🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Keep your WLtoys drone in the air with this 603048 3.7V 730mAh 1S Li-Po replacement battery. The WLtoys V686 series (including V636, V656, V686, and V686G) are popular entry-level camera drones known for their 720P live video transmission and stable flight characteristics. After repeated charge cycles, original batteries lose capacity — drastically reducing flight time from 8 minutes down to 3-4 minutes or causing the drone to struggle with altitude hold. This replacement battery restores the full 730mAh capacity, giving you back the original 8 minutes of flight time per charge. Features a standard JST connector for plug-and-play compatibility with your existing drone and charger. Built-in multi-layer safety protection guards against overcharge, over-discharge, and short circuits. Made with grade A cells. CE, RoHS, and UN38.3 certified.
Why Battery Quality Matters for RC Drones — More Than Just Flight Time: For WLtoys V686 series drones, a healthy battery isn’t just about longer flights — it directly affects drone performance. A degraded battery can cause: shorter flight time (the most obvious sign), reduced power output (drone struggles to climb or maintain altitude), unexpected low-voltage cutoff (drone drops from the sky even when indicator shows charge), slower response to control inputs, and camera instability during recording. This 603048 Li-Po replacement battery restores the full 3.7V nominal voltage and 730mAh capacity that your V686G, V656, or V636 was designed for. The 603048 designation refers to the battery’s dimensions: approximately 6.0mm thickness, 30mm width, and 48mm length — a standard size for many small quadcopters. Always allow the battery to cool down before recharging, store at approximately 50% charge (3.8V) when not flying for weeks, and never leave Li-Po batteries charging unattended. For WLtoys V686G users who enjoy the 720P camera feature, a fresh battery ensures stable voltage for clear video transmission without dropouts.
Compatibility Note: Designed for WLtoys V636, V656, V686, V686G, V686K and JJRC V686 RC drones. Please confirm your drone uses a JST connector and that the battery compartment measures approximately 58 × 33.5 × 12mm before purchasing. Charging time is approximately 90 minutes using a compatible 1S Li-Po balance charger. We recommend purchasing multiple batteries for extended flying sessions — swap and keep flying while the depleted battery cools down and recharges.

Frequently Asked Questions

This 603048 3.7V 730mAh Li-Po battery with JST connector is compatible with WLtoys V636, V656, V686, V686G, V686K and JJRC V686 RC drones. The WLtoys V686G features a 720P camera with live video transmission to your phone. For WLtoys V686G battery replacement, this 730mAh 1S Li-Po battery is the exact match. Before purchasing, please check that your drone uses a JST connector (the standard white 2-pin plug) and that the battery compartment measures approximately 58mm × 33.5mm × 12mm. This battery is NOT compatible with WLtoys V911, V912, V913 helicopters, V666, V686 upgrade versions with different connector types, or other brands that use different battery sizes or connectors (such as Walkera, Syma, Hubsan). If your drone uses a different connector, you may need an adapter or a different battery.

This 730mAh 1S Li-Po battery for WLtoys V686 series provides approximately 8 minutes of flight time for WLtoys V686, V656, and V636 drones under normal flying conditions. Actual WLtoys V686 flight time depends on several factors: flying style (aggressive vs. gentle), wind conditions (more power required in wind), camera usage (the V686G's 720P camera draws extra power), and battery age (a fresh battery delivers full 730mAh capacity). With the camera enabled on the V686G, expect 6-7 minutes of flight time. Charging time is approximately 90 minutes using a compatible 1S Li-Po balance charger set to the correct 4.2V charge limit. For extended flying sessions, we recommend purchasing multiple batteries — you can swap in a fresh battery while the depleted one cools down and recharges. Never recharge a Li-Po battery while it's still hot from flying; allow it to cool to room temperature first for safety and longer battery life. A typical WLtoys V686 battery charger indicator will show red while charging and turn green or off when complete.

Li-Po batteries require proper care for safety and longevity. For WLtoys V686 Li-Po battery safety: 1) Always use a compatible 1S Li-Po balance charger — never use a non-balance charger or a charger designed for other battery types. 2) Never leave charging unattended — Li-Po fires are rare but serious. Charge on a non-flammable surface. 3) Avoid full discharge — land your drone before the battery drops below 3.0V per cell (when you notice the drone struggling to maintain altitude). Keeping charge above 20% extends battery life significantly. 4) Cool down before recharging — a hot battery fresh from flying should rest for 10-15 minutes until cool to the touch. 5) Store at approximately 50% charge (3.8V) when not flying for more than a week — do not store fully charged or fully depleted. 6) If the battery becomes swollen, puffy, or damaged, stop use immediately and dispose of properly at an electronics recycling center — do not throw in household trash. 7) For 603048 Li-Po battery care during storage, keep in a cool, dry place away from direct sunlight. Following these guidelines will maximize the number of charge cycles you get from this 730mAh replacement battery for WLtoys V636 and V686 drones.
