Description
LiPo Rechargeable Battery 4000 mAh, 7.6 V, 2S — BOLTON SKU 53908.
About the LiPo Rechargeable Battery 4000 mAh 7.6
This battery lipo rechargeable 4000 mah pack is a two-cell lithium-polymer assembly with a nominal terminal voltage of 7.6 V. The 2S designation means two cells connected in series, and dividing the pack voltage by the cell count gives 3.8 V per cell — the nominal figure for high-voltage lithium-polymer chemistry rather than the 3.7 V of a conventional LiPo cell. That distinction matters in service, because a high-voltage pack has a higher fully charged voltage per cell than a standard LiPo and requires a charger set to the correct chemistry; charging it on a standard LiPo profile will not fill it, and the reverse error is hazardous. At 4.0 Ah and 7.6 V the pack stores approximately 30 Wh of energy. Lithium-polymer cells are subject to dangerous-goods rules in transport and require balance charging, temperature-controlled storage and storage at a partial state of charge.

Typical applications
A 2S 7.6 V pack at 4000 mAh is a payload and avionics power source rather than a main propulsion pack: powering ground-control and radio equipment, camera and gimbal payloads, handheld and portable instruments, small UAS airframes and test rigs. The high-voltage 3.8 V per cell chemistry is chosen where slightly more usable energy and a higher working voltage are wanted from the same physical two-cell footprint.
