Hey. Hope your well. Looking at doing a 4x 105ah build the same as yours. But I’m struggling to find out which bms to use? I only want to use this for usb connections and maybe a 12v socket. Like you help me please. Kind regards.

[@KathyQin]

Hi there, I am Kathy. I am reaching out to express my admiration to your professional knowledge in battery DIY.

[@naterpotater76]

I love this. And I think the fact that you didn't double the size just to have an AC inverter built-in is genius.

[@Jasonoid]

Most of my setup runs directly off 12volts. For example my 12v ICECO fridges, fans, camping shower, led lights, flashlights all just need 12v. This power station provides TONS of power to run any of those items! I do have a inverter but I really never use it. Thanks for watching!

[@k5jrx3]

Same. Ive built a couple of these, only with SLA batteries, and use 12v equipment. My HAM Radio room runs almost exclusively off of 12v. LED lights, fans etc are all 12v. That also helps to keep RFI down. As of right now I have a computer that is running AC, but I will set an inverter up soon. Fun projects though.

[@jeffe.9904]

Jasonoid, there are a lot of "Ammo Box" videos on KZbin and I have watched them all 😂 , However, Your video is second to none! Your voice instruction & detail and your overall build quality is Superb. Thank You for making the video. I believe you just gave this wannabe DIY'er the confidence to attempt my first build 😳 . Thanks again.

[@Jasonoid]

Thanks for your comment! I love this battery box! Still working great! I'd recommend building it, prices on 80ah cells have dropped quite a bit since this video came out!

[@chipmeister111]

Thanks for putting this together, it came out nice. I really appreciated the last segment where you showed up close what it looked like on the inside. I'm gonna put something like this together for a trolling motor for my small boat. Thanx again.

One day too late! I just ordered two Lion Safari UT 1300 , 12V 105Ah Lithium Iron Phosphate (LiFePO4) Batteries. They have a nice BMS so I think I can still build this box without the BMS. I have ordered the ICECO VL45. I'm looking to power it. I may add a battery monitor. Great video you do a great job showing how you build and you explain things well.

[@Jasonoid]

Thanks for watching! Sounds like an awesome project! Let me know how it goes!

[@livingcoramdeo]

@@Jasonoid Thanks! When you charge your batteries, where do you connect the charger?

[@Jasonoid]

@@livingcoramdeo I will make an adapter for my Anderson PP panel to make charging easier, but for now I connect alligator clips to the negative BMS lug and positive terminal. It works just fine....just have to remove electrical tape before hooking up the negative.

[@InLawsAttic]

We bought a spare huge car battery for an across US trip in case needed it. Now I would like to turn it into a battery box to use. I wish there was a DYI kit with all the parts together to buy. I like the set up you use. Thank you for the tutorials. Love the review on the EB70, plan to buy one soon. Bookmarked your website.

[@Jasonoid]

I have a much more simple battery coming out soon, just waiting on some parts. Make sure to check back in a month or two for that battery build. 100AH LiFePO4 DIY battery for under $400....that's my goal!

[@k5jrx3]

Awesome video we had a big storm on Thursday I just got power back today.4nights with no power do have a gen but for fridge only. Don't want to be left like this again.

[@Jasonoid]

Have you seen the 'all in one' power station units that have a battery, inverter and charge controller built into one unit? Pretty awesome tech coming out these days: kzbin.info/www/bejne/a3q6p55qfZ55Y6c

[@hayzersolar]

We had a big storm move in the area Thursday June 29th about three-thirty in the afternoon. Power was restored on July 3rd about 4 in the afternoon. On June 30th I went to Amazon and got the blue yeti EB 3A. Not knowing anything about this stuff looks like I picked a good power unit. So I subscribed to your channel and try to watch every video to understand the whole solar generation. I live in Indiana so we have pretty good sun here. Without watching any videos I also ordered a 12-volt refrigerator. So thanks for the videos

[@Jasonoid]

Awesome build, sounds like you will be using it for some fun stuff!

[@w2ark2uvc]

I would like to give you the following suggestion when wiring the power pole connectors as you have done. You do not want to mount the connectors as you have done because you can accidentally plug your connectors into the middle connections and destroy what ever you have plugged in. Either make the connectors black/ red/ red/black or red/black/ black/ red. I assembled my anderson power pole connectors in a battery pack as you have done and accidentally plugged into the two center connectors, thereby reversing polarity and destroyed my ic-706 radio. Other than that suggestion, love the way you constructed your battery pack. De W2AR, Phil Mollica

[@Jasonoid]

I agree, I have it on my to do list to flip over half the pairs. Thanks!

[@derykmacleod4979]

Great Video! I ordered 200 amp cells from a vendor that Will Prowse recommended. All together was about $750 but more power then my little transit connect can use even when I add a 12volt fridge lol. Thanks for sharing this, I shared it with 2 groups that constantly talk about those over priced jackery units. Mine is going to be the leisure battery fro my van wired to a fusebox and renogy dc to dc charger (and eventually a 100 watt portable solar battery for when I am camping and using the battery.) I added a manual switch for the wire coming from my alternator so it won't be always sending juice back to the battery since I want to keep it around 90% as being full and try not to drain it below 10% either so I might get more cycles out of it. I can check the battery gauge and when it needs to be charged, charge it when it is nearly 90%, turn the switch off so the battery won't cook.

[@Jasonoid]

Appreciate it, thanks for the share! Your project sounds awesome, I bet it will work well for you!

[@posteroonie]

If I read the Alibaba page for the BMS Bluetooth adapter correctly, the user can set the over voltage and under voltage parameters. I'm with you, I want long battery life, so I would get extra capacity and set it to range from 90-10%. The great thing about the larger cells is that at 1C they can push a lot of amps so they wouldn't heat up at 100a when using an induction cooker.

[@Jasonoid]

@@posteroonie The BMS is completely customizable. Pretty awesome. You can set the exactly when you want the cells to stop charging and discharging. Love it! I just ran a fridge in FREEZER mode for 48 hours on this battery. My last battery wouldn't even last 24 hours without charging it

[@posteroonie]

BMS's top balance, meaning that they don't start to balance until the cell voltages are over a certain level, nearly fully charged. So it might be a good idea to run your batteries up to 100% every couple of months to trigger the balancing. The balance voltage is configurable for the BMS in the video, so I would set it to just below 90% if my overvoltage limit was at 90%.

[@theshepard22]

Im loving the instruction and slow pacing as a novice lifepo4 builder. My first question is- what purpose does the voltage display serve? What voltage is monitored? Is it just the outlets that are on its left and right? Im interested in doing something VERY similar. 304ah eve battery, same bms with blue tooth. I'm also planning to add insulation around the entire box, add heating pads to the sides and a couple of computer fans as well. Those will have their own thermal sensors with parameters that tell them when to turn on and off, and adding life to the battery by allowing it to be in more moderate temps more often. The fan will bring in air from the vehicle and expel it through a vent. A few things im not sure of are- is it more crucial to keep it cool or to make sure its warm while using the electricity from it? Does the bms turn off the solar input? And if so, when does it do this? What should be prioritized with safety and build quality with these things?

[@Teknopottu]

Hi. Old comment but hey, he missed it. Voltage meter is for battery voltage, same voltage that the 12V plug and USB-charger uses. It is important to keep batteries and other electronics cool enough but cold can harm sometimes. Charging batteries when they are frozen can damage them, some battery systems have in built low temp cut off and even warmer to use some of the power to keep them from freezing. I believe some BMS's have low temp cut offs. Moisture can be be bad too, keep this in mind when designing projects. Making holes for plugs on the side of the box is usually better than on the top in case of rain. BMS turns off charging when the voltage is right, don't remember the LiFePo4 spesifications right now. Too high voltage should not be able to input. I'll left prioritizing for the maker. If the battery box is not meant to be thrown in the back of your car and not to spend a days and nights in damp conditions and scorching sunshine, then it is okay to make it not so durable.

The prices have dropped quite a bit since my video, 100ah are priced as low as $175!! The larger cells might not work in the case I used in the video but all the principles are the same, just find a larger case to use.

Very cool build!! I have built a few similar boxes using 18650s and small plastic HF ammo boxes. I never thought of this larger box for a 100 Ah trolling motor power cell I built. I have the same bms which comes from Battery Hookup for about $85, fyi. I also use a usb with volt meter built in to save a little space. How are you securing the cells inside the case so they don't jump around in case it gets turned upside down? Thanks for the demonstration, it is very innovative. You have inspired me to add some cigarette plugs and a couple of LED back up lights for after dark. Thanks

Very thorough and informative build Jason! Thx for sharing. Was wondering if you had ever thought of using Li-Ion before choosing to use Li-Po instead before the build? Am trying to choose either to use these both for my build as well. So thought of getting your thoughts on it first. Li-ions are cheaper but has lower capacity on each battery, Li-pos are much more pricy but has higher capacity on it. But which one lasts longer in the long run?

[@Jasonoid]

Lifepo4 have 2500 cycles at least per cell if treated correctly, lithium Ion only have 500. Lithium ion are a fire risk, especially for a diy project. I would stick with lifepo4, they are slightly heavier, but are very safe! Check out the SOK 100ah batteries, they are very good quality but they have the built in BMS already that has the low temp cutoff. For complete diy aliexpress has many cells to choose from, you just chose the middle ground pricing on cells, I avoided the dirt cheap ones and the most expensive ones.

[@pain_weaver]

To help keeping from damaging the batteries when hooking them up it's a good idea to have a discharger. Empty battery is safer to work with 👍

[@Jasonoid]

The cells weren't fully charged when I connected them but I could have discharged them more. Appreciate the tip! Thanks for watching!

[@FourInTehMorning]

Please review recommended cell orientation for your cells. Most prismatic cells have to be orientated vertically not horizontally, otherwise it will damage cells over time. Cylindrical cells can be mounted horizontally.

[@Jasonoid]

Correct, I don't push these cells at high loads so they shouldn't have an issue leaking, just pull 10 amps or so running small gadgets and 12v fridges. I built a new 100ah version using cylindrical cells, put the video put yesterday, it's a better build.

[@Jasonoid]

[@mischamick]

I'm not an expert for LiFePo4 batteries, but connecting the cells directly in parallel would damage at least a LiIon or LiPo battery (if not destroy them) if the charge state of the individual cells differs too much. Usually, you should check the cells voltage and bring them to the same level if necessary before connecting the cells together in order to prevent to high current flows between the cells. Is this different for these cells or is it simply a mistake on your part?

[@Jasonoid]

They were very similarly charged, just was a final step to balance them together.

[@12floit33]

Great build! Mine are very similar all though my cabling is not as neat 😄. Have you thought of putting a solar charger in there to be able to hook up a panel? I've done so in both my setups and it works great in summer trips ^^

[@Jasonoid]

This one I could probably fit a very small mppt charge controller in the case. I have since built a new 100ah battery that's a little better / easier to assemble than this one. It uses batteryhookup 100ah modules. You can view it here: kzbin.info/www/bejne/q3-UmWOOftWZisk

Thanks a lot for this video. As I am building my version 2 solar generator hence watching a tons of videos related this and undoubtedly this one can be said one of the best video I have watched. Indeed, I have already watched this video couple of times due to few instruction/parts list. I have one question though related to the Anderson connectors. In this build, it looks like you have mounted a 4 port Anderson plug flush mount whereas your all other connectors look like those are mini-Anderson plug type. May be this is a naive question but does the mini Anderson power-pole connectors fit in the regular Anderson port ? In fact I am purchasing the connectors but cant be sure how those are compatible.

[@Jasonoid]

The Anderson power pole connections, the plugs and ports, are all the 30amp size.

Enjoying the video and how to information. One comment, with the volume up enough to hear you well the music played during the assembly section is notably louder causing me have to turn it down. Common complaint of mine with about 99% of youtube content makers, never have figured out why that is so common. A lower volume for the music section than the content voice over would be highly preferable to this viewer.

Curious as to how much "gadget" recharging could be done from one full charge. Could see using it to run a small 12v fan to circulate heat in a tent for example.

Was looking into making something like this for my car audio system currently I have 3 Xs power 3400 batteries...They all weigh quite a bit and weigh down the back of the car. I would need something I can draw quite a few amps from at once.. I'm pushing like 9000 W RMS

[@Jasonoid]

Weighs like 25 lbs, usually they can handle 1c discharge rate, so 80 ah is 80 amps.

[@Pinkielover]

@@Jasonoid Nice and light but I don't think it would be able to handle it.. system is Drawing too many amps ..

Hi Jason great video,how do you charge the battery , what size ,type of charger do you need. Thanks Mike

[@Jasonoid]

Hey Mike, make sure you check out my newer 100ah build as well. It's better than this one: kzbin.info/www/bejne/q3-UmWOOftWZisk As for your questions... I use a couple different dedicated lifepo4 chargers. My solar mppt / DC to DC charger is the Kisae DTM1250. Excellent dual input charger. My ac charger is a circuit specialists 15v 60amp charger. You can find it on their website. I use the positive and negative connections from the Anderson powerpole connections to charge.

It might be easier to manage if you just built a 36v battery. There are BMS systems designed for 36v. Check out those videos on the youtubes

You can charge it via the Anderson power pole connections as long as you have a MPPT designed for lithium batteries. The fuse holders can be found on amazon, get at least 8 to 10 gauge holders

[@Jasonoid]

I connect my lifepo4 battery charger to the Anderson power pole connections on the front of the battery box. Those directly connect to the positive and negative terminals of the battery (fused of course). The BMS is installed in line of the negative terminal. Does that make sense?

[@ozne_2358]

Great video. I've been on the suggested BMS page and I have a couple of questions: 1) How do you choose the BMS according to the amps drawn ? For example, I plan to use the battery for a trolling motor that draws 34 A max. So the 60 A BMS should be ok, right ? 2) I noticed that you used a circuit breaker. However, on the BMS page, on the app screenshot, it seems to show (scroll down) an "Hardware short protection" and "Hardware overcurrent protection". Wouldn't these make the circuit breaker redundant ? And what's the difference between them ? I guess the circuit breaker is there just in case.... Thanks.

[@Jasonoid]

Thanks for watching. You'll be good with the 60amp BMS, you can always go higher for future projects if you think youll get a bigger motor. I used the circuit breaker style switch in order to power down all ports and front controls. It just a benefit it also works as a circuit breaker.

[@kimmer6]

Ozne_ Yesterday I got my 200 amp hour lithium battery with integral BMS and no plastic case. I replaced a similar 100AH unit. This is for a modified Minn Kota trolling motor battery box that has a factory 60 amp circuit breaker on the terminals. The box is used to power up medical equipment where there is no AC power and trees block sunlight to solar panels. But it would probably work very well to run a 35 amp trolling motor for a long time. Did you build it?

Lifepo4 has a higher voltage than lead acid so no regulation needed. Voltage ranges from an average of 13.3v to 12v at the lowest point.

@@Jasonoid Have you sourced a reasonable DC-DC charger? I'm not sure how boxes like Jackery are getting all this stuff in there! Charge controller, inverter, DC-DC-charger. AND the batteries! How do they do that??? One of my primary uses will be to run a DC refrigerator while on the road. I really need to be able to charge from my alternator, even if it is slow. How do you manage your refrigerators while on the road?

[@Jasonoid]

While on the road and while driving, I run my fridge off my 12v accessory port in the back of my 4Runner, I custom installed Anderson power ports and ran 8 gauge wire to the back. It works well and I don't have much voltage drop over the distance. While camping or when I'm not driving I run my fridges off this Lifepo4 battery. I charge it via a combo charger. It's a Kisae DTM1250. Check it out the, I bought one and I love it. Little expensive but very customizable. Solar MPPT and DC to DC Charging in one! I bought it off Amazon.

[@quinbus51]

After looking around (and being appalled at the prices for DC-to-DC chargers), I've started playing around with DC buck boost converters you can buy on ebay/Alli Express, etc. These are basically self-contained power supplies that feature constant voltage and current and will easily step up or step-down voltage from inputs between 5 and 30 volts and outputs of .5 to 30volts. They are pretty limited to relatively low amperage (usually less than 4 amps), but for my purposes it should work, I think, for slowing charging my LiFePo4 battery from the car's electrical system while driving. There is also a timer feature that will turn the output off after a predetermined amount of time. There is the added plus of now having a self-contained module that can be used to run all sorts of less-than/more-than 12 volts in my battery box. The model I'm using has a display built right in, so it's very easy to dial up the desired voltage and amperage requirements to run fans, worklights, etc that may be rated at something other than 12 volts. I'll report back with details of my testing....

How about next time we double the battery & add a 2000 watt inverter?

[@wjf213]

@@Jasonoid That's what I was thinking. Some thing to run a refrigerator when the power is out, and can be recharged with solar. Also, maybe build the basic battery, BMS, 1000 or 2000 watt inverter, solar charger, and then have it so we can build more batteries in the future and daisy chain them for a larger and larger bank. I know the battery is the big expense, but maybe build an "EMERGENCY" box using deep cycle lead acid for now, and then upgrade to lithium later when more funds are available, but at least for starters you have some thing for an emergency that can be used hard for a few weeks if need be. A 1000 watt inverter to keep a refrigerator going, run a microwave, TV and basic charging of cell phones and what not, or upgrade to a 2000 watt to maybe run all that, and a hot plate or some thing for cooking on. It's a lot of power being drawn, but that's why you can daisy chain batteries as needed, and have a couple solar panels as well. Personally, I'm not building some thing like this to take camping to air up a mattress, or charge batteries for tools, I mean that's cool and fun and all, but for "ME", I'd spend a few hundred more dollars and make it really usable for all that fun stuff, AND FOR REAL emergencies. Some thing for REAL emergencies, it should be able to be recharged from the grid or gen set, solar, and a vehicles charging system. I'm in Louisiana, and we lost power for only 14 hours a few weeks ago when the hurricane hit, but if I was just 40 miles west in Lake Charles, I would be without power for weeks. I have a gen set, but this would be great to use along with it. Some thing else that would be handy I think, is a built in retractable extension cord mounted, probably on the outside. I'm thinking some thing along the lines of a vacuum cleaner cord, as they're pretty durable, can handle a good amount of power, they're cheap, compact, around 20 foot long cord, and easy to mount. Of course you'd have to replace the male end with a female, but that's no biggie. Now you really do have a very handy self contained box. For reference, here's what I'm thinking. evacuumstore.com/p-311-electrolux-plastic-canister-cord-winder-assembly.aspx?gclid=EAIaIQobChMIo-CGl87r6wIVEdbACh2uoQQjEAQYBSABEgJ7jPD_BwE A bunch on ebay. www.ebay.com/i/312867187883?chn=ps&norover=1&mkevt=1&mkrid=711-117182-37290-0&mkcid=2&itemid=312867187883&targetid=935694488106&device=c&mktype=pla&googleloc=9025259&poi=&campaignid=10877145111&mkgroupid=105798873063&rlsatarget=pla-935694488106&abcId=9300400&merchantid=108357416&gclid=EAIaIQobChMIo-CGl87r6wIVEdbACh2uoQQjEAQYASABEgID-fD_BwE Keep up the great work.

i wanted to build something similar except include a solar charge controller as well. should i wire in the positive of the charge controller to the main breaker, or direct to the battery? if i go direct to the battery will the charge controller always be on and draining my battery?

[@Jasonoid]

As for draining the battery it depends on the charge controller. Most have some sort of parasitic drain. Its good to fuse that connection so I'd put it behind the breaker if I were you.

[@jbadallas1117]

Hello. I really liked the video and it has me wanting to try and build my own box too. I did have a few questions though. The batteries in the link are now $159. Are they the correct batteries? They are much cheaper than what you originally described. What AC charger do you recommend? Also, if you use a 100 watt solar panel to charge like the Rockpals, do you need a charge controller wired in or does the BMS serve that function too? Thanks for your informative work!

[@Jasonoid]

You'll want to have a lithium based charger to charge it properly, those can be either AC or DC powered. There are multichargers available that support more than one input, for example solar, DC or ac charging. (check out the Kisae DTM1250, it's amazing!). The price of batteries have dropped significantly because the larger 280ah cells are very popular right now. You can always spend more money for these types of cells. With cheap batteries you'd probably get around 95% advertised capacity, which I think is worth it for the cost. An active cell balancer is usually required for unbalanced cells, you can get a pretty cheap one off Amazon, it worked really good for my battery pack. Will Prowse has a couple videos on the subject. Just plan to get good at soldering. It's been such a fun project and I have learned a lot. My next build will be a bigger 280ah build. Just saving money for those batteries.

[@chartphred1]

Quick question. If I wanted to build a 200amp Hour box, would I need a BMS that is rated to 200amps? If so, any on Ali-express you can recommend?

[@Jasonoid]

They don't make 12v 200amp bms units because the amps would be crazy high. If you want to run 200amps you'd want a 24v or 48v battery. I think Will Prowse has a couple higher amp units he's recommended on his channel. I have a new 100ah battery I am making from Battery Hookup in the next couple months. I'd recommend checking out their 100ah modules, they are a great price and super compact!

[@Jasonoid]

All Lifepo4 batteries are technically deep cycle. You can discharge them 80% without permanent damage. 20amps is a lot of power draw. If you want the battery to last longer than 3 hours you'd want to get something larger but use the same principle in my video to build it. 200ah or even 280ah batteries have come down in price quite a bit recently. If you have room for a larger battery I would recommend a larger capacity. I only have an average of 5 amp draw and my 80ah battery works great for me.
