Price breakthrough for LiFePO4 batteries

[Uncle Fester]

Just like I predicted.
These put the cells in a Tesla Powerwall to shame.



Just grabbed 4 and a few hours later the price dropped a further 10 bucks, crazy.
So they are now 284,99 each for a 48V system.
Being an Ebay member another 10% off until tomorrow.

That's a mere $1025.96 for REAL USABLE 5.12kWh !!! The 4 will fit in metal tool chest, like I keep the others and I can still carry them around, about 45kg.
With the Lead acid rubbish you would need to purchase 20kWh to get the same daily performance. What is that? 8-10 grand?

The deal with LiFePO4, apart from being the safest battery in the world is that you can drain them 90% and get at least 2000 cycles but if you only charge them up to 90% and discharge all the way down to 10% state of charge(SoC) you can double that life cycle number.
After that you have a battery that has 80% state of health(SoH) that still works fine for another 2000 odd cycles until it is 50% SoH, unlike Lead Acid which becomes almost instantly a massive toxic hazard to dispose of after it's 300 deep charge cycles or 3000+ shallow 20% cycles.
