I I'm sure that many of us are considering moving to a LIPO battery ecpecially for it trolling motor capabilities. The battery writeup is consistant with this use. What am I doing wrong. The voltmeter is the top left and the Tach is top right


settled on a Weize12.8 volt-100AH battery.,https://www.amazon.com/dp/B09F2LLMY3?psc=1...

, After chargingg up t he battery I installed it in the boat. direct swap, and ran it for several hours starting and stoping. It was peforming properly. Charging at 14+ volts. Got my Grand sons over and headed out for the day. As soon as I was above 2,000 rpm my GPS said it was over voltage and shut down! the voltmeter was all the way of to the right, only reads to 16 volts. Reduced speed to idle and the Voltmeter went back to 14.4 volts. I turned the GPS back on and its voltage was 13.8, same as the volt meter. I increased the RPM to 2000 and the GPS went into "over voltage mode" and shut down. The voltage was showing on its screen at 16.9. I idled back to the dock and tied up. Shut the engine off and restared it several times. No problems!!! I went home and got one of my older AGM batteries, swapped them over and went again without any issues for the rest of the day. What am I doing wrong????? The LIPO batter allows over charging, the AGM doesn't.The engine is a 2004 BF 40 Honda.

I believe the best way to charge your lipo battery is with a dc- dc charger. So your motor will charge the start battery which in turn charges your lipo via a smart charger.
