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

Swapping a lead-acid battery for a lithium battery is a game-changer for a campervan. The chemistry of LiFePO4 lithium batteries offers more usable energy, lower weight, faster charging, better voltage stability and a longer service life than lead-acid batteries. The results are evident every day: greater real-world range, fewer worries and the feeling of having a \u201creliable\u201d system, even under high power consumption.<\/p>\n\n\n\n

From lead to lithium<\/h3>\n\n\n\n

With lead-acid, AGM and 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 percentage of usable capacity rises to 80\u201390%. For example: a 12V, 200Ah AGM battery delivers around 1200Wh of usable energy; a lithium battery of the same capacity, 100Ah, already delivers around 1000\u20131100Wh of usable energy. And it\u2019s not just that they have more usable capacity: lithium batteries maintain a more stable voltage, so sensitive devices such as fridges, inverters or routers operate more efficiently. <\/p>\n\n\n\n

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

The key to comfort in a campervan is the usable power available for day-to-day use. Lithium minimises voltage drop during use: the fridge no longer \u201cstruggles\u201d, the inverter delivers its full rated output and the regulator operates within its optimal range. This results in fewer deep discharge cycles and, consequently, 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\n\n\n

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

Weight, size and load capacity<\/h3>\n\n\n\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 LiFePO4 batteries can be installed vertically, horizontally or on their side, they offer greater flexibility when fitting them into the confined spaces of a campervan. <\/p>\n\n\n\n

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

A good LiFePO4 battery has around 2,000\u20134,000 charge\/discharge cycles at 80% DoD, whilst an AGM battery typically manages only 300\u2013600. Lithium batteries require virtually no maintenance: no leaks, no electrolyte checks. You just need to ensure that the charger is compatible and that the charging voltages are set correctly when installing the battery. Otherwise, it just requires some ventilation and the occasional check to make sure everything is in order. <\/p>\n\n\n\n

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

If you\u2019re used to driving long distances between stops with your caravan, 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-ion battery technology, you can make the most of every minute on the road: these batteries can handle high-power charging for longer, 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.
At the end of the day, lithium batteries are an investment that pays for itself thanks to their convenience, range and reliability.<\/p>\n\n\n\n

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

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

When calculating a battery\u2019s capacity, you should think in terms of Wh, not just Ah. A simple way to work out the capacity you need is to take your power consumption and add a 20\u201330% margin.
Follow these simple steps to find the battery you actually need:<\/p>\n\n\n\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\n\n\n
  2. Add up the consumption<\/strong>: As a guide, an average campervan usually costs between 1,000 and 1,500 Wh\/day<\/strong>.<\/li>\n\n\n\n
  3. Translate to Ah<\/strong>: Wh \/ 12V = Ah.\n
