Re: Hypothetical Radar

Since the OP was specifically asking about a race, I assume the radar would be used full-time for tactical reasons. Weight would also be an issue, but it wouldn't make sense to spend on LFP batteries for a single race. Otherwise, installing LFP batteries is probably the best decision we have made, and best piece of gear added, to our cruising boat and lifestyle. Simply a game-changer on so many levels. Lots of bad information and practices out there, and fire/explosion myth is at the top. Overcharging them will likely ruin them, as it will gel and agm lead batteries, but easily avoided with normal charging practices like used with gel and agm. However, undercharging them is of no consequence at all, while it will quickly make slag out of gel, agm, and flooded lead batteries. Undercharging is probably happening on 80% of all boats equipped with lead out there, while overcharging is so rare as to make news when it does happen.

Morganscloud should not be used as a definitive source of information for anything. So much of that is uninformed, misinformed, or outdated opinion. Much is good too, but one should definitely exercise caution and seek corroboration of their opinions. As for choices most cruising boats are making wrt batteries, there is unfortunately a wave of conversion to LFP going on right now. To the extent that there are long wait times for supply. I say unfortunately because there is a lot of fly-by-night and snake oil sales popping up now, and many consumers refuse to educate themselves. Frankly, I'd be happy if everyone else stuck with lead.
