Features
n
Simple to operate: just connect the Cellpro 4s charger between a power source and a pack.
No jumpers, plugs or dials to set! Charger automatically determines pack capacity and sets
optimal current, then dynamically adjusts charge rate as needed. Manual charge rates of
0.25A to 4A (in 0.25A increments) allow for special situations.
n
Charges Lithium Polymer, Lithium Ion, Lithium Manganese and A123© chemistries. Adapt-
ers are available from FMA Direct.
n
Each cell is charged independently, providing exceptional charging safety and elevating RC
packs to the safety level of cellphones.
n
Charges LiPo packs having one to four cells and any capacity up to 24Ah. Typical packs of
up to 3Ah capacity charge in 50 minutes or less using charger’s 1.4C Auto Current Mode.
n
Multifunction display shows operating mode, individual cell voltages, charge current, supply
voltage, and amount of charge (mAh) put into pack. Plus, the unique Fuel display shows per-
cent capacity remaining in a pack.
n
Viewer software (a free download) displays real-time data and graphs.
n
Latest technology provides the ultimate in safety. Even charges packs having hidden physical
damage without danger of fire. A pack will not charge if individual cell voltages don’t equal
total pack voltage.
n
Cell balancing to 10mV and automatic overcharge protection assure longest pack life. Auto-
matic temperature monitoring prevents pack overcharging at low ambient temperatures and
charger damage at high ambient temperatures.
n
Low Voltage Restore feature automatically attempts to repair overdischarged packs. Cells
discharged as low as 0.5V may be repaired to as much as 98% of capacity.
n
Cold Weather Charge stops charging at 4.10V/cell when temperature is below 55°F to prevent
cell damage.
n
Operates from any 10–16V DC power source. Inputs and outputs are protected against re-
verse polarity.
Precautions
n
Follow all instructions in this manual to assure safe operation.
n
Always watch LiPo packs while they are charging. Never leave LiPo packs unsupervised dur-
ing charging.
n
See additional warning sheets provided with this charger and FMA LiPo packs.
n
Follow all guidelines for charging, discharging, handling and storing LiPo cells.
