Review: tiny and very very good - 12/27/24: I tried non-constant-current supplies but the 8A capability of these bms’ is too much for the 3000mah Samsung 30Q batteries I’m using (which spec 1.5a nominal charge and 4a quick charge. Two in series is double the volts @ same amps so I have to limit the charge current to 4a or less and I’m choosing to set it at 3a so it can drive the pi’s and router when 12v is available.) There is no interruption in supply power when the 12v input is cut off, only a slight change in the voltage from the charger’s 9v down to the batteries 8.4v. orig: These are very small, a little over 1” long. The solder pads are very nice and quite easy to get at with a solder tip plus they take solder very nicely. The two I set up so far worked perfectly. I put them on the back side of 2x battery holders and the solder pads were perfectly positioned to take the wires from the holders tabs in straight runs. Even charging at 8a these only get slightly warm, I didn’t run them longer than maybe 10 min but if they were going to get HOT they would have by then. I’m impressed. I’m using these to make a UPS for two pi02 raspberry pi’s and a Slate router. I feed it from a constant current Drok 5a variable DC-DC converter and this works perfectly. The bms’ sense the battery voltage and apply a charge if needed automatically shutting off once the voltage rises. I am experimenting with what regulator to use to feed the battery voltage to the USB sockets for the rpi’s and the router - a cheap 3a unit may run hot at the ~2a I expect will be needed. Another Drok 5a converter would work but might be overkill. I could not be happier with these.
Review: Works fine - Used these to build a 2S3P Li-Ion battery pack for a Fluke ScopeMeter 199C, which originally came with a NiMH pack (had to modify the charging circuit in the scope to reduce the charging voltage from 9V to 8.4V). As another review said: the output on P+/P- will be zero, even if the batteries are fully-charged. Just apply a normal charging voltage (between 7.4 - 8.4V), then the BMS will activate and the output will be active.

## Features

- HIGH-ACCURACY, HIGHLY DURABLE: High-accuracy voltage detection circuit, fine workmanship and durable, Effective life greater than 50000 hours.
- Use for variety of capacities and various shapes 3.7V lithium batteries,Massager battery pack, LED light backup power supply, solar street light battery pack, monitor standby power supply, etc.
- Over-discharge protection, overcurrent protection, overcharge protection, short circuit protection; A combination of 4 safety features that work together to provide ultimate protection for your devices.
- MOS transistor can control the battery charge and discharge, low standby current consumption.
- ATTENTION: Strictly according to the diagram wiring: B+: Battery V+ Positive, B-: Battery V- Negative, P+: Output / Charging V+, P-: Output / Charging V-, MB: The connection point between the batteries.Otherwise it will cause damage to the chip. Do not mix the good battery and poor battery to use. The internal resistance of 3 battery capacity are closer will be better.
