I have compressed the cells with some duct-tape, I know it's not ideal, I will probably make a brace out of metal in the summer, when working outside is easier :) Indeed these cells already have a quite sturdy case and don't really require compression. EVE-cells or aluminium shell cells require...

Good morning everyone, I have made some progress on my MiniEL, but I'm facing some issues, which I'm solving one after the other :) Batteries and rat nest The previous owner had wired 4 lead acid batteries in the City-EL, taping the electronics on the 3rd battery without balancing the batteries...

I wonder if there is any details of his software and custom boards that he made for his MiniEL.

Thank you, through my research I missed this page on the Wiki! I looked for quite a while but couldn't find it. Thanks a lot!

Good afternoon everyone, I'm looking for inspiration about the battery heating. I'm going to put some hard foam boards sandwiched in cement to insulate my batteries a bit better, but I also want to be able to heat up the batteries before charging to be able to charge in cold weather. I see...

It's a Huawei R4850G2, it's a power supply for telecom equipment repurposed for this.

The EVSE can instruct your charger to lower the power. It's important that your charger listens and acts...

The microcontroller Could be able to limit the power usage to respect the maximum current of the EVSE.

I have bought a Huawei R4850G2 as well and will try to get it working with Type 2 public chargers. I will probably make a PCB with a microcontroller and if I get something working and nice, maybe sell it :)

It's indeed a Titan Thrige with a Curtis controller. My Mini-EL is from 1992. It has over 170'000km. I have found the ELWiki, which is an incredible source of information, it's really nice to have this! I read a lot on it. For now, I'm reverting changes made by the previous owner as his sense...

Hi everyone, I've been browsing this forum for a few weeks and recently bought a Mini-EL. I live in the Netherlands but I'm French, I hope it's okay that I write this in English. The Mini-EL had been previously "converted" to 48v by simply adding another battery in the cargo area and wiring...
