42V 90N.m 3/8" Cordless Electric Ratchet Wrench Tool 2 x Battery & Charger Kit
A part of the review has been auto-translated.
A nice corner cordless gykovet. I received it with charged batteries. First impression-good. Its strength is about 20 Nm. The future will show what longevity will be in my garage. You have no right to compare it with the pneumatic model, there the work is serious!!! Thanks Banggood!!!
coming fast! it seems very nice and I want to make some test . the motor isn't brush less. I see some sparks during the test.
suberb
everything arrived as described thanks to the seller
Urządzenie ogólnie słabe. Problem z odkręceniem śrubek bez wcześniejszego luzowania innym kluczem. Przy pierwszym odkręcaniu już pojawił się dym z silnika. Podejrzewam że moc jest sporo zawyżona bo na pewno nie ma 90 Nm.
Product ok. Not so well packaging.
era que esperava produto bom de qualidade recomendo
Great product thanks
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.
