Reasons You Must Have 16V Battery

Unlike 12V battery, LiTime 16V 70Ah LiFePO4 battery maintains a higher voltage level, so the fish electronics​ remain in an ideal state for 50% longer run time. When power for the screen, radar (30W) and sonar (20W) at the same time, the 5 inch screen (1A) set can run for 17.8hrs, 7 inch (2A) set for 14.7hrs, 9-10 inch (3A) set for 12.6hrs, 12 inch (4A) set for 11hrs, and the 16 inch (5A) set for 9.7hrs.

LiTime 16V battery significantly enhances the clarity and brightness of your fish finder's screen, allowing to see critical details in real time. The improvement is crucial when using sonar technologies such as Garmin Livescope, Lowrance Active Target, and Humminbird Mega Live, as it allows for superior imaging and more accurate fish detection. Additionally, the increased voltage level improves the transducer's return signal for clearer side, down and forward imaging. It means you can identify fish and underwater structures with unprecedented precision, giving you a tactical advantage on the water.

16v70ah

So far so good. Battery doing an excellent job on running active target, lowrance carbon 12, and my rite hite turret. I’ve fished three days since installing and haven’t gotten below 62 % charge on the battery on any of the three days. Clarity seems to be as expected. App is easy as well. So far very pleased.

Perfect battery for Livescope!

The 16v battery has been a solid upgrade for my Garmin marine electronics. I’ve noticed a clearer return on Livescope and more consistent voltage overall. It’s also my first time using a battery with Bluetooth, and I have to say, it’s pretty handy. The app is simple to use and gives me valuable information at a glance...state of charge, amp draw, temperature, and capacity. Will opt for bluetooth capabilities in the future!

Switched to this LiTime 16V battery, and I can already tell the difference! The image clarity is far superior, and the battery lasts much longer.
