What to Look for in a Dual Charger

Beyond the top picks reviewed, keep these factors in mind while choosing a dual battery charger for your RC needs:

Charge Rates and Power

The charge rate, specified in amps, indicates how quickly each charging port can charge. For example, a “5 amp” charger can charge at up to 5 amps per channel. Faster charge rates allow you to get going quicker.

Make sure to size appropriately – low capacity battery packs don’t need high amp chargers. But hungry high capacity packs require extra juice during charging sessions.

Dual chargers range from about 25W on the lower power end up to 200W+ for specialty high voltage packs used in extreme applications.

Supported Battery Chemistries

Ensure the charger works with all the battery types you need to charge:

  • LiPo – Lithium Polymer, the most popular modern battery chemistry
  • NiMH – Nickel Metal Hydride, an affordable chemistry used in many entry level RCs
  • NiCd – Nickel Cadmium, an older heavy chemistry being phased out
  • LiFe – Lithium Iron Phosphate, a stable chemistry growing in popularity
  • Pb – Lead Acid, used in some hobby grade RC cars

Ideally get a charger supporting the common LiPo at a minimum, with flexibility for other chemistries.

Balance Charging

Balance charging is essential for lithium batteries to ensure the cells all charge evenly for maximum performance, life and safety.

LiPo and LiFe packs require special connectors for balance charging. Ensure the charger is compatible with the balance leads on your packs.

Display Type

A backlit LCD provides the most detailed stats like battery voltage, current capacity, time remaining etc.

LED displays are simpler – different color codes indicate charge state and warnings. Ideal for beginners.

Safety Features

Lithium batteries require careful charging to avoid damage and fire risks if handled improperly. Look for:

  • Temperature monitoring and automatic shutdown
  • Voltage limits to prevent overcharging
  • Fire resistant casing
  • Internal fan to dissipate heat
  • Automatic cutoff when full to prevent overcharging

Advanced safety mechanisms provide essential protection and peace of mind.

Reputation and Reliability

Stick with established RC brands known for quality chargers. Ask fellow hobbyists for recommendations of models they’ve used reliably for years.

A reliable charger from a trusted brand goes a long way for safety and effective charging cycles.

Charge Rate Recommendations

Match your battery capacity needs to an appropriately specced charger:

Battery CapacityMax Charge Rate

500-3000mAh – Up to 5 amps

3000-5000mAh – 5-8 amps

5000-10000mAh – 8-10 amps

10000mAh+ – 10 amps+

Charging at 1C (battery capacity = charge amps) is ideal. Never charge at rates higher than the battery’s rated maximum charge current.

Using Your Dual Charger Safely

While modern RC chargers contain protections, always practice safe charging habits:

  • Never exceed the battery manufacturer’s recommended max charge rate
  • Keep batteries in a fireproof bag or container when charging
  • Avoid charging unattended – monitor periodically
  • Ensure room ventilation and avoid charging near flammables
  • Use the right charger settings and modes for your particular battery type
  • Stop use if batteries heat up or swell abnormally

With proper charger precautions and handling, you can safely charge batteries worry-free for hundreds of cycles.


A good dual battery charger saves time and provides convenience when charging multiple packs for RC applications. Models from trusted brands like Traxxas, Venom, and Hitec offer excellent performance and safety. Seek out balance charging, suitable power levels, intuitive displays, and support for your required battery chemistries. Used responsibly, a quality dual charger simplifies keeping your packs charged and ready for action.


Should I get a charger with more than 2 ports?

For most hobbyists, a dual 2-port charger provides ideal charging flexibility without unnecessary complexity. However power users with many battery packs may appreciate 4, 6, or even 8 port chargers to keep up with demand.

How long does an RC battery take to charge typically?

Charge times depend on the charger’s power level, battery type, and capacity. But roughly 1-3 hours is typical for full charges. Smaller batteries under 5000 mAh may fully charge in under an hour with faster chargers.

What should I look for in a portable field charger?

Key features for portable chargers are small footprint, lightweight construction, 12V DC capability to charge from a car battery, and an easy to read display when charging in daylight conditions.

Are all RC battery connectors compatible, or are there different types?

Pay close attention to connector styles – major types are Traxxas, EC3, XT60, Deans and others. Ensure your charger’s discharge leads match the battery connector style. Adapters can be purchased if not.

What should I do if my battery starts to puff up or swell while charging?

Immediately stop charging and discharge the battery outside or in a fireproof container. Never use or recharge a battery that has puffed or swollen – the gases indicate a damaged internal cell. Disconnect and properly dispose of it.

How can I tell if my RC battery charger is damaged or needs replacing?

Signs of damage include scorch marks on the casing, rattling internal fan, jiggling connector prongs, damage to cords, screen abnormalities, or if batteries are no longer charging fully despite good health. Stop using it.

Should I worry about overcharging my batteries if leaving them on the charger?

Quality modern chargers automatically stop charging when the battery is full. Just don’t leave highly discharged batteries charging unattended – have reasonable supervision the first hour.

What safety gear should I use when charging RC batteries?

As a minimum safety precaution, have a fire extinguisher nearby and avoid flammable fumes. For LiPo charging, use a fireproof charging bag. Some hobbyists use welding gloves, safety glasses and acid neutralizing agents in the unlikely event of a fire.

How can I get maximum lifespan out of my RC batteries?

Avoid running batteries all the way down each use, store them 40-80% charged, don’t expose to temperature extremes, charge at moderate rates between .5C-1C, and balance charge lithium packs. Also letrest before recharging if hot.
