As you can imagine, I’ve looked at many chargers, lots of them have proven to be disappointing, many are just plain boring. Early days but this ISDT C4 charger (from Banggood) looks neither. Indeed it looks marvellous.
From initial impression through to operation this looks like a complete winner to me up to now. 4 sides of the manual are in English, certainly enough to get started. The unit does charging, discharging, storage charging, activation (for batteries that look dead, I so wish other chargers would do this), analysis and USB charging (to charge phones)….
Firmware can be upgraded online (how many chargers do that) and the unit handles NiCD/NiMH, Li-Ion, LifePO4, Eneloop and more, charging 26650 batteries at default 2.5 amps (the 12v power supply
The display shows voltage, capacity, charge current and a nice colour graph. There is a touch panel to the right of the IPS LCD colour display panel.
Impressed? Yes I am. Incidentally where you see “capacity” below, bear in mind you need a complete discharge and recharge to get a proper value there.
Maximum total charging power is 30W. Clearly to do this justice, I’ll have to fully discharge some batteries and then fully charge. All that once we’re settled in Spain for the summer.
