Default Re: Just order 7 leaf batteries. Help please, canada

Brass? You want copper not brass. Preferably tin plated copper.

I get all my metals through either OnlineMetals.com or BuyMetal.com They have good copper and aluminum bars for a good price.

As for the BMS, I would normally recommend a REC BMS, but ZEVA would work just fine. You get what you pay for and those Chinese units have a high failure rate.

If you get a non-programmable BMS, tell the vendor you want to limit the charge to 4.05 volts on those Leaf cells. You'll loose 10 to 15 percent capacity at the top, but their cycle life will be greatly extended.
