Detailed description
Detailed description
The 48V 120Ah service battery from Solid State Marine is a key product in the manufacturer’s 48V range. With 6048 Wh in an 8D format and a weight of approximately 27.2 kg (60 lb), it targets boats needing a genuine 48V bank without opting for the largest references.
Available Currents and 48V Applications
This model supports a continuous discharge current of 250 A with peaks up to 500 A, making it suitable for electric propulsion systems, high-consumption onboard equipment, or highly integrated 48V architectures. The solid electrolyte technology enhances safety by eliminating the flammable liquid electrolyte found in standard lithium batteries.
Monitoring and Network Integration
Built-in Bluetooth allows simple monitoring via smartphone, while NMEA, CAN, RS-485, or Victron versions facilitate integration into a more comprehensive onboard system. The BMS manages essential protections without relying on artificially detailed cutoff values. IP67 housing and M8 terminals.
