    Have you looked into Lifepo4 batteries lately? Their capacity and deep cycle life are quite price competitive these days, even up here in Canada.

      Not like lately lately, prices were so bad for so long. Got a supplier you could recommend?

      I had hoped to start by building a pack for my small car using something like b-grade prismatics or good salvage cells from batteryhookup.com.

      Currently running 8kWh of lead-acid which as we know might as well be around 3kWh usable. Going to lithium would really make a car out if it, but the car itself is a weird old thing and not worth much so I don’t want to invest a ton into it.
