Innledning
In ice fishing, power isn’t optional—it stay essential. Devices like fish finders, LED lights, heated pads, or underwater cameras all needs steady energy. If anglers don’t manage their batteries right, especially during freezing weather, they risks complete power failure while out to the ice.
Here, we explain the five most common mistakes ice anglers often make with they battery, especially when using a 12V 100Ah LiFePO4 Battery, and how to avoid those errors for more safe, reliable trips.

Mistake 1: Exposing the Battery Directly to Freezing Temperatures
Why it’s a problem:
When temperature go below freezing (0°C / 32°F), lithium batteries loses performance fast. Cold causes voltage sag, and charging while the battery is frozen may damage it’s cells permanent. Many anglers don’t even notice until their unit shuts down halfway through trip.
What to do instead:
- Put the battery in insulated box or wrap it by thermal material.
- Keep it off from the ice floor and protect it against cold wind.
- Choose batteries with BMS which can stop charging when temperature get too low.
One trick—put a small hand warmer into the battery box. It might help getting few more hours in cold.
Mistake 2: Using the Wrong Charger or Charging at the Wrong Time
Why it’s a problem:
Some users plug they lithium batteries into lead-acid charger, thinking it’s fine. This mismatch causes either overcharging or system shutdown because the BMS cut it off. Also, charging in cold (below 0°C) can create lithium plating, which can’t be reversed later.
What to do instead:
- Only use smart charger made for LiFePO₄ and has correct charge profile.
- Charge indoors or in some warmer spot before going onto the ice.
- If battery feel cold, don’t plug to it right away—let it warm up first.
Mistake 3: Draining the Battery Too Deep
Why it’s a problem:
Anglers sometimes think they can run the battery all way to 0%, but doing that cause stress on it cells. Even though LiFePO₄ performs better than SLA, complete draining still hurt battery lifespan.
What to do instead:
- Keep SLA battery above 50%, and LiFePO₄ around 10–20% SOC.
- Monitor battery with volt meter or other smart display to see live power draw.
- Remember: a 100Ah LiFePO₄ will give you around 80–90Ah usable energy—if managed right.
Mistake 4: Powering Too Many Devices Without Planning Load
Why it’s a problem:
Even small stuff like sonar, glove heaters, and phone charger add up over time. Especially when you use them all together with inverter, battery can drain fast—6+ amps is very possible.
What to do instead:
- Make list of all your devices, and note how much amps they use.
- Try this formula: Runtime (hours) = Battery Ah ÷ Total Current (A)
- Shut off any non-essential items—mostly those making heat or using AC.
- Add labels on the cables if you not sure what each thing consumes.
Common Ice Fishing Device Power Draw Table
| Enhet | Avg. Power (W) | Current at 12V (A) | Merknader |
|---|
| Fish Finder (Lowrance) | 5–15 W | 0.4–1.2 A | Depends at screen brightness |
| LED Shelter Lights | 10 W | 0.8 A | Low draw for all night |
| Heated Gloves | 20 W (pair) | 1.7 A | Used only sometimes |
| Telefonlader | 10 W | 0.8 A | Depends on phone and type cable |
| Portable Fridge | 45 W avg | 3.8 A | Surge up around 6 A |
| Sonar + Underwater Cam | 20–30 W | 1.7–2.5 A | Combo units use more than expected |
| 200W Inverter (Idle) | ~10 W | ~0.8 A | Even idle, still pull current |
| 200W Inverter (Load) | ~150 W | ~12.5 A | Power loss around 15–20% via AC |
Running things like heated blankets or electric kettles by inverter will drain 100Ah battery in less than 2–3 hours.
Mistake 5: Not Storing Your Battery Correctly Between Trips
Why it’s a problem:
Some people just leave their battery totally empty or store it at freezing garage. Over time, that causes battery swelling, less capacity, or might not charge again at all.
What to do instead:
- Keep battery between 50–80% charge if you won’t use for a week or more.
- Store in dry indoor area with temperature from 10 to 25°C.
- If not used during off-season, top off once every 8–10 weeks.
Bonus Tips for Ice Fishing with a 12V 100Ah LiFePO₄ Battery
- Use fuse or breaker on the wiring—it protect against short circuit.
- Pick Anderson plugs or waterproof terminals—they better when you wear gloves.
- Carry small 10–20Ah backup battery just in case for light gear or emergency.
Konklusjon
Managing your 12V 100Ah LiFePO₄ battery the right way makes your ice fishing trips much safer and long lasting. You don’t need do anything complex—just avoid these five mistakes. Keep the battery warm, charge at proper time, and always plan how much gear you run.
