Thinking about upgrading your boat to lithium? Twin Lakes Audio can get you taken care of!
Here’s a job we finished up a couple weeks ago on this Ranger Z518, and definitely one I enjoyed doing.
We replaced all 4 lead acid batteries with MillerTech 12V 135Ah lithiums, 2 for the outboard/electronics and 2 wired for the 24V trolling motor, plus a Minn Kota onboard charger.
We’d love to do more lithium upgrades like this. If you’re ready to make the switch, give Twin Lakes Audio a shout!
