Dabbsson DBS2000B Expandable Battery

The Dabbsson DBS2000B Expandable Battery is a 2048Wh LiFePO4 add-on battery for the Dabbsson DBS1000 Pro portable power station. It is built for campers, RV owners and households that want more runtime from their DBS1000 Pro without buying a second power station. It weighs about 39.7 lbs (18 kg), is rated for 4000 cycles to 80%+ capacity, and recharges on its own from up to 1200W of solar.

Dabbsson DBS1000 Pro + DBS2000B: 3072Wh and 2400W

The Dabbsson DBS2000B connects to the extra battery port of the DBS1000 Pro with the included extra battery cable. Paired with a DBS1000 Pro (1024Wh), the system reaches 3072Wh with 2400W of rated AC output at 100-120V. A single DBS1000 Pro accepts up to two DBS2000B batteries, and Dabbsson lists a maximum of 10240Wh when two DBS1000 Pro units are linked with four DBS2000B batteries.

DBS2000B vs DBS2100B: Which Dabbsson Expansion Battery to Choose

The DBS2000B stores 2048Wh and weighs about 39.7 lbs (18 kg); the DBS2100B stores 2150Wh, or 102Wh more, and weighs about 44.1 lbs (20 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 DBS2000B is the lighter option for the DBS1000 Pro.

Recharge From Solar, Your Car or AC Through the DBS1000 Pro

The DBS2000B 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 DBS1000 Pro, at 600W by default; the AC charge speed switch changes the charging power.

Four USB Ports for Standalone Use

The Dabbsson DBS2000B 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 DBS2000B 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 DBS2000B carries ETL, CE, FCC, PSE, UKCA, WEEE and RoHS certifications.
