Truth behind Chins batteries

[Crowz]

The Chins battery Will did the review on is NOT what you get if you buy one . A guy on youtube did a tear down and review of the same model Chins battery about a year later and it had pouch cells in it. NOT what you see in Will's video . This guy has alot less followers and Subs , so Will's video is what the vast majoroty of viewers are gona see ...and buy , thinking they're gona get what you see in his videos. How many other chi companies do this ? How many other places do they change things for cheaper parts ...and where it may not be as easy to see ?

Ok before I post what I'm wanting post I want to point out that I am not happy with the companies changing stuff around. I bought my first weize batteries based on Will's video on them and his later video shows the changes. That said....


No where do they claim your getting pouch or prismatic cells. Chins also will tell you what you have based on the code and will swap them out from what I have seen others post if you want prismatic after getting a pouch cell battery. So I don't see them doing anything really wrong.

They make a battery that is supposed to do x ah at x volts and be a lifepo4 battery. What type of cells they use has nothing to do with providing a battery that lives up to that as long as they are lifepo4's and add up to the advertised ah. If they don't then bad on them. If they do they did what they were supposed to do.

I want prismatic. Will I send it back if it doesn't have those when I run the sku number after it arrives? Not sure yet.

But at least I have that option and that seems pretty fair for the most part.

My 12volt chins battery gets here tuesday from what the tracking number is showing. I will post my results with it when it arrives.

The 48 volt battery I bought recently has performed GREAT. Very happy with it so far. Time will tell and that's all I have to go on because I'm not cutting open an expensive battery just because I'm curious whats in it

Yes the Chinese hand pick unit for reviewers and send random stuff out to the rest which is why SOK, EPOCH, SFK, VOLTA, AOLITHIUM should be the lowest any reasonable buyer should buy. Wieze, Redodo, Chins, Enjoybot, LiTime, PowerQueen, Varter, are bottom tier for a reason. If it lacks Bluetooth; its for a reason! They DON'T want you to see what is going on with the cells because they don't want you to ask pesky questions about balance and voltage drops and other issues and hence why a lot of these budget brands no longer offer a smart battery.

Thank you, what you just explained was what my gut has been telling me. Send a nice battery to be reviewed and then crank up the assembly line to give the people what they want, but may or may not get. The lower end is such a crapshoot. Not to say there aren’t deals to be had, but I’ll just pay a little extra for what Alkaline refers to as confident lower end options that seem pretty solid mid range picks to me.

I think if you bought it around the time he reviewed it, you'd get what you saw in his YT video ...i don't know how long after that it was when they did the bait and switch . How many other companies do this ...and in areas or parts where it's not as obvious or easy to see . Be nice if ya could just buy stuff and trust it will last . YT videos on new stuff mean NOTHING ... You've gotta do a video on something you've rode hard and put away wet for a year or two ...and by that time, something new came out . These videos are not much more than entertainment. Maybe some value but i guess ...but not as much as most people think....and they know that most people won't open it up and look . If pouch was so great then they'd advertise their product as such ...and boast about it . Anyone boasting about pouch cells ? Why is that

None of them are boast they have prismatic cells either. They don't mention what kind of cells they have in them at all on the batteries I have run across. Sometimes on the reviews people will ask but that's about all I see about it.

From what I can find there is no advantage to prismatic over pouch cells from a functional stand point. Prismatic cells are better if your doing your own battery build since they are easier to handle and not as fragile as pouch cells are. But if put in a sealed container and done properly there doesn't to be any difference. Since these are sealed batteries I see no advantage to prismatic cells except if you plan on cutting them open one day if the battery fails and replacing a bad cell and making a new battery from it.

Several articles that I read said pouch cells can be cycled more and last longer than the prismatic cells (I have no idea if this is true or not its just what I read). This is one article about it :

This article will give you a detailed comparison of prismatic vs pouch cells, enabling you to choose which one you need for your projects or appliances.

I would prefer prismatic but only because if it fails I'm going to open it up and use the cells to make another battery by replacing the bad cell and use a better bms than the cheap batteries come with.

But if I was just going to use the battery and throw it away if it failed the pouch cells seem like they would be fine for that.

This is a common problem with any LFP that is mass produced and then sits in storage for extended periods.

When I get a new LFP I slow charge it to full using a 10amp charger or 200 watt solar panel.

Then discharge under load to about 50% and that usually rebalances the battery and BMS and you are good to go.

Same for power stations.

{sigh}... guess I should have searched the forum before buying chins brand for my golf cart. I started a new thread, and just stumbled on to this thread. Pretty pissed off right now.

I'm running the chins batteries you ordered for your golf cart I imagine. They run my entire house flawlessly. I'm running the 48v with bluetooth versions. Mine are a mix of the 100amp and 200amp versions.
