For sure, Powersync has nothing to do with PowerSonic. More likely, the name was chosen to confuse buyers into jumping to that conclusion. There are reputable LFP battery manufacturers out there, so there is no good reason to buy this.


Had to chuckle on this one. Ever wonder where the strange PowerSonic
name came from? It's shockingly similar to Panasonic, which actually
makes quality SLA batteries. I hope PowerSonic makes better lithium
batteries than their SLA batteries.
Well, if they do then you will be very pleased because I have used Powersonici SLA batteries in the past and have been satisfied with their performance.

I've been using PowerSonic now for about eight years in several different aircraft, including club ships. I purchase the 9AH version and, each off season, put them through a load test and follow their performance that way on a yearly basis. Average life is 4 seasons with one getting 5, and one getting just 3. I keep them on a float charge whenever not in use. They may not have the fancy name or the high price, but they do do the job for me.
