The HOTA range of charger/dischargers is quickly becoming renowned for their quality, reliability, and numerous great features. This amazing 1000W 4-channel charger/discharger can charge 4 x 1~6S LiPo and batteries at up to 4 x 250W, or you can combine 2 outputs together to achieve up to 500W. It offers loads of protection to safeguard against damaging itself or your battery packs such as temperature protection, over-voltage, over-current, input and output reverse protection, short circuit protection, and much more (see the attached manual for the full list). It utilizes a highly optimized algorithm for charging management, and its advanced circuit design offers a 94% operating efficiency.

It features a simple system for programming, there is a channel switch key for selecting which channel you wish to program and a speed shuttle key for all the other programming selections. This speed shuttle key is pressed to enter the task, scrolled to adjust the task, then pressed again to enter the task, all very straightforward and simple. It also has a 2.8″ (320×240) 260000 colors IPS display which makes the whole user experience a very easy and simple affair. A unique feature of this charger is that it recycles the discharge power when being used to discharge a battery. This regenerative discharge takes most of the output battery’s energy and puts it back into the input battery in a balanced, environmentally friendly way.

The HOTA F6 has numerous ports, on the input side, there is a standard XT60 DC port for the input power of 10.5~30V DC. Then on the output side, there is a multi-function port, 4 x XT60 output ports, 4 x 6S balance ports, dual 5V (type A) USB port, and a Type-C interface for firmware updates. The multi-function port has a Futaba/JR style connector which can be used as a servo tester for testing your servos or for testing the output of your receiver and transmitter.

Overall this is a fantastic, user-friendly 4-channel charger/discharger that will charge or discharge 4 batteries simultaneously, or you can combine 2 outputs for even greater charging power. It is suitable for LiHV, LiPo, LiFe, LiLon, Lixx, NiZn, NiCd, NiMH, Pb, and Eneloop batteries and each port can charge/discharge different chemistry batteries at the same time. All this can be done in your workshop if you have a suitable power supply or out in the field when connected to a DC battery source.

ISDT is renowned for its ergonomically designed, small, state-of-the-art battery chargers and accessories. The K4 smart charger continues this great pedigree of efficient and user-friendly chargers.

The ISDT K4 is a simple to use, yet powerful, no-nonsense dual input (AC/DC) charger that can charge two battery packs simultaneously. It has the ability to charge 2 x 8S LiPo, LiIon, or LiFe, 7S LiHV, 14S Pb, or 18S NiMh/NiCd battery packs at up to 20A. Also, each channel can operate independently of each other, meaning that two different sizes or different chemistry batteries can be charged at the same time. You can even combine both channels in parallel for synchronous balance charging to achieve even more output power. The max charging current on AC power is 400W per channel, and on DC power it is an incredible 600W per channel. The six programming keys (3 per channel) are simple and intuitive to use in conjunction with the color LCD display screen.

To cater for better cooling, the unit has a carefully designed, and optimized internal structure. This is coupled with a ball-raced fan to promote an active cooling system. Outputs include 2 x XT60 male connectors for charging, 2 x XH-JST 8S balance ports, and a micro USB port for updates. The power input of 10~34V (DC) is connected to the charger via a female XT60 connector, and for AC use a mains power lead with an EU plug is supplied.

Features:
• Will operate from DC and AC power sources
• Ability to charge 2 battery packs independently
