SIB Power 12V 210Ah sodium battery

Low weight of 55 kg compared to a lead/AGM battery saves 50-70% weight. This makes installation easier and reduces consumption.

The sodium battery can be used in all positions, does not leak and does not contain acid.

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

Long service life (6 months+) is not a problem. 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 of up to 5 batteries is easily possible. You can start with one battery and add more later.

The 210 Ah salt battery can be discharged with up to 210 A.

The battery can be discharged up to 100%. No buffer needs to be considered, as deep discharge is not a 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 residual capacity of 80%.

Maximum and recommended charging voltage: 15.8 V

The salt batteries are insensitive to low temperatures. Charging down to -20°C is easily possible, discharging down to -30°C is also not a problem.

Including 250A fuse. Additional charging port via 120A Anderson plug

High safety due to the fact that 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!

5-year manufacturer's warranty. CE certificate

Integrated Battery Management System (BMS) for monitoring the batteries. No overcharging, overvoltage or overheating possible.

With Bluetooth & display for monitoring. RS485 connection for inverters

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

Environmental friendliness / availability of raw materials: Sodium is abundant on Earth and can be mined much more environmentally friendly.

Durability and Usage: Salt batteries cannot be deeply discharged and are therefore much less prone to errors than lithium batteries. In addition, the sodium batteries can even be charged up to -20°C and discharged up to -30°C!

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