Handy Remote Reset Switch
The Battery Management System (BMS) in all Hardkorr lithium batteries includes a protection circuit that activates if the voltage drops below 10.0V, preventing damage by putting the battery into ‘sleep’ mode. Previously, resetting the battery was difficult, but with Hardkorr batteries, you can easily reset the over-discharge protection by connecting the included remote reset switch to the battery and holding the button for 5 seconds. The button can also be flush-mounted into your 12V setup for convenience.

Oversized Terminals
The Hardkorr 210Ah Slimline battery features oversized terminals for easy and reliable direct +/- connections. These oversized terminals improve installation and ensure enhanced reliability for off-grid power needs.

Slimline Design for Space Efficiency
With a narrow 50mm profile, the 210Ah Slimline battery is perfect for space-conscious installations in 4x4 vehicles, trailers, or boats. Its slim form factor allows it to be mounted behind rear seats or up on a canopy wall, leaving you more room for other gear. The battery can be mounted in any orientation, and with eight brackets included, you have flexible mounting options to suit your setup.

High-Quality Construction
The 210Ah Slimline battery is engineered using high-quality aluminium-encased prismatic cells, ensuring durability and vibration resistance. At just 25kg, it’s lightweight enough for rugged travel but powerful enough to meet all your off-grid energy needs. This battery delivers 210Ah of usable power, perfect for running 12V fridges, lights, pumps, and even larger devices.

Powerful Performance
With a continuous discharge rate of 250A, the 210Ah battery can power up to 2500W from an inverter, enabling you to run your favourite 240V appliances, such as coffee machines, toasters, and induction cooktops. This capability makes it a standout choice for off-grid adventures. Plus, the Battery Management System (BMS) allows you to link up to four of these batteries in parallel or series, creating larger battery banks of up to 840Ah or systems operating at 48V.

This is the one!
Color: P-Storage Cover Black, Size: Prestige Rechargeable
THE BEST FROTHER!! I use a frother every morning for my skim milk and have gone through several. The battery powered ones I’ve bought work but end up bent and wobbly. I’ve had other rechargeable frothers that don’t have enough power to froth milk more than one day or two. This one checks all the boxes! Comes in a protective case and holds a charge for over a week w daily use. It is so strong I use the low setting for frothing and it makes a beautiful foam top for my coffee. Also use it to mix protein powder into liquid as well as other powders- no lumps! You could easily whip cream w this thing! Highly recommend!

Nearly instant blending
Color: P-Storage Cover Black, Size: Prestige Rechargeable
Wow! That's my impression of this handy gadget. It has a quality feel to it and super easy to understand. I charged it up full and have used it more than a dozen times with no sign of it needing a recharge. My main use is to blend my protein powder into milk and juice in the morning. Let me tell you - it takes about five seconds. Instead of fighting the blend with a spoon for nearly a minute this frother has it done so quickly it's amazing. The powder and fluids are mixed WAY better than with a spoon and in record time. It also makes the drink much smoother and the taste is thick and creamy. It's hard to describe how easily it functions. Oh and clean up? That's a snap. Just dunk it in clear water and turn it on a few seconds. This is one of the handiest tools I've ever added to my kitchen.

Powerful
Color: P-Storage Cover Black, Size: Prestige Rechargeable
The only reason I gave this a 4 star is that I wish it had a slower speed. Have to be careful not to fling liquid everywhere with a smaller cup. It does have power!!
