SkyRC NC2500 Pro: How to use Step Charge function

[@tonypapagna3744]

Delta peak is considered the “drop back voltage” when charging ~ if the battery fluctuations more then the setting ~ 1-8 ~ the charger will stop charging ~ set it 1 and it will stop right away ~ set it 8 and it will keep pushing current Set it to 1 and this will save you battery ~ set to 8 and this will cook your battery

Can you explain what is delta peak from skyrc 2500pro ? And what the function for battery ? Why if use 8 delta peak will cook the battery

[@yusrydeluna]

Delta peak, also known as ΔV or delta-V, is a feature in smart chargers that helps determine when a battery is fully charged. Here's how it works: - *Voltage monitoring*: The charger observes the battery's voltage levels as it charges. - *Voltage drop detection*: The charger detects when the battery's voltage begins to decrease, indicating that it is fully charged. - *Charge termination*: The charger then stops charging the battery, preventing overcharging. This feature is especially useful for nickel-cadmium (Ni-Cd) and nickel-metal hydride (NiMH) batteries, which experience a voltage increase during charging until they are fully charged. Once they are fully charged, the voltage decreases. A delta peak charger can detect this decrease in voltage and stop charging the battery, preventing overcharging and prolonging the battery's lifespan. - TL;DR: Set a low delta peak will terminate the charge when detect a voltage drop early, set a bigger delta will continue to charge until it hits that delta (which is almost never) hence will contribute to overcharging.

@@yusrydeluna so, what ideal number for delta peak on skyrc nc 2500 pro if I need to cut the voltage in 1.55 volt ?

[@yusrydeluna]

This charger is unlike nc2600 where u can hard set the cut off voltage. This charger uses the delta peak to determine when to stop. So if you want it to stop as soon as possible, set to 1. If you want it to stop as late as possible, set to 8.

Thank you for all you do~ save me a lot of headache ~*lolz*

[@oddycool]

Thank you brother

I don’t Understand. Entering in step 2, 100mah of charge, however the voltage of the batteries drops, from the maximum peak ... from 1.57 it drops quickly to 1.50 ... 1.49 ....1.48 .... Etc. What is the point of the step charge?

[@yusrydeluna]

1) Unfortunately there's no magic in the batteries voltage. It supposed to supply 1.2v. The 1.5v we see will decay quickly. On average the batteries start at around 1.45-1.48v only (at full peak). 2) Step charge is to program the charge rate after it has "charged" a certain capacity. E.g. first 100mah charged with 1000ma. Then next 100mah charge at 1500ma. Then finally charge at 2000ma. You may employ this strategy to an empty battery e.g. charge 2000ma until 800mah then change to 500ma for next 200mah (total charging up to 1000mah) then change to 200ma until the charger auto stop. Whether its useful to you or not depends on your expectations.

current too high

[@yusrydeluna]

if you're racing, even rechargables are "disposable". if you're using it for other purposes, I guess it's not healthy. Hence I have to agree. Use with caution.

[@SinnerManGaming]

@@yusrydeluna nope. I am racing and using the same batteries for 5 years now. no matter how smart the charger is, if the user is not smart enough batteries will be disposable.

[@yusrydeluna]

Sure man. You do you. I think my batteries were still with me since day 1 (almost 8 years already), and if the batteries sucks, I'd throw them away without even salvaging. There are extreme users who subjects their batteries to high current just to get a slightly more boost advantage but thats about it. How long do they last I have no idea because i am not that extreme.

[@SinnerManGaming]

@@yusrydeluna 2500mA charging 😂

[@yusrydeluna]

I tried man. I tried my best to spoil my batteries. I really do. But modern chargers are so smart they actually prevent you from doing that. I have not really come across anyone, at least in my community, who complained about a bad battery due to high current charging. The worst that usually happens is their battery sleeving got so torned up it became naked. But apart from that, to really try to damage ni-mh, using modern smart chargers? Its going to take a while.
