ULTIMATE bed protector I’ve bought in MANY years! Fits SUPER deep mattress. Has a nice thick fill. Doesn’t have any crinkle sound when you move nor makes you feel “hot” either. Literally waterproof also definitely works at keeping mattress protected especially against a huge amount of water poured on top! Washes and dries well in the dryer without shrinkage or losing any lot or waterproofing. Don’t use any bleach or softener or dryer sheets. Fantastic but and HIGHLY recommend! Doesn’t shift on bed either. Has full elastic type mesh ALL around the side of mattress that goes underneath to hold firmly in place. Order size of actual bed even if you have extended height mattress.

Great fit, good added comfort, long dry time
Size: Twin, Color: White, Size: Twin, Color: White
I got the regular twin size for my toddler’s bed. Before, he had a yellow foam topper (one of the cheap ones) and a mattress protector that barely stretched to the bottom of the mattress. I LOVE that this is such a deep fit so I didn’t need to worry about it coming up a lot. We have a standard size twin mattress. For breathability, it does seem like it might trap heat- it is very warm to lay on the mattress now, but that doesn’t bother us. It is comfortable to lay on the mattress. I don’t think it is as thick as the foam topper we had, but that was expected. For a waterproof topper, it’s a pretty good fluffiness. Washing: Hours fit in our washing machine fine. However, I did have to dry it three times. You can’t dry it with anything else or whatever else is in there gets bundled up inside it. I didn’t take a star off for this because we generally have to run loads a second time in our dryer anyways, and it might be because of the weight that it takes longer to dry. overall, I am happy with the purchase! My toddler’s bed is much more “in place” with the sheets, it’s still comfortable and the cost is worth the money to me.

Get your comfy on
Color: Black, Size: King, Color: Black, Size: King
This Bedsure King Mattress Topper - Viscose Made from Bamboo: This ultra-soft, thick, and fluffy pillow top mattress pad is made from bamboo and is 21 inches deep with a breathable, moisture-wicking design. It’s available in black and measures 78x80 inches. While it’s a great choice, it does take a bit of time to be able to use when you first receive it. First, you need to remove the packaging and then put it in the dryer on low fluff for 20 minutes. After that, you should lay it across your bed for 24 hours to allow it to expand fully. So, plan on not being able to use it for 2 days. However, following these instructions will ensure that you get the best ultra-soft thickness and the perfect fit for your bed, plus you’ll feel comfortable when you’re ready to sleep on it. This Bedsure King Mattress Topper is incredibly comfortable. You’ll have the best nights’ sleep of your life with it. The quality of this topper is exceptional. I washed it, dried it, and it still came out perfect. There were no clumps or bunching. It laid out perfectly on our king bed mattress. This thing feels amazing. I didn’t want to get out of bed. Being a coffee addict, I didn’t mind not having it first thing in the morning because it’s so soft. My husband even approved of this topper. I like how both of lying on it, I don’t feel him moving around. This Bedsure King Mattress Topper is not too soft that you sink in. It’s just right. It’s like a soft hug on your body, but not wrapped around you. After a few days of sleep on it, my back didn’t hurt. I was surprised. I also like how this topper helps protect and keep your mattress from wearing out quickly. It provides long-lasting stability to your mattress. This Bedsure King Mattress Topper is the perfect thickness. I love how my sheets still fit over this and my mattress with no problems. The topper stays put on my mattress also. I like the added elastic band for support keeping it in mattress. We just bought a new mattress and I wanted a topper to add more comfort so this was a perfect addition. Ive bought other Bedsure items for our condo, we rent out and guests always like those toppers. This the first time getting a single topper with no memory foam added separately. I have to say I like the added comfort this Bedsure King Mattress Topper - Viscose Made from Bamboo Ultra Soft Thick Fluffy Pillow Top Mattress Pad with 21 Inch Deep Pocket, Breathable, Moisture Wicking, Black, 78x80 Inch adds to our mattress top. It’s just the right added comfort. You can’t see the wording Bedsure through sheets either. I get do my stretches in bed, yoga and still able to do with no problems. The price is spot on for a nice quality mattress pad. Definitely highly recommend getting this for your mattress. You will be glad you did. It will last a long time.

A better topper from a company I trust
Color: Black, Size: Twin
I have a memory foam daybed that has seen better days. The top layer has started to shift from regular use, and I wanted something that would help hold it together. The Bedsure Twin Mattress Topper does exactly that and made a huge difference right away. This is a high quality, well constructed mattress pad. It fits securely over an extra thick mattress and stays in place. The corner bands under deep pockets are strong and keep everything aligned without slipping. The measurements are accurate. There are instructions to dry it, then leave it out to expand. There was no weird smell. What you see is exactly what you get, in a good way. The cushioning is even and comfortable, and the fabric feels thick and smooth. It adds structure while still improving comfort. It has a more premium look and function than expected, similar to what you would find in a Five-Star hotel. It feels expensive. I also appreciate that the color is not white. It looks cleaner over time and feels like a more practical choice. I have used several Bedsure products, and the quality has been consistent. I also like that it is a woman founded and owned brand, and they continue to improve their products.

adds a touch of comfort!
Color: Black, Size: Queen, Color: Black, Size: Queen
I ordered this mattress topper for our guest bedroom. It is soft and adds a little plushness to the existing mattress. I ordered the queen size for our queen size mattress. It fit well, without much overlap from the mattress topper. The topper has elastic corner bands as well as the fitted sheet like band around the edge, so the topper should stay in place. The color is black, as shown and if you use light colored sheets, it will likely show through. To combat this, I used a white mattress protector overtop of the pillow topper. You cannot see it through our protector and white sheets. The topper is more like a padded mattress protector than a true topper. It reminds me of a pillow top, it's not foam just filled to add softness to the mattress. I think it's a great addition, it adds a little height and comfort to the mattress. Overall, I think this is a nice upgrade to our guest room. It fits well, and serves its intended purpose. I would recommend to anyone wanting to improve the comfort of their mattress.
