So there's something to be added to my already overflowing to-do list. ... You might also look for zb2l3.I bought several from Ali-Express for about 2 EUR each. The circuit is trustworthy. The batteries to be tested can have up to 15 V. Two 7.5 ohm/5W resistors should be included. The threshold voltage (cut-off voltage is adjustable). This is probably the cheapest solution.
