I am Bostjan and I am from Slovenia E.U.
About year and something ago I have started my Diy powerwall...
Inspired by HBPOWERWALL so most of my pack's are built like HB..
Now I have together 230ah in 14s configuration... that gives me around 11and something kw usable 10kw...
Balancers are like in uk powerwall....and are quite good

Nice setup

And more I have looked Peter HB powerwall more I was thinking lead acid batterys are no go.....
So li ion are way better option....
Not need to be fully charged every day and capable much more than best lead acid batterys and eventually cheap are also..... [emoji106]

Thanks! Yes Sweden here :)
I try to make them as often I can :) The day i can skip some hours working and get going with the youtube i will spend more time on that :)
 
Well done, like the way how you are paralleling the packs.
Can you take a foto a bit more close up to the connecting bars?
 
Ok no problem.....[emoji106]

FAKE

so much FAKE. Most of those out are users with 1-10 reviews and will be closed a week later. Opus cost from 25USD and up
 
Many have... None have recieved any yet :)
How many reviews does the seller have? Did you check the review text from people?
 
My test equipment......

One liitokala is for cycling purposes....

also opus to determine ruff capacity....

Real capacity measurement is with SKYRC MC 3000 and is quite accurate..... [emoji106]

First 3 liitokala's are only for top charge the cells....

Last liitokala have first cycle
Second cycle is opus.

Liitokala is also for cells that have low voltage around 0.5v/cell that are changing with small current easy...

Cells that heat up are separated to cool down and tested again if they heat up again then are going to recycle bin also cells that are lower than 1000mah and cells that can not hold the voltage...
