Sodium battery 48V 100Ah

Low weight of 60 kg, compared to a lead/AGM battery saves 50-70% weight. This makes handling during installation easier and reduces consumption. LiFePO4 or Li-NMC is of course slightly lighter

The sodium battery can be used in all positions, does not leak, and contains no acid.

100% maintenance-free: You do not need to regularly maintain the batteries. Over the winter, it is best to charge the battery to around ~60-70% and check the charge level from time to time.

Long storage times (6 months+) are not a problem. A deep discharge is not possible; even after years of storage in a discharged state, the salt battery can be reactivated.

Charging with up to 100 A possible.

A parallel connection is easily possible. You can start with one or two batteries and later add more.

The battery can be discharged up to 100%. No buffer needs to be considered, as deep discharge poses no danger for salt batteries.

Expected lifespan of 10 to 15 years with 4,000 or more discharge cycles - afterwards, the batteries typically still have a remaining capacity of 80%.

Maximum and recommended charging voltage: 59.25 V

The salt batteries are insensitive to low temperatures. A charge down to -20°C is easily possible, and a discharge down to -30°C is also not a problem.

High safety, as sodium-ion batteries (SIB) are non-flammable. Explosions are also not possible.

IP65 protected against water and dust. Ideal for storage on the boat. Touch safe!

2-year warranty from the manufacturer. CE certificate

Integrated battery management system (BMS) for monitoring the batteries. No overcharging, overvoltage, or overheating possible.

RS485 connection for inverters (also suitable as solar storage. We recommend a separate shunt measurement for monitoring, as there is no communication with the e-motors

Thermal stability: There is no risk of overheating and fires - the salt batteries are much safer than lithium batteries.

Environmental friendliness / Raw material availability: Sodium is abundant on Earth, and it can be extracted in a significantly more environmentally friendly manner.

Longevity and Use: Salt batteries cannot be deeply discharged and are therefore much less prone to failure than lithium batteries. Additionally, sodium batteries can even be charged at -20°C and discharged at -30°C!

Lower energy density: therefore, the cells are somewhat larger and heavier than in lithium batteries. On the boat, this usually plays a subordinate role in displacement boats.
