Batteries AGM, it is often written VRLA (Valve Regulated Lead Acid). Which means the battery is waterproof. Gas will escape through safety valves only in the event of overload or component failure.

The battery gel is a lead battery with gel electrolyte. Invented in the 1950s in Germany, this type of battery created by Sonnenschein is one of those with an optimal lifespan compared to so many other batteries. More exactly, it is 8 times more resistant than a traditional battery. It is also the most used for storing solar energy.

The lead-carbon battery is a capacitive lead-acid battery, which is a technology developed from the traditional lead-acid battery. It adds activated carbon to the negative electrode of the lead-acid battery, which can greatly increase the life of the lead-acid battery.

OPzS batteries are tubular batteries, they are 2V cells and large capacity, it is necessary to put them in series for a supply of 12, 24, 48V.

OPzS are open batteries, they are easy to use batteries with the best lifespan considering the price.

OPzV batteries

OPzV batteries are tubular batteries, they are 2V cells and large capacity, it is necessary to put them in series for a supply of 12, 24, 48V.

OPzVs are waterproof, their use remains essentially the same, they are easy to use batteries with the best life taking into account the price.

Lithium-iron-phosphate (LiFePO4) has been widely adopted by industry. It is very stable, without risk of fire or explosion, even with a basic BMS.

This battery is also characterized by the large number of admissible charge-discharge cycles, around 3,000 discharges against a few hundred for most batteries sold (lithium or lead).

It also has a particular characteristic, a kind of reverse memory effect: the less the discharge, the greater the number of cycles, which makes it particularly insensitive to microcycling.
