Very nice thank you.❤❤

Will the total deplete faster mixing Ah ? Scooter batteries I have 2x12v20ah and 2 other 12v with one 7.5ah and one 12ah Would this be ok to run in parallel for 48v

Will this work with a Kayaks2fish Nextgen 11 that has a copy of the Mirage drive?

I am not an electrician but a financial guy. My one friend is an electrician but he is not an expert on batteries. I understand this concept of paralleling different capacity batteries as I am doing it for years. He falls back on his book knowledge and say it can't be done and after a lot of discussion he still say I am wrong and it will damage the batteries.

Your water analogy is incorrect. The water pressure at the bottom of each tank will be exactly the same. Therefore the flow rate will be the same from each tank. If l measure the water pressure at 100 meters in the ocean and l measure the water pressure in a 100 meter 1 meter diameter tube the water pressure will be the same. And the ocean has a lot water in than the pipe. Batteries do the same .

I have been trying to figure out how much current each battery would contribute to the 6A required. I've tried figuring by the Ah ratio of each battery compared to the total Ah of the batteries connected together. So 17.5 Ah + 7 Ah = 24.5 Ah. With a 6A load the batteries would last 4.08 Ah. Things fall apart after this. I tried to figure out how much each battery is giving. I divided 17.5 Ah / 24.5 Ah = 71% for the first battery and I got 29% for the second battery. How do you figure out how much current would be drawn from each battery? Also, this is assuming a linear relationship. I am interested in this because I am playing with solar panels and golf cart batteries. With one test, powering an inverter @ 12V 50A the solar panels were supplying 20A and the batteries were supplying 30A. I don't know how to figure this out with the math. What determines how much current comes from the batteries and how much current comes from the solar panels? Thanks in advance for any comments or ideas.

Took me three years to find your information... everybody else I consulted was just wrong!

where can i order this?

Whats a safe voltage difference between 2 battery packs before connecting in parallel?

That’s far and considering you’re pretty close to the sea level, it’s even better 💪

Best idea mate! Maybe this Saturday after kayaking I’ll get my 50ah to camping just in case 🤣

I love your system and I can’t wait to try it this Saturday! Hopefully 50ah it’s enough for a 24lbs motor.

Use tiny leads will be evaporated and protect battery. Other put diodes before junction so current can go ONLY OUT OF BATTERY BUT NOT INTO BATTERY.

Crimping is less prone to wire breakage from vibration and flexing. Soldering like that can spoil the connector surface if your terminals are not sealed. Lastly, the terminals are not designed for such small wires, which is why you're having so much difficulty assembling them..

Can i parrel 2 same volt batteries but have diffrent Max continuous discharge current: 20A and 30A

The problem with paralleling batteries it that they never are at exactly the same voltage. There are always equalising currents flowing between them. And the bigger the gap in internal resistance - the bigger such a current will be, no to mention that the external currents will divide not exactly as you have planed

I wouldn't say wires act like fuses I've burnt stuff or fried batteries but the wires were perfectly fine. People might miss your point and literally think that the wires will burn before something worse happens. Caution.

Parallel lead acid batteries can help charge one that won't accept a charge due to high internal resistance...or i think even a capacitor in parallel can do the same

Thanks bro

I like the bending over wire to crimp, but not a fan of your soldering technique and exposed wire (too mount on the stripping). Cheers

Sir can i make 12v battery by using 3.7v different capacity of batteries means All are 3.7v batteries but 1200+1200+2000=4400mah ,3.7v 1200+1200+2000=4400mah,3.7v 1200+1200+2000=4400mah,3.7v Like this total 9cells One set contains 3cells=4400(1200+1200+2000) So 3sets = 11.1v 4400mah Can I make it ? Is it safe

I love ur explanation Just one question when u say the batterie should be at the same voltage you mean full charge ? With the condition of knowing that the specs of the batteries are for example 48v 21ah and 48v 13ah I should know my both batteries are at 48 v when they are fully charged yes ? And 0 v when they are fully spent i hope i got this right 😅

Are you intentionally ignoring internal resistance or do you just feel it is not enough of a concern to bring into this discussion?

🤝

Could you tell me how you connect 50ah battery to distribution hub. Thank you

Great brother 🤠

Hey on my one battery i have2 +s and 2 -s wire going in to each controller but my second battery only has 1+ and 1 -. Can I get away with just hooking it up to only 1+ & negative on the first battery

Just a note if you are connecting the PWM to the 50ah battery to your motor: My battery came pre-wired with the connectors as did the PWM so all that was left was to connect the motor to the PWM. Following this tutorial I connected the "red-to-red" which turned out to be the opposite of what I needed. Thankfully the PWM (or the battery, can't remember which) came with two connectors so I was able to cut and re-wire.

I about shit myself at 12:50 when I heard the baby. Sounded just like it was downstairs in my home!

While I understand you want the batteries at the same voltage when connecting ... if you need to ... is there a way to protect the battery/limit the current (in particular with lifepo4 or would the BMS control this for you?)

How would I hook this up if I’m running your battery to a Yak-Power circuit switching system?

This really is a super cool product!

I love this power distribution unit. However, it would be nice to be able to get additional pigtails and extension cables for a reasonable price. 17.00 for a 1.5meter cable is expensive. I think that is a serious hurtle to this unit being able to grab the universal de-facto kayak wiring standard. Lastly, we really need a through hull mounting system for these plugs if you can get those manufactured it would be a slam dunk. I like these connectors way more than the cheap, SAE connectors, for sure. Thanks this is a super cool product looking forward to future innovations too!

For charging a small and a big battery could u bridge it one terminal on positive of one battery and one terminal of other battery on negative? Or is it recommended to charge seperate

Awesome. Do you guys sell that other white led light? I see the green one on your site but not the single white one.

It does not work that way. A battery is an electro-chemical device. Ohm's law applies only electrically. Battery internal resistance is dynamic, it changes under load, Ohm's law follows the chemistry, not the other way round. The video presumes chemistry ill follow Ohm's law. It will not!!! A test would not be very difficult, or expensive, to perform. New batteries will differ minimally, as they age, it will be statistically impossible for two such batteries to follow Ohm's law as claimed in the video.

Hey guys just wanted to ask if you can let me know how much this full package is please?🙏

How would you ensure the voltages are the same? Its very unlikely they would be so they would rapidly self discharge. Clearly you never actually tried this for real.

sir can you explain about wire gauge for those parallel need. my problem is when we gain out put with higher A level what wire gauge should use..? i am new to this electric side so kindly can you do a video thank you.

7Ah battery will provide 1.71A and 17.5Ah battery will provide 4.28A

Thank you 👍

If i have both 60v but different 25ah the other is 70ah is fine?

Tt

Are you certain this is accurate with Li-on/LiFePO4, because they have *flat voltage curves*. Your premise is that due to the significant drop of voltage with SLA/AGM/GEL batteries -- the batteries will discharge proportionately based upon their capacity, which is correct. *However,* when you have batteries whose voltage does not go down for the bulk of their discharge (as with LFP) then this premise wouldn't hold true.

What about series?

Thanks! Great explanation.

Your video shows a male connector from the distribution hub but sold as female connector which means you need additional hardware to connect to FPV battery. Why do that?

what's the power of this pump liters/hour? thank you

Wow thank you! I understand now .. cause I was planning to get an extender pack for my e scooter but at a lower capacity so I was worried of burning my other battery if I connect them in parallel.. anyway thank you this video was a big help.

Oº.ºOps... know what you are saying; go learn practical stuff before talking»»»» a 24 volt and a 12 volt batteries in parallel *IS NO ff EXAMPLE** They WILL eat each other, E X P L O D E Choose better examples edit at 04:00 you say it
