Why choose LiTime 16V 100Ah fish finder battery?

LiTime 16V battery was originally developed from customer feedback on the performance of fish finders. Using a single battery on your fish finder, especially a 16V LiFePO4 battery, provides a more stable power supply. It effectively isolates interference from other devices on the boat, and prevents affecting the fish finder's imaging and sonar signals. The stable power is crucial for maintaining the optimal performance of sensitive equipment like forward facing sonar and marine electronics.

What are the advantages of 16V batteries over 12V batteries?

With longer running time, using a traditional 12V lead-acid or LiFePO4 battery, the voltage drops and results in erratic imaging. LiTime 16V LiFePO4 battery provides a higher voltage level to stabilize and maximize the performance of your fish finder.

1. Better Clarity & Stronger Singal: It not only enhances the clarity and brightness of the electronic display, but also produces a stronger signal for greater penetration and clearer returns from underwater, further improving the accuracy of the sonar image.

2. 25% Longer Runtime: 16V 100Ah LFP battery has higher power than 12V 100Ah LFP battery, which offers 25% longer running time to meet your all-day fishing.

Will a 16V 100Ah Lithium battery damage my fish finder?

Not at all! For the same power, a higher voltage results in a lower current. It's well known that more current generates more heat, which is the enemy of your electronics. Therefore, a 16V battery will produce less than 20% of the current as a 12V battery, resulting in less heat to reduce the risk of overheating.

Example:

A 7-inch graph is rated for 2A at 12.8V. If upgraded to a 16V battery, and maintaining the same power of 25.6W, we can calculate the current at 16V based on the power formula:

I=P/U=25.6W/16V=1.6A

Therefore, the 16V battery will not produce more heat to damage your graphs.

Is LiTime 16V 100Ah LiFePO4 battery compatible with my fish finder?

LiTime 16V LiFePO4 battery is compatible with most fish finder brands on the market, including Lowrance, Garmin, Humminbird, Raymarine, etc.

Do I need a special charger for 16V 100Ah LiFePO4 battery?

Yes. You will need to have a charger that is specifically for 16V LiFePO4 battery. It is not compatible with chargers for 12V, 24V, 36V or 48V batteries.

Can I connect LiTime fish finder batteries in series or parallel?

LiTime 16V 100Ah lithium fish finder battery supports max. 4 batteries in parallel conncetion. Please don't connect the battery in series.

When connect the battery in parallel, please make sure:

They should be identical batteries with the same capacity (Ah) and battery management system (BMS) rating (A).

They must be from the same brand, as lithium batteries from different brands have unique BMS configurations.

They should be purchased within a close timeframe (ideally within one month).

Is LiTime 16V 100Ah lithium battery suitable for ice fishing or cold areas?

Of course! LiTime 16V 100Ah battery is equipped with a self-heating function that allows the heating to start at -4°F to 41°F and stop when it reaches 50°F. This ensures that the battery operates at a safe temperature state and fully utilizes its performance. If you need a starting battery, learn more about LiTime marine starting battery.

3 fish finders one 16V LiTime Battery

I purchased a 16V LiTime 100 AH battery to run
One Garmin Ultra 2 16” and two LOWRANCE 9”
fish finders.
I wasn’t sure if it would be enough amps to run
three units.
I was wrong. The battery worked flawlessly.
I fished two days, 10 hrs each day.
According to the Bluetooth, the battery still had
63 amp hours left.
I was surprised. It was well worth the price.
Would I recommend this battery?
YES!!!

Well my problems of the cranking battery going dead are solved!! Garmin live scope was draining

Well my problems of the cranking battery going dead are solved!! Garmin live scope was draining cranking battery in around 3 hrs or so I would have to jump cranking battery with trolling motor battery and let engine idle to get some charge on battery! I went out last weekend and only went through 20% of fully charged battery! And that was 10 hrs on the water.

So far this has been an excellent decision

So far this has been an excellent decision. Runs 3 12” Lowrance screens and active target for approximately 8hrs and will still have 60-70% of battery with voltage around 16.2-16.4.

Just installed this battery in my boat to run all my electronics! Connected the battery to the app and my phone, very happy with it so far!! Haven’t had the opportunity to run it for a long period of time yet, but will do a follow up after the season.

Great for Fishing Electronics

I love having the clean 16V power dedicated to my fishing electronics. Alot of people think this will give you a clearer picture. This is not true! But what it will do is give you higher voltages that will help account for voltage drops the further your electronics are away from your battery. The best thing you can do for a clearer picture is have quality, marine grade wiring!

Graphs worked great!

I have 2 HDS Pros, 2 Active target 2, 1…3-1 transducers running on the 16v 100ah. Everything worked perfectly. I only used 40% of the battery in an 8 hour tournament with everything running!
I highly recommend this battery!!!!
