RSM Distribution is pleased to announce that due to a direct factory purchase we can now offer for sale the genuine Imax Quattro charger. Now you can charge 4 batteries at once. This charger works on AC at home and on DC at the flying field. Unlike similar chargers on the market that sell in the $299.00 price range RSM Distribution is offering the Imax Quattro Charger for only $189.99. Please see our posting in the Vendors' Corner.

Hi Chris:

Here's more data on the Quattro charger. It will answer all of your questions.

QUATTRO B6AC is a high-performance, micro processor control charge/discharge station with battery management suitable for use with all current battery types. With integral equalizer for six-cell Lithium-Ion (LiIon), Lithium-Polymer (LiPo) and Lithium-Ferrum (LiFe) batteries.

Maximum 6A charge current; can be powered by a 12 Volt car battery or from the 110V AC(US Version) or 220V AC via the built in switch-mode power supply.

And the circuit features four totally independent identical power outputs which are powered 50 watts each. Total powers are 200 watts. As a result , it can charge or discharge up to 4 x 15 cells of NiCd/NiMH or 4 x 6 series of Lithium batteries simultaneously. Quattro B6AC has four individual cell voltage balancer at each outputs, so it does not required any balancer separately when charging Lithium Battery (LiPo/LiIon/LiFe) for voltage balancing.

When a Nickel battery is fully charged, the unit terminates the process using the Delta-Peak method. Lithium and lead (Pb) batteries are charged using the CC-CV method.
 
QUATTRO B6AC allows you to plug 4 batteries into one charger simultaneously, and it will intelligently and automatically charge all 4 of them at once to their maximum capacity. On top of this, the batteries being charged do not even need to have the same configuration. You can connect different chemistry(Ni-MH/Ni-CD/LiPo/LiFe)batteries into any of the charging ports. No more staying up late for charging batteries.
 
Optimized operating software
QUATTRO B6AC features the so-called AUTO function that set the feeding current during the process of charging or discharging. Especially for Lithium batteries, it can prevent the overcharging which may lead to an explosion due to the user's fault. It can disconnect the circuit automatically and alarm once detecting any malfunction. All the
programs of this product were controlled through two way linkage and communication, to achieve the maximum safety and minimize the trouble. All the settings can be configured by users!

Internal independent lithium battery balancer
QUATTRO B6AC employs an individual-cell-voltage balancer. It isn't necessary to connect an external balancer for balance charging.

Balancing individual cells battery discharging
During the process of discharging, QUATTRO B6AC can monitor and balance each cell of the battery individually. Error message will be indicated and the process will be ended automatically if the voltage of any single one cell is abnormal.

Adaptable to various type of lithium battery
QUATTRO B6AC is adaptable to various types of Lithium batteries, such as Li-ion, LiPo and the new LiFe series of batteries.
 
Fast and storage mode of lithium battery
Purposes to charge Lithium battery varies, 'fast' charge reduce the duration of charging, whereas 'store' state can control the final voltage of your battery, so as to store for a long time and protect useful time of the battery.

Maximum safety
Delta-peak sensitivity: The automatic charge termination program based on the principle of the Delta-peak voltage detection. When the battery's voltage exceeds the threshold, the process will be terminated automatically.

Automatic charging current limit
You can set up the upper limit of the charging current when charging your NiCd or NiMH battery, it is useful for the NiMH battery of low impedance and capacity in the 'AUTO' charging mode.

Capacity limit
The charging capacity is always calculated as the charging current multiplied by time. If the charging capacity exceeds the limit, the process will be terminated automatically when you set the maximum value.
