That would work; you need a 48V power supply.

... You're correct in that the charger does not balance cells, but the BMS balances if needed when at the float voltage and charge current is small. If you shut the charger off early rather than lower the float voltage, current remains high and balancing does not take place.
Did you find that graph somewhere, or is it from your own set of measurements?

Quote from: Bronco99 on November 26, 2023, 03:34:54 PMBoth devices do the same thing. If one battery is at a higher voltage than the other, the device will draw current from that battery only. Once voltages match, the device will draw current from both.
Ok mate good info thanks. But will a cheaper blender (not a datex) equalise 2 48v batteries regardless of voltage level or do they need to be equal voltage beforehand. I?m trying to figure exactly what the datex does as opposed to a (much) cheaper blender 😂

Our RadMini ST2 has a USB charging port, but it isn't working at all. I tried plugging in an (e)scape brand bluetooth earbuds charging case, with the specs "Input: DC 5V | 1A max". Both the case and the earbuds are only 3.7V. It should not be overloading the charging port, but there's nothing. Also nothing for my "moto e" phone.
I cannot find any way to open the LCD display to check for a fuse or loose connection.
The RadMini ST2 manual says:QuoteNotice: The USB Charging Port charges many, but not all, devices. The USB charge rate from the display will supply power to many phones, but larger phones, which require higher power in order to charge, may not register charging. If the display indicates ?USB? it will supplement battery power for the phone, but the state of charge of the phone may still decrease.So, when it does work, it should at least extend a phone's battery life.

What you don?t realize is the mission battery will kill the electronics in your bike.
Constantly leaving it on the charger well after the light goes green on the charger will kill the battery in a year or two.
