แบตเตอรี่ BP37X370 (3.7V 370mA) _280X RX

Swapped out the old battery in my receiver and it clicked right in, no fiddling needed. Getting a full day of hunting out of a single charge again, which is exactly what I needed from a 370mAh replacement.

Battery life is back to lasting through a full day of training, which is a relief. Only gripe is that it took a bit longer to charge the first time than I expected.

Dropped right into the receiver with no fitting issues, and charging it back up is quick. Only gripe is I wish the 370mAh gave me a bit more runtime on long training days, but for regular sessions it's been solid.
