FPV Battery Chargers for LiPo, Li-ion & LiHV Batteries
FPV battery chargers are used to charge and maintain LiPo, Li-ion and LiHV batteries for racing drones, freestyle drones, cinewhoops and DIY FPV builds. Choose a charger based on battery type, cell count, charge current, input power, connector support and whether balance charging or storage mode is required.
How to Choose an FPV Battery Charger
Choosing an FPV battery charger is mostly about matching your real flying setup. Start with the batteries you already use, then check whether the charger can handle the right chemistry, cell count, connector and charging power. Use the steps below to narrow down the right option faster.

Step 1: Match the Battery Type
First, check the battery label. If you fly standard FPV packs, you likely need a LiPo battery charger. If your packs are marked LiHV, choose a charger with LiHV mode. For Li-ion or 18650 cells, make sure the charger clearly supports lithium-ion charging. Do not assume every FPV charger supports every lithium battery type.
Step 2: Check the Cell Count
Next, match the charger to your battery cell count. Whoops and micro drones usually use 1S batteries. Many freestyle and racing drones use 4S or 6S packs. If you fly different builds, a charger that supports 1S-6S gives you more flexibility.
Step 3: Choose Enough Charging Power
A small 1S charger is fine for tiny whoop packs, but it will not be practical for larger 4S or 6S batteries. If you charge several packs before each session, choose a charger with higher wattage or dual-channel charging. More power does not always mean better, but too little power means longer waiting time.
Step 4: Confirm the Connector and Balance Port
Before buying, check the connector on your battery, such as XT30, XT60, PH2.0 or BT2.0. For 2S and higher LiPo or LiHV packs, you also need balance charging support. A balancing LiPo battery charger helps keep each cell at a similar voltage during charging.
Step 5: Decide Where You Charge Most Often
If you mostly charge at home, an AC/DC smart charger is simple and convenient. If you charge at the flying field, a DC charger with an external power source can be faster and more flexible. Pilots who charge many packs in one session may prefer a dual-channel or multi-port charger.
FPV Battery Charger Comparison
| Charger Type | Best For | Key Checks Before Buying |
|---|---|---|
| 1S Charger | Whoops, micro drones and small FPV batteries | Connector type, LiPo/LiHV support, number of ports |
| Balance Charger | 2S-6S LiPo and LiHV FPV drone batteries | Cell count range, balance port, charge current, power output |
| AC/DC Smart Charger | Home charging and beginner-friendly setups | Supported battery types, plug type, max watts, storage mode |
| DC Charger | Field charging and higher-power FPV battery setups | External power supply, input voltage, max current, connector support |
| 18650 Charger | Li-ion cells used in FPV gear, long-range packs or field systems | Cell size support, Li-ion compatibility, charging current |
FPV Battery Charger FAQ
Q: Can one charger charge LiPo, Li-ion and LiHV batteries?
A: Some smart chargers support LiPo, Li-ion and LiHV batteries, but not every charger supports all three. Always choose the correct battery mode on the charger before charging, because each chemistry uses different voltage settings.
Q: What is a balancing LiPo battery charger?
A: A balancing LiPo battery charger monitors the voltage of each cell in a multi-cell battery pack. This helps keep the cells even during charging and is recommended for most 2S, 4S, 6S and higher FPV drone batteries.
Q: Is a 18650 battery charger the same as an FPV LiPo charger?
A: No. An 18650 battery charger is usually designed for cylindrical Li-ion cells, while an FPV LiPo charger is designed for multi-cell LiPo or LiHV drone battery packs. Some advanced chargers support multiple battery types, but compatibility should be checked before use.
Q: What does storage mode do on a battery charger?
A: Storage mode brings a battery to a voltage level that is better for short-term or long-term storage. It is useful when FPV batteries will not be used for several days or longer.
Q: How much charging power do I need?
A: Charging power depends on battery voltage, capacity and charge current. Small 1S batteries need very little power, while 4S and 6S packs require more. If you charge multiple batteries or use parallel charging, choose a charger with higher wattage.
