1S LiPo Batteries

This category covers single-cell (1S) lithium polymer batteries, the primary power source for the smallest FPV drones, especially popular TinyWhoops. They come in two main voltage variants:

• Standard 1S LiPo: Nominal voltage 3.7V, charged to 4.20V.
• 1S LiHV (High Voltage): Nominal voltage 3.8V or 3.85V, charged to a higher voltage of 4.35V. They offer slightly more energy and "punch", but require a charger that supports LiHV mode.

1S batteries are ideal for:

• TinyWhoop class drones: Small drones (65mm-75mm) mainly intended for indoor flying.
• Ultralight Micro FPV builds: Where every gram of all-up weight matters.
• FPV fun and learning: Safe and easy to handle, great for beginners.

They feature small capacities (usually from 250mAh to 650mAh) and specific connectors like PH2.0 or BT2.0. We stock 1S packs (both LiPo and LiHV) from proven brands like GensAce/Tattu or BetaFPV.

When choosing a 1S battery for your micro drone, consider these key aspects:

• Cell Type (LiPo vs LiHV): Decide if you prefer standard LiPo (charged to 4.20V) or LiHV (charged to 4.35V). LiHV might offer a slight edge in power/flight time but requires a charger with LiHV mode. Also, check if your drone's components (especially FC/ESC) are safe with 4.35V.
• Capacity (mAh): Higher capacity means longer flight time, but also more weight, which greatly impacts agility in the micro class. Find a balance (e.g., 300mAh for a light 65mm Whoop, 450-550mAh for a 75mm).
• Discharge Rate (C rating): Small Whoop motors can be power-hungry. A higher C rating (e.g., 75C or more) will provide more stable voltage and better "punch".
• Connector: This is very important! Check which connector your drone requires – the most popular are PH2.0 and the newer, more efficient BT2.0. Choose a battery with a matching connector.
• Weight and Dimensions: Ensure the battery fits the drone's holder and doesn't upset its balance.

Testing different capacities, cell types (LiPo/LiHV), and brands will help you find the ideal 1S pack for your flying style.

Safety when handling LiPo batteries is absolutely paramount! Improper handling poses a real fire risk. Always follow these rules:

• Charging: ALWAYS use a microprocessor charger designed for LiPo with balancing function (even for 1S, using dedicated chargers is recommended). NEVER leave charging batteries unattended. Charge in a fire-resistant location (e.g., in a LiPo Safe bag, on a ceramic/metal surface). Never charge damaged, puffed, or deformed packs. Use correct charger settings (cell count=1, LiPo/LiHV type). Recommended charge rate is 1C unless the battery manufacturer explicitly allows higher.
• Usage: Avoid over-discharging cells (generally don't go below 3.3V under load, resting voltage ~3.7V for LiPo, slightly higher for LiHV). Monitor battery voltage in OSD or with a timer. Land when voltage is low. Protect batteries from physical damage and punctures.
• Storage: For longer storage (several days or more), charge/discharge LiPos to storage voltage - approx. 3.80-3.85V. Use the 'Storage' function on your charger or charge to this level. Store in a cool, dry place, ideally in a special LiPo Safe bag or ammo can. Do not store fully charged or fully discharged for long periods.
• Disposal: Never throw LiPos in regular trash! Discharge them fully (e.g., using a light bulb or charger's discharge function to a low voltage) and take them to a designated battery recycling facility.
