How to Choose Ovonic LiPo 2-Packs for RC Cars and FPV
Choose an Ovonic LiPo 2-pack by matching cell count to your model, then checking weight, size, and plug. The 2S pack weighs 118 g, the 3S pack weighs 176 g, and the 4S pack weighs 184 g. All three use XT60 plugs, and the 2S pack also includes a TRA plug. Prices cover two packs in each listing.
Quick facts
| Fact | Value |
|---|---|
| 2S pack | 2200mAh, 50C, 7.4 V, 16.28 Wh, 118 g |
| 3S pack | 2200mAh, 50C, 11.1 V, 24.42 Wh, 176 g |
| 4S pack | 1550mAh, 100C, 14.8 V, 22.94 Wh, 184 g |
| Discharge plugs | XT60 on all three, TRA added on 2S |
| Balance plugs | JST-XHR-3P, 4P, and 5P |
| Charge guidance | Stop at 4.2 V per cell |
| Pack quantity | 2 packs per listing |
How do the three cell counts compare?
The 2S pack runs at 7.4 V and the 3S pack at 11.1 V.
The 4S pack runs at 14.8 V, so the cell count sets the voltage.
The 2S and 3S packs both hold 2200mAh, while the 4S pack holds 1550mAh at a higher voltage.
Energy per pack runs 16.28 Wh for 2S, 24.42 Wh for 3S, and 22.94 Wh for 4S, as the listings state.
Weights run 118 g, 176 g, and 184 g, so the step from 2S to 3S adds 58 g on the model.
Which plug does each pack use?
All three packs use an XT60 discharge plug, so one lead type covers the set.
The 2S pack also includes a TRA plug, so it fits RC cars and trucks with either connector.
Balance plugs step with cell count: JST-XHR-3P on 2S, JST-XHR-4P on 3S, and JST-XHR-5P on 4S.
The 3S and 4S packs use 12AWG leads, and the 2S pack uses solid copper wire, as the listings state.
What does the C rating change?
The C rating times the capacity gives the rated continuous current, so the math is direct.
A 50C rating on a 2.2 Ah pack gives 110 A, which covers the 2S and 3S packs.
A 100C rating on a 1.55 Ah pack gives 155 A, which covers the 4S pack for FPV quads and airplanes.
Stop charging when any cell reaches 4.2 V, as the 2S listing states, and never charge unattended.
