Need a deep cycle battery to put in a battery box to run my Engel Fridge. Am totally out of touch with the current hotness in batteries - should I be looking lithium? Or sticking traditional?
Depends what matters to you. Weight to performance, can't beat a LFP battery. But only if you are prepared to look after it properly. So manage the charge and discharge voltages basically, which is easy and not expensive.
Got a LFP setup as house battery on the boat. Replaced 150kg with 40kg for similar useable capacity. Hard to beat. But cost more up front.
