I just watched an extremely knowledgeable person on youtube last night regarding setting up an entire solar system. I'm going to re-watch his videos again (the one I watched was from 6 or 9 mo ago... and about 36 min long (or something like that). He goes over EVERYTHING, thoroughly, with regards to what you will need, gauge wire, and more importantly (for me) the WHY you need this or that.

His youtube name is: cityprepping

EDIT: the company i contract for blocks youtube on their network so I wasn't able to link when I posted.

Here is the link to the video:

When I build lifepo4 packs, my goal is $100/kwh. This beats that! Impressive

Nov sale got 2 plastic one and 2 metal one. Metal one believe to be the same as DC House 165Ah even its label said 150Ah.

Ran full capacity test twice against each version. Here are the result. Plastic version has capacity 149Ah vs metal version capacity as 161Ah with 33-14A little over 0.2c.

Plastic version seams to have worse voltage drifting above 3.45v and ends with single cell over voltage protection above 3.65v to cutoff charging while metal version has very low voltage deviation among 4 cells even after 3.5v and ends with 14.35v set in bench power supply w/o single cell over voltage. So myself liked metal version more than plastic version based on charge curve alone.

The only con for metal is the weight 9lb heavier than plastic one. Metal case also can be stacked provided you put one 1 inch thick wood in between due to the handle on the top

Quote from motor-head :
one image shows 1920wh. how do they get that figure, since 12v * 150ah = 1800 wh.

is the voltage actually higher than 12v at the beginning of the discharge cycle?

thanks
12.8v

Regardless lifepo4 workable voltage from 2.7v to 3.6v, capacity calculated from its nominal voltage of 3.2v per cell, 3.2v * 4 * 150Ah=1920Wh.

I know it sounds like a stupid question, but how do you charge these kind of batteries? Do I need to buy one of those auto battery maintainers that are LiFePO4 compatible (e.g. battery tender) to charge this? But those kind of trickle chargers charge slowly. Is there a recommended AC charger that can be used to charge this battery indoors? Is it even safe to charge it indoors?
you do need a new charger. lifepo4 batteries max out at 3.6-3.65V. These batteries are 4 cels.. and you need a 14.4 Volt charger. The batteries can charge pretty fast, maybe 50a check specs but u will never go that high!

Get the bluetooth one it's nice.
Have mine for 6 months ago 100ah in my camper van works great!
can you enlighten me what else I need to use in my class C? my power fuse box says lead acid / lithium auto detect; could be literally take out 2 factory coach batteries (these are separate from engine 12v battery) and put 2 of these and get 300 AH?

If you know the answer or have any good reading or videos you'd recommend that I could learn from I'd appreciate it!

Previous comments have stated that it cannot be used as a replacement for the lead acid main starter battery in an automobile.

Can this battery be used to jump start a v6 engine? This battery connected in parallel with the lead acid battery.

I know that my 12V 120AH SLA battery for my sump pump is getting old, and this looks like it could be an attractive replacement. I have an UltraSump III controller which charges the battery and switches on a DC pump if the water gets too high in the sump (typically because the AC power is out). Simplest would be to replace the SLA battery with the Eco-Worthy one. I know it wouldn't get fully charged, but would there be any other problems?
More complex would be something that could boost 13.7V to an appropriate level for LiFePO4 charging but which cuts off when the AC power disappears. Even more complex would be to gut the UltraSump III and replace it with a PCB of my own design, but I don't have that much free time.

I can confirm dc house 165ah metal case capacity tested at 161ah -162 on multiple runs. The voltage is very balanced from top of charge to bottom.

On top of a charger, if you're only going to use USB c, an inverter is overkill. A 12v to USB c should be cheaper, and usually more efficient
https://www.amazon.com/Hapytrip-W...B0CGXF14Z4
Here is one I found on Amazon
You need an inverter. The inverter will have the house plug built in and 2usb plugs also built in. This is a good size battery so it can run some good high wattage things. Skimping on the inverter will prohibit you from running bugger things that could overload a smaller inverter. Inverters can be inefficient and draw downn on the battery also. Buy one with a remote and an efficiency rating above 90%. You want to turn it off when not in use.

Well ideally you would use a solar charge controller (20 - 30A) and a couple of solar panels.

I use a 15A AC charger [a.co] that's made for Lifep04 batteries when I get them new, just to top them off before adding to the solar array.
I currently have 2x200w solar panels and 3x100AH batteries powering a 2000W inverter in my shed.

Anyone know if these would work well hooked in series for a 48v Golf cart?

Just starting to look into replacing my Lead/Acid batteries and this seems like fantastic pricing.
Yes, but you need to confirm the sustained amperage output that your cart needs. The best setup would be 8 total batteries which would give you 200amps continuous output, and a very high temporary surge output

can i use it as backup power from my home electronics (modem /router etc) . What other accessories i need to buy, to charge from 120v outlet and give me 12v to 120v outlet too. I am thinking to keep my router connected to this battery all the time.
