The ZERO BREEZE Mark 3 Battery is the 1022Wh pack built specifically for the Mark 3 air conditioner, and it is what takes the unit off the grid. It uses 21700 lithium-ion polymer cells, weighs 14 lb (6.4 kg) and measures 20" x 8" x 4" (51 x 21 x 11 cm), with two rubber handles, covered ports and a cable integrated into the housing so there is nothing loose to pack or lose. The pack latches underneath the air conditioner and connects through ZERO BREEZE's own DC connector - no extra cable is needed to join the two, since each battery arrives with its connection cable built in. Note that this pack is made for the Mark 3 only. The older Mark 2 runs on a 24V DC battery while the Mark 3 runs on 48V DC, so the two generations are not interchangeable.

Output is rated at 550W maximum across a 42V to 58.8V range, which is what the Mark 3's 48V compressor expects. The pack also works as a standalone power source: a 12V Anderson port supplies up to 10A (120W), a USB-C port delivers PD up to 100W, and a USB-A port runs QC 3.0 at 18W, enough for laptops, drones, phones and camp lighting on days when the air conditioner stays off. Because the battery talks to the air conditioner, charge level, estimated remaining runtime and charging status all appear on the Mark 3's remote and in its app rather than only on the pack itself. Protection circuitry covers short circuit, overcurrent, low voltage and over-temperature conditions.

Charging accepts 12V to 60V DC with a 10A charging-current ceiling, and there are three published routes in. The official ZERO BREEZE adapter takes the pack from empty to 80% in roughly two hours. Solar works through the battery's built-in 500W MPPT controller with 12V to 60V panels, and in strong sun ZERO BREEZE also quotes about two hours to 80%. A 12V vehicle cigarette socket is the third option. The solar cable and the car cable are separate accessories rather than box contents, so order the one matching your setup. Charging while discharging is supported, which means pass-through operation: the Mark 3 can keep cooling while the pack behind it takes a charge from the wall, a panel array or a vehicle socket.

Up to five packs can be chained together for longer unattended runs, and handoff is automatic - when one pack is spent the next takes over, so nobody has to get up and swap batteries overnight. ZERO BREEZE's published runtimes per battery count are 2-7 hours on a single 1022Wh pack, 4-14 hours on two packs (2044Wh) and 6-21 hours on three packs, with mode-by-mode figures of 5-7 hours in Sleep on one battery and 10-14 hours in Sleep on two. Actual runtime moves with the selected mode, the outside temperature and the humidity. On longevity, ZERO BREEZE rates the pack for more than 1,000 full charge and discharge cycles at normal temperatures, retaining roughly 87% of its original capacity at the 1,000-cycle mark.

ZERO BREEZE covers this product for one year from the date of purchase against defects in materials and workmanship. Registering the warranty card included in the box adds a further six months of coverage.

Because this unit was not purchased on the manufacturer's own site, warranty service is handled by the dealer rather than by ZERO BREEZE directly. Contact Adventure Motion support with your order number and photos or a short video of the fault and we will process the claim for you.

Normal wear and consumable parts are not covered, and neither is damage from drops or impact, liquid entering the housing, disassembly or repair by anyone other than an approved technician, or running the product outside its rated voltage and operating limits.

Will this battery work with a mark 2?
No. zero breeze builds this pack specifically for the mark 3 air conditioner. the mark 2 generation runs on a 24v dc battery while the mark 3 runs on 48v dc, so the two are not interchangeable.
Do i need an extra cable to connect it to the mark 3?
No. each battery comes with its mark 3 connection cable built into the housing, and the pack latches under the air conditioner and connects through zero breeze's own dc connector.
How do i charge it, and is a charger included?
The pack takes 12v to 60v dc with a 10a charging limit and can be charged from the official zero breeze wall adapter, from 12v-60v solar panels through its built-in 500w mppt controller, or from a 12v vehicle cigarette socket. the wall adapter, the solar cable and the car cable are all ordered separately - the carton holds the battery and the manual.
How fast does it charge?
Zero breeze quotes roughly two hours from empty to 80% using the official adapter, and also about two hours to 80% from solar in strong sunlight through the built-in mppt controller.
Can i run several batteries together and will i have to swap them at night?
Up to five packs can be chained. zero breeze states that when one pack is exhausted the next takes over automatically, so no manual swap is needed. their published runtimes are 2-7 hours on one battery, 4-14 hours on two and 6-21 hours on three.
How long will the pack last before it wears out?
Zero breeze rates it for more than 1,000 full charge and discharge cycles at normal temperatures, with approximately 87% of its original capacity remaining after 1,000 cycles.
