Lithium Batteries

Yes, in most 12 V installations, since our batteries run at a nominal 12.8 V. Before switching, check that your mains charger, solar controller and DC-DC charger offer a LiFePO4 lithium profile, and that your wiring and fuses are correctly sized for the system.

There are three methods, which can be combined: a solar panel with a controller, the vehicle's alternator through a DC-DC charger while you drive, or a lithium-compatible mains charger when you are on hook-up at a campsite. Using at least two of them gives you much steadier autonomy.

It depends on your consumption. As a guide, a compressor fridge, LED lighting and phone charging can run for one to two days without any external input. With a solar panel recharging during the day, that autonomy extends considerably.

The 100 Ah MINI is ideal for weekend trips and vehicles with limited space. The 200 Ah PowMr is designed for long journeys, life on board or systems with an inverter and 230 V appliances. If in doubt, send us your consumption figures and we will help you size it.

The BMS, or battery management system, constantly monitors how the battery is working and protects it against overcharging and short circuits. It is what allows a lithium battery to operate safely and keep its performance throughout its service life.

Far more than a lead-acid battery. Both models use grade A cells built for a long service life, and the 200 Ah PowMr reaches up to 6000 cycles. In practice, that means many years of travel with stable, reliable capacity.

As a general rule, only identical batteries should be combined: same model, same capacity, same age and the same state of charge before connecting them. Use cables of equal length and cross-section and the right protection. Mixing different batteries unbalances charging and shortens their service life. Before expanding your system, check the product page or write to us with your wiring diagram and we will advise you.

They can discharge in the cold, although the available capacity drops temporarily. The key precaution is charging: as a general rule, a LiFePO4 battery should not be charged below 0 °C. That is why it is best installed inside the living area, the warmest and best-insulated part of the vehicle, rather than underneath the chassis or in the engine bay.

Ideally in a dry, protected interior location, such as a box under a seat or inside a cabinet, close to the main loads to keep cables short. Secure it firmly so it cannot move while driving, leave space around it to check the connections and fit a fuse close to the positive terminal. The 100 Ah MINI stands out for its compact format for tight spaces.

Yes. The 200 Ah PowMr is designed precisely for installations with an inverter and 230 V appliances, as it offers a large energy reserve. Choose a pure sine wave inverter with the right power for your equipment, and size the cables and fuse correctly, because the current on the 12 V side is high with heavy loads.

With lead-acid batteries, it is recommended not to discharge more than roughly half of their capacity to avoid damaging them. LiFePO4 lithium lets you use a much larger share of every amp-hour without harming its service life. So with the same nominal capacity you get considerably more real autonomy, and a lithium battery can replace a larger lead-acid one.

Grade A cells are the highest-quality cells in lithium cell production: they meet their rated capacity and behave consistently with one another. That uniformity means the battery balances better, performs steadily and achieves a long service life. Both the 100 Ah MINI and the 200 Ah PowMr use grade A cells.

Leave it at an intermediate charge level rather than completely full or empty, and disconnect all loads, including small parasitic drains, using the isolator switch or by removing the main fuse. Store it somewhere dry and protected from extreme temperatures. Check the level from time to time; a solar panel with a controller can help you maintain it.

It depends on your daily consumption and the time of year you travel. Calculate the Wh you use per day and choose a panel output that replaces them in the available hours of sunshine, with a margin for cloudy days. Use a controller with a LiFePO4 profile; MPPT controllers make better use of the panel's energy. Write to us with your consumption and we will help.
