Is it possible for 815€ this pack of 16 batteries in 3.2V 320 Ah?

In 24V, it gives 7 kWh, right? there's an extra "0", I was thinking more at that price of something in the 2 kWh range, and BMS to add.

I bought 4 lifepo4 200ah 3.2v batteries on Aliexpress for 280 euros delivered...they work well.

That they work, well yes, but is the power given at the appointment?

For your 200 Ah, do you have about your 200 Ah?

Yes, I tested in discharge at 10a, I have the 200ah
For the power, I don't know, I only ask them 10 to 20a max

In 12V, that gives you about 2400 Wh, how long have you been using them and how often?

Not much, it has 12 cycles, it's for my motorhome.

phil you post here a promo price at -60%... and on ali below 95% positive opinion it's generally not terrible as a seller...

Buy them and let us know!

What do you think, why am I posting this?

The 60% ali, you have some, 30%, always, it's all about knowing what price you're starting from.

On ali, you find 18650 to 9900 mAh, something currently impossible.

Stuff of course ali, yes, I have some that are several years old, and it rolls.
Shit, yes, there's plenty too.

For 320 Ah, one might wonder, if it's not 100 Ah, in fact.

we can't answer you,

the Chinese have quite low production costs, and sometimes stocks that they want to purge.

the Chinese also rip off from time to time.

Buy and you will know.

Roughly speaking, in my experience, 1/3 of Ali products do not conform to the description or fail after a few uses...but on the next 2/3 you can do good business...

For example, in 2018 I bought a Bushnell riflescope at 40€ for my pellet rifle, the same model is sold in Europe for more than 1000€... I saw that afterwards!

I don't use it often, I'm not a shooting professional, I don't know if it's a fake (no instructions or bushnell box...)...but it seems to be of good quality and still works well after years ... for me it suits me!

If it's a fake, they are very strong in counterfeiting...
If it's not a fake, they are very strong...

ps: the product sheet has since disappeared...
