Shop 100Ah Lithium Batteries for Weekends and Aux Power

A 100Ah lithium battery is the usual step off lead-acid for a weekend fridge, canopy lights and a bit of charging. This collection is that capacity across more than one voltage, from a light 12V pack to 24V, 36V and 48V systems.

Read more

Use this size when the trip is a couple of nights or the battery is an auxiliary, not the whole off-grid house. Longer stays, or a fridge plus a hard-working inverter, sit more comfortably in 200Ah lithium batteries. Flat cases are in slimline lithium batteries, and the wider touring shelf is lithium batteries for camping.

Our Range of 100Ah Lithium Batteries

We stock 100Ah lithium batteries from brands already running in Aussie vans, boats and 4WDs:

100Ah Lithium Battery: Who It Suits

  • Weekend touring: Fridge, lights and phones, without stepping up to a long-stay bank.
  • Easy handling: The Amptron 12V 200A pack is 11kg, the Custom Lithium slim case is 11kg, and the Renogy Core Mini is 9.9kg.
  • More than 12V: The same capacity is listed for 24V aux systems, 36V marine setups and 48V banks.
  • LiFePO4: These are lithium iron phosphate packs, so you are not babying a lead-acid half-charge habit.
  • A BMS as standard language: The listings here publish a battery management system, not a bare cell brick.

What to Look for in a 100Ah Lithium Battery

  • Voltage before capacity: A 12.8V pack runs a normal van. The Custom Lithium 24V compact is listed for loads up to 3000W and measures 430 x 295 x 114mm. Marine buyers have Amptron, Enerdrive and K2 36V packs. Amptron's 48V BluEdge is 40.5kg.
  • Case, not just amp-hours: The Enerdrive B-Tec slimline is 551 x 109 x 239mm and 13.5kg. Custom Lithium's Ultra Slim is 55mm thick. A block such as the Renogy Core Mini is 229 x 138 x 213mm. Pick the shape that matches the bay.
  • Phone monitoring: Bluetooth is listed on the Amptron packs, Enerdrive's 24V, 36V and slimline B-Tec batteries, both Tistar batteries and the K2 12V. Treat that as a line on the listing, and match it while you compare.

Frequently Asked Questions About 100Ah Lithium Batteries

Is this capacity enough, or am I shopping a size too small?

For a fridge and lights over a short trip, this is the size most people land on first. It gets tight once you add a microwave, an induction cooktop or several days without a charge. That is the cue to look at 200Ah lithium batteries, not to hope a weekend pack will behave like a touring bank.

Why are 12V, 24V, 36V and 48V batteries in the same collection?

They share a capacity class, not a system. A 12.8V pack is the van and ute default. The 24V compact is for a 24V aux setup, and Custom Lithium lists it for loads up to 3000W. The 36V Amptron, Enerdrive and K2 packs are aimed at marine use. Amptron's 48V BluEdge weighs 40.5kg at 520 x 267 x 229mm, and Custom Lithium's 48V pack is about 50kg at 458 x 310 x 262mm. None of those higher-voltage packs will run a 12V fridge on their own.

What are the Isuzu MU-X and Ford Everest listings doing here?

They are vehicle-specific auxiliary kits, not a loose battery for any tray. The MU-X kit is listed at 15kg and the Everest kit at 10kg, both Australian-made, with an Anderson SB120 on the battery. Notes on both kits recommend a qualified auto electrician, and they allow that some vehicles need minor trimming or drilling. The wiring kit is a separate item. If your wagon is not one of those two, stay with the loose packs on this page.

Which packs in this range list Bluetooth?

Amptron's batteries in this collection list Bluetooth monitoring, including CAN bus or RS485 on the BluEdge gear. Enerdrive's 24V, 36V and slimline B-Tec batteries list a phone app, both Tistar batteries list Bluetooth 4.0, and the K2 12V lists a Bluetooth BMS. The Renogy Core Mini listing leads with the case, the BMS and a 5,000+ cycle claim. Use the monitoring line on the product you are comparing, especially if you want state of charge on your phone.

Will every case in this capacity drop into a standard battery tray?

No. The Renogy Core Mini is a small block at 229 x 138 x 213mm. The Amptron 12V 200A pack is 260 x 168 x 209mm and 11kg, which is a different footprint again. The Enerdrive slimline is long and narrow at 551 x 109 x 239mm, and Custom Lithium's Ultra Slim is 55mm thick. If the limiting measurement is depth, go to slimline lithium batteries and measure the overall size, rails included.

Can I add a second matching pack later?

Yes, in parallel, if the second pack matches voltage and chemistry and you connect them at a similar state of charge. Two matching 12V packs stay at 12V and add amp-hours. Do not parallel a 12V pack with a 24V or 36V pack from this page. Same brand and a close age is the sensible pairing, and the cable and fuse have to suit the higher current.
