Trolling Motor recycled 80ah 18650 battery pack

This T245 Trolling Motor battery was built for my older brothers fishing kayak. It's in a 30P4S configuration with 80ah of usable storage.
After a car landed on his head (not kidding) the easiest way for him to get around is in a wheelchair take a look at his channel at some of his projects he has entertained himself with over the years.

Cut the mix on the background music please. Even after you lowered the volume I had a hard time separating out your voice. Question: Has anyone come up with a system for generating bar code stickers for cells that could be used to quickly identify a cell and relate it to a database?

[@HBPowerwall]

Sorry you didn't like the music really put effort into that part of the video too :( I think many have talked about it but not really come up with a way to truly get it to work

[@Markle2k]

It's not simply a matter of taste. It's the fact that I can't hear what you are saying. Choosing music that avoids the frequencies in the speech range would help too. Surely there must be copyright-safe music that has been created to complement voiceovers.

[@HBPowerwall]

I’m sure there is and I’ll take advice onboard

[@HBPowerwall]

Just tried it on my kids computers and can hear fine - definitely need to look into it more

[@Chickey]

I have to admit on my setup the music seemed really loud but the parts where you were speaking were the correct volume.

[@fmpApps]

I was considering building my own battery but after watching a few of these videos I realize how little I know about doing it and would better spend my time earning the money to buy one. I do respect those who have learned these skills.

[@alasdair4161]

That will give amazing run times. I just did a similar pack, after making my own outboard using a 2hp mariner leg I fitted with a 90v brushed motor (750w) so I wired my pack as 10p20S with some higher voltage mosfet's in my own PWM speed controller. After a whole weekend of use, it still only reaches ~3.4v/cell. Your build is way better than any lead acid options. He could also plug a lipo alarm into the balance port when in use, it will fire off when there's about 20% remaining with liion's..

[@HBPowerwall]

My bro is a massive TECH head and will no doubt improve it :)

[@issanesheiwat1396]

How is this better than any lead acid option? Why couldn’t he have just used an 80ah lead acid marine battery? I’m only asking because I’d like to learn more about building a battery pack.

[@ClaudioHenrique-gy9cx]

I think because acid batterys can't discharge much than the li pack can. Sorry if im not correct and the bad english :) (but acid battery can suply more ah in a shurtly time, for this are used for start the engine of cars)

[@rahulpathania78]

Awesome. Just one advice, never cut the BMS wires, rather flatten up the bunch and tape it in the end. Cutting BMS wires alters the resistance hence, the resistivity in each group of cell while balancing during the charge process.. something not big, but not too small to be ignored. Thanks 👍

[@HBPowerwall]

Good tip!

[@storminite2041]

I really like how you easily explained how one battery can mess the whole system up if does not workcorrectly. Thanks for bringing it to my attention. I didn't understand fully what was involved. Thanks

Are you positive?

[@TomTheDutchy]

The thing that surprises me is the amount of time spent on sorting the cells to an exact capacity using some simple software to calculate which cell goes in which pack. Given the uncertainty on the measurement of your capacity the actual number is not very important, if you round them all up or down to multiples of 50 or 100 you are fine as well and it saves you a lot of time.

[@HBPowerwall]

That idea is common with several thousand cell packs - smaller ones repackr works very well charge and discharge voltage is max of 0.02v

[@dgb5820]

MANY many hours Alan I assure you :) but definitely a rewarding result! Thanks for tuning in

[@harleypater7317]

1. Given up on fusing for low current (per cell) applications? 2. Cheap balance boards are more trouble then they are worth!! Balance charge or use a balance checker and only charge to 4.05v once your happy the cells are well matched, checking occasionally. 3. 4s is the new 3s Most camping items will run no problems at 16v and run down to 10v. 4. Where did you get the Asus batteries from at a good price? Stored at 3.6 to 3.8v those batteries will outlast time itself.

[@HBPowerwall]

Tried to fuse but looked ugly - yes that's my excuse ugly lol but took every step possible to still build a safe battery. Still needs load fuses and waterproof box for it but that'll be in the next video. I agree those BMS cause more issues than they solve but I was TRYING to build this battery as good as possible. 4s is definitely becoming more popular Over time i've saved 100's of laptop battery packs with these cells in them - too good for powerwall use I thought.

[@freetrailer4poor]

I wonder if this battery will outperform a 100ahr deep cycle lead acid battery in regards to on the water use and duration?

[@HBPowerwall]

1/4 the weight and I dare say heaps more stored energy that's safe to use than a Deep Cycle - 100ah is really 50ah that is safely useable to have longevity of you're battery

[@freetrailer4poor]

I have been on the water on over 100 (maybe 300) trips in a boat with a trolling motor and one 100ahr lead acid battery. Many times when you run it down to empty, you can tell the motor is almost empty the way it behaves. You probably have to monitor the voltage of Lithium to make sure if you are at the end of the lake, you have enough to make it back, or have a small dedicated backup battery. I was just wondering due the inefficiency of the lead acid how the run time would compare if the motor was run on high with a 100ahr lead acid compared to the runtime on the 80ahr battery until the motor basically stopped. Life expectancy does not matter if you have to row. I was actually in the process of building one before this video. The trolling motor I still use is 40 years old MX60 Minnekota.

[@fookutube501]

And that 4.08 cell though he was doing well.RIP lone ranger

[@hoginfog]

Why do you wait for 30 days fo self discharge instead of measuring cells' internal resistance?

[@HBPowerwall]

[@Away907]

I've made 25s4p pack for the trolling motor using new 3400mah batteries from aliexpress. Also decide not to take risk with built-in BMS and use ISDT charger instead - at least i can get numbers this way. Gave it a try recently. Running on the slowest speed(3kmh) it lasted for 6hrs and 15min, consuming 180w on average. Wattmeter indicated i managed to pull almost 1150whr up to the moment when voltage dropped to 3v/cell. Going faster require about 300-400w and resulted in low voltage warning when battery was less than 25% of capacity. BTW, these motors can take 16.8V, no need for pwm controller. This will kind of push it to the limits. My motor is rated 430w at 12v, according to wattmeter it was pulling 600w+ on 16.8v battery. Running it full throttle reduces the range. I was getting 15km on medium speed and 18km on low speed. Max speed will empty battery in 1.5hrs with about 9-10 miles covered.

How much money would the battery cost if you bought the cells new ?

[@HBPowerwall]

NCR18650 cells go for about 5 bucks each in Australia x 120 plus labor & warranty - $800ish?

[@matthiasbretonnier4015]

How do you gent this amont of cell 🤔🤔

[@HBPowerwall]

In the early days it was weeks and weeks on the phone full time calling 100's of people a day was some hard work but definitely worth the effort

[@gazsope]

It is said that the storing voltage of liion batteries should be around 3.7-3.9V but not fully charged.

[@HBPowerwall]

I believe that to be true

[@nadiushkabr]

Hi, Can You tell me what the settings of spot welder are?

[@HBPowerwall]

out of the box, max on the dial and 8 on the pressy buttons but that changes if you use the 110v version - mine is the 220v version and seems to be 10x better

3S or 4S if use for UPS ?

[@HBPowerwall]

Thats a good question - what UPS are you using and are you planing on using the grid to charge it... if that's the case both are bad choices for lithium-ion cells as the voltages for both are very wrong. Fire will follow quickly.

So no need a bms? Icharger is enough to charge them cells?

[@HBPowerwall]

I bought the wrong bms it has a 50amp unit now. But only for over/under charge protection really balancing is done by the charger each time.

Don't you love the short work a Spot welder makes of a huge battery pack!!!

[@HBPowerwall]

There is just a few min of cutting up nickel then bam it's done! And looks so dam good lol

[@njfulwider5]

I started out only using a Spot welder(or my homemade built spot welders), I am just now getting used to soldering a cell. If I could get away with it, I use a spot welder on everything. Love the work you put in on this. That battery should last a long time!!! Good cells you used also. You Can't beat those NCRs

[@HBPowerwall]

Next challenge will be keeping it dry and servicable

[@haroldking979]

I assume its been in service for a while now? Any word how long it lasted etc? Keep up the good work :)

Haven’t tuned it in since too cold lol haven’t even done a load test

[@DoulgasSherk]

Hello excuse ignorance but what does the colors of battery cells mean that they are from the same code?

the color of the cells just identifies them you can see more here - secondlifestorage.com/celldatabase.php

Trolling motor output will only will increase trolling power once you up your trolling game, otherwise you'll never reach the trolling immortal

[@abdullaalmosalami]

No BMS in the end with this large pack?

[@HBPowerwall]

A good BMS will cut off at low or high voltage to prevent damage. Also balance the battery. I use a hobby charger to charge so every time It charges it balances. I can live with it over discharging.

[@abdullaalmosalami]

@@HBPowerwall I see OK. Thanks for responding! I'm still new to building batteries so useful to note.

How you do that bud? I'm in the process of doing a video to test the capicity of a tesla battery

[@swfurn2]

Very nice build. Thank you! Be cool to compare the size and weight of that battery to what you would need for a lead acid of the same capacity.

[@HBPowerwall]

For sure - i'll see what my brother currenty has when i go down to install and test (might have to wait till it warms up a bit)

[@swfurn2]

Thanks!

[@recharge4708]

they have qr codes to do a data base thing, how much would you charge for a battery?

All manual - i don't sell i'm sorry

[@jamesturner2126]

Is this whole process needed if we start with brand new unused cells?

[@HBPowerwall]

Pretty much but you wouldn't need to capacity test the cells or use the secondlifestorage.com/repackr.php repackr tool to build a balanced pack.

[@Fpvcrewgr]

I have a electric scooter battery 36v how can I charge out of the scooter? I'm using it for something else. Can I just connect the scooter charger directly to the battery ? Thank you !!!

[@thedave7760]

Should be ok as long as you keep the charge controller and all it's wires in place. If you start changing things you could be in for a shock or a fire. be careful.

[@PainStreakGamingYtAJtojbbros]

how many hours to charge this

[@HBPowerwall]

about 10 hours @ 10 amps

[@GarryL277]

Have you tried using your pip4048 inverter to run your grid tie system off grid which in turn will charge your butteries when the solar load if more than the house ?

[@HBPowerwall]

No, that would end very badly - Its just a bad idea - connecting any 240v to the output of the pip will instantly require a new mainboard - know a few people installing their pips and getting the input and output mixed up. Best to get the right inverter for the job from the beginning

[@GarryL277]

Have a look at evtv video he has done it with 5 grid tie inverters with a cheap Chinese inverter and tesla batteries at 48 v

[@HBPowerwall]

Ooh I've seen it done but from what I've seen there are many pitfalls - cheap inverter works differently than the PIP's

[@joshanpigeons4701]

Sir thanx but it is not opening

[@huskypup3489]

I think you may want to include a current limiting device on each cell since you have so many in parallel. If one cell develops an internal short, the other 39 cells will happily discharge into the bad cell and create a burn hazard. I've seen others use a thin piece of wire in series with each cell for current limiting.

[@HBPowerwall]

That is how i have all my packs built - this one was meant for a boat on the deck so if there was an issue it could go for a swim :P

[@elk3909]

if you have quality cells that current would burn up the positive tab inside the cell as this is a safety feature
