U1 vs U1R Battery: Understanding the Key Differences
The primary difference between a U1 battery and a U1R battery lies in their sizes and compatibility. A U1 battery is a standard size that is commonly used for lawn and garden equipment, while a U1R battery is a slightly smaller and more compact version of the U1, designed to fit in tight spaces in certain applications.
Single battery for two motors
1. One large battery connected to both motors. ESCs in the fuselage near the battery and lots of motor wires running out to the wings. 2. One large battery connected to two ESCs in the wings. Fewer wires, so less weight. But probably should put capacitor bank at each ESC. 3., 4. As above but with two battery packs connected in parallel.
