Hi everyone!
After discovering the youtube channels around june 2017 and this forum shortly after, it's now finally time to show what I've been able to do so far...
I enjoyed the idea of reducing my power costs by going solar, but most of my usage is not during the day so battery storage sounds like the ideal solution.
I started out collecting laptop batteries, but quickly found that a lot of them have quite a number of cycles on them and they'd show only a small capacity remaining.
Since I live near the border of Belgium and The Netherlands, 2 nice flat countries with lots of people using e-bikes, I started doing the rounds at the bicycle shops.
I've collected quite some packs, given away some as well...
I also built sort of a "charger board", mostly because I modded the OPUS chargers with 80mm fans.
It's powered by an old computer power supply and has 12 TP4056's for charging, 4 slots for reviving 0 Volt cells and 3 OPUS C3100's (3 slots have died, unfortunately).
After about 1,5 years I managed to gather2266 cells anda little over 1700 of them are 2000 mAh or more in capacity.
It took a while, at first 1 wanted 80P packs and then a 100P and.... Now I've settled for 60P, but built 28 of them rightfrom the go.
After using repackr, I had the values to go in each pack but some late nights later it seems I've made quite a few errors along the way.

So 28 packs on the table, each 136,3 Ah which gives 14 kWh.
I've also purchased:

I've also purchased:
- a MPP Solar PIP-5048GK (the latest edition)
- an ABB 160A DC breaker (eBay link)
- 35 mm cable to go between battery and inverter
- A Batrium WatchMon4 suite to complement it all
- solar panels to come when the battery system is operational
