Scenic roads, beautiful views, and freedom. Van life comes with many exciting perks for those who wish to embrace a life of simplicity and adventure. Solar batteries are one of the most vital necessities for van life, as they power your fridge, water pump, heater, lights, and air-cooling system. 

The best solar battery for van life is the Battle Born LiFePO4. It has a long lifespan, a 10-year warranty, a broad operating temperature range, and a built-in battery management system that monitors and regulates current, voltage, and temperature volatility. 

Battle Born batteries, however, will not be suitable for you if you are looking for the following: 

This article will take a more in-depth look at why Battle Born LiFePO4 batteries are the best overall solar battery for van life. It will also present four alternative batteries that are suitable in other circumstances. But first, let’s quickly go through the factors to consider when purchasing a solar battery

Factors To Consider

When purchasing a solar battery for van life, there are three things to take into consideration:

  • Lifespan 
  • Size 
  • Weight 

Let’s look at how each of the five solar batteries measures up.

Winners: ExpertPower LiFePO4 and Battle Born LiFePO4

The very first thing everyone wants to know about a battery is how long it will last. 

ExpertPower and Battle Born have the longest lifespans. ExpertPower is capable of running for 2,000 more cycles, while Battle Born can initially operate for 500 more cycles at full capacity. A cycle is when a battery is used until it is completely drained and then charged back up to 100%. 

Depending on the electrical appliances and equipment connected to a battery, a cycle may last about a day, give or take a few hours. Therefore, 3,000 cycles may last a minimum of about 8 years. However, the battery’s depth of discharge (DOD) often decreases after that. 

DOD is the percentage of power that can be withdrawn from the battery relative to its total capacity. 

For the Battle Born battery, the DOD decreases from about 100% to 75%-80% after 3,000 cycles, while ExpertPower’s DOD drops to 80% after 2,500 cycles. At the 7,000-cycle mark, the DOD for the ExpertPower battery is 50% of its total capacity.

Winner: Battle Born LiFePO4 

Given that van life involves living in a limited space, the size of items stored inside the van can considerably impact comfort levels. For this reason, batteries that take up less space are preferable. 

Although the size differences between the five batteries may not seem significant when considering a single battery, it adds up when you need to connect several batteries to expand capacity.

Weight Comparison

Winners: ECO-WORTHY LiFePO4 and ExpertPower LiFePO4

The weight of the cargo that a vehicle has to carry has a significant bearing on its fuel efficiency—the heavier the weight, the more fuel that the vehicle consumes. Therefore, batteries that weigh less are more advantageous. 

Looking at the size and weight comparison tables, however, lighter doesn’t necessarily mean smaller. The ECO-WORTHY LiFePO4 and ExpertPower LiFePO4 batteries are longer and wider than the Battle Born LiFePO4, which is the heaviest on the list. 

Therefore, you may have to decide for yourself whether size or weight matters more to you and your van life setup.

With the unbeatable combination of a long lifespan, compact size, and an industry-leading 10-year warranty, the Battle Born LiFePO4 is one of the most popular solar batteries for van life for a reason. 

Battle Born’s renowned warranty is one of its most attractive features. The warranty guarantees that all the batteries and other products that Battle Born or its authorized distributors and dealers sell are free from defects for 10 years. 

If any problems occur within the first 8 years of purchase, Battle Born will credit, replace, or repair your battery. Any defects detected after that until the 10-year mark after purchase, Battle Born will either repair the battery or give you a discount of 30% on a new similar item. 

Unfortunately, Battle Born does not offer refunds on purchases. 

Another popular aspect of the batteries is that they charge exceptionally fast, reaching a full charge in an average of 5 hours. Their in-built Battery Management System provides robust protection against temperature, current, and voltage fluctuations, including a vital low-temperature safety cut-off. 


  • Long-lasting: Battle Born batteries provide a minimum of 3,000 cycles, after which they can last for a further 2,000 cycles at 75%-80% capacity. 
  • Compact size: Given that space is precious for van life dwellers, this battery’s smaller size means they can readily incorporate it in their setup. 
  • 10-year warranty: One of the key selling points of the Battle Born batteries is its industry-leading warranty. 
  • Reliable battery management system: Battle Born’s robust BMS allows you to use it worry-free with the knowledge that it will safely regulate fluctuations of any kind. 
  • Fast charging: This battery takes approximately 5 hours to fully charge, which is relatively quicker than other LiFePO4 batteries. 
  • Free ground shipping: Battle Born ships all orders made within the continental United States for free. 


  • Expensive: It is the most costly battery on this list, and its hefty price tag means that it falls out of many budget-conscious van dwellers’ price ranges. 
  • Weight: As the heaviest battery on this list, its weight may impact its relative portability and possibly affect the van’s fuel consumption. 
  • Larger Ah size batteries are not immediately available. Battle Born only has the 100Ah battery on offer on Amazon, which may be limiting for those who require other sizes. 
  • No refunds: Unlike other solar battery manufacturers, Battle Born does not offer refunds on purchases, which may be highly inconvenient for some customers, especially given their prices.

  • 100% Protection & Delivery
If you make a purchase, you support Hi-van.com by allowing us to earn an affiliate commission (no added cost for you).

Are you traveling to and through rugged terrain that may involve a wide range of temperatures and wet conditions? Then the Ampere Time LiFePO4 is the best battery for you. 

With features such as vibration resistance, IP65 level water resistance, and the capability to perform within a substantial temperature range of between -40°F and 140°F (-40°C and 60°C), these batteries are perfect for use on far-flung adventures. 

For van life dwellers with high-energy demanding electrical equipment, Ampere Time’s 12V batteries also come in 200Ah and 200Ah Plus Size, which are bigger and slightly more expensive. Ampere Time’s Battery Management System (BMS) protects it from overcharging and over-discharging. 

It also regulates against current surges and potential short-circuiting; however, it doesn’t provide low-temperature cut-off. 


  • Water and vibration-resistant: You can go off the beaten path, down dirt roads, and in damp conditions without worrying about the battery’s performance. 
  • Broad discharge temperature range: This battery’s ability to operate in temperatures as low as -40°F (-40°C) makes it a versatile choice for van life. 
  • Easy to install: Ampere Time provides bolts and nuts in its shipment to assist with installation. 
  • Low cost: At about $200 – $300 cheaper than the average industry price, this battery is easy on your pockets. 
  • 5-year warranty: Ampere Time’s warranty involves analyzing and troubleshooting any battery issues within 24 hours, and if they can’t solve the problem, they will send you a new replacement battery. 


  • No low-temperature cut-off: Although you can use this battery in low temperatures, you should not charge it, or any other lithium-ion batteries in general, when temperatures are below 32°F (0°C) because it may permanently damage their cells. One of the functions of the BMS is to guard against this by automatically shutting it off if temperatures fall below 32°F (0°C). 
  • Bulky: Longer and taller than the other batteries on the list, you might have a bit of trouble finding adequate space for this battery. 

Best Solar Battery for Weight and Space Savings: ECO-WORTHY 12V 1000Ah LiFePO4

  • Short warranty: Given that ECO-WORTHY states that its batteries have a 3,000 life cycle, which means it may last for about 8 years, its 1-year warranty seems relatively short in comparison.
