What are Off Grid Solar Batteries?
Off-grid solar batteries function as energy storage systems.
Since solar power is generated in small quantities, using it immediately can be inefficient. Storing unused energy in a battery allows solar panels to collect energy throughout the day, ensuring that when light fades, you still have power available for your devices.

Lithium Batteries Provide for Solar?
What sets lithium batteries apart from alternatives like lead-acid batteries when complementing your solar energy system?
+ Highest efficiency
With a high-quality lithium battery that achieves at least 95% efficiency, every charge enables you to accomplish more.(others perform at 70%)
+ Longest lifespan
Lithium batteries can be recharged for 3,000 to 5,000 cycles or more, equating to approximately 10 to 15 years of consistent use before needing a replacement.
+ No maintenance
Lithium batteries don’t require regular watering or venting, unlike many lead-acid batteries.
+ Fast charging speed
One common thing of all solar power systems is that they charge much more slowly than traditional grid-operated options. Collecting energy from the sun and converting it into usable electricity inherently takes time.
Lithium batteries charge quickly, and while their efficiency still depends on the solar panels used, they are a superior choice for your solar power system compared to alternatives that may not fully utilize the collected energy.

How to Size Your Off-Grid Solar Batteries?
+ Step 1: Daily Energy Consumption
Calculate the total energy consumption in kilowatt-hours (kWh) for all the appliances and devices you intend to power with your solar system.
+ Step2: Power without Solar Input
Determine how many days your off-grid solar batteries should provide power without solar input. For example, let’s assume 1 - 2 days.
+ Step 3: Battery Capacity Insight
Required battery capacity = Daily energy consumption (10 kWh) x Days without solar input (2 days) = 20 kWh.
Battery capacity = Required battery capacity (20 kWh) / Battery system voltage (24V) = 833.7 Ah.
+ Step 4: Efficiency and Losses
Consider the efficiency of your solar charge controller, inverter, and other system components.
For this example, we'll assume an overall system efficiency of 80%. Additionally, factor in losses from temperature variations, wiring resistance, and battery self-discharge, estimating a total loss of 10%.
The adjusted battery capacity can be calculated as follows:
Adjusted battery capacity = Battery capacity (833.7 Ah) / (System efficiency (80%) × Losses (90%)) = 600 Ah.

Care & Maintenance
Keep the Batteries Clean
Periodically inspect your battery terminal connections to ensure they are clean, secure, and protected from the elements, as corrosion can impair battery performance and pose safety risks.
Store the Batteries Properly
+ A garage or a climate-controlled storage unit could be ideal options to store your RV batteries.
+ Disconnect the Batteries to prevent any potential damage when not in use for an extended period.

How to estimate your boat's power needs?
How to estimate your boat's power needs?
This is useful when you know the power rating of the device.
Wattage divided by voltage gives the amp-hour rating of marine electronics.
For example, assuming you have a 20W light, a 10W navigation system, a 40W autopilot system, a 10W radar, a 40W navigation light, and a 30W water generator, the total wattage is:
W=20+10+40+10+40+30=150W
If you plan on using it for six hours on a single charge,
Wh= 150W x 6h = 900Wh
Now divide this by the voltage to get the Ah rating. For 12V marine systems, Ah = 900 ÷ 12 = 75 Ah

Can the Enjoybot lithium battery be used as a cranking battery?
Can the Enjoybot lithium battery be used as a cranking battery?
No, Enjoybot only offer deep cycle battery, our battery is not designed for starting engines, it can not be used as a cranking battery due to BMS setting. When the boat's engine has started, the boat's engine needs continuous and reliable power for trolling motors, which is where Enjoybot deep-cycle marine batteries come in.
