Detailed Answer
Transmitter battery compartment design points: 1. Sealing (IP67 waterproof, independent sealed compartment + ePTFE breathable membrane to prevent condensation); 2. Reverse-polarity protection (no damage if batteries are inserted backwards); 3. Gold-plated contacts (anti-oxidation, reliable contact); 4. Spring-loaded design (batteries fixed, do not pop out on impact). Leader LD series battery compartment: AA compartment + optional Ni-MH/lithium; Xingjia comes standard with a lithium compartment. Make sure the seal ring is seated correctly when changing batteries.
