Dabbsson DBS2100B Expandable Battery

The Dabbsson DBS2100B Expandable Battery is a 2150Wh LiFePO4 add-on battery for the Dabbsson DBS1400 Pro and DBS2100 Pro portable power stations. It is meant for home backup, RV and off-grid users who want more runtime from their power station without buying a second unit. It weighs about 44.1 lbs (20 kg), is rated for 4000 cycles to 80%+ capacity, and recharges on its own from up to 1200W of solar.

2150Wh of Extra Capacity for the DBS1400 Pro and DBS2100 Pro

The Dabbsson DBS2100B plugs into the extra battery port of a compatible power station with the included extra battery cable. A single DBS1400 Pro or DBS2100 Pro accepts up to two DBS2100B batteries, and Dabbsson supports systems of up to 2 power stations with 4 battery packs for longer outages, RV trips and outdoor events.

DBS2100B vs DBS2000B: Which Dabbsson Expansion Battery to Choose

The DBS2100B stores 2150Wh and weighs about 44.1 lbs (20 kg); the DBS2000B stores 2048Wh, or 102Wh less, and weighs about 39.7 lbs (18 kg). Both use the same 17 x 10 x 9.5 in (432 x 254.5 x 248 mm) housing, the same 1200W solar input, the same USB outputs and the same 4000-cycle rating. The DBS2100B works with the DBS1400 Pro and DBS2100 Pro.

Recharge From Solar, Your Car or AC Through the Power Station

The DBS2100B has its own solar/car input, so it can charge while disconnected from the power station. It accepts 12-60V DC at up to 25A and 1200W from solar panels with the included solar charging cable, or 12V/24V from a car outlet at 8A by default. AC charging goes through the connected DBS1400 Pro or DBS2100 Pro, at 600W by default; the AC charge speed switch changes the charging power.

Four USB Ports for Standalone Use

The Dabbsson DBS2100B can power small devices on its own through 2 USB-C ports (100W max each) and 2 USB-A fast charge ports (18W max each), switched on and off with a dedicated USB button. The LCD screen shows input and output power, remaining battery percentage and remaining charge or discharge time.

LiFePO4 Chemistry With 4000 Cycles and Six Protections

The Dabbsson DBS2100B uses LiFePO4 (lithium iron phosphate) cells rated for 4000 cycles before capacity drops to 80%. The battery management system covers overload, short circuit, low voltage, overcurrent, over temperature and low temperature protection. The DBS2100B carries ETL, CE, FCC, PSE, UKCA, WEEE and RoHS certifications.
