In Simple mode when I insert 1.5V Li-Ion then it detects it as regular “Li-Ion” and Discharge mode doesn’t start.
In Pro mode when I insert 1.5V Li-Ion then charger offers only following manually selected modes: Li-ion, Li-4.35, LiFePo4 and Li-ion 1.5V, I can’t force it into Ni-Mh.
Hello, it is recommended to carefully refer to the product manual. The simple mode can only charge lithium-ion and ni-MH/cd batteries, which is simple and convenient
Pro mode can charge multiple types of batteries, you need to choose by yourself, but you need to long press the display button to enter and restart 
there’s something on the homepage left that could / should be corrected as well :
the text in the section “Current Button” still says “In Pro mode, BL4 can provide a wide range of current ranges from 50mA to 5000mA” …
the 5000mA (probably data from the SU2) should be replaced by 3000mA …
in the displays the 5000 / 5010 mA already had been removed, now there are shown currents up to 3000 / 3010 mA, that is matching …

A few of us have noticed that it is no longer possible to order the BL4 on Vapcell’s website or on the Vapcell Direct store on Ali Express.
Is it simply out of stock, or are you able to provide any clarification why or when it will be available again?
