lithium battery failure while using livescope

[SawyerZ]

I was out yesterday and had the Livescope on while spot locked doing some striper fishing. We had been fishing about 3 hours and all of sudden, we lose power to everything on the boat. Attempted to crank the motor but everything was dead. Ended up getting a tow back to the house. Had a guy come check it out today and said my lithium battery was shot, and it appears the surge may have also blew up my 4 bank charger. Has anyone else had issues like this with their lithium batteries? Mine was just installed in May, so I assume it is covered under the warranty.

Only one battery for tm, livescope and engine start? At a minimum engine start should be it's own battery. Ideally you need 3-4 batteries for what you're doing. 2 on TM, 1 on livescope and 1 for engine start.

Lithium batteries have a charge controller. If they get to low the controller shuts the battery off to protect it. I would assume it won't charge now either? If this is the case you will need to reset the charge controller with another battery. Hook + to + and connect one the - terminals on a charged battery. Then all you do is tap the negative of the dead Lithium battery. All it take is a tap. Plug the charger back in and it should begin to charge. DO NOT SHORT THE BATTERY. positive to positive and negative to negative ONLY!
