The fact the e-bay advertises the product at that price isn\'t any indication that anybody has bought it. It is possible that it might work better in some peculiar application than a couple of lead acid batteries - it\'s almost certainly going to be lighter, for a start.

A dim wanker like you wouldn\'t know about anything like that. The ad may be aimed at a different kind of dim wanker - possibly a greeny, but not all greenies are dim wankers.

I\'ve got a gro-something else, an LED lamp with UV and er.... I must have got it for my parrots. Yes that\'s it, they like pure daylight.

Anyway, I\'ve looked at many places to buy Li Ion and Lead Acid, and it\'s pretty much 7 times more expensive for Lithium for no good reason. I\'m even thinking of using Lead Acid in an electric car to extend the range.. Sure, heavier, but no more than a 3 adults sat in the back. And if it\'s at home for solar, no point in saving weight whatsoever.

Any product that depends on mined minerals might be said to \"rape the earth\". Lithium isn\'t special that respect, and lead acid batteries are just a bad.

Lithium batteries aren\'t any kind of \"nightmare to recycle\". They haven\'t been around for long, so it\'s a fairly new line of work, but that doesn\'t make it a nightmare.

There\'s certainly nothing particularly green about them - they are used in electric cars and the green party approves of them, but only because electric cars can be run off renewable power (not that all than many of them are at the moment).

Commander Kinsey is just doing his dim right-wing troll thing, and should be ignored.

No lead-acid can provide the performance that is *claimed* here.
Recommended depth of discharge for even cyclic l-a is 50% for maximum
quoted lifetime, which is up to 1000 cycles but in the real world
usually rather less. Recharge time is normally much less for lithium.
The maximum charge current for SLA normally means at least six hours\'
charging time, preferably twice that for maximum lifetime.

Of course, lead-acids tend not to burn...

Horses for courses.

And similar for Li Ion. 50% discharge 900-1500 cycles.

> Recharge time is normally much less for lithium.

Irrelevant. Nobody needs to charge that fast for solar for example, yet people are fitting them into their homes.

The maximum charge current for SLA normally means at least six hours\'
charging time, preferably twice that for maximum lifetime.

6 hours? Kinda similar to the length of usable solar.

And why are you quoting SLA? Deep cycle flooded is cheapest and best.

Of course, lead-acids tend not to burn...

Horses for courses.

SEVEN TIMES CHEAPER.

Or.... pay the same and have 7 times the capacity, which of course means you\'re also charging them slower....

You seem to misunderstand units of energy. Wasn\'t your claimed degree in
Physics?

6.5kWh at 12V is over 500 Ah, I would love to see where you can get
decent lead acid batteries of that capacity for £150.

Lead acid batteries shouldn\'t be discharged to less than 50% or
irreparable damage ensues. So in practice you will need 1,000 Ah at 12V

A lead acid battery will have at most a 2,000 charge discharge cycles.
The cheap varieties you\'re comparing with will be 80-200
charge/discharge cycles.

In practice Lithium can manage 3,000 cycles or more, as long as they are
looked after by a decent BMS. Furthermore you can discharge them down to
10% without irreparable damage.

A bit of googling and you could have found this all out by yourself.

In short Lithium is an economic alternative to lead acid. As you have
since discovered there are cheaper lithium batteries around.

 

[Brian Gaff]

I find this hard to believe unless the Lithium one has been priced wrongly.
The power weight and size density is far better in Lithium cells than in
Lead acid ones. It depends if size and weight and max current are an issue
or not.

I was listening to a science program a couple of weeks ago, and they seem to
be wondering that when they look at the spectrum of some asteroids they
seem to be giving a high indication of Lithium content. If that is the
case, is it not odd that as the earth was apparently built from this stuff
that its not abundant here as well? Who nicked it all?

Not what I\'ve read. More like 1500 for basic Lithium, and LiPo is a piece of shit:
\"\"The maximum charge cycles for most LiPo batteries tends to be around 300,\" said Thomas Bradbury. But even 300 recharge cycles is optimistic. Bradbury said that only applies to higher quality batteries. \"Many LiPo batteries will not even last for 300 charges,\" he said. The metric that matters most: internal resistance\"
https://www.thedronegirl.com/2020/05/24/lipo-batteries-last/

Or would you be cheating and discharging to 20%? So you get a battery a fifth of the capacity you paid for, those charge cycles are 5 times smaller.

> That means the Lithium battery lasts 25x as long, for 6x the price.

7x.

And I don\'t like this:
