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.

Your high-energy dog will love it!
Why did I wait so long to get one of these?!? I am the stereotypical throws-like-a-girl person, and my dog really needs to have an option that forces her to run far and fast. This is it. I can get that ball half a soccer field away at a minimum if I want. The ball is super bouncy, which adds an element of fun to her attempts to tame it and bring it back. Super worth the money (which wasn't much!). I've never had one of these before, so can't compare to the non-folding version. This one is easy to carry and fits in a drawer for storrage. No way you can fit it in a pocket, especially if you have a phone in one and dog treats in the other.

Great usability
I prefer this version over the non-foldable stick, as this one I can fit into my bag and carry it out easily. Great size and has a locking feature to prevent it from folding up when throwing. Highly recommend, my dogs love fetch and it is hard to chew if they get their hands on it.

Almost Perfect
If you’ve ever seen these things, the foldable ones are just as good as the standard ones. I just wish when you folded it up there was a way to lock it into that position. When you unfold it to play, you lock it into place with the orange locking slide so it doesn’t fold up on you. But when you’re done playing and fold it up, there’s no way to lock it into that position, it can keep unfolding if you carry it around with you, plus the orange locking slide keeps sliding up and down. It’s not a huge deal, but they could’ve made it better.
