going on from previous posts. I am also wondering if some other issue is stopping the posts as well. and i get tired from typing it all over agian.
I generally order between 3000kg to 4000kg at a time. the biggest order so far was a few years ago, around 6000kg in one hit. Thats a lot of money. I have to order a lot at a time to keep the price down. The current US AU exchange rate is very bad which make the cost in Australia much higher.
Cureent price for Thundersky Winston LYP is $1.86 per Ah.
Our new solar system battery.
48 cells x 300Ah x $1.86 = $26784
79 copper connectors x $5 = $395
Plus strapping thread bar etc
And initially, it will get 4 Deligreen balancers x $140 = $560. See how this goes. I had 12 balancers on the old pack. Thats a triple stack for 3 times the transfer rate.
The LYP chemistry is the same as the LFP except it has the Yttrium added which increases the voltage stability and increases cycle life. The LYP is said to be 5000 to 7000 cycles compared to the LFP at 2000 to 3000 cycles. The battery pack in EV Hilux is LYP and are now 6 years and 8 months. The LFP were taken out of EV Hilux at 5 years but probably should have been 3 years. These LYP in EV Hilux were fitted when the old LFP were taken out. I am not expecting the full cycle life from the LYP in EV Hilux, EVs are hard on batteries compared to solar. Already at 6 years and 8 months is shown to be better. Plus I travel long distances, many times a year, with multiple cycles per day with this pack. A number of customers have reported after many years on solar, their LYP batteries are still performing like they were new.
The old batteries, LFP, are a giveaway if anyone interested. The LYP are still worth a small dollar, any offers. The LYP are not as old. http://www.thebackshed.com/forum/ViewTopic.php?TID=2790&P=3
I did inquire about recycling. One place, Envirostream Australia, said they recycle lithium batteries, but i had to pay them, and pay the freight to Victoria. Freight is not cheap either.
