The lithium technology is now becoming easily accessible to general population. 3000 charge cycle expectancy is difficult believe, offering 10 times longer lasting usability than lead acid or AGM types, or up to 5-6 times more than first generation lithium ion batteries.

This equates to minimum 10+ years life expectancy, yet priced at par with high quality commercial lead-acid batteries.

This is fabulous and unrealistic deal, but I don't believe seller's claim. If they truly believe their hardware to last minimum charge cycle of 3000, they'd be accompanied with stated warranty accordingly, that is minimum 10 years free of replacement guarantee, that is to say, free battery replacement rights to purchasers if storage capacity degraded to industry standard of 60-70% of original specification.

This really may be a quantum leap jump in battery technology everyone wants, or just a hype to find a sucker. I'd tend to believe it be be later case, as I can't find warranty replacement policy that support its claims.

There still is many merchants selling over-stated lithium batteries in eBay. I do not believe they wanted quick income by cheating someone, but they really do NOT understand the underlying battery technology. I hope merchants in this understand the items they sell to public.

You must not be familiar with LiFePO4 chemistry.

LiFePO4 chemistry batteries have high cycle counts in the thousands. 3000 is a reasonable expectation for these batteries. Whether the manufacturer puts in quality cells is something buyer has to research.

anyone know of a Solar battery maintainer for a car battery? I have a car that is parked for long periods and needs a boost to start. I have a plug-in maintainer that works great, but most of the time the car is parked away from a socket.

There's been plenty of fires and recalls on these flexible solar panels. While they seem like a great idea, they need to be installed on something like corrugated plastic so there's air flow underneath just like there is with every other type of panel. Heat is the enemy. They also only last a couple years when rigid panels which are even cheaper than this deal usually come with a 25-year warranty.

do anyone use it for regular house? Or is it meant for boats, RVs?
ALBERTSVOICE SOLAR that's my youtube channel .. I have 55 watt EFTF panel on the dash connected to MPPT directly to the AGM keep the battery at full. Been like that since APR 2021 called that my SSG = Suv Solar Gen. I just built an AVSGEN portable unit it uses SOLAR CONVERTER takes 24V down to 12V @ 480W max. My 140 panels are ETFE type on my master window. Can't install them on the house then county comes after me with their BS. I am lucky where I live the Sun is strong from 7AM to 4PM IT take 6 hrs to charge my AVSGEN..

In my SUV MPPT kept the AGM fully charge I can run devices without the ALT gen. These panels on sale aren't that great. I am LENSUN panel but they don't make theirs just like TOPSOLAR wants $149 for 100W ETFE panels give you near 85W and 23V. I use in-line MC4 fuse. I do not like these LifePO4 batteries have a bad BMS sent over 20 back to Amazon. They all arrived DOA. I say why you sent me DOA batteries Amazon.

Is there a way to use solar panels without annoying batteries? We get tons of sun here, but what turns me off is those batteries that take up space, are a fire risk and need replacement sooner or later. Sure I wouldn't have supply at night, but maybe it can just supplement the power bill somehow?

Yes, you would essentially just use a grid-tie inverter.

You don't need to use batteries with solar if you are connected to the electrical grid. The major downside to not having batteries is your electricity will go out whenever the grid does.

Amazon has this 100Ah LiFePO4 for $360 ($400-$40 discount)

https://www.amazon.com/LiFePO4-Ba...B084DB36KW


Is there a major difference between it and the HQST battery?

Quote from Symber :
I vaguely recall Will saying something to this effect as well. IIRC (and that's a big assumption lol) it was for a particular battery he was tearing down at the time. Maybe the EG4?

I will say, however, that lifepo4 shouldn't have this drawback that other lithium ion chemistry has in the past (like cell phones). The lifepo4 chemistry is capable of complete discharge without harm to the battery. I think it's likewise also unharmed by fully charging.
I agree, the battery chemistries are different. My only reason for mentioning a phone battery was as a point of recollection.

I believe Will Prowse was making the point that you can safely charge and discharge the full capacity of a LiFePO battery 3000 times before hitting the 80% capacity deterioration marker. But it is also possible to extend the battery's life if you stay within the 80% / 30% parameters. This allows the battery to get 10,000 cycles before reaching the 80% capacity deterioration marker. The caveat is, you need two batteries to deliver the same total amps delivered in this scenario.

I think amazon one is better, amazon one provider 5 years warranty and it supports serial or parallel connection. HQ one does not support serial connections.

they'd need 3 of these 100Ah batteries per hour, assuming a 3.5KW unit running non-stop.
yeah, but how long would that run? 4 hours?

The battery comes to $3.65/Ah. If you are willing to wait for a slow boat from China and assemble the battery/BMS yourself you can get as low as $2ish/Ah.

I used these to build a 280Ah system.

Is there a youtube video or website you recommend for learning how to build the battery?

As a solar noob, is the flexible solar panel something I can connect directly to one of those portable batteries like the Jackery Explorer or Golabs? Or do I need one of the MPPT to do so safely?

I don't get all you said. My hybrid cars do effectively on gas already. I guess it's not the solar panels goes on roof I guess?

Generally, yes, for the larger batteries anyway. The battery needs to have aa 18V or 19v input. For the portable power it will have an internal MPPT so you don't need one. Check your user manual.

I have one of these at 633Whr and $299. It's a good value and includes the MPPT: https://www.amazon.com/gp/product/B08YRFLSR3

Check the dimensions. Depending on how you use it, a folding panel might be more convenient. I have a couple of these but they were lower priced when I bought them: https://www.amazon.com/gp/product/B089MCW39W
