Great to see that one of the largest vendors of lithium batteries has finally got wise to the fact that when used on boats, lithium batteries with an internal BMS must be able to communicate with external devices and the user to be safe and compliant.
That said, Battle Born are making a lot of noise about the phone app (user communications) but are ominously quiet about CAN bus communication, which is the best way to manage a safe and functional marine installation.
However, given that Dragonfly, the parent company of Battle Born (not to be confused with Firefly Batteries), bought Wakespeed last year, hopefully Al Thomason, designer of the best alternator regulator out there, the WS5000, will pull levers behind the scenes to make sure they actually do this right, rather than just produce a pretty phone app to bamboozle the non-technical.
One other point, Battle Born are making a big deal out of now being ABYC compliant with this announcement, but kind of glossing over the fact that, as I read the standard, all of the tens of thousands (guess) of batteries they have sold to yachties over the years without these features are not compliant.
I wonder how long it will be before insurance companies start requiring ABYC E-13 compliance before renewal? Could be a lot of secondhand Battle Born batteries looking for a home, and some very pissed off boat owners.
Seems to me that the very least Battle Born should do is offer a very nice discount on the new batteries to anyone who bought the old batteries, say in the last two years. Some sort of trade-in would be even better. Heck, maybe they could even upgrade the old batteries with the new communications technology.
Anyway, moral of the story: Don’t buy batteries with an internal BMS that can’t communicate with charging sources or warn you before things go wrong.
