Yeah, tbh, the hardest thing for building a custom E-Bike battery pack is the ridiculous prices and downright unavailability of cells! Best I can get are 32700

Best I can get are 32700 LiFePO4 6000mAh cells for 5 Euros each... A prebuilt Li-Ion Chinese pack with an extra 2Ah is just 30 Euros more than the cells I would need alone (housing+BMS cost not included). Just sad.

- skohan 5y agoIdk, cells are commodity priced, so currently I think you just have to bite the bullet and shell out a couple hundred bucks if you want to build a battery. Used cells are also an option, and there's some really good ones out there. Anyway Li-ion and LiFePO4 cells are going to seem cheap once solid-state cells hit the market.
- sudosysgen 5y agoNah, cells aren't commodity prices, not even 18650 and certainly not anything LiFePO4. If you establish a relationship with the factory or a supplier you can send prices crashing down.
- namibj 5y agoMaybe because typical Li-Ion 18650 cells are significantly cheaper per Wh than LiFePO4?
- bserge 5y agoSadly, no, 18650's cost the same for half the capacity. Likely because they're in high demand right now and car manufacturers have hogged up the best of them. Hence, LiFePO4, heavier, lower voltage, less capacity, but also safer tbh.
