I searched but nothing popped up under arc-angel or arcangel. I've only found like 6 or 7 reviews online fort these but they all seem positive, has anyone used one of these as a replacement battery before?

I have the original battery in my Q40 still and its time to replace, so figured I'd give one of these a shot. Just wondering if anyone on here has used one?

Basic drop in group 35 replacement and only 16 pounds, and only a couple hundred more than an agm replacement. Amp hours and cca seems good, and I'm in so cal so don't have to worry about frigid temps ever but I guess LiFePO4 is better than lithium in the cold anyway.

I recall one thread on that battery type, but that brand name wasn't part of the discussion. Search on the formula. You won't find much info, regardless.

 

Thanks, I'll be sure to throw up a review when I get it / run it for a while.

 

Why not Optima redtop?

 

15.9 pounds vs 32 pounds and potentially lasts almost 2x as long

 

16lbs really going to make you go faster? Just remove spare tire and take a big number 2

 

Every little bit helps.

 

Battery showed up today, perfect fit in the Q40. Think my scale is off a bit but the difference of the two should be close, 19.5 pounds lost. Cranks the engine noticeably faster right out of the box.

 

I'm glad you are happy with the lithium battery... BUT that $416 price

 

Well I needed a new battery anyway and something like a red top is around 200, so its it’s more like only a 200$ price

It has a 10 year warranty so theoretically over the life it’s no more expensive, time will tell though....

 

I didn't know lithium-iron batteries for cars existing, so I read everything on their website.
They look like a very good option. - nice find!

 

That looks so nice. I realize I'm 2yrs late to the party here, but as of posting this anyway it appears that company has died out. At least that's the sense you get from poking around their site. All their batteries are "unavailable" or "out of stock" sooooo that's never good
