Why switch to a lithium battery in your campervan?<\/h2>\n

Swapping a lead-acid battery for a lithium one marks a turning point for your campervan. LiFePO4 chemistry offers more usable energy, lower weight, faster charging, better voltage stability and a much longer service life than lead-acid. You\u2019ll notice the difference every day: greater real-world range, fewer worries and the peace of mind that comes with a reliable system, even under high power demands.<\/p>\n

From lead to lithium<\/h3>\n

With lead-acid, AGM or GEL batteries, it is recommended to use only 50% of the total capacity so as not to shorten their service life. With lithium batteries, this usable percentage rises to 80\u201390%. For example: a 12V, 200Ah AGM battery delivers around 1200Wh of usable energy; a lithium battery with half that capacity, 100Ah, already provides around 1000\u20131100Wh of usable energy. And it\u2019s not just that they have more usable capacity: lithium batteries maintain a much more stable voltage, so sensitive devices such as fridges, inverters or routers operate more efficiently.<\/p>\n

Useful energy and voltage stability<\/h3>\n

The key to comfort in a campervan is the usable power available on a day-to-day basis. Lithium minimises voltage drop during power consumption: the fridge no longer \u201cstruggles\u201d, the inverter delivers its full rated power, and the regulator operates within its optimal range. The result is fewer deep discharge cycles and, therefore, a longer service life. Furthermore, lithium batteries charge faster: they can handle higher charging currents (provided the charger and BMS allow it), which is perfectly suited to modern alternators and DC-DC chargers such as the Victron Orion<\/a>.<\/p>\n

The real advantages of 12V lithium batteries over lead-acid batteries<\/h2>\n

Weight, size and ease of installation<\/h3>\n

Lithium weighs between 50 and 70% less than lead for equivalent capacities. In a campervan, where every kilo counts, less weight means more payload for water, bikes or luggage. Furthermore, as they can be installed vertically, horizontally or on their side, LiFePO4 batteries are better suited to the confined spaces of a campervan.<\/p>\n

Long-lasting and requires almost no maintenance<\/h3>\n

A good LiFePO4 battery offers between 2,000 and 4,000 charge\/discharge cycles at 80% DoD, compared with 300\u2013600 for an AGM battery. Maintenance is virtually non-existent: no leaks and no need to check the electrolyte. You just need to ensure that the charger is compatible and to set the charging voltages correctly when installing the battery. Otherwise, all that\u2019s required is some ventilation and an occasional check-up.<\/p>\n

Range and fast charging whilst on the road<\/h3>\n

If you cover long distances between stops, you\u2019ll already know that the combination of alternator + booster charger, such as the Victron Orion models<\/a>, is the best way to ensure your batteries always perform at their best.
Thanks to lithium, you can make the most of every minute on the road: they can handle high-power charging for longer, quickly recharging the energy used overnight to power the fridge, lights and comfort features.
And when power consumption peaks, the voltage remains stable, giving you longer battery life and the real feeling of having a full battery all day long.
Ultimately, lithium is an investment that pays for itself thanks to its convenience, range and reliability.<\/p>\n

How to choose the best 12V lithium battery kit for your campervan<\/h2>\n

The right capacity for your usage<\/h3>\n

When calculating capacity, think in terms of Wh, not just Ah. A simple way to get it right is to add up your daily consumption and add a 20\u201330% margin. Follow these steps to work out the battery capacity you actually need:<\/p>\n

    \n
  1. Make a list of your spending<\/strong>: fridge (40\u201360W on average \u2192 400\u2013700Wh\/day), LED lighting (10\u201330Wh\/day), water pump (20\u201340Wh\/day), laptops (60\u2013120Wh), router (5\u201310W \u2192 120\u2013240Wh\/day), mobile phone charging (5\u201320Wh\/day), etc. The more comprehensive the list, the better.<\/li>\n
  2. Add up the consumption figures<\/strong>: as a guide, an average campervan usually costs between 1,000 and 1,500 Wh\/day<\/strong>.<\/li>\n
  3. Translate it into Ah<\/strong>: Wh \/ 12V = Ah.\n
