Thanks for the feedback. Will charge them until ~4.00v.

Re: VW eGolf hardware
Friends, Do you guys know what is the correct voltage for those lithium polymer cells from the golf gte? Ive read that they are Lithium nickel manganese cobalt (NMC). And from what i've found they have a 3.7 V nominal voltage with a 4.2 V maximum while charging. The same as 18650. This is correct? T...

Re: VW eGolf hardware
I'm no expert in ebike BMS's so can't give proper advice but I've used a couple of cheap units from China and had no issues. You could even try an active balancer to share the voltage across the pack rather than a passive BMS that just takes power from the highest cell. Have a look through this thr...

Re: VW eGolf hardware
Sorry if I'm missing something here but for 14S couldn't you use an ebike BMS? The ANT BMS's are pretty good and allow you to monitor the pack via a mobile phone. Vorteck's VBMS software is only £10 and works great. Thanks for the help! Yeah, i was thinking about using some external BMS. I was look...

Re: VW eGolf hardware
Nice to know. Thanks.
Can you post some photos of your work? I'm thinking to do the same with my cells.

Re: VW eGolf hardware
I am developing a similar modular board with cheaper ESP32 chip. You may try to contribute by porting Teenys code to ESP32. https://openinverter.org/forum/viewtopic.php?t=2256 I have some experience with Arduino. Will take a look on this topic and do my best to help. I was reading on another forum ...

Re: VW eGolf hardware
You could use modules in parallel and with BMS connected just by CAN bus. Use SimpBMS and wire your harness from the GTE wires. But i use those cells in my sola array with JK BMS wired for 12S. Problem is not with BMS. Inverter requires minimum 48V to return back to battery, which is to much for 12...

Re: VW eGolf hardware
Hi friends, Just got one complete Golf GTE hybrid battery. Each module (it does have 4 modules) uses 2x 12s lithium cells connected in series, as already said on this topic. My offgrid solar system works on 14s, but the VW GT batteries are 12s. It is possible, in any way, to use the battery pack wit...

Re: Grid Tie Inverters - What's the difference?
I have some of those bad boys connected to the output of my 5kVA 48v low frequency inverter. They feed the inverter AC Output and allow me to run bigger things like my 24kBTU A/C unit with my entire home.
Just changed the fans on them, the default one sucks.
