Experience reliable energy on the water with the LiTime LiFePO4 batteries for fish finders, echo sounders and fishing boats.
These lightweight and safe lithium iron phosphate batteries provide constant voltage so that your fish finder delivers precise data – even on long trips.
Discover high-quality fish finder batteries and 12V fish finder battery solutions based on LiFePO4 – ideal for boat fishing, ice fishing and belly boats. Also suitable as a compact, high-performance option Batteries for electric motors in mobile use.
Whether weekend fishing, when using a Trolling Motors or on longer boat trips – LiTime batteries ensure long runtime, low weight and absolute safety.
Ideal for anglers who value performance, mobility and weather resistance.
LiFePO4 batteries offer the perfect combination of performance, safety and efficiency – ideal for use on water.
Compared to conventional lead-acid batteries, they deliver a constant voltage, so that your fish finder delivers precise measurements without signal interference.
Thanks to their low weight They are particularly suitable for belly boats and smaller fishing boats, where every kilogram counts.
Furthermore, they impress with a up to three times longer runtime, faster charging and significantly higher cycle stability.
The integrated BMS (Battery Management System) Protects against overcharging, deep discharge and short circuits – for maximum safety, even in wet or cold conditions.
LiTime also offers winter use Low-Temp and Self-heating models, which reliably supply energy even in sub-zero temperatures.
This way you always have the necessary power for your fish finder, trolling motor or lighting – whether you are on the lake, at the sea or ice fishing.
Not every fishing trip is the same – and the energy requirements also differ significantly between a compact fish finder, a fishing boat with an electric motor, or a multi-day trip.
To help you find the right solution, we have compiled the most popular use cases with the ideal capacity recommendations:
| Deployment scenario | Recommended LiFePO4 battery | Advantages & Notes |
|---|---|---|
| Fish finder/echo sounder | 12V 20Ah – 50Ah LiFePO4 | Compact & Lightweight, delivers stable voltage without signal interference – ideal for echo sounders, GPS & Lighting. |
| Fishing boat with trolling motor | 12V 100Ah/24V 50Ah | High discharge rate & Long runtime for motor and fish finder simultaneously. |
| Winter- & Ice fishing | 12V 100Ah Low Temp/Self Heating | Reliable energy supply even in sub-zero temperatures. |
| Smart Monitoring Users | 12V 100Ah Bluetooth Version | Monitoring of voltage, capacity & Real-time temperature via app. |
| Multi-day tour/Solar powered | 24V 100Ah or 2× 12V 200Ah | Extra capacity for longer operating times, compatible with MPPT solar chargers. |
LiTime offers not just individual batteries, but complete energy solutions – perfectly tailored to your area of application.

To ensure your fish finder and fishing boat battery works reliably in the long term, it's worth taking a look at proper handling and maintenance. Here you'll find the most important practical tips and further instructions.
Content structure:
Correct installation on the fish finder and echo sounder
Use correct cable cross-sections and secure connections to avoid voltage losses.
Optimal charging and unloading
Use only LiFePO4-compatible chargers and fully charge the battery after every trip.
Storage and operation at low temperatures
At temperatures below 0 °C, use low-temp or self-heating models and keep standard batteries above freezing if possible.
Regular maintenance and safety checks
Check terminals and plug connections for corrosion and ensure the BMS indicator is functioning correctly.
1. What battery size is ideal for my fish finder?
That depends on your device's power consumption. For most fish finders, one is sufficient. 12V 20Ah to 50Ah LiFePO4 battery, which offers approximately 8–15 hours of runtime.
2. Can I operate my fish finder and trolling motor with the same battery?
Yes, as long as the battery has sufficient capacity. We recommend 12V 100Ah or 24V 50Ah Models that provide enough power for both devices.
3.How long does a LiFePO4 battery last in a fishing boat?
A high-quality LiTime LiFePO4 battery offers over 4000 charging cycles and, with proper care, can be used for 8–10 years – significantly longer than conventional lead-acid batteries.
4. Do LiFePO4 batteries work in cold weather or in winter?
Yes. For temperatures below 0 °C, please select our Low-Temp or Self-Heating These models deliver reliable performance even in sub-zero temperatures.
5. Is a special charger required?
Yes. Use only LiFePO4-compatible chargers with the correct charging voltage (14.4 V). This ensures the battery remains safe and powerful.
6. Can I charge the battery with solar power?
Absolutely. With a MPPT solar charge controller Your LiFePO4 battery can be efficiently charged via solar power – ideal for long tours or off-grid camping.
