Perfect for All RC Hobbyists

With the ability to charge a wide variety of battery types in various sizes and capabilities, the Reactor 500 is ideal for all car, airplane and boat RC enthusiasts.

Microprocessor Controlled

The optimized microprocessor controller perfectly controls the charging, balancing and discharging, and prevents the overcharging of all types of batteries. The microprocessor disconnects the charge current and sounds and alarm if there is a malfunction.

LiPo & Li-Ion Charger/Balancer

Safe charging of lithium polymer (LiPo) or Lithium-Ion (Li-Ion) batteries from 1S up to 6S. Maximum charge voltage of 4.2V/cell for LiPo, 4.1V/cell for Li-Ion; up to 1C fast charge per cell.


Charge the latest LiFe batteries (up to 6S) with complete confidence. Maximum charge voltage of 3.6V/cell up to 4C fast charge per cell.

NiMH & NiCd Battery Charging

Charge all current NiMH or older NiCd cells at up to 5 amps for safe and fast charging, from 1 to 15 cells.

Pb Battery Charging

Pb (lead-acid) batteries from 2-20V can be easily charged for engine starters, etc.


Discharge cells at a safe rate to maximize capacity and lengthen life. NiMH and NiCd discharging from 0.1 to 1 amp. Individual lithium battery cell discharging for maximum safety.

Storage Mode

Choose this easy storage charge mode for confident long-term lithium battery storage.

Extra-Safe Charging

Safety limits include: voltage, current, capacity, time and input power. Delta-peak sensitivity prevents too much voltage going into the battery; automatic cutoff when the battery reaches maximum capacity; maximum charge time can be set; lower input voltage level.

Multiple Charging Profiles

Simplify charging by storing up to 5 battery pack profiles for charging different types of car/plane batteries, transmitter pack, receiver batteries and more.

Easy Cycling of Battery Packs

Revive battery packs for periodic maintenance or after a long storage. The charger safely charges the battery to full capacity, then slowly discharges it to a safe level up to 5 times. Ideal if you don’t use your batteries regularly.

Multiple Connectors Included

Power inputs:

Standard US 3-pin laptop power supply connection for 100-120V DC, 12V power lead plus crocodile-style clips for car battery
