Beskrivelse

Case for Heltek V3 Fits Heltec V3 with soldered pins ! Requires: 4x M2x10mm screws and 4x M2 brass heat-set inserts. Battery: Designed for a 21700 battery. For an 18650 battery, you must add a soft spacer (gasket). BMS Required: You must use a battery protection board (BMS). Heltec does not have deep discharge protection and will drain the battery below 2V, damaging it. Buttons: Use transparent plastic for the buttons so the LED light can shine through. Charging: The built-in Heltec charge current is only 150–200mA. The battery will charge very slowly. Power Consumption: ESP32-S3: ~120mA (idle) or ~30–50mA with optimized firmware. SX1262 (LoRa): ~5mA (idle/RX) and up to 140mA @ 22dBm during packet transmission (lasts less than a second). Future Upgrade: A future case version may include an external charging board with a BMS (like a TP4056 module). There is already some free space inside for this.
