Palm-size dual channel DC fast charger with balancers for 1-16 cells NiCd/NiMH, 1-6 cells Li-Po/Li-ion/Li-Fe/LiHV/U-LiHV, 2-20V Pb with current 0,2-10A (max. 2x250W or 1x 400W/0,2-16A in parallel mode). Power supply 10-30V DC. Internal resistance measurement, USB-C port for firmware update.
The KAVAN C50 Duo 2x250W miniature charger is a two-channel smart charger with power supply from a car battery/stabilised mains supply and a very simple and intuitive operation. C50 Duo can charge common cell-types (NiCd, NiMH, LiPo, LiHV, ULiHV, Li-ion, LiFe, Pb), plus it features built-in six-channel balancers to ensure safe charging of Lithium batteries. Charger is equipped with a color LCD and programming buttons, which offer you more comfortable and very clear parameter setting, control and monitoring of the charging process.

In addition to a compact „palm-size“ design and intuitive operation, worth a special mention is:

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
Option of synchronous operation of both channels for charging two identical batteries or parallel charging of one battery with up to 400 W of power
Adjustable end voltage for charging lithium batteries (allows more gentle charging that pilots like, or brutal over-charging suitable for car guys
Adjustable end voltage for lead-acid battery charging (1,90–2,45 V; allows charging of all types of lead-acid batteries)

Basic features and parameters overview:

Power supply 10–30 V DC (XT60 port); for full use of the charger’s max power output, the supply voltage should be at least 24 V
For charging 1–16 NiCd/NiMH cells, 1–6 Li-ion/LiPo/LiFe/LiHV/ULiHV cells or 2–20 V lead-acid batteries
Adjustable charging current (0,2–10,0 A) in each channelů (up to 250 W)
Max power output for charging 1×400 W (charging current 0,2–16,0 A) in a parallel charging mode
Charging termination via delta-peak automation for NiCd and NiMH batteries
Lithium and lead-acid batteries are charged via „constant current/constant voltage“ (CCCV) method
Adjustable delta-peak detection sensitivity for NiCd and NiMH batteries
Adjustable end voltage for lithium and lead-acid battery charging
Charging mode allows charging of lithium batteries with or without balancer
C50 doesn’t have a discharge mode
Channel 1 (CH1) can be utilised as stabilised power supply with adjustable voltage of 5–24 V and current 0,2–5,0 A
Simple firmware update via USB-C port
Back-lit LCD with clear and simple menu and parameter monitoring during charging
Programming buttons for simple setting and operation of the charger
Safety is ensured by a number of warnings – incorrect input voltage, wrong connection, insuitable battery or its state, incorrect polarity etc.
Fan for forced cooling
Compact plastic case, very small dimensions

The charger is equipped with XT60 sockets in both channels and universal JST-XH sockets for service connectors, allowing direct connection of power cables and JST-XH service connectors of 2–6S packs. If you are using packs with XT60 and JST-XH connectors, you don’t need any charging cables or adapters. To connect service cables of a different system you can use standard adapters SkyRC or RC System.
