How to make powerful rechargeable drill machine using pvc pipe

In this project we learn how to make powerful rechargeable drill machine using pvc pipe easy at home. Here we use BMS charging module. its use for battery over charge protection. and we can charge batteries with any 12v charger. for making this project we need some components.

components:

• 12v gear motor or old drill motor (you can get it form old scratch shop)
• 1.5 inch Tee or 1.75 inch Tee 
• 1.5 inch or 1.75inch  half foot length PVC Pipe (PVC size must match with Tee, if you chose 1.5 inch tee then PVC size also has 1.5 inch)
• 12v BMS Charging module (its protect our batteries to over charge and increase batteries life)
• Push switch or on/off switch
• female connector (its use for connect 12v charger)
• Lethem batteries ( i use 6 batteries for good backup, you can use 3 batteries)
• Plastic box 
• Soldering wire
• Soldering iron

PVC pipe and Tee are total depend on Gear motor. so 1st try to buy gear motor and then buy PVC pipe and tee as per gear motor size. I find old drill motor its fit on 1.5 inch to 1.75 inch PVC Tee. 

Now following these simple steps and make.

• 1st Connect 2 wires with push button and then fit it on half foot PVC pipe.
• 2nd adjust this PVC pipe on plastic box cap you can use power glue for fixing.
• Now connect 2 wires with motor and adjust this drill motor on PVC Tee.
• And now adjust this PVC on Tee. 
• Now take 6 Lethem batteries and make a 3 pear in parallel connection. you can use 3 batteries. i use 6 because i want good backup power.
• And now connect all pears in series and make 12v output cell.
• Now connect BMS circuit with batteries for over charge protection.
• BMS input charging wires connect with female connector.
• And finally adjust all cell and circuit on plastic box.
