When will the Wax WU388 lithium battery electric hammer be put into production earlier?

Lithium-ion batteries are divided into liquid lithium-ion batteries and polymer lithium-ion batteries. The electrolyte of lithium-ion batteries is fluid, so it is more unstable than lithium polymer batteries, and can be caused by a drop from an external force or by using a charger that does not meet the standards**. Many portable electronic products such as mobile phones and laptops use lithium batteries.

That is, many people have a "bomb" on their side. For the sake of safety, you must pay attention to the following points when purchasing. 1. Is there a clear capacity marked?

Batteries that do not have a clearly marked capacity (e.g. 1000mAh or 1000 mAh) are likely to be inferior or ** batteries. Many cheap batteries on the market are made of **battery core, **although cheap, but the life is short, the quality is unstable, and the use is not....

I don't know if you want to buy a plug-in or a lithium battery Anyway, I bought a lithium battery Vickers is really disappointed to me Actually designed such a garbage product It's really a garbage product After buying it, I didn't use it much within 1 year I haven't even charged it 10 times I said that charging 10 times may be a bit too much I really haven't used it many times Punching holes adds up to not even 200 This number of times is estimated to be quite a lot As a result, a few days ago, just punched a hole and didn't turn I think it might be a problem with the carbon brush I bought it in ** Just out of warranty The seller said to send it back for maintenance, if it is a carbon brush problem, you have to change the motor because the motor and the carbon brush are one As soon as I heard this, what kind of garbage stuff Even if it is designed as one, it will not work if it is not used much It will not work together for three days and two ends, I bought a motor myself and replaced it It can be used It is estimated that it will not take long A motor 80 I originally wanted to buy a good one that can be used for a longer time I have always bought this kind of tool It turned out to be really rubbish Whoever thinks it is suitable will buy it I am not buying Vickers anymore Even the drill with the battery I bought a battery More than a thousand in total.

"Lithium battery" is a type of battery that uses lithium metal or lithium alloy as the anode material and uses a non-aqueous electrolyte solution. In 1912, lithium metal batteries were first developed by Gilbert NLewis proposed and studied.

In the 70s of the 20th century, m s.Whittingham proposed and began research on lithium-ion batteries.

Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. Therefore, lithium batteries have not been applied for a long time. With the development of science and technology, lithium batteries have now become the mainstream.

Lithium batteries can be broadly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain lithium in a metallic state and are rechargeable.

The fifth-generation product of rechargeable batteries, lithium metal batteries, was born in 1996, and its safety, specific capacity, self-discharge rate and performance** ratio are better than those of lithium-ion batteries. Due to its own high technical requirements, only a few companies in a few countries are now producing such lithium metal batteries.

Fortunately, the rotary hammer from Wicks (WU340) and the electric hammer from Bosch (GBH2000DRE) have been operated by themselves.

In fact, other brands of electric hammers have also been experienced together, but according to the landlord's problem, it will not be mentioned here).

In the actual operation process, the contrast of punching a single hole is not obvious, and the vibration of the two machines is relatively acceptable, but when about 20 holes are punched down in a row, the contrast is more obvious, and the use of a Wicks electric hammer will be easier than the use of a Bosch electric hammer.

In order to verify this, we set up a slide bar device in the laboratory, and without applying external force to the two machines, Vickers punched holes significantly faster than Bosch (a difference of about 2 to 3 seconds for a single hole); When the same 5 kg weight is applied at the same time, the hammer punching time is comparable to that of Bosch.

In other words, in the actual drilling operation, it will be much easier to use a Wicks rotary hammer than Bosch.

All of the above are the experimental results of their own inverted experiments in the laboratory, not to do authoritative verification, professionals do not spray, thank you.

Of course, Bosch, who started with this hammer drill, is like a charging person looking for Hitachi, a carpenter looking for Makita, a small angle mill looking for a place, and a rich fool looking for a McTaibo...

Whistler started as an OEM, and things make do with it.

Other brands of electric hammers have also been experienced together, but according to your question, in the actual operation process, the contrast of punching a single hole is not obvious, and the vibration of the two machines is acceptable in comparison, but when about 20 holes are punched down in a row, the contrast is more obvious, and the use of Dex electric hammer will be easier than the use of Bosch electric hammer.

Question: Can the Vickers 550 jigsaw be retrofitted with a fascia gun, what is the output power of the second DC motor, and what is the noise decibels, thank you. I want to convert it into a fascia gun, is there a physical store in Shanghai.

What's your comparison?

The WORX WU340 is a 26-level with around 900W of power.

GBH2000DRE is a Bosch household 20 grade 650W power, under such parameters, Bosch GBH2000DRE can be as efficient as WU340, is it better for BOSCH?

Punching is not easy, it depends on how you use it. When the hammer is used, it does not need to be pushed forward. Just hold it and push it gently.
