I ended up going with a 40Ah LiFePO4 battery (~10lbs). Pricey, but I think it is worth the price given the capacity to weight/physical size ratio. I mulled over it for weeks and finally committed, I’m happy with the decision.

I’m probably going to do a little write up on my electrical at some point as I found this to be one of the more ‘interesting’ and perhaps lesser understood/discussed topics. Though, @mpilone’s write up here was very helpful and informative.
At any rate, would love to learn more about your setup when it’s all said and done. 🙂
