Q: this board has built in bms?

spurgt af BG221154180 på 2021-01-19 05:38:22

brocak No, this has no BMS and the quality of this board is very poor. I ordered one and it just discharged deeply my batteries.

It seems to be well made, but I need a further testing. It should manage up to 100Amps output but I doubt about it. I thing that the right output should be around 30-40 Amps which can handle.

Q: Can this be a good cable to build 3d printers harness,wiring for stepper motors with max current 24v 4A? Is this a silicon cable?

Good DC to DC changer. Useful for your DIY projets. Up to 300W just with the quick cooler othervise it can burn-out very quickly. Good design with the srew in conductors sockets. On-off switch is also advantage. Just dont exceed the input voltage it has no overvoltage input protection. The parametric data included which is great.

Its a tiny and small accu LED light with enough of a light output to be able to orient in dark room. Its not for reading or when you need more light for some work. For the dark corners at home it is ideal. It can be glued by the tapes to any surface. It has own accumulator so only thing what you need is to take out the battery part and bring it to te USB charger. Two modes- still shining or at the body temperature sensor and second sensor measuring outer light level which save the battery. I have to test a period of light output also. Overally a good designed house light for kitchen or to path over your home. Good.

Q: I dont see any temperature sensor for the battery, does it have some?

spurgt af micminarik på 2020-12-14 09:23:09

brocak No,this is a very cheap BMS so it doesnt have any temprerature sensor. If you need a proper one, you have to pay much moore for it !

US$12.99 US$17.99

Q: Can this be used with a 4S x 10P pack of LiFePO4 batteries to make a replacement for a car battery? Or as a second battery in a car, along with the regular lead-acid battery? What is the maximum number of batteries in parallel that this BMS can manage?

spurgt af tom_kasper på 2019-11-23 10:21:16

brocak Its a 4 serial BMS so it means 3,2x4=12,8V nominal. The number of paralel cells is just on your choice, but you must respect the maximum Amp output from BMS.

Q: May I Know, What is Protected and Unprotected Batteries? Pls. Elaborate...

spurgt af jeffkribo på 2019-11-16 10:16:40

brocak Best is to use an unprotected cells because of low inner resistance and high current output.

As it is not standart size battery, I cannot recharge it by my charger Opus BT3200 because its oversized to it. I need to spot weld the contact to be able to recharge it and to test a real capacity. It will be doing by constant current powersource and I will measure the watt hours than. After this test I will public the results here. Looks impressive in size and promised capacity and I wanna make a battery pack from this cells if succes it pas my tests.

This is simple use LED floodlight with three modes of output light - high power low power and blinking mode. It has two LED COB chips on its body and front plastic glass cover upon them. It has a nice flood cover output. Actually it is not a 30W output at all but somewhere near 5W in reality but its enough light for most applications. It is suitable for fishing, turism, hunting or to any worshop. It can be used as an emergency powerbank if fitted with two LIion 18650 cells and better to use protected ones as it does not contain any low voltage protection inside. Also you can use 4xAA cells what is handy. I like the style of this COB LED lights. It is robust and easy to operate even in harsh enviroments. IP67 cover is not as good as it should be because it has no seals on battery compartment. Overall experience is just good.

Geat use powerbank with the two standart USB output and one USB-C output. It can recharge 3 devices at one time which is great. If you load it wit the 3400mAh quality 8 cells you will get an fantastic 30000mAh powerbank. It is for DIY makers like me,you have to recharge first all the cells for the same voltage and then put them to the spring chasis. You have to use the exactly same cells to work properly. Two LED diodes is a bonus. The quality is good but not the top. Good toy to make.

It is a miniature 12V DC water pump submersible or stand alone. The best thing is that it can handle a hot water up to 100°C and can be submerged in 60°C water so it can be used in water heating system for solar or other systems. It has a capacity 800l per hour and it manage transport water up to 5m high. Very good pum with many practical use.

This is a great portable Liion 18650 or AA battery LED light. I already bought around 10 pcss and still satisfied with them. It is light weight and well ballanced. The setable handle is great and the light output as well. Three light modes high low and strobe. Emergency USB output is a bonus. Great and sturdy made and can light for long time.

Q: Is a power supply for charging this item supplied? If not, what power supply for sale on Banggood could be used? What is the size of the input adapter plug? What is the size of the output plug that has the variable voltage available?

spurgt af Laurie på 2018-08-27 07:24:55

brocak The input connector is very small diameter, some 2mm and the output is 3,5 mm I gues. You need to charge it by CC powersource with the maximum output of 8.4 Volts as they are two in series and two paralel.
