iMax B6AC V2 Charger: Features, Specifications and Buying Guide
, by UMW Media, 7 min reading time
Choosing the right RC battery charger can make battery maintenance easier, especially if you use different battery types for your models. The SKYRC iMax B6AC V2 charger is a multifunction charger designed to charge and discharge compatible LiPo, Li-ion, LiFe, NiMH, NiCd and lead-acid batteries.
Unlike chargers that require a separate external power adaptor for AC operation, the iMax B6AC V2 supports a direct AC input as well as DC input. This makes it a practical option for RC hobbyists who want a versatile charging station for their workshop or hobby setup.
Available from Hobby Inn, this bundle also includes a LiPo safe bag for battery handling and storage.
What Is the SKYRC iMax B6AC V2 Charger?
The SKYRC iMax B6AC V2 is a microprocessor-controlled RC battery charger and discharger with an integrated lithium battery balancer. It is designed to support several battery chemistries and offers different charging modes to suit compatible packs.
With a maximum charging power of 50W and a maximum charging current of 6A according to the product description, it is suitable for hobbyists who need a multifunction charger within these limits.
Its main features include:
- AC and DC power input options
- Balance charging for compatible lithium battery packs
- Charging and discharging functions
- Fast-charge and storage modes for compatible lithium batteries
- Automatic charging current limiting
- Battery capacity and processing-time limits
- Temperature threshold settings, where supported
- Cyclic charging and discharging
- Input power monitoring
- Data storage and loading
These functions give hobbyists more control over battery charging and maintenance, provided the correct settings are selected for each battery.

What Makes the iMax B6AC V2 Different?
1. Built-In AC Input
One of the main advantages of the iMax B6AC V2 is its AC input, rated at 100–240V. This allows it to connect to a suitable mains supply without requiring the separate external DC adaptor typically used with a DC-only charger.
It also supports an 11–18V DC input, providing another power option when used with a compatible source.
Always follow the manufacturer's instructions for the correct power connection and operating conditions.
2. Balance Charging for Lithium Batteries
The integrated lithium battery balancer helps manage individual cell voltages when charging compatible multi-cell LiPo, Li-ion, LiFe and lithium high-voltage batteries.
Balance charging is particularly useful for multi-cell battery packs because the individual cells may not always remain at identical voltages.
Select the correct battery chemistry and cell count before starting a charge. Do not use a charging programme simply because the connector fits.
3. Charging and Discharging Functions
The iMax B6AC V2 can charge and discharge compatible batteries. The listed maximum discharge power is 5W, so discharging is subject to this relatively low power limit.
These functions can help hobbyists manage their batteries, but the appropriate procedure depends on the battery type and its manufacturer's guidance.
4. Storage Mode
The charger includes a storage mode for compatible lithium batteries. This helps prepare batteries for storage at an appropriate charge level rather than leaving them fully charged for extended periods.
Follow the battery manufacturer's recommended storage voltage and conditions. Storage mode does not repair damaged batteries or make unsafe packs suitable for use.
5. Adjustable Safety Limits
The product description lists several monitoring and limit functions, including automatic charging current limiting, capacity limits, processing-time limits and temperature thresholds.
These features can help manage the charging process. However, they do not remove the need to supervise charging, inspect batteries and select suitable settings.
Which Batteries Can the iMax B6AC V2 Charge?
The charger supports several battery chemistries, but each requires the appropriate programme and settings.
LiPo batteries
LiPo batteries are common in RC cars, aircraft, drones and other radio-controlled models. The listed specifications support compatible lithium-polymer battery packs from 1S to 6S.
Use the correct balance-charging programme, cell count and charging current for your battery.
Li-ion batteries
Compatible lithium-ion packs are also supported within the charger's specified limits. Check the pack's voltage and manufacturer's instructions before charging.
LiFe and LiHV batteries
The product description lists support for lithium iron phosphate (LiFe) and lithium high-voltage (LiHV) batteries. These chemistries have different charging requirements, so selecting the correct battery type is essential.
NiMH and NiCd batteries
The charger supports compatible nickel-metal hydride and nickel-cadmium packs containing 1–15 cells, according to the supplied specifications.
Lead-acid batteries
The listed supported lead-acid battery voltage range is 2–20V. Check your battery's specifications and use the correct charging programme.
Is the iMax B6AC V2 Suitable for Your RC Setup?
The SKYRC iMax B6AC V2 may be a suitable choice if you want one charger for several supported battery chemistries and need both AC and DC input options.
It may be useful for:
- RC car and truck hobbyists using compatible rechargeable battery packs
- Model enthusiasts who maintain different battery chemistries
- Hobbyists who need balance charging for lithium batteries
- Users who want charging, discharging and storage functions in one unit
- Workshop setups where direct AC input is convenient
Before purchasing, compare the charger's power and current limits with your battery requirements. A charger that supports your battery chemistry may still be unsuitable if its output limits do not meet your needs.
Safe Charging Tips for RC Batteries
Correct charging practices are essential for battery care. Follow these precautions whenever you use an RC battery charger:
- Inspect batteries, wires and connectors for visible damage before charging.
- Select the exact battery chemistry and cell count.
- Set a charging current recommended by the battery manufacturer.
- Charge in a suitable, well-ventilated area on a non-combustible surface.
- Never leave charging batteries unattended.
- Stop charging if a battery becomes unusually hot, swollen or damaged.
- Keep batteries away from flammable materials.
- Follow the manufacturer's guidance for storage and disposal.
The included LiPo safe bag is a useful accessory, but it cannot eliminate battery-fire risks or guarantee that a battery failure will be contained.
