Kind of pointless going beyond 3c IMO. You get diminishing returns in terms of time saving and he final balancing cycle of the charge will usually take a minute or two so. I can't say I've ever needed a lipo charged faster than 20 mins anyway.
Great info, thanks Ryan !! So, if the storage voltage is, let say, 3.8v(30% of total battery capacity), then this 70% that required to make it full helps us to calculate approximate total capacity of our battery, (how true it is😅) and, with time, when the battery is "old". What's the voltage of 0% battery capacity? (Voltage, from where to start the charging to check the actual capacity?) Thanks a lot!!
Really appreciate this information. For anyone else using these: Zeee and GensAce at 1C. Reedy batteries at 2C. Spektrum Gen 1 at 3C (the ones with the balance lead). I went and looked through all of my batteries, and two of my favorite Amazon-available manufacturer's had nothing on the labels, but the instruction manuals state that we should not exceed 1C for charging (Zeee and GensAce). Reedy and Spektrum's older batteries also lack a charge rating on the label, gotta read the fine print.
Eh, unless I leave batteries sitting around fully charged and ready you go (which I don’t), I’m going to have to plan ahead when doing my charging anyway. Lately, I’ve dropped my rates to more like 0.5C, as it only takes 20-25 min more and the charger’s actually able to put a little more milliamperes into the battery. Plan ahead, get a tiny performance and run time boost.
Good info on charging. What about putting the Lipo into storage mode? My Venom pro duo only allows a 1A storage rate ... so no choice there. However my other charger I can set the storage amp rate. After a day of running, some Lipo's might not have been used and are at full charge. Can you still storage (or discharge) at 1C/2C rates ... or is that a different situation?
sorry, a bit confused ... and obviously I'm missing something. When charging, you say "charge at 1C or 2C" ... what exactly is that? I use 6000mah 2S batteries (racing 1/10 scale buggies). So, does 2C mean 12A and 1C mean 6A charge rate?
Excellent idea and explanation. People are always horrified when I tell them my charging rates. Saying they always charge at 1c at the lowest possible. Lack of understanding.
That's a really good explanation. 1C charging can also be dangerous for batteries with physically damaged cells. Damaged cells may never reach 4.20V and other batteries connected in parallel will exceed 4.20V. The reason this happens is that most 1-cell batteries are connected in parallel with two batteries. In other words, if you open a 4-cell battery, there are eight sheets. No matter how good a charger is used, it is difficult to prevent overcharging because only the average value of the two batteries can be known. Charge as slowly as time allows and make sure to check the battery temperature.
All lipos that use parralel cells are marked that way to differentiate them. A 2s1p pack always has 2 cells and a 2s2p pack has 4. So saying that it's most of the time that case is completely wrong. Most packs are sold as 1p packs and not 2p packs as you stated. I for example stay clear of parallel packs as you can never say in which condition the cells are as they are always shown as 1 cell on the charger or lipo tester. Also there is no average value for voltage on parralel packs. They are always exactly the same.
I'm glad you mentioned packs getting hotter running vs charging. The only time I worried about any lipo was after pushing them in the field, not sitting on a charger. I have several chargers, and still use my Duratrax dual charger. After many years, I have only had one pack light off, and it wasn't on any good charger. It was a small 2S pack that only fit its included charger! Glad I still pay attention, or it could have went south quickly 😁✌️

Agree!

I did a voltage vs capacity video on the channel. It includes a graph.
Good advice Ryan, thanks. Personally, I always balance charge my batteries. Don't know if it makes all that much difference, but I do it anyway.
Every charge complete is a balance charge.

Yes I can and think I showed this in the video. If not it was in another cut that got edited out.

You are correct on your charge rate examples
Hi. I see store as "NORMAL". What is other possibility selectable please?
Normal and quick are the selectable storage modes.
Excellent idea and explanation. People are always horrified when I tell them my charging rates. Saying they always charge at 1c at the lowest possible. Lack of understanding.
Yes!
Cool info as always 👌! So far this $25 3yo Haisito HB6 Smart Balance Charger has been great if just need the basics
Perfect, that sounds good!

You forgot that when you charge lipos in parallel all lipos voltages equalize at the same level

Wow so far, I've not had a single pack let go on me. Fingers crossed though.
Just charge your lipos at home, while you sleep and don't worry about how long it takes.
