Well done! Could you share link to small crimper?

Hey great video thanks for this with the middle bracket did you have any issues attached 1 slider each side ??

Very nice, thank you for sharing. I just want to know, why you compress the cells ?

Just stumbled on your video, great work!! Thanks for sharing our website, MUCH appreciated :)

Howdy! Nice Job! How many inches of clearance did you have underneath the bed?

You haven’t provided any ventilation, the BMS won’t last long running under them conditions.

Very nice design. Thank you for this video.

Nice little set up. I need to get a 3D printer. Did you use any special plastic?

Is that really "aluminum angle iron"? It looks like zinc plated steel. Where did you get it? Do you have a brand? Thx

Why do you make so many mistakes during construction?

用木板可能不是太安全

If you haven’t already replaced the bolt on your Lynx distributor, you should be able to retap the bolt and use it.

could do without the sound effects..............................

Hey mate, do you have a link for those raised therminals?

With the Dimmer + Solar PV, self-sufficiency will now increase to almost 95% in summer, which means a huge breakthrough. The prerequisite is that you have at least a small balcony power station, and you don't need an expensive battery either. Example of a kettle: Without a dimmer, the 2500W - 600W PV system needs = 1900W, which you have to pay more for. If I turn the kettle down to 600W with a dimmer, then every weak PV system can now supply each consumer independently and independently, because the 2500W kettle becomes a 600W kettle thanks to the dimmer. Magic... The 2000W e-heater becomes a 500W e-heater with a dimmer, which can run 12 hours a day free of charge via PV. th-cam.com/video/QbLWDbJi6ew/w-d-xo.html . The 4000W oven is also tamed. Not the solar systems have to grow, but the consumers just have to drop by 75%, which is sooo easy with the dimmer. are you convinced now I have already switched my entire household to dimmers. Please have a look at my channel. ............. 🌞 ............ Increase mini PV solar self-sufficiency (winter and camping): A boiler and other power-hungry consumers can be infinitely reduced using the "5000W dimmer". Ebay €7. I run 5 dimmers in parallel on an 850W inverter. Kettle 2.2KW at 150W runs 12 hours a day, so the water is always hot. The room is also nicely heated. 2.5KW washing machine runs in parallel with dimmed to 400...600W and always reaches its 60°C, and also its 1400rpm... It doesn't matter to the washing machine whether it changes the washing temperature to 5min@2500W or 100% can be achieved free of charge via existing PV power in 20min@600W. The wash cycle lasts the same time dimmed and non-dimmed, 3Sth 10min. The iron, dishwasher, oven, electric heater, waffle iron, coffee machine, all internal heating are throttled with me. Videos on my channel th-cam.com/video/eC2olbCBhh0/w-d-xo.html The inverter stays cool, quiet and the MOSFETs + (battery) remain intact because no extreme current peaks arrive at the inverter. Now every Mini PV Inverter is enough to sell large devices. So, with the dimmer, all internal heaters/devices can be converted into base load devices that stay almost permanently ON, drawing very little current directly from the PV. With a wattmeter / energy cost measuring device you can then measure this perfectly in order to set the dimmer optimally.

the aluminum case is connected to the postive terminal through leaked electrolyte from manufacturing. Some cells are worse than others. Usually around 10-30mA of current flows if you provide a short from the cell case to your negative terminal. That's about the same amount of current to power your BMS. It will run your battery down over time. I used 1" cargo straps. I use high temperature polyamide tape between my cells and covering cell terminals/busbars. I use quarter inch ceramic fiber cloth around the whole battery to prevent wood from catching on fire in case of a cell malfunction.

Nice job! Well done! Music was too blaring loud tho. Greetings from Jamaica.

Great ~ Job with the Battery Compression

Great - Job

Great video man !!!

do you know if stainless steel posts would work instead of aluminum?

Thanks for sharing! Thats first proper video i found of good DIY box for our cells. Ive made few boxes for 100Ah cells but never liked end result. Just came into possession of 8 of these exact same cells and will copy/reverse your boxes!

I am glad to see that you got to built a diy pack. You seem very knowledgeable and even then there was nearly a problem when topping off your cells. Imagine how many people out there were not so lucky

That is a really nice looking DIY box. Couple of comments I gleaned from my own experience. I'd like to see a non-conductive layer on top of the battery for safety. Clear acrylic sheets work well. Not sure why you used heavy 3/4" plywood for the box. 1/2" or even 15/32" is very strong and lighter. The Blue Sea terminals are nice, but I would have set them with the mounting screws on the outside of the lid. Covers the drilled holes and looks much nicer. The aluminum flat bar between the threaded rods is doing nothing but adding weight and not strength. If you run a screw through both sides of the box into the compression plates on the ends of the battery it can't move in inside the box. That works well if you are using it in a RV where vibration can make the battery assembly walk inside the box. I am in the process of building a similar box for a 412ah battery. Insulating it with foil faced 1/2" polyisocyanurate sheeting to keep the battery warmer in cold weather and cooler in the summer heat. You did nice work. The hinged lid was something I like a lot. I was going to just screw my lid down, but I may use hinges now.

Hi, excellent video. Do you happen to know the final external dimensions of your boxes? I would like to make one for my van, and I have a space that has a max size I can fit in. Thanks.

I made up a pack last spring using 4x 320amp cells as they were on sale - like you I used a blue tooth 120a BMS but with 3 x 8AWG tails from each post - I put a self addesive insulater between each cell and clamped them between 18mm ply and 3 HD industrial nylon cable ties - I equalised the cells in parralel overnight just using crockadile clip fly leads - they were all 3.3v. The next day I assembled the pack with balance leads and BMS - I fitted an additional set of balance leads to a second JST outlet so I could charge with my T8 charger which ballances up to 15watts as it charges, I disconected the balance leads from the BMS and charged the pack to 14.6v at 20a - which is 3.6 - I then remove the charger and reconnected the bms - all cells arrived at 3.6v beatifully balanced - from now on the pack will only be charged to 14.2 or 3.55v max. The Pack is used on my RV and hooked up to a 1500watt ( 30000 peak) sinewave inverter when needed - its charged by a 280watt REC panel and EpEver MPPT charger with Renogy DC to DC 20 when motoring and 30amp dedicated charger when on hook up . After a summer of heavy use charging ebikes, her hairdryer, microwave etc it has performed brilliant and never needed additional balancing - often the solar is more than enough, once full it dumps into the small 4 gall water heater.

LOL

Always like seeing things like fan speed switches getting fixed. I sure would be tempted to leave all that glue there and just cover it up. :)

Fortunately, power was restored a few hours later. To absolutely nobody's surprise, Woods Boss Brewing (where this took place) is going to brew a beer named for this event. Stay tuned...
