Key Benefits of LiPo Batteries for RC Models:
1. High energy density: More power in a compact, lightweight pack for longer runtime without extra weight.
2. Lightweight design: Keeps aircraft nimble and surface models responsive, ideal for flight performance.
3. High discharge rates (C-rating): Strong current output for hard launches, sharp turns, racing, and 3D maneuvers.
4. Longer run times: Higher capacities (mAh) mean more drive or flight time between charges.
5. No memory effect: Unlike NiCd, you can top up anytime without losing capacity.
6. Faster charging: With the right CC/CV charger, LiPos get you back on track or in the air sooner.
7. Consistent power: Flatter discharge curve provides steady performance until the pack is nearly empty.
8. Lower self-discharge: Holds charge better in storage than many older chemistries.
9. Flexible setups: Common voltages include 2S (7.4V), 3S (11.1V), 4S (14.8V), and 6S (22.2V) to match your motor/ESC.
10. Versatile connectors: Widely used plugs like XT30, XT60, XT90, EC3/EC5, Deans/T-plug, JST make integration easy.

LiPo vs. NiMH / NiCd (Quick Comparison):
Compared with NiMH (Nickel-Metal Hydride) or NiCd (Nickel-Cadmium) batteries, LiPos offer a better power-to-weight ratio, faster charging, and stronger burst output – key advantages for high-performance RC use.

Choosing the Right LiPo:
1. Voltage (S-count): Match 2S/3S/4S/6S to your ESC and motor specifications.
2. Capacity (mAh): Higher mAh = longer runtime but more weight.
3. C-rating: Max continuous current ≈ Capacity (Ah) × C. Example: 2200 mAh (2.2 Ah) × 35C ≈ 77 A.
4. Connector type: Use a plug compatible with your model and charger (e.g., XT60).

Basic Care & Safety Tips:
1. Charge only with a compatible LiPo balance charger (CC/CV); never charge unattended.
2. Observe polarity (red = + / black = −) and avoid short circuits or damaged leads.
3. Let packs cool before recharging; operate within recommended temperature limits.
4. For storage, set to ~3.75–3.85V per cell and store in a fire-retardant LiPo bag.
5. Stop using any pack that is swollen, punctured, or leaking.

In short, LiPo batteries deliver the light weight, high power, fast charging, and consistent output that keep RC models fast, responsive, and ready for action—making them the best choice for most RC applications in the U.S. market.

mAh (milliamp-hour) refers to your battery’s storage capacity — the amount of energy it can hold. A higher mAh rating means longer run time between charges, so if you’re looking to keep your RC car on the track or your drone in the air for extended sessions, opt for a higher capacity pack. Just remember, higher mAh usually adds weight, which can affect speed and handling.

Voltage (S count) tells you the battery’s power level, measured in series cells — for example, 2S (7.4V), 3S (11.1V), or 4S (14.8V). More voltage translates into faster acceleration, higher top speeds, and snappier throttle response. However, your ESC, motor, and electronics must be rated for the voltage you choose. Using too high a voltage can overheat or damage components. Always match the voltage to your RC setup for safe, reliable performance.

C rating measures how quickly a LiPo battery can deliver power under load. A higher C rating—like 35C compared to 20C—means faster acceleration, sharper throttle response, and better performance during aggressive maneuvers.

Burst rating is the short-term “turbo boost” your battery can provide for a few seconds when you need extra power—such as in tight corners, steep climbs, or full-speed sprints.

For high-performance RC models like racing drones, aerobatic planes, and competition cars, choose a battery with a higher C rating and solid burst capacity. This ensures your pack can deliver consistent, high-current output when it matters most, keeping your model fast, responsive, and race-ready.

Choosing the right battery doesn’t have to be overwhelming. Whether you want longer flight times, higher speed, or race-ready power, it’s all about finding the right balance of key specs:

• mAh (capacity): Higher mAh means longer runtime but more weight—balance capacity with your model’s performance needs.
• Voltage: More volts = more speed, but only if your motor and ESC can handle it. Check compatibility to avoid damage.
• C rating: For high-performance models like racing drones or 3D planes, a higher C rating ensures quick power delivery.
• Size & weight: Confirm the battery fits your model without upsetting balance or handling.

Every RC model is unique—always follow your manufacturer’s recommendations for the safest, most effective choice. We can suggest options, but the final decision depends on your setup and performance goals.

LiPo batteries require a special balance charger designed for their chemistry. This ensures each cell charges evenly, keeping the pack balanced for consistent performance and longer lifespan.

Using the wrong charger or setting can cause overcharging, uneven cells, overheating, or even fire. Always charge in LiPo mode to protect your battery and your equipment.

All our LiPos include a balance lead that lets the charger monitor and adjust each cell during charging. This safeguard keeps your battery healthy, delivering reliable power every time.

In short: the right charger + balanced charging = maximum safety, peak performance, and a battery that’s ready for action.

Keep around 50% charge: Store LiPos at ~3.7–3.85V per cell to avoid stressing the cells.
Store in a cool, dry place: Keep away from heat, sunlight, and humidity—ideal spots are drawers or shelves with stable temperatures.
Never drain completely: Stop use before voltage drops below ~3.0V per cell to prevent permanent damage.
Check periodically: For long-term storage, check every 1–2 months and adjust charge back to the 50% sweet spot if needed.
Proper storage keeps LiPo batteries safe, extends lifespan, and ensures they’re ready whenever you need them.

Overcharging = Trouble: Charging above ~4.2V per cell can cause swelling, instability, leaks, reduced capacity, or even fire. Always use a charger with voltage cut-off to stop at the safe limit.
Over-discharging = Permanent Damage: Dropping below ~3.0V per cell can irreversibly damage cells. Stop use before reaching the limit, and use a voltage checker if your device has no built-in monitoring.
Safety First: Both overcharging and over-discharging shorten lifespan and raise safety risks—swelling, leaks, or combustion.
Right Tools Only: Use a LiPo-compatible charger with cut-off and, when needed, a separate voltage checker to maintain safe operating ranges.
Avoid both extremes to keep your LiPos safe, long-lasting, and performing at their peak.

Avoid Overcharging: Charging beyond ~4.2V per cell stresses cells, causing swelling, leaks, or failure. Always use a LiPo charger with voltage cut-off for safe charging and longer battery life.
Never Over-Discharge: Dropping below ~3.0V per cell can cause irreversible damage. Stop use before reaching this limit, and use a voltage checker if your device lacks built-in monitoring.
Keep It Cool (Not Cold): Avoid extreme heat or cold—store and operate at moderate temperatures, away from direct sunlight, hot cars, or freezing areas to protect performance and lifespan.
Follow Storage Guidelines: Store at ~50% charge (around 3.7–3.85V per cell) in a cool, dry place to reduce cell stress and maintain health.
Use a Balance Charger: Ensures all cells charge evenly, preventing imbalance and extending battery life. Always balance charge to keep performance consistent.
Treating your LiPos right means more power, longer life, and fewer issues—keeping your RC gear ready for every flight, race, or adventure.
