The smaller units have a shorter warranty - it looks like you can spend another $300 and get one with low temp cut-off.
Crazy good deal, good find. Thanks for the review.

We used to have a saying: "just because it has a handle, doesn't make it portable". 226#

$3870 for 10kwh is a good deal. It compares to a $500 1280 wh battery. Additional savings comes from the reduced wiring requirements plus having a battery monitor build in.
I guess they are finally taking on the diy firewall market.
My planned system is
- 8 kw Solar
- 32 kw 48v battery
Just 3 of these batteries would do the trick. I won’t be ready for another 2 years, it’s safe to assume the competition will increase and the price will drop.
Exciting times.!

My grandson just told me that he wants to be exactly like you. Because he said that you are a genius in electricity and alternative energy systems. He's only six years old?

[WatchWx]

Love the videos, it's helped us build wireless weather stations for severe weather. Thanks!

[GeraldPUR]

The 10kw/h 200ah one is the one to have. Best bang for the buck hands down

[andrewmo]

If the biggest complaint Will has is, that it is too heavy, sounds like a great battery to me.

[GeorgeWheeler]

As I watch you struggle with that Anderson connector it reminded me of the one I use on our aircraft. A 175 amp Anderson with a little bit of dielectric grease on it changes the whole dynamic.

[GonzoDonzo]

Im becoming a fan of the rack systems for batteries. Seems like this would work well in one if the screen was on the bottom. 2 people could then lift it and slide it right in. Still anything over 200 pounds is going to be cumbersome. Great video

[johnnyh]

SOOO glad to see you testing these. We purchased one back in July/2020 and think its a BEAST. We went with a 48V 10Kwh unit. EDIT: So we just noticed our battery is not even remotely reaching the state of charge you show in your video. (our ceiling appears to be 53.98V) Should we be concerned? We're also in a much colder climate in Idaho! However, the battery lives in a heated workshop at about 58 degrees.

[gymkhanadog]

It's a really good time to be getting into solar and thinking about power walls. I just had a 9kwh system go on the roof with go-live in about 2 weeks, but it's strictly a grid-tie system with no off-grid support (batteries). My SO remembered Tesla Powerwall and got all excited but I told them no on Tesla due to all the problems and high cost. Trying to steer towards an EV battery for price and safety, but seeing products like this starting to splash down is exciting.

After years of watching your videos from Australia I can now happy report you have pronounced “button” correctly at 10:31. Well done will 😉

[southalaska]

Thanks for the review, I've been thinking of upgrading my system to two of the 7.5Kwh packs. Based on what you've shown us here it helps a lot to feel comfortable in making that change.

[marcof.]

BYD just recently announced that they now can produce their BLADE batteries for less than 100$/kWh on the pack level. These batteries are rated for up to 10.000 cycles. That’s for the automotive industry, batteries for home storage usually are a good bit more expensive, at least for now and of course it’s not the price for the consumer. But I expect the prices to drop by about 50% over the next 12 months. At that price point you are down to 2-3 cents per cycle/ per kWh. That makes these batteries interesting not only for people who have solar, but also if you just have hourly tariffs or want to cut down your peak demand. Once people have the batteries, of course they will want to have solar as well.

[MrRickyw]

At 200+ pounds, the fact that you can move the LiFePO4 proves that you are a strong Will. The brain power is further indication of a strong Will. You are helping many.

[matthewwright]

BMS looks like a seplos.
I tried to post a link but think was filtered. A 200amp seplos cost me $250 shipped to my front door. I bought specifically for communication ports so it would communicate with my inverter

[CaseFreefall]

Great content as always! Please if you feel inclined, make an in depth video for us newbies on how to prepare recycled prismatic cells for a battery pack. I love to rescue, and it seems that the scrapyards really want to pawn off LiFePo4 cells to whomever they can. Roughly $2 Australian per kWh which still makes sense to me, even at a severely reduced capacity. All the best :)

[niktak]

Looks pretty good. The price is a bit cheaper than my HSKY's even after the discount.

[maximusmeridius]

been watching all your videos for years here in the philippines.. no bias but 100% honest review for the viewers to know and to learn.... hope to see more new products on your review that has good quality still even its cheaper than other i hate those expensive brands as all hahaha
