BigBattery V.S. DIY V.S. TESLA?

Should I Build My Own Battery System

If you want to build a Battery Power System for the experience, that’s awesome! Just don’t do it to save money or time. After you buy all the parts and figure it all out, your total cost will be higher than our plug & play pre-made battery solutions ($$/KWh). By purchasing the parts to make our batteries in extremely high volumes, we are able to bring the price down to a point where.. Well.. It’s only worth building a Battery Power System if you really want to build one. 

Why not just Buy a Tesla Powerwall?
Our Home Power solutions use a much safer battery chemistry, at a much better price point and ship out within 48-72 Hours! If you want to pay for the fancy “T” be our guest.. But know that you will be waiting for a less safe battery chemistry with a lower battery cycle-life and paying a LOT more for it..

If you compare our LFP TREX vs NMC Tesla Powerwall, the TREX utilizes a safer, longer lasting battery at a fraction of the cost. Unlike TESLA, our products can be purchased without a solar system and ship within 48-72 hours!
