JUNSI iCharger 4512 DUO, 1-12 LiPo
Charging power 2x2000 Watt

All Junsi chargers of the X and DUO series are developed and approved for use in model making. Industrial use is not intended and therefore not permitted! All Junsi chargers may only be operated with power supplies developed for model making! AGM batteries may not be charged in the PB program!

With the new iCharger 4512DUO, the renowned manufacturer Junsi has technically completely renewed the well-known 4010DUO charger.

The new 4512DUO charger combines the advantages of the well-known Junsi iCharger 4010DUO with the latest technology, thus offering significantly more power and new functions.
The two charging outputs are equipped with high-current XT90 connectors to ensure continuous power transmission.

The technical data is impressive: 2800W charging power (from >40V), 1-12s LiXx cells and up to 45 amps of charging current are sufficient even for large batteries with high capacity. Of course, all other battery types such as LiHV, LiIo, NiZn, PB, NiCd or NiMh batteries can also be charged.

The discharge power is 200 watts total (130W per output if only one output is used), but can be increased to up to 2800W by means of an external load (discharge resistor). Of course, the iCharger 4512DUO also supports regenerative charging. Here, the battery capacity of, for example, a full flight battery is fed back into the supply battery.

The balancer current of 4 amps total (2A per output) always ensures perfectly matched cell voltages.

A USB-C PD port for charging smartphones etc (5V/3A, 9V/2A, 12V/1.5A) or for software updates is also installed. The Micro SD slot can be used for logging data, but also for future updates.

A new feature is "Digital Power", where one output can be used as a stabilized power supply. The output voltage can be set from 2V to 50V, the current from 1A-45A (Please note that an appropriate power supply must be provided for this!)

A servo tester is also integrated, but please note that an external power supply is necessary for this!

The menu navigation is almost identical to the well-known Junsi iCharger 3XXDUO, 45X DUO or 4010DUO.

A 2.8" IPS LCD display ensures good readability even in low light conditions.

Instructions in English are included with the charger in the form of a CD; the German version can be downloaded from our website.

ATTENTION! To charge 12s, a 13-pin XH connector strip on the battery is required! NO balancer board is included for charging, e.g., 2x6s as 12s! (CB-12XH/EH)

For 10s as 2x 5s, the well-known CB-1010 with the 11-11 Wire can be used!

* Charging a 12S battery with 2 balancer plugs *
You will need a board with a connection cable suitable for the battery and the charger. Then strictly observe the following order:
- First connect the charger to the power supply or a supply battery. If you are using a power supply, turn it on first.
Caution! Only connect the batteries to the charger when they are correctly connected to the balancer board!
- First insert the first balancer plug of cells 1 - 6 "battery negative side, black cable" into the matching 6S slot of the board from the negative side,
- then insert the second balancer plug of cells 6–12 into the second 6S slot from the positive side "battery positive side, red cable". Now connect it to the charger. If it hasn't sparked and smoked by then, you've done everything correctly!
- Only now connect the thick red main charging cable "+" of the battery to the charger, then the thick black main charging cable "-".

Connections: Avoid short circuits, otherwise there is a risk of injury! This described sequence also applies when charging several batteries in series!
You are responsible for any damage and defects that may arise from non-observance!
