4S 3000mAh, a new in-house pack

The BOOMFPV（炸机大叔） 4S long-range battery has a labeled capacity of 3000mAh, built with EVE 18650 cells, weighing 195g with an XT30 main connector and a 5-pin balance lead. Continuous 10C is a supplied figure, not an independent test.

Easy cruising and new-pilot practice

This pack is meant for easy cruising and new-pilot practice on 2.5 or 3 inch quads. It is on the heavy side. Before you install it, check all-up weight, center of gravity, the battery bay or mounting point, and the connector. It is not sold as a lightweight pack or for aggressive flying. A user has reported more than 15 minutes of flight on a Z25; actual flight time varies with the setup, all-up weight, conditions, and how you fly. That report is not an independent measurement or a flight-time guarantee.

Voltage and charging

16.8V fully charged, and a 2.8V per-cell discharge floor, are provided and label information. 2.8V is a lower limit, not an everyday discharge target. Land and recharge in good time. Avoid over-charge, over-discharge, and leaving the pack at a low state of charge. Use a matching 4S balance charger, and check the settings against the actual cells, the aircraft, and the pack.
