Batteries

Watch all of Will's videos on current LifePo4 batteries. You might find them informative and help you make your decision.
I recently went through the same process to upgrade my existing LifePo4 batteries and went with the MidNite Solar MNPowerflo5 for my set-up.
MidNite also has a wall mount 16kwh product. More $'s that the unit you are looking at but from a very reliable and reputable company with solid US based customer support.
There are a lot of options out there right now...choose wisely for the right reasons.
 
I am looking into making a off grid system, found this battery and wonder if any one else has got it and if it is any good, it is 62KWH! https://batteryevo.com/product/48v-king-kong-2/
What are other good options for batteries that are reasonable? Need at least 60 KWH for no sun days!
I’m honestly wondering if anyone has ever done a warranty claim and had luck with these guys. My personal concern is that these are not that cheap compared to other stuff available and questionable warranty.. I’m not super familiar with midnight but that or eg4 or something with real support might be worth it. 4x16 sounds like it would meet your needs and if one unit dies it’s not game over
 
Something I believe anyone making a battery purchase should consider:
1) Does the battery/BMS have any kind of external monitoring capability such as Bluetooth (phone app), RS485, CAN or RS232 (computer or phone based, I prefer computer).
2) Does the Retailer and/or manufacturer provide a link to download the phone app or computer based software.
3) Does the battery provide "closed loop" communications to an Inverter and if so does the battery allow you to select a protocol that is compatible with your inverter. You may or may not want to use "closed loop" but don't lock yourself out of the option.
4) Download the app and/or software to make sure you can load and run it.
5) Does Solar Assistant support the battery/BMS. Although for many this is not that important as long as you have other external monitoring, it would be nice to know.
6) What BMS is the battery using. Knowing what BMS is installed will allow others on this forum to provide input with respect to BMS performance and monitoring capabilities. The retailer/manufacturer should be more than willing to provide you with this information.

External monitoring in my opinion is essential and a "must have". It is not if but when you have an issue with the battery you will need the monitoring capability to help resolve the issue.

Ask them to quantify what “reasonable capacity” and “guaranteed to function” means in their warranty literature.

Yeah, some people need their hands held crossing the street, while others base jump. Just because you need to have your hand held, does not mean EVERYONE needs to do the same. Waste your money on those overpriced batteries. These systems have worked for decades and now there are you battery elitists trying to claim no system is safe without a battery with 10 cables running out to monitor them. Might as well run a cable to the toilet and monitor that too. Ridiculous and I am getting pretty annoyed with these posts.

Sniffle..... sniffle.... sob
 
No Answer!
Could you give a reason why you would not recommend? I am just curious of the cons of them.
A few highlights from my experience after purchasing a walrus last summer.
Once you buy it you’re basically on your own.
When searching youtube for any information 97% of the many many many videos are their own, telling you how great they are.
Further the fact that sales and tech support are the same 2 guys is very telling, and for most tech questions I’m told they will have to get with their engineers and call me back. I’ve also been encourage to email them…. I have been called back once and never had an email returned.
When my system wasn’t performing a portion was returned to CA for service and while it was returned working they offer no documentation of what service or repair was done.
The small active display on my unit only offers very limited real time data, that I’ve been told isn't accurate. With no history retained when there is a hiccup or event there is no record of it or of what was happening at that time.
They do have an app (that is next to impossible to connect to) but there is no documentation about it, what or where to find information or how to navigate through it. That’s from one time I happen to connect to it for a few days.
Did I mention there is no remote monitoring and no logging of information.
No information on the bms, mppt or inverter is available.
Lastly the less than generic bms, mppt, and inverter can’t receive software or firmware updates.
I will say their masterful use of caller ID to avoid my calls is exceptional.

I don’t think I've ever read of a positive customer experience.
ymmv
 
If I'm doing the math right, that's a really good price. But, 1230lbs, wow.... Personally, I don't like the idea of one battery. I've got 6 batteries for 1854Ah/95kWh. If one goes down for any reason, I have 5 batteries still working. At worse, I have to replace 1/6 of my investment.
 
No Answer!
Have yo done a search on this site using Battery Evo as the search term?

" no claim of UL certifications and no mention of the NEMA rating for indoor or outdoor."

Lawsuit by LG?


Good Luck, couple of thread links for you. If you do buy that big battery let us know how it works out. It will take some decent sized equipment to place it.

Thank you for using your 7th post to tell us to get off of you lawn.
 
Everyone who knows that lf280's exist is building with them right now for the simple fact that they give amazing value and performance. 6 packs give you ~90kwh for about $7000, which is about what most people want to live comfortably and is under budget when compared to every other option.
