DENSITY 120Ah AUTO/MARINE BATTERY, 100A BMS, DUAL MPPT, ANDERSON

DENSITY^X2 AUTO/MARINE BATTERY, 100A BMS, 120aH with ANDERSON SB120 and Dual XT60 MPPT Inputs, is part of the Density Link App ecosystem. It delivers solid state safety, high Wh/kg, low temperature performane and very high discharge capacity. 

The battery is designed for high-current automotive and off-grid applications with robust connectors and integrated charge intelligence:

• Primary load & charge port:
  Heavy-duty SB120 Anderson plug rated to carry the full 100A continuous discharge safely. This single connector simplifies wiring and ensures low-resistance, secure connections for inverters, winches, fridges, pumps, or auxiliary DC buses.

• Additional solar/auxiliary input:
  Integrated dual 60 A MPPT controllers with a 10-60 V input range, allowing direct connection from solar panels or auxiliary alternator/DC sources without external regulators. The MPPT tracks maximum power point dynamically for efficient charging in real-world conditions (shade, variable panel voltages).

• Parallel-friendly:
  Multiple packs can be paralleled through SB120s for extended capacity while each MPPT continues to optimize its own charging source.

• Safe & versatile:
  The Anderson connector’s keyed, genderless design prevents mis-wiring. The dual-path system (SB120 for high-power discharge, MPPT for renewable input) ensures separation of load and generation, extending both pack life and safety.
