      Any chance of getting a wiring diagram or instructions so it is a bit easier to see what components go where? I've got a good idea but it is always handy to have a schematic to check against before its first use.

      Someone else probably already said it but a few great alternatives to the dean connector solution would be XT90 connectors, medium sized powerpoles, and potentially a medium sized SMH connector. They would have only one correct orientation, but you wouldn't have to make custom connectors for everything you want to attach to it in the future, just crimp/solder and go :)

  • FullyCrafted

    If the battery pack is around 1500W and it outputs that to the step down regulators can they handle that? Or does the BMS regulate the wattage it outputs?

    Really high quality build. My only issue is that a build like this kinda defeats the purpose of diy. The amount of money spent on the new cells, the top of the mark bms and the overkill safety measures, along with the cost of the inverter would go into the 4 figures. With that amount, you could just buy a battery power station like the bluetti. But other than that, really top notch!

    • Kristopher Blakeley
      Kristopher Blakeley

      The bluetti EB150 is the most comparable unit, only has 45w PD output, rather than 95. It's a good option, but it does not meet all the same specs this does. Plus with this you get to say you made it.

    I love your content, but ... can we skip all this VPN misinformation? As a Software Engineer I find it kinda unethical ... to spread such misinformation to the public. VPN are not to protect you from fingerprinting and websites knowing who you are. That is already done from you simply signing in and using any account! Simply by using your google account to login to youtube or gmail or any google service you've already exposed yourself everywhere. Or facebook account. Any kind of account! For anyone who really wanna investigate more ... Here's Tom Scott doing a brilliant job at explaining it You can tell the legit reasons why you would need a VPN that are both true and reasons people actually really mostly care about. Like watching Netflix from another countries, Hulu, or other country-locked services. Instead of spreading ... lies. Kinda dramatic word but you're technically doing exactly that. We're all responsible for not spreading misinformation, we can't just blame everyone else but when we do it "we're innocent" and downplay it. Love your content. Wonderful job with the battery! Keep it going!

    okay so the batteries cost about 400$ and for a backup battery similar to this is about 500$ and the 500$ supports solar panels (not included though) seems like a lot of safety risk and time for 100$

    Yeah, a great project but I’d never attempt it. A bit too dangerous if I screw up. Though it sure beats paying $1,500 for a Bluetti. Hmmm... where’s my credit card.

  • Blotted

    Ive always wanted something like this and I know they exist online but theyre soo expensive. I just went the route of buying a small generator that does the same stuff at 1/3 the cost. I know their is a crap ton of better uses for a giant battery bank like this though. Great or doing everything a generator can do without the noise and limits. I wouldnt watch movies on my laptop at while camping with a damn generator but I would definitely need all the extra power from a power station. Theyre pretty awesome but again, super expensive and most the time they're some chinese brand that you dont know is decent or not. If anyone has any suggestions to something specific to what's built on here that's a decent deal and product let me know

    Hey. @DIY Perks, have you seen the guy who made his own, DIY "Powerwall" in the US? He powers it with solar and managed to get completely off-grid with it. Better yet, he uses recycled cells - taken mostly out of used laptops, cause it seems that a "broken" laptop battery, usually has only one or two broken cells inside, while the rest works with no problems. Would you ever consider something like that?

    Very nice battery pack 9:50 you are not only electrically insulating the contacts but you are also thermally insulating the battery pack. This means that any heat that develops in the battery is not able to leave the pack as well as it should. High energy packs are often lined with special silicone like material that directly attach to the metal case or even a heat sink. Especially when delivering high power over longer times it is very important to do this. Also, make sure there are a few temperature sensors to the BMS such that the BMS can switch off the battery when the temperature rises too fast or gets too high. As a safety warning: never ever suggest that people use old or refurbished cells to create battery packs with multiple cells, especially when those cells are placed in parallel. Any two cells that are placed in parallel will charge/discharge each other when these do not match. Not only the battery voltage but also the cell's capacity and internal resistance are very important. If these are too far out of alignment, the better cell will start charging the other cell(s) with uncontrolled/unlimited current (or as much as the better cell or cells can deliver). The cells you use can deliver up to 45 A per cell (not 30 A as stated by fogstar) when short circuited. So if one of these cells fails, you have a possible fire hazard. To prevent this happening, the BMS monitors the batteries over their life time and the BMS will shut down (and refuse to charge or discharge) the pack. The BMS will/should also monitor the temperature of the battery and with a large pack like this, there should be multiple temperature sensors on different places in the pack and with a pack like this I prefer to use 2, or even better 3, sensors. Note that even most electronics engineers have no clue on the use and care for rechargeable lithium cells. I have been working on multiple types of rechargeable technologies and have designed and built BMS systems on and off for the last 20 years. I know enough about Li-Ion, LiPo and LiFePo to know that I am not an expert on this ... When making a large pack with parallel cells, I would stay away from the BMS you mentioned in choice 2 and 3 (the "Small Daly BMS"). I base this on the label on the product that shows the text "with balance". The "M" in BMS stands for "Management" and that involves not just balancing but also monitoring the state of charge, temperature and capacity delivered over all charging cycles. As soon as this suddenly changes, the BMS must warn the user, at least by disabling the battery pack. If a manufacturer feels the need to specifically note balancing on the label this suggests to me that this might most likely just be a protection circuit with balancing. These protection circuits do not contain any electronics to "manage" large battery packs. The TinyBMS is the only sensible choice for this pack; it monitors voltage and current of each cell stage, monitors SOC, keeps track of number of charge/discharge cycles, starting capacity, last cycle's capacity and I think it will even show you the "health state" or "age" of the battery which predicts when your battery will fail. The TinyBMS also uses the temperature sensors to prevent charging when the battery is too cold. Future firmware updates might even contain a special features that start pulse-charging or slow charging when cold and only switch to full current when the battery is up to temperature. About "refurbished" batteries: Refurbished cells are a myth, these are just old cells recovered from a pack where other cells have proven to be faulty. Never ever combine those old cells to create a parallel pack because you do not get any clue on the age or life expectancy of such cells. You can buy things like "refurbished" E-bike batteries. Those contain NEW cells that are placed in the old housing with the existing BMS. The BMS is reset in order to keep track of the new cells states like current capacity and pack age. Such refurbished packs are as good as new ones from the factory. Some brands will even recycle BMS systems themselves, they have a system where a dealer gets a discount on a new battery when returning the old one.
