And here's what I've purchased to build my battery - note they're all available with prime shipping, except for the BMS, which probably won't arrive in time for the first build day. The battery I'm building is 48v, or 13S (13 cells in Series). For other voltages, you might find a BMS available with faster shipping.

Introduction

Challenges

Solar PV panels are inexpensive and durable. As are the power conditioning electronics. Batteries, however, are expensive, prone to failure, and often discarded as trash. Can we reduce trash output while solving our expensive battery problem?

Chemistries:

  • Lead acid
  • Lifepo4

Approaches

Recycle batteries from the trash stream to build new, high capacity, long lasting battery packs.

Battery (Recycled 18650 lipo cells)

Rationale:

Single battery system from tools -> teslas. I'll be bringing these tools in with me, to work with:

And here's what I've purchased to build my battery - note they're all available with prime shipping, except for the BMS, which probably won't arrive in time for the first build day. The battery I'm building is 48v, or 13S (13 cells in Series). For other voltages, you might find a BMS available with faster shipping.
