Edit-watt hours not amp hours
I’ve been digging around and thinking about diy or buying a rack battery like the EG4.
Here what I’m seeing. The representative “rack” battery is the EG4 at about $1500. Shipping and taxes not included.
The DIY option are cells from Shenzen Luyuan Tech, 4pcs EVE 304AH LiFePO4 (LFP) 3.2V Cells Battery (Fully Matched&Batched)--Genuine Grade A. Shipping and taxes not included.
EG4 type-$1500 for 4800 watt hours (wh)
= 31.25 cents per wh
DIY-16*$137 each=$2,192 + BMS (overkill at about $175 all in) + $100 (capacity tester and power supply)=$2,467 for 14,592 wh
=17 cents per wh
I’d appreciate any input on firming this up. Did I miss anything?
I’m thinking of picking up 32 (or 34) cells in Houston.
