Just getting started. Cells are mapped and discharge jig is draining the unwanted bricks. 2 in this case as it needs 5 bricks removed from the middle. My last Tesla3 module and it’s sold. These make great Gem batteries and I’m hoping someone will pick up the torch. ![20210619_080658](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/a/ab499a98375abf641f1251723c98e8e189d80371.jpeg) ![20210619_080643](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/b/b96c0a889f5bbb156ac60339b8e3ec2c7aa2e283.jpeg) ---

Well I think I am going to have to pick up the torch… I have a 25S in my garage that we will need to split eventually. Sooner than later actually. Glad I will have a good teacher 🙂 ---

@smspring There’s the perfect battery for your 2016! There’s a shipment coming from MN to San Diego the end of July if you want to piggy-back on that. ---

I gave @smspring the lead batteries out of my 2016 and that got him back up and running for the near term. I think he still wants to go tesla. Let me nudge him out-of-band. ---

@Inwo @Erniea15 i still want them and the other parts you can supply. But I don’t need them urgently so if you know you will make more in the next couple months then I am Ok with waiting. Up to you but I am ready to pay as soon as they are shipping. ---

I will not be making another Tesla battery, but I have a good supply of new batteries. ![image](https://canada1.discourse-cdn.com/flex030/uploads/electricforum/original/2X/4/4368e98708f6a9d27cfc4bfb01264cd178e96c84.jpeg) ---

@Erniea15 @Inwo I would still like the Tesla and other parts. Could I give you a deposit while we wait on the shipper? I believe the shipper will be in San Diego On the 24th for Ernie’s older gem. ---

Yes, send some money and I’ll get it ready for him. Battery Motor Harness Controller DCI delta-q charger? If you go all in with Ernie, that’s some serious investment. 🙂 > **[Pay David Bissen using PayPal.Me](https://www.paypal.com/paypalme/INWO?locale.x=en_US)** > > Go to paypal.me/INWO and type in the amount.

@Erniea15 @smspring I have the motor drilled. For a new Gem correct? Ernie should have all his parts and can give me a list of what to get ready. George had email trouble but is responding now. ---

- 8kw motor (drilled if you’ve got it) - new sevcon s4 72 volt controller programmed for 48v contactor - deltaq charger - telsa 20s battery, in case, jk BMS - wiring harness for the accelerator and directional control He has a 2016 just like mine. Previous owner changed the gears so it does 30mph now… guess those are the 12:1 gears. That should make it almost identical to mine. So once I get around to doing mine, should have it all figured out to help Steve ---

I eventually want to explore the super charger option… But I’ll worry about that later when I’m up and running. Trying to think of there’s anything else I should buy while George is coming out this way! I have a stock pile of motors. Need to find more cars to put them in 😉 ---

Tnx, that helps a lot. I got two motors drilled today. Can’t test fit them yet but working on it. He just sent some money, so I can get it all ready to go. The JK bms is a different one I’m using now. The two Tesla batteries have “ant” bms with lcd. Have you looked at yours lately to see if it has a high or low cell? The one I have here, #3 is always a little low, even if I charge it. After this module was in storage for more than a year cell was only down .2 volts, so not a big issue. I disconnected the bms/lcd to see if that’s doing it. ---

This may be a stupid question[,](https://www.avxperten.dk/toastmaskiner/) but should i at all be concerned about the legality of messing with batteries for EV’s? Is there a sort of “do’s and dont’s” list that anyone could share? 🙂 Thanks in advance. [Next page](https://community.electricforum.com/t/tesla3-20s-build/21699.md?page=2)
