Introducing The 12V 100AH Slimline Lithium Battery from Atem Power - including a 20A 12V DC to DC Battery Charger


Power meets sleek design with the ATEM POWER 12V 100Ah Slimline Lithium Battery bundled with a 20A 12V DC to DC Battery Charger! With a slender profile of just 5cm, this lithium battery defies convention, fitting effortlessly behind or beneath seats, or snugly at the rear of your 4x4, where traditional LiFePO4 batteries dare not venture. Engineered with A grade prismatic cells, this slimline lithium iron battery excels in energy density and consistency, providing a reliable power source for various applications, from camping fridges to 12V lights and high-powered appliances like electric ovens and space heaters.

Encased in a robust SPCC steel enclosure manufactured to Japanese standard JIS G 3141, this lithium iron phosphate battery offers 20% more strength than typical hot rolled steel, ensuring superior protection for the battery cells. Boasting an impressive lifespan of 2,000 cycles with 80~90% usable capacity, this LiFePO4 battery significantly outlasts lead-acid counterparts, promising exceptional longevity and optimal performance. Despite its slender dimensions, this slimline lithium iron battery delivers twice the power of a comparable AGM battery at only half the weight, providing a lightweight yet powerful solution for your energy needs.

Experience high-power output with a max 200A (≤7S) / continuous 100A discharge current, allowing you to run high-wattage appliances effortlessly. Swift charging is facilitated by low internal resistance, minimising downtime between uses. The high-quality BMS ensures precise voltage and temperature monitoring, smart cell balancing, and a low self-discharge rate for sustained charge. The real-time volt meter displays capacity and voltage, while dual 120A Anderson style plugs enable high-current charging and discharging. For added flexibility, connect two slimline lithium iron phosphate batteries in series or parallel to achieve your desired voltage and amp-hour capacity.

Included in this package is a 20A DC-DC Battery Charger with multi-stage charging capabilities. With input options for DC battery and solar, and an operational temperature range of -10℃ to 45℃, this battery charger is the perfect companion for your slimline lithium battery. It features soft start and charge, ensuring efficient and safe charging for your power needs.

This comprehensive package includes the ATEM POWER 100Ah Slimline Lithium Iron Phosphate Battery, 8 mounting brackets, 2 Anderson style connectors, 8 M8 screws, and a user manual.

Purchases made on weekends and public holidays will be processed on the next business day. We send all items via registered courier with tracking.

In some cases where the address is based in the more remote areas of Australia this may take longer. Please note delivery time frames are approximate and are subject to variables outside of our control.


Shipping Costs:

Shipping is FREE on all orders to customers within Australia for San Hima and Ecoflow products.


Large/bulky items (roof top tents / swags etc) will incur a flat shipping fee of $85.

If your delivery address is in a regional or remote location, we recommend shipping to the nearest depot as the most affordable option.

Rural parts within the Northern Territory, Western Australia and North Queensland have seen shipping prices double, triple and even quadruple within the last few years.

For this reason, there may be times where the shipping price listed during checkout is not accurate and additional fees will be charged. It is the customers responsibility to pay these additional shipping fees or we may be forced to cancel your order.

Again, these additional shipping charges only apply to remote and rural areas. if you have any concerns about the shipping price to your address, please contact us before ordering.


Home Delivery (Bulky Items):

This service is generally for products over 40kg in weight, as it is a requirement for these products to be palletised for delivery.

This service utilises power tailgates with two-man crews or crane trucks when required and this is included in the quoted price.

The receiver will be contacted prior to delivery to arrange a suitable delivery date and time. Deliveries are scheduled for either an AM or PM slot on any given day.

Delivery is to front car port, driveway, doorstep or wherever practical depending upon site access. Drivers are not permitted to move item(s) within the residence or around the property due to OHS reasons.

This service assumes reasonable and safe access to the site is available. Overhanging trees, steep driveways, unsealed driveways, narrow driveways or streets or an unforeseen obstruction may deem the delivery unavailable.
