When I was a kid we had the VW camper with the pop up top. It also had a tent you hooked onto the side. It was dope. My brother had it at college and one day it caught fire and burned to the ground on the side of the road. RIP VW camper. 😪
Thank you Jehu, please keep these videos coming! I received my 4 batteries from you today and I am so excited to have these as the base of my soon to be solar system! I will definitely balance them as you have shown, and am looking forward to checking out the 48V charging setup.
You don't need a $30 balancer to balance your cells. I balance mine by just hooking them in parallel. I have two connectors. One hooks them in series for source. One hooks them in parallel for charging. You can make up the connectors with Anderson power pole.
Jehu why you don't share the links on a more international site like AliExpress aswell, so for example in Europe I can buy the same things that you are using in your videos
While this is interesting, the power wall was basically pre-wired for the 8s battery balancer. What about balancing a 48v battery pack with an 8s balancer? Balance by cell groups? Balance part of the pack at a time? Is this possible?
Saw a reply on another video about modifying these from 16S to 14S to lower the voltage to their inverters. The built-in BMS kick in when the individual cells reach 4.05V. But they do not have a way to monitor externaly, other than checking each cell. See comments and replies. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fqWXsxpR56s.html
I Need to pick a couple of those devices showing the voltage. BTW same guy that lives in Ca (south bay). I am building or should say repairing my e-bike(2) battery packs they both stopped working just under 3 years. Just getting into this area as a hobby/family fixer. The biggest slow down of this repair process is charging then discharging and finally charging each cell to get its capacity and voltage. How do you cut down on time when it comes to this step?
Hey Jehu, can those balancers be used in series to display cell voltage (and slowly balance) a higher voltage single pack in an EV ... perhaps by overlapping connections, so every 8th cell is connected to the neighbouring balancer??
Hi, is there a good bms to use for this? Or will there be a follow up video to use the built in bms? Or if I just connect it to the built in one it balance the batteries but no read out?
I have 12 of these now (thank you), and am working on the built in BMS. If I wanted to share this data, where would be a good location. I have the basic design of these, and how to interconnect them. I am working on the management interface which can support up to 32 units. Once I get this last piece, up to 32 units can balance with each other across the packs.
I also have several of the Samsung battery modules. The BMS controller is a Maxim MAX17823 there is some data out there but I am working on an interface as well
I'm very interested in this. Wondering if making a public Github repository is appropriate? Otherwise, I'd be happy to build/host a site with the info that you're willing to share.Thanks!
@@indigoskin Github is great for schematics and code. I am putting a Wiki together to allow elements of information to be linked. If you would like me to include your Github, let me know.
@@devdaad I just received the balance coils for the network today. I will need to mount them and prototype a board, then get a board made. Follow at the wiki above...
Hey Jehu, I'm confused. the connectors that you linked to on Amazon appear to not come in the 4pin and 5pin that we need to use the Battgo cell balancers. Are we supposed to cut them down to the correct pin count? Seems like I'm missing something. Thanks
once again an amazing video, thank you so much. Quick question any idea on how to get hold of an BMS with wifi? I assume ISDT BattGo BG-8S Battery Meter is offline. Basically, I have looked online and can't find any. It will be great to check status of my battery packs remotely :) thanks again and great work :)
Hey Jehu, love your content...and now probably a dumb question: could you tell me why the cell and total pack voltage goes up, with resistor-type balancing? Or were you charging at the same time? Succes with the Samba, looking forward to see the video 😃
@@jehugarcia have you paralleled the pins into the electrodacus? It could be used to charge the batteries (when changed to 24v with cables) 3.3v to 3.9v.
thanks for sharing Jehu BUT you haven't given us an update on how you charge the Samsung SDI ESS 16s 60V battery modules. Please give us an update...and someone this comment so Jehu can see it. thanks!
Would you be willing to do some consulting for me so I can custom build my own system kind of all home encompassing solar gen grid tie and battery back up for full off grid capabilities
If you actually take the time to see all of his videos and do a little research, I guarantee you will know enough to build your system without the need to pay anyone... fatcs 👌😤

Hello Jehu. I need some urgent help understanding how to make the connections to charge this BMS "ISL94202EVKIT1Z". I'm building a BMS for a hospital application with my team and we're trying to test this BMS evaluation kit first. If anyone has used this device or understand how it works please let me know, it's for my senior project.
I have same device. It is useless... It can take 2-3 weeks to balance a mid powerwall if I never charge it at the same time for 2-3 weeks... only using it for monitoring. I regret buying it.
