![Power shelf for solar batteries (18650)
DIY build of Power shelf for my Valence 18650 LiFePo4 packs.
SUBSCRIBE!
More information below!
The shelf is built in such a way that it hangs from the wall. Yes it does hang! The reason is that the floor on this 2nd floor is not created to withstand the weight and the beams under the floor is going the wrong way.
The wall itself will easily take the weight in both directions (Twist and down-force)
As of this video this shelf have been up and running with all its weight for some time and it works great!
Its currently holding 48x12V valence packs!
Neerd facts:
19200 18650 LiFePo4 cells
each cell holds 1400mAh of charge at 3.3V.
Total of roughly 88kWh
Weight: 864Kg
