Overview
Choose a replacement for a micro helicopter, quadcopter or model airplane that uses 1S batteries. Each pack has a flat pouch cell, a protection board and a two-wire lead. Match the model code on your existing pack, then select the connector with the same housing and wire positions.
Features
- The protection board sits at the end of the pouch. A protection IC and MOSFET switching stage guard against short circuits, excess current, overcharge and overdischarge.
- The compact lead runs alongside the pouch. Leave space for the connector and wire bend as well as the measured cell body.
- Two packs with the same capacity can have very different shapes. For example, the 500 mAh 802035 is shorter and wider than the 500 mAh 851740.
Specifications
- Cell configuration: single-cell rechargeable lithium-polymer (1S)
- Nominal voltage: 3.7 V
- Discharge marking: 25C
- Capacity range: 85–1300 mAh
- Connector orientation: standard polarity as shown in the plug guide. Connector availability depends on the battery model.

What's Included
One battery with the selected pack model, capacity and installed connector.
Applications
For aircraft designed for a single 3.7 V pack within the listed dimensions and the aircraft's allowable battery weight. A higher-capacity pack adds size or weight and can reduce flight time if the aircraft is overloaded.
FAQ
How do I check the plug polarity?
Turn the plug so its metal contacts face up, as in the guide below. Compare the wire on the left with your original battery. The red JST example has the black wire on the left; the other five examples have red on the left.
Will either 500 mAh pack fit the same compartment?
Check the dimensions. The 802035 measures 38 × 20 × 8 mm. The 851740 measures 43 × 18 × 9 mm across the cell and reaches 20 mm across the wrapped end.
