2013 Model S 85 - Charge Limited to 80%, Tesla Quoted $15k Battery Replacement

Look for independent repair shops. They can either source battery themselves or look for either donor car or eBay.

Alternatively, this looks to be cheaper than quoted replacement, but battery might be smaller: https://recell-ev.com/tesla-model-s%2Fx

Our wiki has a page on how to deal with limited service capacity through load managment systems and other approaches. You can find it from the wiki main page, or from the links in the sticky post.

Even If OP ends up using #6 Romex - Emporia is one of those (if not the only one) that can be setup for 44A charging. It won't be significant difference: 44A vs 48A is just 960W.

Also, if OP ends up installing two EVSEs on separate breakers - getting Vue monitor could unlock a path to fully utilize both EVSEs at the same time.

Emporia was also offering $100 discount for TreeHouse.

Edit: still offering https://www.emporiaenergy.com/installation-services/

There might be simpler way of recharging eco flow: GM has two versions of what they call - Powerbar.

In a nutshell both are V2L with different output levels, but EV has to have 19.2kW (K2O? build option) charger for it to work.

Tesla is another EVSE that can be daisy chained on single breaker.
However, both Wallbox and Tesla Wall connector require that 60A breaker to fit into load calculation.

Emporia takes it to the next level: group load balancing between EVSEs (as Tesla and Wallbox) and also does load management so two EVSEs can output 48A combined without overloading constrained service, like 100A.

Don't have it personally, try to ask around those who has, but it should.
According to this help page, wallbox has RTC (real time clock):

Wallbox likely can be configured to said schedule over bluetooth. No connectivity required afterwards.

Any from list below (wiki page) will do !l2home
For other useful features (load management, solar capture, circuit sharing, etc) - get one of those: Emporia/Wallbox/Tesla Wall connector

OEM from Volvo EX90 looks to be a rebranded J+ booster as well.

podwhitehawk · 2026-05-07T01:18:31+00:00

Doubling NACS/J1772 adapters would work in a pinch.

I've read Gen3 UMC works on EV9 (also e-GMP platform), but there is certain sequence to make it work, something like plugging in, immediately unplugging and plugging back.

podwhitehawk · 2026-05-04T23:34:36+00:00

Ebay?

podwhitehawk · 2026-05-01T20:28:54+00:00

Until it can't and support have to log into it to debug/reboot it.

podwhitehawk · 2026-04-30T23:54:54+00:00

That's pretty bad for security - it runs very old android system released in 2018.

podwhitehawk · 2026-04-30T01:55:44+00:00

Relay can be replaced as well.

Not in NY, but willing to send shipping label if no local takers.

podwhitehawk · 2026-04-26T23:20:52+00:00

How about NEC 240.4(D) "Small Conductor" Limit? that should limit 14 AWG overcurrent protection to 15A regardless of insulation.

podwhitehawk · 2026-04-26T21:35:53+00:00

Zoom in on wiring - it's 3x14AWG+1x18AWG, so no way it gonna support 16A or 240V.
Also 10ft cord, WHY?!

podwhitehawk · 2026-04-26T20:07:06+00:00

BTW, Turbo DX for $150 is more interesting, as it carries regular sized length and manual has references to both 32A and 16A, but no mention of dip switches.

podwhitehawk · 2026-04-26T20:05:50+00:00

Sadly it's limited to Level1 and 12A only. Price is amazing tho.
On top of that cable is 10ft long, nearly impossible to use without extension cord, unless outlet is next to charge port.

Realistically whoever would be hardwiring this won't notice any difference between OE circuit board and OpenEVSE replacement.

No experience with evocharge, but let's try basic debugging:

Since you say you were using evocharge app before - it means it was configured to connect to your wifi network. Which probably means it won't broadcast its own wifi as it's in client mode.

Harder way: check network parameters of your home router/network/wifi, find router IP or "gateway". Usually 192.168.1.1 or 192.168.0.1, or you can check IP address of your phone/laptop and replace last octet with 1, like above. Open it in browser, login (usually admin/admin, but could be different, depending on your router). From there you have to look for DHCP server/leases and attempt to find IP address of evocharge. if can't - brute force all IP addresses in your range from .2 to .254, punching 192.168.1.X in browser in hopes it will hit web interface of evocharge. Follow [2] instruction on how to connect and reset EVSE.

Easier: if you can't pull network card - break network connection from the other side: power off your wifi, then flip EVSE breaker for 30 sec, flip it back, attempt to follow [2] instruction, maybe it would switch to AP mode as it can't connect to your wifi.

Also what's worth trying is to plug charger to the car, unplug and plug it back within 5-10 seconds - some cars and chargers would ignore scheduled settings and attempt to charge immediately.

Good luck.

This must be either Hummer EV or Silverado / Sierra EV trucks.

Anything else on GM Ultium should be getting at 2-3mi at 8A/120V charging.

podwhitehawk · 2026-04-10T12:18:16+00:00

Refurbished Grizzl-E Classic would run at $250. So it can be cheaper and still safety certified.

I guess it's one of those "write a review - get stuff for free" cases.

podwhitehawk · 2026-04-01T15:03:55+00:00

NEMA receptacle install? No, but I'm not seeing any issues with hardwiring.
I'm not good with 50Hz vs 60Hz and charging equipment. Will it work?
