The BP-550 Battery Pack is designed to mount to Lab599 TX-500 series transceivers and provide power with replaceable 18650 Li-Ion batteries.
It supports charging via the USB Type-C port and can be powered from various DC sources with a voltage range of 13 to 50 V (such as consumer electronics power supplies, vehicle on-board networks, solar panels, etc.). The device features an LED indicator to show the remaining battery charge and the ability to display additional information on the transceiver screen.
The battery pack's body is made of impact-resistant plastic, and its power connectors, buttons, and LEDs are equipped with rubber seals to protect against splashes and dust. Folding legs provide a comfortable tilt and prevent accidental activation during transport. An aluminum heat sink ensures optimal temperature conditions for the transceiver with the battery pack installed.
Battery Requirements for BP550:
The BP550 is designed to operate with standard flat top, unprotected 18650 cells only. The standard dimensions of an 18650 cell are 18 mm in diameter and 65 mm in length — hence the designation “18650.” However, some variants of the 18650 cell are modified by the addition of a button top and/or an internal protection circuit. These modifications can increase the overall length of the cell from the standard 65 mm to 70 mm, or in some cases, even longer. Important:Do not use protected or button-top 18650 cells with the BP550, as they may not fit properly and could cause operational issues.
