Would You Recommend Lithium or Firefly Carbon Foam Batteries?

Question:

Jeff, great YouTube channel thank you! I've already learned a lot. I know you've been a fan of the Firefly Carbon Foam batteries, but would you still recommend this over upgrading batteries (and charger, and/or wires) to LiFePo4 (lithium)? I have a sailboat with 2 8D AGMs (200AH x 2) and was thinking about similar Amp range... c400-500Amps, which is a little more than I have now. Thank you for your comments.  - Anoolio

Answer:

Hi Anoolio, thanks for the feedback. Choosing between Lithium and Firefly depends on what is important to you versus cost. Generally, boaters that choose lithium really need lots of energy in a small volume and weight. They also want a Lithium battery for lots of cycle life and a fast recharge rate. Of course, all those benefits come at higher cost then Firefly batteries. As a boater, you also have to consider the implications of going to Lithium for your existing alternator, wiring, charger, etc...
