You can buy it here: www.weizeus.com/?ref=WILLPROWSE Just a heads up, this company has not responded back to me for a week, and they do not have a website. It may be cheap, but as always, you get what you pay for. What use is the 10 year warranty if they do not respond to emails? I would rather go with a server rack pack or SOK, but it is up to you. I think this battery is perfect for people on a tight budget that need low temp charging protection. Let me know what you think below!

My use is for my electric RYOBI riding lawn mower. Originally came with 4 12 volt 48 amp ACID BATTERIES.. lasted about 2 years .Now after 20 minutes of run time have to recharge to finish mowing.. Hope lithium batteries will last at least the 10 years they state (with proper care).... Will update in a few months of use once they get put in my mower....THANK YOU..

Another excellent Will Prowse review on a low cost battery. I think I will stick with the SOK 100AH batteries for my camp trailer and off grid use applications.

Lipo4 battery tech continues to drop in price and build quality continues to improve in the low to mid range priced products!

Glad to see this as I bought 2 of these for my trailer in April. Unfortunately I paid $500 ea instead of $350 :(. So far they have performed very well. Only down side is you never know when they are going to go dead while dry camping as they always put out the same voltage and the battery monitor for the trailer always shows them as full. To resolve this I bought a Bluetooth LiPo monitor so I can monitor the capacity of them and know when to fire up the generator for charging.

I can charge it to 14.4 or so, but they quickly come back down to 13.2. I'm not an expert but maybe this is how they claim 7000 charges which, i guess, is a good thing with my application.

It looks like they increased the discharge rating to 100A/200A (3s) and have not updated their images so that was a pleasant surprise! Took a charge no problem with my NOCO Genius 2x4 on the lithium setting, but the final voltage was 13.8 and its in the maintenance step. Not sure if that is normal for NOCO or not but it is a low amp charger so maybe that has something to do with it. I normally use the charger just to maintain as we have long runs in the gulf and the batteries are typically topped off on the way home. Thoughts? Tested out of the water and so far so good.

These batteries look well built and affordable...And, are the price of the AGMs I was looking at. After computing my power consumption needs, I think I need about 1000aH of storage. $3500.00 vs $10000 sounds a lot better. Edit: I just watched your EG4 video. You can also get those in 400aH 12v for 1499.00. 100.00 bucks more, but a more simple installation and waterproof. Probably a better way to go if you need a bigger bank for a marine application as I do.

if you compare wet cell battery capacity to LiFePO4 you will find wet cells only output roughly half of the rated Ah, so half the Ah in lithium will suit you imho

[@christianhope1089]

Cells are available on Ebay for 280 or a best offer. The only problem is no support the site works sometimes and is showing out of stock. So as Will discussed the price seems good cells cycle life is less than the redodo cells. But which also have a promotion on ebay for 288.00 yet there has no low temperature or self heating in there cells, so is it necessary for keeping the cells warm??? Will was saying insulation helps the cells stay warm will have to do a test. Thanks again, Will!

[@jfwatson10]

Has anyone tested the over discharge voltage on this? If so, at what voltage did it actually cut off? I'm unsure the bms actually has a low voltage cutoff. The amazon page says 10.8v, but I've ran it down to 10.4 with no cutoff.

[@Kycirion]

Your inverter should have an auto-cutoff. If it doesn't you should upgrade.

[@wek66]

I just recieved the FPLI-12100Ah today. Cont./Peak discharge on battery label is 50A / 100A (3s) Whne did this change? Now it is only .5C? This is half of what they show on their listing. Sending it back.

[@rtpman1953]

Even though Will hasn't received a reply from the company, the build quality and the fact it has hot/cold cutoff sensors led me to buy it. I was looking for a 50ah one but for the price, why not? I have three Battle Born LifePo4 batteries so I'll see this performs. Thanks for a thorough review.

[@smertz04]

You used these much yet? Any update on performance?

[@rtpman1953]

@@smertz04 I've used it quite a bit. I had an extended power outage and used it daily (charging via solar), to run lights and low current items through my inverter. Also, I'm a ham and use it to power my HF rig in the field. Just keeps on working.

[@TheFieldLab]

Will...not sure if you have ever covered this before - it is easily possible to add a temperature sensor to a BMS that doesn't have one? It would seem to me that any BMS would already have that circuitry in place.

Damm, I just bought a Chins 100ah battery from Amazon. It's a darn good battery and will be buying another one on the 1st of the month. But these weren't priced this low earlier, to bad.

Just put two 100ah chins on my trolling motor. So far so good especially at $359 each

50 dollar coupon on amazon brings it 350

[@paulpietrasiewicz5316]

Iv been watching your videos trying to educate myself on lithium batteries, the answer I can’t really find is what causes them to thermal runaway “ fire explosion “ could you possibly do a video on that subject? Much appreciated thanks for all the knowledge you supplied thus far thanks again

[@carexpert5945]

Could this work on Ryobi Riding Lawn Mowers, which need 48V, 4 batteries in series? It could be a game changer.

[@stevea1184]

I'm looking for an easy replacement as well. I think the peak current draw is about 100 amps with more of a constant draw around 50 amps if that helps.

[@christopherlaboy9377]

I tune into Will's video's like I did for the Goonzquad Rebuilds... I couldn't wait to see the next video. Now I'm still sold on the EG4 for the price, and the SOK's for the RV. Oh and Will - would love your take on the new Rivian.

Not $350 anymore, showing $399 now! not a bad deal nonetheless!

[@cristianhernandez4614]

I did check to use the coupon, but if you buy more than one, coupon applies only once, so discount price is only on the first one. Like I said, not a bad deal nonetheless!

[@lowrads3653]

When we are amazed that we can store a dime's worth of electricity in $350 worth of hardware, it amazes me that we are even still at the discussion stage of linking up the disparate power grids. Sure, those high voltage lines cost a couple of billion dollars, but we squander that on projects that don't have anywhere near the same level of payback.

[@slchang01]

True...The costs may never be falling to the point that average Joe is willing to pay in this case, because not many people live in off-grid area, or on RVs...

Si I had ordered the Time US B 95Ah and without even hooking it up, or unpacking it even, Saw your review. So I'm jumping on this Weise on Amazon $399 currently with a $50 Coupon $350+Tax as of this post. Will be running (2) 100w Solar panels, 1000w inverter, a garden irrigation pump and some lights, charging 20v tools, etc...

The price is $450 now on Amazon. When I add to my cart, the price drops to $399, but I don't see any "activate coupon code" button anywhere.

As always, thanks for your reviews. Very interesting indeed. Have you ever reviewed a Digimarker battery? I understand they are trying to compete against Renenergy now in my country.

[@shondorc3703]

I just recently had one of these fail after 8 months. I tore it down and found about a half inch of water inside that damaged the bms and caused corrosion. Have you ever seen water in one? Maybe a bad seal around the terminals. It was in a vented battery box on a travel trailer. I need to prevent this from happening again.

[@fvrrljr]

laughed chuckled giggled along with ya, your excitement was contagious. why they don't respond to your email ? if made in china they probably want nothing lost in translation before they give you a replay. or they know you and actually are shocked themselved that they got it right and *Will Prowse* APPROVED LOL

[@brettbolen]

I saw this battery for $299 USD on amazon. This was a positive review, and it's even cheaper now. I have two in series. Can I use a different 24volt battery in parallel with this set, or do I need to keep with the same brand ( and hope nothing has changed in the last year).
