Salvaged Tesla Batteries for Off-Grid Power?

[@Electronzap]

Nice, looks like building those would be a good side business for anyone who comes across used Tesla batteries often.

[@edc1569]

They’re not cheap as the people doing ev conversions want them

[@valerieewing3306]

Excellent work, well explained and concise. Thanks for the overview. Will be in touch.

[@tilroh]

delighted to see you've made using Tesla batteries practical. About what is the capacity of a 6s module?

[@OverkillSolarLLC]

The ones we have in the shop were 5 kWh when new in 2014, now they are testing at 3.6 kWh, 77% of original capacity. A video about the capacity testing will come out in the near future

[@markpirola8152]

Nice work. Understand instructional. Consider amping up the safe practices… pun intended. Simple plywood covers to drop over the battery modules would go a long way towards keeping accidental electrical shorts at bay. Also consider having your tools plastic taped. Love this re-use approach.

[@Visionery1]

Nicely manufactured product!

[@dustman96]

Why would you need to replace the stock bms?

[@dalehair2400]

Good video, well done.

[@italonelli1233]

You can bypass BMS just for power output and use the bms only for charging that way you are not limited by the bms amperage limit

[@dermo-hk6pu]

when will these boards be back in stock

[@mikejf4377]

When did the BMS revisions happen?

[@TimothyYancy]

+++ How do you charge the battery pack? We see how to get output but not input. Thanks

[@Ryukachoo]

Dont bother with the model S modules for offgrid storage, theyre good and small but have become very pricey per kwh due to popularity. The real cheat code is the model 3 battery packs, almost no model 3 needs battery replacements and people are sleeping on them for battery storage so you can get a huge 75kwh pack from the original long range models for like 5 grand from a junkyard, $66 a kilowatt hour is absolutely insane

[@dougiee6589]

Excited and commented before I even watched damn

[@himentaroul]

Hallo i habe already one overkill bms 16s. If I will buy Tesla Universal BMS Interface Board will work with my old bms ? Btw nice job keep it going and stay safe

[@cbmecheng]

Do I have to have one kit per Tesla module?

[@freerepublicusa2064]

I have a DC mobile solar trailer and the flooded classic lead batteries are going bad, I wonder if I could use used Tesla car battery modules as a suitable and longer lasting replacement? Please let me know if this would be suitable, thanks!

[@EVForge]

What brand inverter? Curious how 6s is working for LVC. 7s seems more inline with most low voltage cutoff for cells to cut off at ~3v per cell.

[@GauravVermaGoogle]

I need around 20kwh of storage. Can you point me to a video where this setup is scaled with tutorials please 🙏

[@NicoMeyer-z6m]

Hello, I just bought the Tesla BMS Kit and am wondering if the app and BMS can reliably prevent charging if the battery temp is too low and prevent over discharging and/or overcharging?

[@walkingconifer]

Is it possible to build a 72V pack using this BMS?

[@Rdsw-techBlogspot]

I have 2 Tesla module, so I need 2 BMS ?

[@Dakalberry]

Can it be set up with 8 modules and a 48v SMA sunny island inverter, can the bms communicate with the inverter?

[@hing983]

nice i m looking for it

[@richardknieper973]

Awesome !

[@stufq]

Why take battery apart? Is safer, easier use the whole battery with battery emulator...

[@icarus901]

How many 6s tesla modules can be wired in series (with a BMS per module)?

[@OverkillSolarLLC]

We suggest only 2 in series for safety reasons but if you must have more voltage there is no technical limitations due to the BMS. The Tesla pack puts all 16 modules in series for 400 volts.

[@306familyfarm]

do you offer a 12s bms to run 2 batteries with only one 48v bms? @@OverkillSolarLLC

[@kjtwist]

I really want to buy these but don't understand how I could put them together in a series and then parallel multiple 48 Volt packs. One battery does not really make for an off-grid solar home. It would be awesome if you made a video show this, a rel world application using your system. @@OverkillSolarLLC
