A youtuber is getting sued for reviewing this, so let's review it. I love it.

[gfimadcat]

Just the fact that DCS decided to sue someone for a review means I will never in my life ever use a DCS product.

[rossmanngroup]

This gets better and better. Nice review sir!

[roncordell]

OMG that commentary at the end was so spot on. We are fat and lazy and it pisses me off as well. Thanks Will

[muhdiversity]

The funniest thing is the Australian government tested these things, there's a report on an Aussie government website, and the government decided they were garbage too.

[leokimvideo]

Louis Rossmann has really opened up a Hornet's nest related to this Battery, and wow once opened up it's just a cheap ass battery with a high price tag, well done exposing this

[josephb]

I started researching lithium based batteries in 2002. I was a marine tech at a busy boatyard in a major recreational boating area sigh man hundreds of boats including power boats and sailboats. The town, actually an island in the Pacific Northwest, which is the gateway to one of the premier cruising areas in the USA. It has many marinas, most for recreational boats from small to medium-large displacement. I was ABYC certified as a marine electrician. Our boat was a 42’ ketch-rigged sailboat which we took to Mexico in 2004. We departed from Mexico in 2006 and sailed across the Pacific to New Zealand, 2004-2006.

Before leaving I replaced the old AGM deep cycle batteries (400 ah) with a spiral wound AGM start battery. We did not have any significant electrical system problems over the 4 years out. Sold the boat in NZ. Bought a new/used 42’ sailboat after returning. I replaced the 4 8-D AGM house batteries with 16 3.2v LiFePO4 cells (400 ah) after extensive research in the tech. These did not have a built-in BMS. At the time, only a very few lithium “batteries’ had an integral BMS. The ones that did were a bunch of crap. This was just as Victron was starting to introduce builtin BMS. I selected and installed a BMS from Slovenia. I had to manually equalize each cell before hooking them up. I had to replace the delimit the 100A engine alternator to prevent it from self-destructing from the high current draw of the battery. I had a 200A Yanmar driven alternator but I had to seriously upgrade the cables to handle the very large DC charge current. Separate alternator controllers were added to manage the charge profiles for both alternators, with high voltage and low voltage soft disconnect solenoid contactors to prevent unintended low or high voltage.

I mention all this to show that large lithium battery system installations are not for amateurs and that the capabilities of lithium battery systems are variable and subject to wide quality and design problems. Very competent vendors, such as Victron and a very few others, still require a competent marine electrician, thorough manuals and training, and appropriate builtin safeguards. No one likes a fire on a boat. Done right they offer huge advantages over the old tech still in wide use. Much snake oil and mirrors are out there though.

Louis Rossmann highlighting Aussie Govt. testing and reporting DCS batteries are crap was pure gold --- streisand effect

[aarondcmedia]

Louis Rossman discusses the testing the Aussie government did, where they found the DCS batteries were crap compared to all their competitors. The same result the reviewer found. This result is published in official Aus Gov documents on an official Aus Gov website.

[crazyham]

I'm stoked that so many channels are getting on board and supporting him🙏

[jelreviews]

I'm Australian and this DCS company literally lives 20kms from me!! What they've done is absolutely embarrass themselves with their arrogance, and completely exposed themselves with their poor product. There are many reputable Aussie businesses that provide great products and customer service.... DCS provides the complete opposite!

[pete]

How dare you be analytical, honest, and fair minded 😂

[Johnny_Kanuk]

You have to put, "Take a screenshot so I don't get sued" on a Tshirt. 😂😂

[TalRohan]

If the review was anything like yours the youtuber has no problem...youre review is concise, fair and honest.

[chippyjohn]

You realise the US has tried to prosecute Australian journalists for being honest.

[erichconnally]

Dude, I have absolutely loved your journey to where you are now. I don't know when I stopped being entertained by you, and started being educated by you, but you are now my only TRUSTED source for all things solar!

[alexsimmons]

If an idiot wants to attempt to sue, they can. They'll just be thrown out of court. In Australia the burden of proof is on the litigant and truth is a totally valid defence. Not only is truth a defence but even if the statement were not true, then it also has to be proven to have been deliberately intended to harm. Honest opinion is NOT defamation in Australia.

My favorite part was the evil villain laugh when Will brought out the 1000 amp load
