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.

[@jackrodgersjr]

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)

[@drubradley8821]

Doing my yearly check-in, to see how things are going... with the 18650's reclamation standard you have created world wide... still running strong, I see, and am glad to see.

[@HBPowerwall]

[@AlanMedina314]

Great Video, love the wire management and spot-welding. Thanks for sharing.

[@HBPowerwall]

Thank you Alan!!

[@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.

[@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!

[@Wicked03GT]

Man I wish I had the means to build this myself. Very satisfying to watch it come together. I would buy this if you sold them, exactly what I need for my kayak trolling motor

[@anangrysack]

I learned alot from your powerwall videos and made my own 12v 80ah battery for my trolling motor, having not seen many for that purpose and now here you are! I actually just made up my second for a 24v system. I dont even know what they really are rated at, each 12v battery is 150 1.65ah 18650... I got about 20 running hours using it in different variations between charges to 4.10 to 3.5. Got a bit to finish up and we will see how all 300 handle the new 24v 80lb Terrova

[@anangrysack]

I also fused all mine with 7amp wire, learned the hard way that they actually work! Very tedious pen soldering

[@mwbgaming28]

great to know where i can get those exact cells from just recently built a battery box with an inverter and lighter outlet out of random cells i had laying around (it was a nightmare to match the capacities of each parallel set by tacking lipo cells onto each cell pack to balance the capacities) capacity: 750wh 240V power: 500W 12V power: 240W 24V power: direct connection all enclosed in a steel box with holes cut for all the plugs and indicators thinking of building a DIY powerwall for my caravan next

Ditch the music, your voice isn't annoying as you think. Music intro/outro is all you need otherwise Really good.

[@jitendraparit9374]

I am using 11s10p configuration for my BMS project. That means I'm using 11 stacks in series with each stack consisting of 10 cells in parallel. I am in a dilemma if must balance each cell in the pack(individual cell balancing- 2 wires coming out each cell) separately or get a wire out of each stack(2 wires coming out of each stack consisting 10 cells in parallel) to implement passive balancing algorithm, SOC, SOH. Can you give an insight on which one is more preferable?

[@DubiousEngineering]

Good work, I like the idea of using the imax as a balanced charge system... I’m going to employ that on my mobility scooter upgrade! .... great tip!

[@slv8507]

12V motor does not burn from 16.8V? I want for the motor Minn Kota Endura 55.

[@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

[@korishan]

Since this is the latest video, I'll ask here. With your spot welder, are the tips spring loaded? If so, do you push them down until the spring bottoms out? I saw another video where they said spot welding is a resistive welding. Pressing too hard actually reduces the amount of resistance and it doesn't weld as good. Maybe you can play around with pressure on the tips to get different results. Perhaps this is why the arm on the device would work better as it was spring loaded, too.

[@HBPowerwall]

yes they are spring loaded - found if I played with settings I didn't need to really press down so hard the springs compressed. Found if it sparked I was doing it wrong

[@HBPowerwall]

I love the results - pitty I couldn't work out how to do cells fuses & make them look sexy as well

[@ahaveland]

I think Tesla cells use a plate with holes that are bigger than the positive terminal and line up with them, then a short fuse connects them. With nickel strips on the positive side, you could make a grid that lies *between* the cells and spot weld the fuses to it, or even try a copper plate with large drilled holes. The negative side can be spot welded as normal. Best place to attach the power cables is at the centre of each terminal plate, or at multiple places for really high currents. With the power cables at the corners, the entire 30P current goes through just 2 strips worth of nickel!

[@PolakeXD]

Hi,I was building a solar system for my garage and wanted to buid my DIY power wall.Now I have a problem with my BMS and need some help since until now I only made 8s 4p battery packs.The problem is that when I charge my pack then the small balance charging wires (8pin balance charge connector) which has a 0.11 mm² core.My question is now if it would be safe to replace the existing balance connector wires with 1mm² core wire for each pin or should I go with 0.50 mm² core wire?

30 cells x 4 in parallel - 4.2v so effectively it's 12v min 16.8v max charge in the thumbnail that shows positive & negative joined on the left and again on the right - on the other side the gap in the middle is bridged join all cells together.. God I hope that explained it enough.

[@Jopoiato]

Hi, very nice video. How long after you charge each cell separately, you measure the voltage to make sure they were all fine?

[@HBPowerwall]

would have been weeks if not months of resting it's a very good test to do when using old cells

[@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.

[@ZoomZoom870atGmail]

[@MrSnapy1]

Sweet pack! neater than mine I went the fuse wire route. l have ran into a few problems with my 4s packs the high voltage pushes more amps into the motor reducing the AH rating. Tried a few buck convertors to keep a steady 12.5v but they get HOT will try a few more beefier ones or add a tiny pc fan. Before my buck burnt out I was getting 20% or more run time @12.5 vs 14-16 volts. The bright side is it supercharges the trolling motor lol Still it beats a 3s pack which the motor falls flat with much capacity remaining. Just remember to monitor voltage a 4s will easily drop cells below 3 volts if not monitored.

[@HBPowerwall]

Next one I build will be fused between the Series packs I think. It's the neatest way I can think of setting it up. Will take out the whole battery but better than nothing. Hope I can make it to the gold coast soon to my brother's house to test it out. But I'm about as good at 'water' as I am at 'mathing'

I was just relooking over this older video, about what size is the spotwelds? My spotwelder welds two spots about 1.5mm in dia. The 4ga, cables and weld tips and holders get so hot after about 50 welds I can't hold it anymore, it has two layers of of shrinktubing, one is the TEMco 1" dual wall stuff, with glue, and it has paper wrapped around shimming the tuning from 1/2" to just over 3/4", it feels hot enough to melt the glue! I'm thinking my tips are not sharp enough, and the welds are too big. I also was welding the thick nickle, and the batteries are capable of well over 400amps, I have about 20" of 4gauge cable going to it, with 12" of 2ga, going to the relay, it works well down to 9.5v, being 3s lipo, that's where I stop! Any suggestions? Maybe I should take it a bit slower?

BMS is also protects against under voltage to save the cells. That said this battery still gets used quite a lot and i only use a balance charger - does work well if you accept it's dangers

[@ronaldbizlink1311]

Kinda new to this thing so would like your kind advice as I am also doing it for a trolling motor but my target will be bout 200pcs of 18650s. And what is your view on fusing the batteries as opposed to not fusing them?

[@HBPowerwall]

Well Ebikes don't fuse, its a smaller battery, you're on water if it has an issue over it goes lol

[@twcstransam]

Neat project Pete

[@HBPowerwall]

TY Sir ... 10x longer to film and edit than to just make but I love the end result, can't wait to test it on the water

[@twcstransam]

The PCM was a good idea. I'm sure it'll be good, curious as to how long it will last you.

[@twcstransam]

Is that a battery powered glue gun?

[@brettwatty101]

Nice work. I got a 24v Trolling Motor with a 7S 20P pack arout 50aH.

[@HBPowerwall]

Would love to next do a 24v one have to see if my bro needs to upgrade his motor lol

[@lsgt5132]

Just what I'm looking for. Been searching forever. How did it work out and how much run time are you getting?

[@thenima]

Enjoyed the video .

[@HBPowerwall]

Thank-You thenima - really enjoyed making this one - pitty i screwed up the audio .. but live an learn

[@billtrue3017]

Yes we are hear to learn not to danse ,but its great what your doing thank you and happy new year

[@HBPowerwall]

thanks bill, HNY to you also

[@orlatris96]

Quantos Volts tem essa bateria? E quantos amperes? Carrega e faz balanceamento com esse imex B6? Um abraço obrigado

[@Munky332]

Are you buying the laptop batteries yourself and then recycling them? or do you have someone you just order the batteries? I'd love to get a huge ~200ah 12v battery (sectioned off into either 4x50ah or 2x100ah sections)

[@jamest.5001]

Also I used the batt hookup, nickel fuse, 100 cells, in a square, with added strip, in a square, 2cells from the edge, with two strips crossing about 3cells between, with another nickel strip across the top. I have a 12g, silicone wire, connected to the double strip areas and another at the very top. For 4 total, since you tested the fuses. I'm curious if you think this will suffice? My system can only pull about 300 amps. And this is one of 3+ banks, so 100 amps peak, it's not perfect, but I have the current coming from 4 locations in the middle of the pack. Not many have videoed actual use of this stuff. Any idea? Thanks

[@amigoselvador2786]

just looked at how you work i really Enjoy it.. I came out with a better and useful result by the way I was not bothered by the music, not because I did not like it. just i am 70% deaf..Some want to hear everything to understand properly.Some do not hear anything but understand everything Dear Sir HBPowerwall Thank you again for giving a chance to someone like me to understand and left from here with something useful

[@HBPowerwall]

glad it worked for you :) I enjoyed editing this one

[@HBPowerwall]

@@biancad6289 I hope you recover soon lol

[@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

[@GarryL277]

HBPowerwall kzbin.info/www/bejne/gJaaYqeYopx_jbM have look

[@DIYkanalas]

Amazing job. Virtuoso video production. Like.

[@HBPowerwall]

thank-you

[@DIYkanalas]

Hello. I have little project, you can watch and appreciate my job. Look to my channal - kzbin.info/door/IZk32bpkaEzrCWvBb9z0nQ?view_as=subscriber

[@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!

[@novagiaaditasembiringmelia5086]

That's a very nice video sir but how can you measure the Ah of each battery cell?

[@HBPowerwall]

i use an www.diypowerwalls.com/opus charge discharger unit.. works well. After the pack was build i used an www.diypowerwalls.com/X6 to check the capacity of the whole pack 78ah total useable storage in it .. not the quoted 80ah lol

[@johnboyle7984]

What run time would you expect from this setup? Also how long would it take to charge this up?

[@HBPowerwall]

Not sure as unloaded at max speed it's only 1.2amp draw - bet that changes once a load is added. As for charing it depends on your charger. Bigger chargers would have no issue doing it in 10 hours - my charger will probably take 20-30 hours flat to full

[@alphacube6052]

Hi Pete, now you've used the spot welder but fuse are no longer fitted/required for this pack?

[@HBPowerwall]

Really should have put more effort into adding fuses of some sort - for its application (in a boat) if there is an issue it'll just go overboard. It will also be moved and bumped a lot much like an ebike battery. I've gone out of my way to make sure I'm using the best most balanced cells I have laying around. Time will tell if it was a good or bad call.

[@milvolts1]

Hello, I was wondering if you could give me your suggestion. I have 6 packs of 24-18650 cells in parallel. And I want to build a power bank that can power 12 volt Accessories I also have a 12v 1000 watt pure sine wave inverter. How can I connect all 6 packs together to achieve the 12 volts. Thanks so much for your input.

[@stefanbr4mke]

mario sellet 12 Volts us a little bit tricky. 3 packs in a row results in 10.8 volts (3.6×3) ..at full charge it is 3x4.2=12.6 which would suit to the inverter. Battery state 25% would be around 3,3 volts per cell (under load) ..so it would be 3x3.3=9,9 volts. Typical low voltage cutoff is at 10.5 to 11 volts. That means you can only use around 70%, perhaps 60% of your battery. 4 cells in row would be over 16 volts full charged and cause shutdown or even damage to your inverter. My favorite would be 7Serial but you need an 24v inverter.

[@masonharrelson]

How long does it take to do a full charge on the Imax B6? I'm building a similar battery 4s20p and was planning on initially balance charging it off my B6 but I'm wondering if theres a faster/ more simple charging method I could use. Thoughts? Great vid. I enjoyed the music. Mastering everything with an Auratone speaker could help the mix a lot. Cheers.

[@HBPowerwall]

Haven't had a chance to discharge the battery yet, got very cold here so haven't even done the testing of it yet unfortunately. I have two more videos planned on loads and charging .. shouldn't be a few weeks. Day Job pays more than youtube so have to juggle my time

[@Jsak666]

Is there a video for your brothers variable speed controller, I would like to make one myself

[@HBPowerwall]

the link in the description to the eBay item, I've never built something like that

[@aaronag7876]

HI, could you do a video for something similar to this video but for vanlifers to replace their 110ah battery and for it to be changed via a MPPT controller ? Thanks

[@HBPowerwall]

I should start doing some smaller builds with high levels of detail.. ill look into it in my spare time

[@sshutupurface8345]

do you charge the cells in parralell and if so how many at a time what voltage and amps

[@the3rddecline]

Pete, how much self discharge do you consider okay? Do you check each cells voltage before you store them for 30 days and check again? Some of my BT-C3100 chargers state that a cell is full at everything between 4.15 and 4.20. So I just now sort them by voltage, let them sit and check them again.. but I am unsure what self discharge is okay, if any at all over 30 days.

[@HBPowerwall]

30 days less than 0.05 of a volt give or take

[@GabeLynx]

Is not the fully charge voltage too high for 12V? I'm starting the same project for a trolling motor of 12V. im finding it hard to find out if the 16.8V will be damaging the device in the end.

[@HBPowerwall]

That is the reason for the little black box it's a PWM controller so you can adjust the power

[@marinizo1]

why was not the 4,8v cell? I saw you had cells with 1.5v

[@deathincarnatesplace]

also if you use an rc or ebike motor at 6 volts and then turn a stator on a stand you (generac 120/ 10 magnet at 2 rotations per second) you get a really long battery life you just need an ac throttle and an ac ebike motor. also a controller for the first motor must be built to keep it from rotating to fast.

[@Sardonic1981]

will those nickel spot welding bars be ok for high drain applications? 300A? Also, what spot welder do you recommend?

[@HBPowerwall]

Not a chance of 300amps - I like the goo.gl/UBjZLA Sunkko Unit

[@886luke]

What is the program you used for capacity optimization and cell placement? It looks interesting.

[@raisagorbachov]

I'm working on a Lion battery for my motorhome. Only 10-15AH but that's plenty for what I need. So far, 5 x 4 lithium battery holders, 20 protected 18650s. I'll run 5 packs in parallel of 4 in series giving me 13.8v nominal. That should allow me a peak draw of at least 6a.

[@dunukic]

Do I need to consider battery cell resistance when building a battery pack out of different recycled old laptop li ion cells?

[@HBPowerwall]

You should consider and factor that could cause issues.

[@mertcapkin7263]

I have the same Imax charger. Is it correct that the charger basically replaces the BMS while charging but that you don't have anything that protects the battery pack when being used?

[@HBPowerwall]

Just common sense & the knowledge that if it over discharges i'll have to replace it :}{
