125ah IONIC powering 3 lowrance carbons, AT1, point 1, nmea2k, and used for cranking.
I purchased the battery after reading about how lithiums providing steady, constant/full power until they are dead. Mine doesn’t do that. It clearly drops voltage on my screen as I use the battery. It acts like a normal acid battery as the voltage is higher when fully charged and steadily decreases as battery is used. Yesterday my voltage on screen was 11.6 at times.
Also, my voltage “bounces around” constantly all day. Seems like it should be stready and very little variance according to what I read about lithiums. If my battery is fully charged it will read between 12.6-12.2, constantly bouncing. Yesterday i went fishing with my battery not fully charged and it was bouncing between 12.0-11.6
And…… the reason I went out with my battery not fully charged is because I’m trying to drain it down into sleep mode and reset it because my Bluetooth app quit reading the battery. I’ve read that if the battery is drained fully it will reset the bms and the app will work again.
Any help appreciated. I do have good marine tinned, 10 gauge dedicated wiring straight to the battery. It’s on its own fuse blocks and not tied to boat wiring.
