Using highest quality Grade A+ cells, it delivers up to 4000 cycles at 70% depth of discharge. Precision-engineered brackets ensure structural integrity and vibration resistance, while the IP65 waterproof case provides durability and protection.
With a high-discharge BMS, this premium battery provides stable, efficient power and advanced protections for your off-grid system.
Not all lithium chemistry is made equal and Voltanic batteries use the safest & greatest of them all – Lithium Iron Phosphate (aka LiFePO4). With its unmatched chemical stability and exceptional energy density, LiFePO4 sets the standard.
Our batteries come with an In-Built Battery Management System (BMS) which protects against overcharging, short-circuits, and temperature extremes giving you peace of mind plus a long lasting battery.
The Voltanic LiFePO4 battery delivers twice the energy of a standard leisure battery while being half the weight. Say goodbye to the heavy lifting of lead-acid batteries. With its compact design and 360-degree mounting flexibility, you can install it horizontally or vertically, making it perfect for tight spaces and any setup you need.
Unlike lead-acid batteries that can only be discharged to 50% of their capacity, LiFePO4 technology safely delivers up to 100% Depth of Discharge (DoD), doubling your usable power. Voltanic battery cells can be charged and discharged over 6000 times at 50% DoD and around 4000 cycles at 70%
A 12V 300Ah LiFePO4 leisure battery gives you roughly 3600 usable watt-hours of energy (12V × 300Ah = 3600Wh). To figure out how long it will run for, simply add up the watts of all your devices and divide 3600 by that number.
General Guideline:
Remember: Actual runtime will vary based on temperature, battery age, and the type of devices being powered.
Using the Voltanic 200W Solar Panel as an example, the module itself generates around 10 amps per hour in peak sunlight. Since a 300Ah battery needs 300 amp-hours to charge fully, it would theoretically take 30 hours of perfect sunlight to charge it up. However, you typically only get 4-6 hours of good sun per day (in the spring & summer), so expect about 5-8 days for a full charge with a 200W panel.
General Guide:
Remember: Always use an MPPT solar charge controller between your panels and battery to generate the most power and ensure efficient charging.
A typical 12V camping fridge uses around 2-4 amps per hour (24-48 watts) when the compressor is running. However, fridges don’t run constantly—they typically cycle on and off to maintain temperature, running about 30% of the time in normal conditions. This means they average 0.6-1.2 amps per hour (7-14 watts).
Runtime Guideline:
Remember: These are estimates—actual runtime depends on ambient temperature, how often you open the fridge, how full the fridge is, and the efficiency of your system.
The key factor to consider is your battery’s continuous discharge current rating. This is the amount of current (or amps) the battery can safely discharge continuously during daily use. Your 12V 300Ah LiFePO4 battery has a continuous discharge rating of 250A or 3000 Watts (250A × 12V = 3000W).
Therefore, you should not use devices that continuously draw more than 3000 watts, making a 3000W inverter perfect for your setup.
Note: You can technically use larger 4000-5000 watt inverters on your 12V 300Ah battery, as running an inverter at 50-60% capacity (rather than at full load) can actually extend its lifespan. Just remember to never exceed the continuous discharge current limit, or you risk reducing the lifespan of your battery and possibly damaging it.
Remember: Always choose a pure sine wave inverter for optimal performance.
Yes, most standard 12V lead-acid chargers can safely charge LiFePO4 batteries since they charge at similar voltages (around 14.4V). However, there are a few things to consider:
Good to know:
For best results:
Remember: While lead-acid chargers will work, a dedicated LiFePO4 charger is a better long-term investment for optimal battery performance and lifespan.
LiFePO4 batteries require a specific charging profile to ensure safe, efficient charging and maximum battery life. You have several charging options:
Remember: Always match charging voltage (14.4V-14.6V)
Technically yes, a split charge relay could work to charge a LiFePO4 battery since alternators typically output 14.4V, which is within LiFePO4’s charging voltage range. However, it’s not recommended because:
Better solution:
While a split charge relay might work in a pinch, investing in a proper DC-to-DC charger will protect your battery investment and ensure safe, efficient charging.
