Frequently Asked Question

Whether you choose new batteries from the LBS-M series or 2nd-life modules, it is possible to add new batteries to a system that already has lithium batteries without the risk of damage to any of them. However, they will need to be the same brand and model. Moreover, since our BMS is programmed according to the system we sell, it will be necessary to return it to us so it can be programmed accordingly.

Thanks to their high energy density, lithium batteries are 2 to 3 times lighter than any AGM battery for equal capacities. Moreover, our batteries from the LBS-M series are among the lightest in the market, making them easier to carry and install as well as reducing the load on moving applications (such as marine or RV and van).

Our batteries are designed for deep cycle applications not for cold cranking. That means that they can be fully discharged without arming the battery or reducing its lifetime. However, they can only deliver up to 3 times their capacity, higher current discharge would cause an arm which is why the BMS would shut it down.

Each line of product has its specification, which includes water resistance: our LBS-M line, for example, is fully sealed which means they can be installed in a humid environment; however, they should not be immersed in water.

Upon request, we can build an energy storage system with a rating of IP65, adapted for marine installation. If that is what you are looking for, please fill out The Form to request a customized battery solution.

Lithium batteries have specific charging requirements in terms of amperage and voltages that cannot be provided by an alternator: plugging one of our batteries directly into an alternator would be harmful to our batteries as well as your alternator.

However, several programmable DC-DC chargers are available that can resolve this issue: ask Our Partners for one that can be controlled by our BMS.

Our batteries’ operating temperatures depending on the product line as well. In general, lithium batteries should not be used if their internal temperature is below -5 °C or above 50°C. Our BMS is there to preserve the batteries: if the temperature it measures is not in the operating range programmed by our team, it will stop any charge or discharge from happening. In the case of our LBS-M line, an additional heating module is available. It is also controlled by the BMS and will be started as soon as the batteries’ temperature drops below 0°C.

Our LBS-M series can deliver their full capacity for about 3500 cycles. This represents about 10 years which is the duration of the warranty (8-year full manufacturer replacement warranty and 2 years prorated). After that, they will still be able to deliver 80% of their capacity.

The best way to store our batteries is to charge them at 50%, disconnect them from everything, and place them in an environment where the temperature is above freezing. That way, they won’t need any maintenance or surveillance and will only lose 2 to 3% of their charge. It is important to avoid storing them in a freezing environment because the case could crack, potentially causing permanent damage.

The recommended amperage is half of the capacity (in Ah) of the bank. Our partners will be happy to provide you with chargers that won’t exceed this limit.

Our LBS-M batteries are assembled and built with the highest quality components available: they can withstand vibrations without enduring any arm or reducing their lifespan. It is however recommended to verify regularly if no connection has loosened up over time, especially if they are located in an area that undergoes a lot of vibrations.

If your battery registers between 0 and 5 volts, it is in low voltage disconnect mode. This happens if the battery is discharged of its capacity and protects itself from further discharge.

At this point, you will need to apply a direct 12 V source. This includes the alternator through the starter battery or by connecting it to your starter battery with jumper cables until the voltage reaches 10 -10.5 V.

Some inverter chargers such as the Victron will also take the batteries out of the low-voltage disconnect.

Most programmable equipments are compatible with our systems. Please contact us with the details of your current system and we will let you know if we can make it work.

Please contact Our Verified Dealers if you wish to purchase a product from the LBS-M line. For any other energy storage system, please Contact Us.

Our batteries are fully sealed and made of very stable components. Which means that they won’t catch fire, leak, gas, or corrode. Please note that our BMS is designed to prevent most of these potential issues as well as earth faults. That makes our energy storage solutions among the safest available.

We strive to include all the best safety features in our battery. We are constantly developing innovations to increase the safety of our batteries.

Whether you connect your batteries in parallel or series, it is strongly recommended to use the same brand and model. If it is not possible, they should at least have the same voltage and amperage.

Parallel connection:

Batteries connected in parallel will have a higher amperage but the same voltage as the stand-alone battery. To connect batteries in parallel, you can connect cables between each positive and each negative (see figure p.1). You can also have all the positives connected via a cable to a busbar and all the negatives connected via a cable to another busbar (see figure p.2). In this setup, to keep the batteries balanced, it is very important to have all the cables of the same length and cross-section. A final option to connect batteries in parallel is to place a flat busbar that goes through all the positives and another that goes through all the negatives (see figure p.3). This disposition allows the best distribution of energy which is why we designed our batteries to make this disposition possible.

Series connection:

Batteries connected in series will have a higher voltage but the same amperage as the stand-alone battery. Series connections are particularly interesting in high-power applications since a higher voltage means fewer cables, and thinner cables therefore fewer losses throughout the system. To connect batteries in series, you need a cable that goes between the positive of one battery to the negative of another and repeats that for as many batteries as you have in your battery bank (see figure s.1)

Series-parallel:

Finally, for a high-power system, we usually combine these types of connections to increase both the voltage and the amperage. See figure sp for more details.

To determine how many batteries you need for your application, it is important to decide what you would like to power and how much power you will need within a day. The consumption of each of your loads can be found on the device. Then you just have to multiply by the number of hours (approximate) you plan on using the product. Once you have your daily consumption and maximal peak power, our experts at Lithium Battery Solution, as well as Our Partners, will be happy to discuss your options for the size of your energy storage system.
