diyBMS Upgrade

[@StuartPittaway]

Great video - worth mentioning that the 5V input has no over voltage protection - it does have reverse polarity protection and a fuse. The watchdog isn't currently populated or available yet.

[@AdamWelchUK]

So no more than one smidge over five volts. Gotcha! :-) Cheers Stuart

Instablaster...

[@MaxGoddur]

Just ran into your project and it looks promising and interesting will now go back and review your previous videos to get up to speed. Thank you for creating them and the project.

[@fredflintstone1]

Nice to see a new video from you Adam:-)

[@AdamWelchUK]

Thanks Fred. :-)

[@sjdtmv]

I have 5 of these controller boards on the way to trial, Stuart Pittaway has made great leap forward on these diyBMS.

[@RaithUK]

Adam/Stuart great video and hardware. Loving where this is going! Keep it up.

[@AdamWelchUK]

All Stuart’s work really. Cheers Raith.

[@pauludrea4082]

Thank you Adam, I find your explanations clear to follow. It helps me setting up the BMS. Thank you to Stuart as well for the great work he is doing; I watched all his videos and obviously subscribed to both channels, yours and Stuart's.

[@johnnodge4327]

Nice to see you still at it Adam. Very comprehensive update on the DIY BMS. Thanks.

[@AdamWelchUK]

Cheers John.

[@GadgetAddict]

Great update. Thanks for going over it all👍

[@AdamWelchUK]

No worries. Good to hear from you GA.

[@Luke-san]

The sun is back ... guess we are all starting our nice little projects again. Great video Adam!

[@AdamWelchUK]

Absolutely! Cheers Luc

[@andresgodinho]

Just started programing the 4.21 modules! This is so good!! Portugal has a fan ahahH

[@Magic-Smoke]

Good to see you back with this upgrade Adam!

[@AQUATICSLIVE]

Yeah, that is cool RS485 coming. I use it along with MQTT for all my systems now. I have the PZEM-017 current shunt if you want to try that one. I just built a large monitor system with multiple shunts, one for each major item.

[@trickyriky1]

Slightly jealous... I managed to melt that nice controller board you sent me and had to build a temporary measure, went with the d1 mini pro this time around. I'm also in need of 1 but maybe 2 or 3 v4.21 cell module boards as my now 14s pack only has 13 working modules lol. That new controller looks impressive but overkill for me... :)

[@electronic7979]

Nice video. I liked it

[@matthewknight5641]

Id love to have a good bms for my leaf powerwall. Ive been using it for a year with no bms but i hear its dangerous. If you have any advice for the 24 volt leaf power wall please let me know. I can tell you really know your stuff and i trust your opinions as to what i should buy and install

[@RWBHere]

Thanks Adam. At 15:22 is that missing temperature data a result of one module being different to the others? Do you have a software glitch/bad connector/faulty output? Maybe that Version 4.2 board is not outputting the data, and data from the older boards could even be shifted to one side, rather than leaving a gap in the display. It's worth disconnecting/disabling that board temporarily to see what happens to the display.

[@AdamWelchUK]

The board not reporting temperature is the one with the ceramic resistor rather than the surface mount solutions. It’s likely either I’ve not soldered the thermistor correctly, or it’s damaged under the power resistor, but I’ll have to remove the resistor to find out. I’ll probably check that when I get the proper resistors. Probably not video worthy, but we’ll see.

[@RWBHere]

@@AdamWelchUK Thanks. So it's some work to do, but probably easy to sort out. Awesome job, nonetheless!

[@nich532]

Great content..... are you disposing of the 3.0 version...

[@AdamWelchUK]

I need to find some use for it if I can.

[@RWBHere]

@@AdamWelchUK Or a buyer... 😉

2.5 years since the V3 update? Wow, time flies! Adam, are you still keeping an eye on cheap charge controllers? I'm looking for a cheapy that can safely charge a 3s li-ion battery pack and found some $20 PWM controllers that claim to stop charging at an user defined current...

[@mr.makeit4037]

Yes I want 10 amp mppt pcbs. Plenty of 5 amps. Maybe a video to upgrade to 10 amps

[@chrisfairbrother9197]

Good stuff Adam. The link to Stuart’s youtube channel, doesn’t do anything on my iPad?

[@AdamWelchUK]

Oh ‘eck. Thanks, I’ll check.

[@CrAzYDr1veR]

that new controller would look nice in my car :P

[@AdamWelchUK]

Is it an ev? :-)

[@CrAzYDr1veR]

yes i will use the new 32s option, it's a peugeot 106 same as the saxo that were PSA first gen of ev's. Good car for diy.

[@DIYwithBatteries]

Nice video Sir :D

[@piconano]

Very nice.

[@caroman6761]

Did you solder all parts by yourself or did you buy them somewhere already soldered?

[@pcmalek5]

hi adam big fan i have a question about your epever dashboard , i am setting up my own for my epever UPower inverter charger . i am using ubuntu, python, influxdb, grafana and everything work fine except for the 32 bits register conversion, for example PVwatt is split in two 16 bit data high and low . i noticed that you did a bit of program to solve this issue , i hope you can share your solution . thank you adam

[@nich532]

where can I get the ket for the Diy BMS already build and program

[@pulesjet]

All well above my abilities. LOL

[@grahamepigney8565]

Great video, but even as a a techno-anorak it lost me around I-squared-C at about 50 seconds. Would probably help people if it was in plain English.

[@GDMHificationranpitc]

ok how do i get back to the beginning a capacitor does what?

[@cgmarch2359]

Hi .Any iddea on how much costs to have jlcpcb build v 4.4 (pick and place)?

[@dittagecoeco2738]

I have got 30 cell modules for 75 euros populated and shipped to Italy (no attiny tough, as per pittaway's GitHub explaination). The newest esp32 controller were 64 euros for two of them (minimum quantity), but they failed revision process and i decided to go with the simpler 8266 controller (version 4), which were 15 euros shipped for 5 pcbs

[@montaguemonro565]

Hi adam, perhaps a silly question, but is this possible to use with Lifepo4?

[@AdamWelchUK]

Not silly at all - yes it is. I already have one fitted to my 4s3p lifepo4 bank. Works perfectly.

[@sunuk1915]

Passive topology wasting powers

[@aclam9839]

In video ads ?? that's me unsubscribed !!!!

[@AdamWelchUK]

It’s default now for KZbin. You can watch my videos add free on odyssey / lbry if you’d rather.
