2016-2020 TESLA MODEL X S 75 Battery Module 5.35 kWh

**Tesla Gen 2 Battery Module (1071955-00-A) – For Solar / Powerwall / Storage! – With TBMM Photos** **Description:** ✅ **Module Specifications & Compatibility** - **Tesla Part Number:** **1071955-00-A** (Also seen as a **FLEX HCL-CELL** Gen 2 module). - **Nominal Voltage:** 24V DC (often listed as 21.9V or 22.8V). - **Energy Capacity:** 5.3 kWh (when new). - **Weight:** 55 lbs (25 kg). - **Original Application:** Used in **2016-2020 Tesla Model S and Model X** vehicles, typically those with the **75 kWh** pack configuration. - **TSN (Module Serial Number):** **1816506835** ⚠️ **Why I Am Selling (Please Read!)** I recently purchased these modules locally for my personal project, but I discovered they are the **newer Gen 2 design (1071955-00-A)**, which is **incompatible** with my older 2012 Model S High Voltage (HV) pack, which uses the Gen 1 modules (1009312-00-D/E). I am simply reselling this module immediately to recoup my investment. **This module was NOT pulled from my vehicle.** It is being sold by me, a private seller, after a compatibility mismatch error. 📸 **Condition and Testing** - **Condition:** Used. Physically sound with normal wear and tear from previous EV service life. - **Functionality:** The module is guaranteed to power on and hold a charge. - **Included Photos:** I have included photos from the **Tesla Battery Module Monitor (TBMM)** tool, which show good, stable voltage and cell values at the time of my testing. _Please examine these photos closely to verify the current state of charge and cell balance for your application._ See attached photos for proof that the BMS board is functional and that all cell voltage sense wires are operational. You can see each of the 6 brick voltages on the photo along with the 2 temperature sensor readings. Only 3mV difference! I also have included closeups of the BMS circuit board so you can see that model number. Tests were performed with a Tesla Battery Module Monitor (TBMM) is a diagnostic tool that connects to individual Tesla battery modules to quickly assess their health by checking voltage, temperature, and communication status. It is powered via USB-C and connects to the battery module's BMS port, providing instant feedback with a green "good" or red "bad" indicator and a web interface to view detailed information. This tool is useful for diagnosing issues without fully disassembling the battery pack, identifying imbalances between cell groups, and assessing used modules before purchase. Ignore the "20.3V" on the plastic covers - that's from the previous seller.   The TBMM voltages values were taken by me and are accurate as of October 13th when i took the photos. Module will be shipped in a custom plywood crate. 💡 **Ideal Use Cases** This module is perfect for: - **Off-Grid Power Systems / Solar Storage** - **DIY Powerwall Projects** - **Electric Vehicle Conversions** - **Replacing a failed module in a compatible Model S/X 75 kWh battery pack** (Please confirm the part number with your mechanic/technician). Shipping: Due to the weight and nature of the product, the module will be shipped via freight or securely boxed (approx. 55-60 lbs total package weight). SOLD AS IS: Due to the high-voltage nature of the component, no returns or warranties are offered.
