Summary

Shore pass-through built in, No charger

What it is: a 12 V, 2,000 W pure sine wave inverter with a transfer switch and no charger
The trade-off: shore pass-through and a remote panel, but no stacking and app access only through a separate hub
Fit: the manual requires at least 200 Ah of Battle Born batteries behind it
Not checked: Battle Born publishes no no-load draw
Look elsewhere for: a built-in battery charger or parallel stacking

Strengths

Shore power passes through automatically
Control panel mounts away from the unit
Power save mode cuts idle drain
Hardwire AC terminals
Second output sheds heavy loads on battery

Drawbacks

3.3 out of 10

RedditBrand-level3 out of 10

Overall: Reddit threads on Battle Born since December 2025 are mostly negative and centre on the 100Ah battery's positive terminal
Terminal: r/overlanding and r/sailing posts relayed Will Prowse's videos of the 100Ah positive terminal overheating under load (December 2025); Prowse is sued by Dragonfly and is not independent
Response: an r/batteries post quoted Battle Born calling the terminal's aluminum nut a purpose-built thermal failsafe, and owners there called it a design flaw (December 2025)
Suit: r/SolarDIY and r/RVLiving threads on Dragonfly's trade libel suit against Prowse ran largely critical of the brand (June 2026)

GoogleBrand-level4 out of 10

Overall: RV and boat forum owners have turned wary of the 100Ah battery since December 2025, with some long-time owners reporting no trouble
Removed: on Airstream Forums an owner of two 270Ah batteries bought in 2024 took them out of service after the terminal reports (February 2026)
No trouble: another Airstream Forums owner noted Airstream has offered Battle Born for years with few failure reports on the forum (June 2026)
Warranty: Forest River Forums owners objected to paying shipping and possible labor charges on warranty claims (January 2026)
Capacity: a Trawler Forum owner of twelve 24V 50Ah batteries saw about 20 percent capacity loss, and testing found 3 of 12 at end of life (February 2026)
RVelectricity: Mike Sokol, an independent RV electrical safety instructor, ran about 100 full cycles on a new 100Ah at 50 to 70 A without terminal overheating (May 2026)
Disclosure: Sokol also interviewed Dragonfly's CEO for RVBusiness, and does not say how he obtained the battery

YouTubeBrand-level3 out of 10

Will Prowse: tore down Battle Born 100Ah batteries and filmed the positive terminal overheating, then a new unit he bought melting after about 30 cycles (December 2025 to early 2026)
Ties: Dragonfly sued him for trade libel in June 2026 and alleges he earned over $200,000 in Battle Born affiliate fees until October 2025, so his videos are not independent in either direction
Earlier: his teardown of the same 100Ah design about six years before had praised it

AmazonProduct-line3 out of 10

Sibling: the inverter-only BBI2000 lacks an Amazon US listing of its own; the inverter charger sharing its design (B0G1VH4ZT5) shows 1.0 stars from a single one-star rating (October 2026)

Company

Battle Born Batteries is the brand of Dragonfly Energy Holdings Corp. of Reno, Nevada (Nasdaq: DFLI), a company founded in 2012.
Dragonfly Energy acquired the Dakota Lithium brand's assets in July 2026 and runs that brand separately from Battle Born.

Where it sells

It sells with a cart at battlebornbatteries.com, through dealers and installers on its dealer locator, and on Amazon US, where Amazon.com sells its 100Ah battery.

Description

The Battle Born 2000W Inverter, model BBI2000, is a 12 V pure sine wave inverter rated 2,000 W continuous at 40 °C (16.7 A at 120 V, derated above 104 °F) with a 4,000 W surge for 5 seconds. Battle Born rates peak efficiency at 91% and full-load efficiency above 86%, and publishes no no-load draw.

It runs from LBCO voltage to 18.0 VDC (12.0 V nominal, 192 A DC at full load) and its output can be set to 108, 110 or 120 V at 60 or 50 Hz.

It has no battery charger, but an automatic transfer switch with a 30 A relay (24 A continuous) passes shore or generator power through, switching in 20 ms in appliance mode or 10 ms in UPS mode. AC Out 1 runs on battery or shore power, while AC Out 2 is live only when shore or generator power is present.

A power save mode sleeps the inverter until a load of 25 W or more appears. The detachable control panel can stay on the unit or mount remotely with the included extension cable and cover plate, and a CAN port speaks RV-C or NMEA 2000. Bluetooth and the Battle Born app work only through the separate Battle Born HUB.

The manual gives it 14.6 x 12.0 x 4.0 in including flanges and 16.7 lb (the product page and data sheet say 17.2 lb). It runs from -4 to 140 °F, and the manual requires at least 200 Ah of Battle Born batteries behind it.

Optional add-ons are a GFCI kit ($45) and a MiniFit Jr to RJ45 Y cable for the HUB ($50); the inverter-only model cannot be stacked.
