Tattu R-Line Version 4.0 4S 850mAh 130C LiPo Battery XT60

The Tattu R-Line Version 4.0 850mAh is a 4S racing LiPo built for punch and low sag, aimed at 3-inch racers and light 4S freestyle builds. Version 4.0 brings lower internal resistance and less weight than earlier R-Line packs, and the XT60 lead suits frames and stacks wired for full-size plugs.

Use it on 4S-rated or 3–6S flight stacks; it is too much voltage for 2–3S-only boards. Many 3-inch frames and AIO boards ship with XT30 leads, so swap the lead or fit an adapter first. Charge in standard LiPo mode at 4.2 V per cell, not LiHV, and store at 3.8 V per cell.
