M & L for De-commissioning old unsv batteries and Supply installation testing and commissioning of Installation & Mechanical Setup (Replacement)This phase covers the physical placement and structural handling of the new hardware based on the manufacturer's physical specifications. Battery Inspection & Unpacking: Unpack the 30 new 12V DC nominal voltage, 42 AH batteries. Verify that all terminals are the required F6 / Brass with lead coating type and free of defects. Flexible Orientation Positioning: Position the 30 new batteries into the existing rack or housing. Because these batteries utilize AGM (Absorbent Glass Mat) technology, they can be safely installed in any required orientation (vertical, horizontal, or sideways) without risk of electrolyte leakage. Series String Configuration: Mechanically link the 30 batteries in series to achieve the required cumulative DC voltage compatible with the existing Mystique & Joint Securing: Tighten all terminal connections securely to handle the high Short Circuit Current capability of 922 Amps and minimize contact resistance (matching the internal resistance specification of 8 mΩ fully charged @ 27°C).Part 3: Electrical Integration & Commissioning (SMPS Tuning)This final phase involves configuring the charging infrastructure to match the exact chemical and thermal operational requirements of the new AGM batteries to maximize their 2–3 year service life. Job for SMPS Charger Voltage Configuration:

Program the parameters of the existing SMPS to align with the mandatory AGM charging profiles: Float Voltage: Set precisely to 13.5V per module (totaling 13.5{V} X 30 = 405V DCfor the string).Boost/Cycle Voltage: Set to 13.8V per module (totaling 13.8V x 30 = 414V DC for the string).Current Limiting: Adjust the SMPS maximum charging current limit so it does not exceed 25% of the rated capacity (strictly capped at 10.5 Amps max) to avoid thermal runaway. Thermal Compensation Calibration: Connect and configure the SMPS temperature sensors to apply a compensation factor between -18mV to -20mV / °C to protect the cells during shifts within their 0°C to 45°C operating range.Testing & Logging: Measure the total open-circuit voltage of the series bank, initiate a baseline charging cycle from the SMPS, and log the initial internal resistance values to track the 3% monthly self-discharge rate baseline.
