LG P37 is identified in the supplied specifications as a 3.7 V, 37 Ah rechargeable NCM pouch cell with approximately 136.9 Wh of calculated nominal energy. The listed body dimensions are 8.2 × 140 × 270 mm, with an overall length of 311 mm. MisenBattery supplies cells and supports custom battery pack integration. These user-provided specifications require manufacturer verification before final electrical, thermal and mechanical design.
The supplied specifications list a nominal voltage of 3.7 V and capacity of 37 Ah, giving approximately 136.9 Wh of calculated single-cell energy. These figures support preliminary series and parallel configuration planning. Usable pack energy depends on the load profile, operating temperature, voltage window and system losses.
A maximum discharge rate of 5C is listed, corresponding to a calculated 185 A on the 37 Ah nominal capacity basis. The supplied data does not define whether this is continuous or pulse discharge. Confirm the permitted duration, SOC range, cooling requirements and temperature limits before setting pack current limits.
The supplied maximum charge voltage is 4.20 V, and the discharge cut-off voltage is 2.75 V. These values provide references for charger selection and BMS configuration. Charging current and any temperature-dependent voltage limits remain unconfirmed; establish complete operating requirements before validating the charger and protection settings.
The reported internal resistance is approximately 0.8 mΩ. The supplied table does not identify an AC or DC method, measurement frequency, SOC or temperature. Confirm the test method and batch measurements before comparing cells or applying this value to voltage-drop calculations, thermal estimates or cell-matching criteria.
The cell body measures 8.2 × 140 × 270 mm in thickness, width and length, while the listed overall length is 311 mm. Keeping these dimensions separate helps with preliminary enclosure planning. Confirm tab geometry, dimensional tolerances and manufacturer requirements for mechanical support before finalizing the pack layout.
The supplied charging temperature range is 0°C to 45°C, and the discharging range is −20°C to 60°C. These are operating temperature references, not confirmation that the maximum current is permitted across each entire range. Confirm temperature-dependent current limits and implement suitable sensing and thermal control in the pack.
Custom battery pack applications: MisenBattery supplies cells and supports custom pack evaluation for industrial equipment and mobility applications, subject to confirmed specifications and application testing. Integration should include a compatible BMS, fuse protection, voltage and temperature sensing, validated tab interconnects, insulation, cell spacing and appropriate thermal and mechanical design. Applicable CE, UN38.3, RoHS and UL documentation must be checked for the specific cell, pack and shipment; certification status is not established by the supplied data.
