Hi, I am ordering 64 EVE LF380K batteries today. The bulk pricing is (and has been ) a bit messed up. The boss agreed to sell them for $149 as the price goes up if I put over 15 in my cart. Will be using overkill solar 48v BMS again. Was able to get shipping down to $450 (approx 800 lbs) by...

I have Carrier 18k BTU minisplits with a SEER around 20 (I'd have to check Costco). These use about 1800 watts at full power max fan. I don't care what the inverter/low power mode is because it may kick to high power (max 7200 watt inverter). Did the best I can insulating a concrete block house...

yeah.net or yeah.com? the dot com pulls up garbage. Wow how sketchy.

Great thanks!!! I'm totally off grid in Cabo San Lucas, MX. Can run three mini-split 18000 AC's from 9 to 5 but....I'm lacking battery power (48v setup). I'm just glad prices have not gone out of control since January 2022.

ok so how much for four cells not including shipping? I was hoping to have purchased a bunch of them by now but.....lawsuit has not paid me yet.

What is the approximate cost as of July? ( 1 krona = .095 $US)

If you don't want the 48v (which I assume is like Overkill), just PM me and I'll PayPal you the cost plus shipping to California. Did you get the Bluetooth add on? I'm using it one one battery pack now.

I'm having this problem on an OutBack FM80 using Overkill solar 16s. I had to watch the LED display and for some reason it is hitting like 60v or something....which shuts off my BMS. To fix, I just kept dropping the charging voltage (not on it now) at increments of .1 till it stopped. I've used...

I have a 12kw Outback Radian inverter. I'm running 2 AWG from four batteries to a Victron Lynx Distributor. I'll be running two pair of 4 gauge from the Lynx distributor to the Radian and two pair to my 7.2kw Flexpower. I never plan on draining anything close to that from the batteries at night...

Please let me know the latest prices plus shipping. I'm driving back to California next week and will be purchasing the same batteries.

Great to hear. I'll be ordering at least 32 in about two weeks when I drive back to the US (in Cabo). What have LiFePO4 prices done in a year? How much have they jumped up in price? This is for an off-grid house in Mexico.

You absolutely need to find out ASAP if you're allowed to build a house without being connected to PG&E. My mom was having Tesla Powerwalls installed and the guy said it was not legal to be off grid (who knows). If you're allowed to go off grid, congrats and you need more than $45k. You can...

What is the advantage having them come from China and not Texas? Shipping costs? I am located in California and need at least 32 Eve 280ah batteries. Why did you chose the 280 over the 304?

What is the difference between ordering from China or Texas? Price? I need 32 cells (to start with). Is LF280K the recommended cell for running off grid house? Just setup one 48v battery bank using the cells from my Amazon SHUNBIN using Overkill 16s BMS with Heltec equalizer/balancer based off...

I'll be pulling the trigger on 16 or 32 cells in the next two weeks. Everyone still on board that these are good cells at a good price? I just saw Tony's PDF and 8 cells for $1300 or so is a lot better than what I saw in Will's video from November (4 cells for $1100).

The Voc is fine with three Silfab's in series per string. Two charge controllers were used, one works. One charge controller went pop when I forgot to shutoff circuit breakers...nice arc. One charge controller got went during the last hurricane. Don't rate an item for 80 amps if it can't...

I have had 3/4 Outback FlexMax 80's die on me. My original intention was to oversize the number of panels so I could max out the 80 amps. Original configuration was 12x300w panels. I increased the panels to 18 per charge controller and panels are 300-370watts (3 per string, 6 strings). The...

I was going to a proper 20 degrees for Cabo San Lucas, MX. Then I went through a cat 2 hurricane last month. One of my panels (not mounted) flew 60 ft. Now I'm going to do flat and just add more panels to compensate. Try not to let much air get underneath then. Highest gust was 110 mph so I...

Wow, great video on marine grade. Thank you.

Including shipping per cell?

I'm looking at EVE 280ah and 16 cells are $1450 but shipping is $1370. Ouch.

Why are cell prices going up? What was the cost of a 280ah a year ago compared to now? I originally bought SHUNBIN off of Amazon two years ago because LiFePO4 plug and play was (and still is ) expensive.

Dismantling four 12v SHUNBIN Amazon LiFEPO4 batteries because two of the BMS's have burned up. This leaved me 32 large cells. 1. Should I use 16 cells per BMS or will running them 2p be ok? 2. The Overkill directions recommend 2 AWG for the positive lead. So is 2 gauge pos/neg is the max size...

Are 420ah the largest available?

I don't think it is a problem with 3.0 yet. My parents bought a house with pre-existing solar. They just had two Tesla Powerwall 2's installed and now have to sign a new NEM agreement which is 2.0. The 8 page document is requesting a new rate ETOUC (time of use which they already had). My...

I received my 16s BMS in a bit less than a month. Received emails when it was shipped.

They are a Canadian solar company. I have 36 panels from 300-330 watt. The 330 watt were under $300 last year. When I picked them up at a warehouse in Oceanside (ordered from multiple solar companies, same warehouse)...they said they were good panels.

bus bars were hacksawed aluminum.

Nice find on the busbar info...saved on laptop.

I didn't go with less than 1/4" because it wasn't the tinned copper bar. Ordered after another guy was ordering the same thing today and sent a message. Thanks.

Is .250 x 1" tinned copper acceptable for making bus bars? There is an option of .1875 x 1" but copper only. I'm pulling the cells out of of my SHUNBIN 12v batteries and making a 48v setup with Overkill Solar 16s BMS. Considering that this setup is 100 amps max drawing from battery bank, is 2/0...

I bought the supposed 500ah 12v battery from ShunBin. Just ordered an overkill solar BMS because I had four batteries in series. However, each battery is 100 lbs and the cells look much larger than anything I've seen in here or Alibaba searches. Each cell is I thin 10.5"x 9". No idea of true...

Well I'm very happy have too many panels. Although I probably won't be running AC in Cabo San Lucas from November to March...I'll still be running pool pumps, etc. No way I'll be maxing my inverter or charge controllers out during winter solstice.

are 280's/310's the largest available cells at this time?

My max voltage is 150v. When I plug three panels in series I get 105-108v so it's three panels per string max. (not sure your term overpaneling). 300 watt panels x24 is what I spec'd at (7200 watt inverter and 80 amps on a 48v setup). It sounds all perfect right? But those panels never make...
