using properties of water is the closest way to describe electricity to someone is unfamiliar with how it behaves thank you for your taking the time to teach those who choose to listen
This really helps, thank you. You should really make one specifically for Ebike users. That’s why I am here. I notice that when I do a heavy draw down for let us say a hill climb, The battery percentage will drop heavily, let’s say to 60%. Then if I stop and let battery rest, The battery percentage climbs back up over 80%. I see a fair amount of comments where E bike users are confused by this.
Until you said about the ads I hadn't noticed why I was watching, but with no ads I had no reason to click out. I may have not explained that right but Thanks for no ads and sharing your knowledge.
I think I get what you're saying. I want to make a little revenue (to loop 100% right back into the channel) but I do not want to annoy my viewers. I hope you enjoyed the video and thanks for watching! Glad to see you got that heater pack out of service. 😀
@@diyrenewableenergyelectron4996 Since I am not monetized can you explain do they pay for minutes /hours of video watched or do they pay for minutes / hours of ads watched and can you tell if people watch your ads.
I just got monetized so I'm still trying to figure that out also lol. I think they pay for time watched on the ads as opposed to time watched on the video. If I start making more sense of the analytics I'll let you know!
I appreciate your simple explanations. I ride and EUC (electric unicycle) which can draw a lot of amps to stay balanced at speed. Understanding voltage sag can keep me from falling on my face! If I were to make a suggestion it would be to include a caption of each lithium batteries you are testing. I believe you compared Lead Acid, Lithium NMC, and Lithium Iron Phosphate (LiFePO4). (When you're not familiar with them they all sound alike).
Thanks Good explanation, I was using makita batteries for an ebike and they don’t drop much, I built a battery myself and even though bigger ah it hits the lvc quicker if using high throttle, but will go further on low power. I’ve been trying to understand why and now I see the voltage just sags to death, I used good Samsung cells but they have a low amp rate.
You got it! Typically the cost of high amperage delivery from a cell (like the makita batteries) is a lower capacity. They won’t have much voltage sag but don’t have as much runtime. Cool to see it in action though, isn’t it? Thanks for watching!
I’m thinking my BMS went bad. Every time I get close to absorption, two of the eight batteries change charge rates. One goes up and the other one goes down while the other 6 stay in unison. Then when I do A draw by the inverter, they magically go back to balance? Then when they go back to absorption they diverge again. 🙈
@@diyrenewableenergyelectron4996 Yes I verified the voltages with a multimeter. I have eight Battle Born Batteries wired in series/parallel 24 V. The six worked perfectly for about six months, then I added two more and right from the get go they were about 30 V divergence between them when they arrived. In the past I had always had them one volt difference if at all. So I connected the two to the six others and did not draw a charge for 24 hours. Right from the start they had issues. Two of them kept diverging from the others. I called Battle Born Batteries and got two different answers on what the battery capacity should be. I thought it was 800 amp hours for eight batteries. I had also sent an email, and got a different answer of 400 amp hours. After calling again I got the official word that 24 V on 8 12v 100 amp hour batteries would be 400 amp hours. I thought that fixed the problem until they go in into absorption. This is when they go out of kilter. I start to draw power off the batteries and they go back into synchronicity. So the two new batteries have some kind of BMS problem? 🤔
Hmmm. If it is the two new batteries giving you problems I would try documenting it as well as you can in video and seeing if Battleborn will warranty them. It does sounds like there's something weird going on. If you have 5 parallel strings of 2 12V batteries in series, they physically cannot be different voltages unless the BMS is disconnecting . Do you have a clamp meter to measure current? I would be curious to see if there is huge amperage movements occurring when the two start getting weird. When they start to equalize again at some point later in the day (when you draw power like you said) I wonder what kind of current flows when they synchronize? How large does the voltage difference get before they synchronize back up? You could have a large amount of current flowing when that happens. Something is definitely off about that though.
@@diyrenewableenergyelectron4996 The eight batteries are wired in series/parallel. Four on top and four on the bottom. Connected together in four connections negative to positive. Then the top line in positive parallel and the bottom line in negative parallel. Never had a problem with six batteries. I’ll have to do more testing. Right out of the box these had issues. It’s only been three days. I hope by having these connected they don’t start a fire? Six of the batteries were at 14.39 V and one of the problem batteries was at 15.30 V and the other was at 13.47 V. Quite a divergence from the other six. Thanks for your input, I still have a lot to learn.
Derp. No idea why I said 5 parallel strings..... I blame Project Overkill lol. If they had problems right out of the box I would 100% get with battleborn. That battery at 15.3V is concerning..... I don't think there will be a fire, but permanent damage of the offending battery is possible. I don't know what voltage the BMS in the Battleborns cut off charging at but that 15.3V battery is allowing your cells inside to charge to at LEAST 3.83V per cell. No bueno. 3.65V per cell should be the max for LiFePO4 cells. If it were me I would remove the offending batteries from the other 6 and investigate the two individually. It is possible it is only the high voltage battery that is causing issues. Hold on, I read carefully how you said you have these batteries wired together. The bottom terminals of the bottom row is paralleled together and is your main negative. Are the positive terminals on the lower batteries paralleled together? Likewise with the negatives of the top row. Not your main 24V connection points, but the terminals where your series connections are. Are there any parallel connections there? This whole thing could be a connection issue. If you don't have the terminals I mentioned above paralleled together then you can get these voltage differences because you aren't parallel connecting each 12V battery to its 3 counterparts from the other strings. If that didn't make sense let me know and I will email you a picture or something :) I wish I could be more help! Edit: the connection thing is a shot in the dark but worth mentioning.
Excellent demonstration, very well explained too!
Thank you!
