Seems like a lithium ion battery that close to a high heat source is asking for trouble.
True, dat. Scary.
Hmm and curious that 100% of the buyers who blew up in a fiery lithium explosion have not been able to leave a review. Talk about survivorship bias.
I’m sure the engineers have condidered that, and there is a heat shield and air space between the fire pit and the battery, isolating it from intense heat.
My brother owns one of these, has had it for quite awhile, and uses it virtually daily. He swears by it. I’ve only been able to experience it vicariously through his (endless) Instagram feed, but it looks very nice while burning.
This sale is pretty lit! 
I mean, I think that’s what the kids say nowadays.

I’ve followed BioLite since their startup days - their first retail product, a compact camping stove, boasted the ability to charge an internal battery using a built in thermoelectric generator plate.
Ironically, this “FirePit+” abandons what made that original product stand out - this battery does not charge from the heat of the fire - you must charge it from separate source.
Their stuff always seemed overpriced for what it was. This $100 off price makes this FirePit+ more interesting. But my concern, it being made out of steel, would be durability.
Another fire pit company, SoloStove also seems to put quite a price premium on their products, but at least their products are made of stainless steel.
BTW, the YouTube video on the front page showing the FirePit+ being used on a breezy beach seems silly. Seems like any fire pit suspended from the ground with a steady breeze would pretty much render the tiny internal fan redundant.
I own one, have had it for four years. It’s pretty amazing. It doesn’t completely whisk away the smoke, but it does a great job at minimizing it. Being able to get the fire going, turn it up for heat and a quicker fire, or down low for a relaxing fire is hard to beat. There’s also a solar cover, which disintegrates when left in the sun (the fabric any ways), but will charge the battery when left in the sun, or you can charge via standard charger cable and removing the battery is very easy. We haven’t cooked on it, but I have brought it to a campsite (that didnt have a pit), and a beach, which was nice, as it provides nice ambience. You can use the lithium battery to charge devices, like a portable speaker.
In terms of it’s durability, I have left it outside uncovered a few times after use, overnight, and I wouldn’t say it’s rust on the sides, but it is definitely oxidation. All in all I would recommend to those whom might find such a device useful. We use it on our back patio as a fire pit instead of one of those big circular ones and everyone likes the heat it provides.
But this defeats the purpose of watching someone sit with a pile of kindling struggling to light it, then picking a different kind of kindling and huffing and puffing like the big bad wolf before it barely lights and a gust of wind takes it out again.
I kickstarted this back in the day, really loved the functionality although it is a small pit/have to cut down the wood quite a bit to fit in.
My TOP gripe/dealbreaker on this is it is not stainless steel/rust proof and will in fact rust very quickly if not covered/left in dry location. For camping this makes it largely just a PIA because even morning condensation would be enough to start the rust machine on this guy.
That was the kickstarter edition, I’m not sure if they’ve addressed the rust issue any further.
