Lithium Battery Deals Australia

You're getting 5.12kWh of rack-mounted LiFePO4 storage plus a free EcoFlow WattLINK adapter for $1,250.99 — that's 10% off the $1,389.99 price when you use code WTOZ10.

• Free adapter is capped at the first 50 rack kit orders, so don't sit on it
• Works with DELTA 2, DELTA 2 Max, DELTA 3, DELTA 3 Plus and WAVE 3 (check your port first)
• Wall-mount and BLUETTI P90D versions are also discounted, from $1,259.99
• Standard delivery is free to most Aussie addresses, with Sydney and Melbourne pickup available

Just confirm the adapter shows in your cart and match both units to within about 1V before you connect anything.

You're getting the EcoFlow Delta 2 1024Wh Portable Power Station for just $719.28 delivered from the EcoFlow Flagship eBay store — just use code TRADE20 at checkout.

• 1024Wh expandable LiFePO4 battery with 1800W AC output (2700W surge) — enough to run a 240V sump pump as a backup
• 1200W AC charging, 500W solar, plus UPS functionality and 100W USB-C
• 5-year warranty with proper local Australian support — no risky AliExpress gamble
• 12kg and genuinely comparable to the popular Anker Solix C1000 deal at $699

Grab it with code TRADE20 while it lasts — this is one of the best-supported power station deals going around right now.

You can grab the WattCycle 5.12kWh 51.2V 100Ah 3U Rack LiFePO4 Battery for just $1,259.99 delivered when you use code WTOZ10 at checkout — that's a $340 saving off the displayed price and only about $246 per kWh, which is seriously sharp for a rack battery with BYD Grade A cells.

• 5.12kWh of storage in a compact 3U rack unit, with a 100A BMS, 3A active balancing, and Bluetooth + touchscreen monitoring
• Expandable up to 20 batteries in parallel (102.4kWh max) — ideal for off-grid solar, home backup, cabins, or farms
• 5-year warranty, extendable to 7 years with registration, plus delivery included for most Aussie addresses
• Use code WTOZ10 before 19 October 2026 — just note it's a battery module only, so you'll need a compatible 48V inverter and cables to get it running

If you're building or expanding an off-grid solar setup, this 15.36kWh LiFePO4 battery is a serious chunk of storage at a solid price.

• Grab it for $2,759.99 (down from $2,999.99) with code HSOZ8 — that's $240 in your pocket
• Free delivery to most Aussie metro and regional areas, plus local pickup available in Sydney and Melbourne if you'd rather collect
• 6,000+ cycles, 200A BMS, and Bluetooth monitoring — expandable up to 15 batteries in parallel if you need more later
• Just double-check your inverter's compatibility before ordering, since it's a 51.2V/16-series LiFePO4 unit (and at 118kg, you'll want a mate to help move it!)

If you've been eyeing an EcoFlow expansion battery, this WattCycle kit gets you 10.24kWh of storage for A$2,816.96 with code WTOZ10 — that's A$363 off buying the parts separately, or about A$275 per kWh including the rack and adapter.

• What you get: 2× 5.12kWh 51.2V rack batteries, a modular rack, and the WattLINK EcoFlow adapter (works with DELTA 2, 2 Max, 3, 3 Plus, 3 Max and 3 Max Plus — but not DELTA Pro or RIVER series)
• The saving: Bundle price drops from A$3,129.96 to A$2,816.96 once you apply WTOZ10 at checkout
• Good to know: Standard delivery is free to most Aussie addresses (WA, NT and remote areas may pay extra freight), and these 41.69kg batteries are really a fixed install, not something you'll lug around
• Also worth a look: The same code takes 10% off WattCycle's wall-mounted and floor-standing home batteries, or use WTOZ6 for 6% off other eligible products storewide

Just double-check your exact EcoFlow model has the compatible XT150-style expansion port before ordering — and note you'll likely need parallel cables and DC protection separately.

Upgrade your 48V golf cart to serious long-range lithium power — this Humsienk 51.2V 150Ah (7.68kWh) LiFePO battery drops to A$1,529.99 when you use code HSOZ10 at checkout (that's A$170 off the A$1,699.99 price).

• 50% more energy than a typical 100Ah/5.12kWh battery — roughly 75-105km per charge on a 2-seater, 60-85km on a 4-seater
• 200A smart BMS, Bluetooth app monitoring, 6,000 cycles at 80% DOD, IP65 metal housing, and a 5-year warranty
• One battery can replace a full 48V lead-acid bank (eight 6V, six 8V, or four 12V batteries)
• Battery-only option — measure your compartment (680 × 320 × 262mm, ~63.2kg) and check compatibility before ordering

Shipping is calculated at checkout based on your address, so factor that in before you grab it.

Need to power something enormous? This 12V 628Ah LiFePO4 beast from WattCycle packs roughly 8kWh into a single unit — equivalent to two 12V 314Ah batteries — for $1,662.50 with code WTOZ5.

At this price, you're getting serious energy storage without the lead-acid bulk — grab it if you've got a big power project that needs feeding.

If you need serious off-grid power, this 460Ah lithium battery packs a massive 5,888Wh — that's enough to run big setups without breaking a sweat.

• 460Ah useable capacity, 300A continuous discharge, and stackable design for expanding later
• 5-year warranty plus Bluetooth monitoring and a remote display for easy checking

Honestly, 48kg is hefty, so you'll want a hand lifting it into place — but for this much capacity at this price, it's a solid deal if you're after a huge 12V setup.

If you're after a big battery for your 4WD or camper setup without blowing the budget, this is about as cheap as a 120Ah lithium gets.

• $249 for a Kings 12V 120Ah LiFePO4 deep cycle, with free click & collect or in-store pickup
• Backed by a 3-year Adventure Kings warranty
• Heads up: the brand doesn't publish a proper spec sheet for this one, so do your homework on whether it suits your needs

At this price it's worth a look, but if detailed specs matter to you, you may want to dig a little deeper before grabbing one.

If you've got an EcoFlow DELTA 2 or 3 sitting around, you can now give it serious off-grid legs with WattCycle's 5.12kWh rack battery + WattLINK adapter kit — down to A$1,319.99 with code WTOZ130 (that's A$130 off the already-reduced Spring Caravan Sale price, and about A$258 per kWh including the cable).

• Includes a 51.2V 100Ah LiFePO4 rack battery (BYD Grade A cells, 6,000 cycles, 100A BMS, Bluetooth + LCD) plus the M8-to-XT150 style EcoFlow adapter cable — no soldering or programming needed

Aldi's Special Buys is dropping a 100Ah lithium battery for just $249 on Saturday 12th September 2026 — that's seriously cheap for this capacity, so it's worth a look if you need power for camping, a 4WD setup, or a solar project.

• $249 for 100Ah is a genuinely sharp price — comparable batteries usually run well north of $300
• One honest heads-up: it's listed as a generic Lithium Ion battery with no brand, model, or confirmed voltage (likely 12V), so do your homework before relying on it for anything critical
• Saturday 12th September only — Aldi Special Buys sell out fast, so get in early if you're keen

If you're after a budget battery for a low-stakes setup, this could be a steal — just don't expect premium peace of mind at this price.
