When it’s chilly within the winter, your LiPo batteries endure — you’ll see extra voltage sag, much less punch, and noticeably shorter flight occasions. The chemistry inside merely doesn’t carry out effectively when temperature drops. The answer? Heat your packs earlier than flying. iFlight simply launched a heated battery case designed precisely for that objective, making it simpler to maintain your batteries within the optimum temperature. After testing, I can see why this would possibly turn out to be a helpful winter accent for some FPV pilots.

What Is the iFlight Heated Battery Case For?
This isn’t only a case — it’s a purpose-built heating resolution for LiPo packs. Chilly LiPos don’t simply lose flight time — in addition they sag tougher beneath load, making your quad really feel sluggish. The perfect working temperature for LiPos is round 30°C–35°C, and this case can deliver your packs as much as that vary earlier than you are taking off.
Construct and Design
From the skin, it appears to be like like an ordinary zippered equipment case. Inside, nevertheless, is a black plastic temperature management module constructed into the lid.
The management unit contains a show and three buttons for menu navigation and altering settings. The display can show the present temperature, goal temperature, enter voltage, and cutoff voltage.
On the underside of the management unit, there’s a plug that appears like a steadiness connector, it gives energy to the heating parts.
Inside, there’s a mesh pocket for smaller equipment.
The case presents beneficiant storage, able to becoming 20 6S 1000mAh LiPo batteries. The interior area is roughly 29x20x10cm
Powering the Case
You’ll be able to energy the heated case in two methods:
- XT60 Enter (7.4V – 30V) — Works with 2S–6S LiPo or Li-ion packs.
- USB-C PD Enter (positioned on the precise)— Works with a PD-capable energy financial institution or wall adapter (100W Really helpful).
Further USB Energy Output
The left-side USB port is a 30W energy output — helpful for charging your telephone and GoPro. It’s additionally helpful for dumping charged LiPo power into your gadgets on the finish of a session so no power is wasted.
How It Works
Since there’s no handbook within the field, I’ll attempt to clarify find out how to function it. Word that this isn’t the official instruction, simply my private expertise how I take advantage of it.
Turning On/Off
Maintain the center button for two seconds, then maintain once more when prompted.
To energy down, repeat the identical course of.
Setting Cutoff Voltage
On the house display (the place you see 2 bins), use + or – to set cutoff voltage.
Necessary: When the enter voltage drops beneath the cutoff voltage, the heated case will beep, nevertheless it doesn’t cease heating, so you could unplug battery manually to forestall over-discharge.
Coming into Work Mode
On the house display (with 2 bins), press the center button to enter work mode (with 4 bins).
In case you keep on the house display (two bins), it powers down after a number of seconds.
Disabling Cutoff Voltage Alarm
Press + and – collectively to mute quickly.
Setting Goal Temperature
Maintain center and – buttons for two seconds, then alter with + or –. It’s in Celsius by the way in which.
Efficiency Testing
Voltage Accuracy
The enter voltage studying appears to be barely under-reported. For instance, when my battery was at 25.0V, the case displayed 24.7V. At 20.5V, the case learn 20.3V. This small discrepancy isn’t an enormous challenge for my part — it simply means you would possibly get a low-voltage warning a bit early. Nonetheless, it could be good if the voltage may very well be calibrated or made extra correct from the manufacturing unit.
Energy and Present Draw
When the case is heating:
- 6S battery enter: 2.23A at 25V (~55.75W)
- USB-C enter: as much as 55W (20V, 2.75A)
A totally charged 6S 1000mAh pack might present round 20 minutes of steady heating, however in real-world use (with a reasonable temperature setting), the heater cycles on and off as soon as the goal temperature is reached. In winter (say 0°C), with the goal set to 30–35°C, a 6S 1000mAh pack ought to simply final over an hour.
Temperature Accuracy
Temperature readings are fairly correct. In comparison with my thermometer:
- Thermometer: 26°C → Case: 27°C
- Thermometer: 43°C → Case: 44°C
Word that the temperature sensor is positioned contained in the management unit (black field), so temperature management relies on that time’s studying.
How Quick Does It Warmth Up?
With the goal temperature set to 60°C, I measured the temperature each 5 minutes. The thermometer was positioned in the course of the case (not touching something) and linked to an exterior monitor so I might report readings with out opening the case and shedding warmth.
- Begin: 26°C
- 5 min: 37°C
- 10 min: 47°C
- 15 min: 50°C
- 20 min: 50°C
The heating price is spectacular — an 11°C enhance within the first 5 minutes and one other 10°C over the subsequent 5 minutes. Heating from 0°C to 30°C would probably take solely about quarter-hour at this price.
Nonetheless, the temperature plateaued at 50°C as a substitute of reaching the 60°C goal. That is probably as a result of the temp sensor is positioned within the management unit which already hit 60°C (presumably as a result of additional warmth from the voltage regulator), inflicting it to prematurely cease powering the heating parts, though the air temperature contained in the case was solely 50°C.
This isn’t a deal-breaker for me, as I wouldn’t warmth LiPos to 60°C anyway for security causes.
Freezer Check – Temperature Holding Capability
It’s presently summer season right here with room temperatures round 26°C, so to simulate winter circumstances, I examined the case in my freezer at roughly -10°C. I set the goal temperature to 35°C and left the case inside for 20 minutes.
After 20 minutes, my thermometer confirmed the interior temperature holding regular at 31°C, which is sort of good given the intense chilly.
Limitations
No product is ideal. Listed below are a number of minor drawbacks:
- Expensive for what it’s
- Doesn’t routinely cease discharging when voltage drops beneath the cutoff voltage
- No directions included
- Enter voltage can’t be calibrated and reads barely low (not an enormous deal)
- Temperature unit in Celsius (°C) solely
Conclusion
Not gonna lie — at $59.99, the worth for this easy heated iFlight battery case feels a bit steep. You would most likely construct one thing comparable for much less. Moreover, for a lot of pilots, it’s not a necessary accent (I’ve personally been flying for a decade with no battery heating case). That mentioned, if you happen to’re severe about efficiency — particularly in chilly climate — this case is a superb comfort merchandise that works proper out of the field. It retains your batteries heat and at optimum situation throughout your flight session.
Get the iFlight Heated Battery Case from these distributors:
It’s additionally extra versatile than it appears to be like. Along with storing and heating batteries, it may perform as a battery discharger, letting you safely deliver down the cost of totally charged LiPos you determine to not fly. Simply bear in mind: it received’t cease discharging routinely when it reaches the cutoff voltage. It might beep to warn you, however it is going to proceed to empty your battery till it’s utterly lifeless. You should manually unplug the battery when the alarm goes off — so it’s essential to solely use this case if you find yourself round.
