Advanced Radio I-Charger - Intelligent Micro Charger
This new “ON BOARD CHARGER” from Advanced Radio is the solution to charging your Duralite Sentinel batteries!
The I-Charger is designed to be used with batteries that have an internal battery balancing charge circuit. If you are an advanced user then you know that some battery chemistries do not require charge balancing however Advanced Radio states that the I-Charger should be used only with self-balancing batteries.
The intelligent battery management system, IBMS, is designed to be a part of the airframe but can be used externally as well.
The Advanced Radio I-Charger is the world’s first Automatic Intelligent charger designed to mount directly in your giant scale model. Gone are the days when you had to carry a charger to the field. All you need with the Advanced Radio I-Charger is a 12 volt DC power supply.
The I-Charger handles up to 4 x 2 cell Life, Lion and/and Lipo chemistry. You simply set the chemistry on the slider switch plug in your battery and when ready to charge your batteries, connect 12 volts. It's just that easy.
The Advanced Radio AR I-Charger can be purchased in 2 battery pack, 3 battery pack or 4 battery pack configuration and comes ready to charge your receiver, ECU and ignition batteries.
During the design phase the challenge was to deliver a light weight compact charger that offered features of a much larger charger. A charger that can be mounted in your model. Combining micro size, large charge current and best practice safety design was a challenging task. We selected a design for what we know as best practice for safety charging and used only the highest quality components. Each charge board in the I-Charger stack is a separate advanced monolithic battery charger. Many other multi charger designs use a cheaper multiplexed battery charging circuit. With the I-Charger each battery is monitored by its own separate charge board. This design while expensive provides the best charging and safety option for your very expensive model.
How it works:
After setting up the desired battery pack chemistry (Life, Lion, LiPo) via a small slider switch, you simply connect a 12 volt power supply to the I-Charger.
Once power is applied the charger will:
Battery over temperature safety:
I-Charger has provision for Lithium battery temperature monitoring. This feature monitors battery pack temperature using the optional temperature sensor. You simply attach the temperature probe with tape and if the battery temperature moves outside a safe charging range of 0°C to 40°C, the I-Charger suspends charging and signals a fault condition (Red LED). Once temperature returns to the safe range then charging will continue.
Battery Bad Detection:
I-Charger also supports bad battery detection, which triggers a system fault (Red LED) if a battery stays in precondition mode for more than one eighth (23 minutes) of the total charge cycle time.
Charger over temperature safety:
During the charge process the I-Charger monitors each charger board individually. If the temperature of an individual charge board reaches a high temperature condition then the charge current on that charge board is reduced to maintain a safe operating temperature range. This applies to each individual charge board.
I-CHARGER MOUNTING POSITION PLEASE NOTE:
The Advanced Radio I-Charger will get hot when charging batteries. YOU MUST provide adequate space when mounting the I-Charger in your model. It is advised that you mount the I-Charger vertically so that thermal cooling is maximized. Failure to provide an adequate cooling environment will result in lower charge currents and a longer charge time.
While the I-Charger employs the utmost in safety design, Advanced Radio states that you should never leave Lithium batteries unattended while charging.
Wall adapter specifications: 12 - 15 volts, 5 - 6 amps max (not available at this time - find one at your local electronics store)
