Battery preparation and assembly
Often there are cases when a quality screwdriver ceases to perform its functions due to a weak battery. Throwing such a tool zHAL-KO, it is better to perform alteration of the screwdriver battery. Nickel batteries are usually found in low-cost equipment, as they have poor performance.

Advantages of injection batteries:
- Good current output;
- The power of the screwdriver does not decrease when the battery is discharged;
- The product slowly discharges;
- Charging time is 1-1.5 hours;
- The battery can be recharged without harming the volume.
Injection batteries have a convenient “can” shape with a diameter of 18 mm and a length of 65 mm. To screwdriver translate on a quality battery, high-current banks should be purchased.
For alteration screwdriver battery you need to connect the injection batteries. For this, a special battery compartment is prepared. You can also try to solder the device, but for this you need a weak soldering iron, since such products do not tolerate overheating. Experienced craftsmen to connect DIY battery apply precision welding.
It is important that all banks have the same capacity, otherwise a battery with lower performance will fail faster. To secure the system, it is recommended that injection battery circuit enable plate protection.
To screwdriver translate on the injection battery, you need to disassemble the battery. Terminals from nickel devices are recommended to be left. Excess plastic inside the case should be removed. If there is not enough space, then you will have to abandon the special compartment, and injection battery circuit connect by soldering. The board is glued on top of the battery using double-sided tape.
A thick network cable can be used as a power wire to connect the terminal block. Then, a hole is made in the housing for installing the socket for charging. The terminal block is connected in parallel to DIY battery output from the protection module. The wires are soldered vertically to the protective board.
It is important to fix the block with the terminals to prevent it from slipping (you can insert a regular bamboo skewer). Then the structure is assembled, the bolts are screwed.
It remains to verify the correctness alteration screwdriver on injection batteries on practice. To do this, the battery is connected to the tool and several screws are twisted.
Then the battery is fixed to the screwdriver. If the battery is one, then it can be safely bolted. When it is possible to change the device, then you can use the usual chamber gum.
