100Ah Deals Australia

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

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.
