Really impressive: 2 days from Tuesday evenings order to Thursday noon delivery, Cz to De, new record Banggood, 10 stars! The tool: speed from 20-225/min at no load, batteries half charged. Inside: simple speed regulator with a small heatsink, a DC-motor, one stage metal planetary gearing, and plenty of stinky grease. Cleaned it and greased it with something that's not smelly. The axle between motor and ratchet has a needle bearing, I'm impressed! The ratcheting mechanism seams to be hardened steel! Didn't measure the torque yet, but it's not bad. The housing is not very ridgit, but there seems to be some glassfiber in it. The batteries: I opened them, 4 screws T8. There are 18650s (6s), total ~25V, and a charger-circuit with balancing and temp-sensing inside the battery! On one battery the cells were between 3.75 and 3.85V, the other had one cell at 3.3V. I charged the cell up, I'll see how it behaves. Capacity: no clue, I guess it's 1500mAh, I'll test it. The battery housing has 3 contacts, marked +, - and "T". The tool uses + and -, the charger uses + and "T" for charging! I charged one battery: it's 24.8V, and the cells are between 4.11 and 4.14V, the balancer does a great job! The charger: I opened it, no screws, snaps to close. Simple switching supply, with 26.5V output (to + and T, be careful). I found a small solder residue, that might have shorted the DC, if I hadn't removed it... And be warned, there is not polarity protection on the battery housing, only some diodes seem to protect the circuitry, but I didn't try it... The DC has no full bridge rectifying. Charging seems to be a bit slow. Conclusion: this is not for powered cracking or torquing bolts. Crack them by hand, and then power them out or back in. A great tool, and much better than I hoped, I'd definitely buy it again. I could upgrade the batteries with better cells, and the charger could be modded for faster charging, but I don't know, if the board inside the batteries could handle it.

Q: What does the red hat do? Does it have any function or just for grip?

eatatjoes Better grip and reduce the pressure to your palm.

eatatjoes Good tool, two weak batteries

eatatjoes ViaPC usb-app more parameters are available. There is a current threshold "DfitterCur", default was 1500mA in my BMS. Below this value the BMS ignores the fluctuation in measured current and shows "0,0A", else "no charging", results in "no balancing". So just ignore it: balancing current is only 30mA, totally useless if your charging current is >1A

Fast delivery, nice bright enough light, but in my case a bad battery. The strong magnetic base holds the light very well. The LED head is twistable and has a stop inside to protect the wires from damage. The housing is very thin, will break, if one steps on it. The LED- driver has slow and slightly visible pwm dimming, the battery is protected (small board at the batteries side). The battery connections are welded. The wires from the batteries protection board to the driver and from driver to COB are very thin. The build quality is not the best. Cheap material, but with a nice rubber-like touch on the outside. There are some sharp edges (the light-gray stripes), but easy to modify after disassembling. The housing was badly assembled, it didn't fit well, and the rubber charging port's cover and the microusb port also didn't fit. After opening the housing I found the board wasn't placed correct in it's place. After fixing this, the housing fits nicely. And after deburring the grey parts the housing feels and looks very nice. Another thing: the battery is not fixed in the housing. It doesn't rattle, but it can easily move, if one drops the light. There is a plastic colum in front of the battery (very loose fit), and in my case this colum was broken. Maybe because of hard handling while shippment. At my first test the charge indicator showed a strange behaviour: when set to more than half brightness, it immediately switched from 4 to only 2 blue LEDs, and didn't come back to 4 when power was lowered. So I tested the battery capacity: from full charge (from light, only 4,1V), down to 3V, measured only 800mAh at 0,5A discharge. That's very dissapointing for a 18650 cell, and I will replace it with a good one. RecommendetjQuery111309923194701048156_1600459600806 I don't know. If you like to check it, and if you are lucky with a better battery it will be a nice work light. If you want to buy a good quality light, better stay away.
