Its time for me to start a project.
I just finished building a LiFePO4 car battery in a 3D printed modular housing
Now I think it's time for a Powerwall. I found two of these and I'm curious if you guys think these will be suitable for a powerwall for my application.
Here are the specs on these:
LIMITED STOCK! THIS BATTERY IS THE MOST POWERFUL BATTERY WE EVER GOT IN. THESE ARE ALSO WATERPROOF AND APPEAR TO BE USED ON NAVY SHIPS. SO THESE ARE THE BEST OF THE BEST. COMMERCIAL GRADE WORKING BMS, BUS BARS, SCREWS, WATERTIGHT ENCLOSURES, ETC ARE INCLUDED. ALL YOU NEED IS YOUR CONNECTOR WIRE. THERE IS A + AND - BUSBAR LABELED ON EACH END. WE INCLUDE THE SCREWS AS WELL TO FIT THE BUSBARS. ALL YOU NEED IS A PHILLIPS HEAD SCREW DRIVER. MAKE SURE YOU USE THICK WIRE. THIS MODULE CAN PUT OUT 90,000W OF POWER. WITH A DEAD SHORT AMP RATING OF 2250A. YOU ONLY NEED ONE OF THESE TO POWER UP TO 18 5,000W 36V INVERTERS AT THE SAME TIME. THIS IS THE EASIEST WAY TO BUILD A POWERWALL. JUST PARALLEL WIRE AS MANY AS YOU WANT. YOU WILL NOT HAVE TO WORRY ABOUT THESE CELLS GETTING HOT AND THE CYCLE LIFE IS 2-3 TIMES GREATER FOR LIFEPO4 THAN LITHIUM ION. THIS USES 96 A123 26650 LIFEPO4 CELLS. CHECK OUT THE SPECS BELOW. WE TESTED THESE ARE THEY HAVE AROUND 80-90% CAPACITY LEFT IN THEM WHICH MEANS THESE HAVE A LOT OF LIFE LEFT IN THEM. EACH CELL IS RATED AT 70A CONTINUOUS. BELOW ARE THE SPECS OF THE CELLS. CHECK THE PHOTOS FOR MORE DETAILS AS WELL. THIS IS A GREAT DEAL. I SEE THE PRICES ON ELECTRIC CAR BATTERY MODULES AND THIS DEAL BLOWS AWAY THOSE PRICES AND THE CELLS ARE ONE OF THE BEST OUT THERE.
THE DIMENSIONS OF THIS BATTERY IS 31" X 6.5" X 3". WEIGHT IS 19.55LBS.
The ANR26650M1-A is the first generation of A123 Systems pioneering 26650 cylindrical cell. This versatile lithium ion cell is suitable for a wide variety of applications and system designs. Proven performance in the toughest conditions, combining durability, reliability, and safety, the ANR26650 cell offers an excellent combination of price-performance.
Cylindrical Cell Primary Applications
- Portable high power devices
- Stationary battery backup systems
- Grid stabilization energy storage systems
- Commercial truck and bus hybrid electric vehicles (HEVs)
Lithium Cell Benefits
- Power: Over 2,600 W/kg and 5,800 W/L
- Safety: Excellent abuse tolerance and environmentally friendly
- Life: Excellent calendar life, 10X cycle life vs. conventional lithium ion
[size=x-small]1. Cell Dimensions(mm): 25.85mm(D)*65.15mm(H)
2. Cell Weight(g): 70
3. Nominal Capacity: 2300mAh
4. Voltage(nominal,V): 3.3V
5. Internal impedance(1kHz AC typical,m?): 6
6. HPPC 10 Sec Discharge Pulse Power 50% SOC: 200W
7. Recommended standard charge method: 1C to 3.6V CCCV, 45 min
8. Recommended fast charge Method to 80% SOC: 4C to 3.6V CC,12 min
9. Maximum continuous discharge(A): 70
10. Maximum Pulse discharge(10 seconds,A): 120
11. Cycle life at 10C discharge, 100% DOD: Over 1,000 cycles
12. Operating temperature range: -30C to +55C
13. Storage temperature range: -40C to +60C[/size]
I estimated my maximum loads for my entire home using a generator sizing calculator.
I currently only have a 60amp service. I have blown one of my main fuses on occasion in the past when using the dryer AND range, plus the A/C and possibly the hot tub kicking in to cycle. So this calculator seems fairly accurate and a little forgivingat 73amps max draw.
My goal is to never pay for peak power again. So I'm looking to power my home for 10-12 hours during the day with the possibility of adding solar panels in the future.
I'm looking forward to hearing the community's input on these modules and how you might implement them.
