What amp should I charge my 4S LiPo?

If you use a 4S pack, the motors will draw more current, since the props will spin faster. In this case, the motors may be drawing 20A each, so you now need 80A – so a 4S battery rated at 65C of 1.3 capacity would still be fine.

At what amp should I charge my 4S?

The general rule of thumb is to take the capacity of the battery in mah and divide by 100 to get a conservative estimate of what you can safely charge at. So 850mah/100 would give you 0.85A charge rate, 1A should be plenty safe.

How many amps should I charge my LiPo battery?

For the vast majority of LiPos, the Charge Rate is 1C. The equation works the same way as the previous discharge rating, where 1000mAh = 1A. So, for a 3000mAh battery, we would want to charge at 3A, for a 5000mAh LiPo, we should set the charger at 5A, and for a 4500mAh pack, 4.5A is the correct charge rate.

What voltage should I store my 4S LiPo?

If left fully charged, the cells in a LiPo will unbalance quickly. Proper storage voltage for a LiPo is 3.85V per cell.

What is a fully charged 4S LiPo?

LiPo 4S batteries consist of 4 LiPo cells connected in series, hence the "4S" as part of their labels. Each cell features a nominal voltage of 3.6-3.7 volts (mostly 3.7 volts), a maximum charging voltage of ~4.2 volts, and a cutoff voltage around 3.2 volts.

How many amps do you charge a LiPo battery at?

When should I land my 4S battery?

You should land when you have used 90% of your battery capacity! At this point the battery should theoretically be at around 3.5V – 3.6V. You should not however, rely solely on “mAh consumed”. The data from a current sensor resets to zero when the power is disconnected, or when the FC restarts.

How long does a 4s LiPo take to charge?

That charge rate would take 1 hour and 40 minutes just to replace the 5000mah, but, will take slightly longer as the charge rate slows at the end, and the cells are balanced. Assuming it's a good pack, 1 hour and 50-55 minute would be a good estimate.

How long can you leave LiPo fully charged?

Never leave your LiPo batteries sitting around on a full charge for more than 2-3 days. If by the 3rd day you realize you are not going to use your battery today, you need to discharge your battery down to 3.6v-3.8v per cell for safe storage until you are ready to use the battery again. 11.

How many amps should I charge my 5000mah LiPo?

5000 can charge at 5 Amps. basically the mah/1000 is the charging current.

How do you calculate amps for LiPo?

For example, if you have a 1300 mah capacity battery and it is rated for 30 C continuous, then the maximum continuous current is 1.3 * 30 = 39 Amps. The same battery might have a 40 C burst rating, meaning the battery can safely output 1.3 * 40 = 52 Amps for short periods of time.

Can I charge LiPo at 2C?

Basically yes, they do. I have seen very little from actual manufacturers saying that their Lipos are safe to 2C. Safe to 2C, btw, means minimal impact on longevity. You could charge many lipos at that but their cycles would be much lower.

How long does a 4s LiPo battery last?

LiPo batteries don't have expiration dates, but they can see a drop in performance after excessive use or passed time. to 18 months,” said Sarah Petrova, a hardware engineer at Intel.

Should I discharge LiPo battery before charging?

LiPo batteries also don't develop memory or voltage depression characteristics like NiCd/NiHm batteries, and do not need to be discharged before being charged. But they're not without their downside. Mishandling of these batteries can lead to fire, explosions and toxic smoke inhalation.

Do LiPo batteries lose charge when not in use?

So based on my experience, they don't lose much of a charge over time. Lipos have a very low self discharge rate when compared to nimh and nicads. There are established storage procedures that are believed to prolong the life of these types of batteries. All new lipos are shipped at a storage voltage of approx.

How often should you balance charge a LiPo?

I've always kept a close eye on which packs are always in check. But my 1/8 buggy I balance them every time a charge, because one cell in all my packs always seems to pull one cell lower then the rest. A good battery should be able to hold a good balance between cells for a month without a problem.

What is the lowest safe voltage for LiPo?

The usable voltage range for a standard lipo battery cell is 3.2v to 4.2v. Any lower than 3.2v and the battery may be permanently damaged. Any higher than 4.2v and you significantly increase the risk of a battery bursting into flames.

At what voltage should I stop flying?

DO NOT fly this battery again. 6S LiPo batteries should charge up to 25.2V, and should be considered fully depleted (not damaged, just normally used and ready to recharge) at approximately 21-22V. Any lower than that and you begin to risk damage. And the loaded voltage is always going to be lower.

How many amps is 2C charge rate?

A 2C charge rate would be 10A, a 3C charge rate would be 15A and a 5C charge rate would be 25A. You should now be confident when it comes to setting the “AMP” rate when charging LiPo batteries.

What voltage should I set my LiPo alarm at?

What voltage settings are considered safe for maintaining a lipo battery. I have seen recommended alarm ranges from 3.7v per cell down to 3.2v per cell for lipo's.

How do you keep LiPo batteries healthy?

What to do if a LiPo catches fire?

Lithium-metal battery fires can be put out with a Class D fire extinguisher. Larger battery fires are best handled with a foam extinguisher, CO2, ABC dry chemical, powder graphite, copper powder or sodium carbonate.

Can you overcharge lithium batteries?

In a lithium-ion battery, overcharging can create unstable conditions inside the battery, increase pressure, and cause thermal runaway. Lithium-ion battery packs are required to have a protection circuit to prevent excessive pressure build-up and cut off the flow of ions when the temperature is too high.

What is 4c charge rate?

The claimed charge rate of 4 C corresponds therefore to a current of 12 A, or roughly to 0.12 A/cm^2, above the expected diffusional limiting current.
