Palm-size two-channel DC fast charger with balancer for 1-16 cells NiCd / NiMH , 1-6 cells Li - Po / Li-Ion / Li -Fe / LiHV /U - LiHV , 2-20 V Pb, with a Power output of 0.2-10A (max. 2x250W or 1x 400W/0.2-16A in parallel operation). Input voltage 10-30V DC. Internal resistance measurement, USB-C port for firmware update.
The KAVAN C50 Duo 2x250W palm-size charger is an intelligent two-channel charger that is powered by a car battery or a stabilized power supply. It has a very simple and intuitive operation. The C50 Duo can charge the following common cell types (NiCd, NiMH, LiPo, LiHV, ULiHV, Li-Ion, LiFe, Pb). A plus is the built-in six-channel balancer to ensure that lithium batteries can also be charged safely. The charger is equipped with a color LCD and has buttons for programming. These enable a very comfortable and clear programming of the charger and its settings.

In addition to a compact "palm-sized" also called palm-size design, it also has an intuitive handling and operation. The following features are worth mentioning:

A program for new high-voltage lithium batteries LiHV with an output voltage for charging of up to 4.35 V and ULiHV with an output voltage for charging of up to 4.45 V
The possibility of synchronous operation of both channels for charging two identical batteries or parallel charging of one battery with up to 400 W power
An adjustable end voltage for charging and lithium batteries (this allows for gentler charging which pilots like or brutal overcharging which rc car drivers prefer.
An adjustable end voltage for charging lead-acid batteries (1.90-2.45 V; this allows all types of lead-acid batteries to be charged)
Basic functions and parameter overview:

Input voltage 10-30V DC (XT60 port); For the full range of functions of the charger, i.e. max. output power, there should be at least 24 V voltage.
For charging 1-16 NiCd / NiMH cells, 1-6 Li-ion/ LiPo / LiFe / LiHV / ULiHV cells or 2-20V lead-acid batteries
Adjustable charge current (0.2-10.0A) on each channel (up to 250W)
Maximum output power for charging 1x400 W (charging current 0.2-16.0 A) in parallel charging mode
End of charge via Delta-Peak procedure for NiCd and NiMH batteries
Lithium and lead-acid batteries are charged via "constant current / constant voltage" (CCCV).
Adjustable delta peak detection sensitivity for NiCd and NiMH batteries
Adjustable end-of-charge voltage for lithium and lead batteries
Charge mode allows charging of lithium batteries with or without a balancer
The C50 does not have a discharge mode
Channel 1 (CH1) can be used as a stabilized voltage source with adjustable voltage of 5-24V and current of 0.2-5.0A
Easy firmware update via USB-C port
Backlit LCD display with clear and easy menu and parameter monitoring while charging
Programming buttons for easy programming and operation of the charger
Safety is ensured by a variety of warnings - e.g. wrong input voltage, wrong connection, wrong battery or its condition, wrong polarity etc.
Fan for forced cooling
Compact plastic housing with very small dimensions
The charger is equipped with XT60 sockets on both channels and universal JST-XH sockets as service connectors, allowing a direct connection from charging cable and JST-XH service connectors to 2-6S packs. If you use battery packs with XT60 and JST-XH connectors, you do not need any additional cables or adapters. If you are using service cables from another system, use a standard SkyRC or RC system adapter.

The set contains:*** C50 Duo charger, screensaver, user manual.
