Not many stars, I really do like this, but it could be SO much better! For a device you can plug in and see levels of charge immediately, without having to wait for it to scroll through several digital readouts is quick and efficient when you have loads of batteries. However, there are 2 drawbacks: 1. The unit price is 3 times more than a digital readout type, there is no buzzer, so why the expense? 2. The voltage range is ONLY 3.5 to 4.2v. The useable voltage in lipo chemistry is 3 to 4.2v, so where Are the 3-3.5V indicators? I have several lipos that I use as utility batteries and I need to use the whole voltage range and monitor down to 3v, but this device is useless for that. I just didn’t realise this limitation when ordering, I took the red LEDs to mean critical voltage. Banggood, please redesign this across the full voltage range, 3-4.2v, even if you remove some of the intermediate voltage steps, so it would read 3.0, 3.1, 3.2, 3.5, 3.7, 3.9, 4.1, 4.2 red. amber. green. white And please reduce the price, £7 for a batch of LEDs, it’s too much. if these were redesigned and £2 each I would buy 10 at a time.

They imploye blinking leds for volts below 3.6 The LEDs are bright and seem to be acceptable in accuracy. I can see individual cell voltage at a glance These are ideal. Maybe a little bit fragile as they are. However if I could suggest improvement, I would like to be able to set a low voltage alarm with this. Even better would be the development of versions for 10s 12s etc with jst connection to for visual battery pack check and BMS operation
