TECH TIP: COLD WEATHER AND LIPO BATTERIES

Cold temperatures and LiPo batteries don't mix well.

The temperature of a LiPo battery has a direct impact on its discharge rating. Performance will begin to decline when the battery's temperature falls below 50° F (10° C); serious problems arise when the battery falls below 20° F (-7° C). The C rating and consequent performance loss increase with battery temperature. Because the battery voltage will drop under load due to more excellent resistance, degraded discharge ratings will shorten run time, lower top speed, and lower total power. This stresses the battery, which will shorten its lifespan and performance. Additionally, it will put more strain on the capacitors in the ESC, which may cause damage. The batteries will experience similar stress and have a shorter lifespan if they are charged while cold.

Using batteries with a higher C rating can help a little, but even in that case, you should keep them as warm as possible. You don't want to let the batteries start out cold since they will stay warm while you're using the car and drawing power from them. Lower temperatures will reduce your C rating by half. EEK!

What can you do then? Make sure your LiPos are ready before going for a run. Before using them, keep the batteries at a comfortable temperature using hand warmers, rice heaters, or your own body heat. Additionally, avoid charging your LiPos when they are cold, as this may cause stress and cell damage. Our final and priciest recommendation is to relocate to a warmer location.

That's it! By adhering to these cold weather guidelines, you can ensure your electrical system continues operating at its best!

Start with a pack that is fully charged.

Whenever possible, make sure your batteries are at least 50° F (10° C) heated before using them.

Use your body heat or wrap your batteries in a LiPo battery warming bag, rice heater, or hand warmer. Any heating devices should be handled carefully to avoid overheating and possibly damaging LiPo.

In colder climates, use batteries with a higher C rating.
