Properly build batteries.

In order to start assembling your new Trinity battery pack you will need some tools which are required for proper assembly. Items needed for assembly, is below and shown in diagram #1.;

• Solder iron, preferably an iron that get about 800 degrees.
• Trinity BIG BORE Battery building jig, Part#TRI30029
• Needle nose pliers
• Trinity Mega Watt Battery Bars, Part#TRI20603, TRI20604 and TRI20605.
• Screw driver
• Dremel, or sanding apparatus like file etc.
• Solder, 60/40 type preferably.



Step 1...
Okay, once all the tools are acquired you can now open your new Trinity battery pack box and get ready to start assembling them. If you do not have Trinity batteries at the current time you can either get them from your local hobby shop or purchase them from Trinity direct online here. The opening of your new Trinity battery pack is shown in diagrams #2, 3 4 and 5.



Step 2...
After the needed items are now open and in reach you can take each cell and lightly sand them with a very non coarse abrasive bit for the dremel or file on each and every positive and negative end of the cells like shown in diagram #6.5.

Note: I recommend you scuffing the edges on a towel or in a place you don’t mind getting dirty. I also would like to recommend a pair of protective goggles for protection of your eyes.



Step 3...
Once the preparation on the ends of the cells is done you can now take a look at how you are going to configure the pack in your remote control vehicle. When you figure out the configuration you can then place the cells in the BIG BORE battery building jig.

Note: make sure the positive and negative ends are going to be connected to each other like as shown in the diagram #7.



Step 4...
Now that you are ready to start soldering your cells together in your Trinity battery building jig, you want to prepare the cells for the Mega Watt battery bars to make soldering easier, so grab the hot iron and apply some solder or tin each end of the top layer of the ends of the cells visible like shown in diagram #7. This will make completing the circuit of the cells with the bars easier when putting the bars on.

The connecting of the battery bars is easy but can sometimes not be done correctly and or over done. When placing the bars on the top of the cells I will apply a dab of solder to each end of the bar using the iron and solder for the next step of applying pressure to the bar when soldering. I usually use a screw driver to apply pressure to the end of each bar I am soldering. You want to make sure the connection is close between the battery bar and cell for best results like shown in diagram#8.

Note: You want to have a solid connection between the battery bar and the cell. A big thing is the shorter the time the iron is on the cell overheating the cell the better it is for the battery pack performance. Basically you don’t want to leave the iron on the cell for too long or it is bad, but do make sure your battery bars have a good connection that wont break from the cell. You must be quick with this step but also accomplish what we are doing and connecting the battery bar to the cell.



Step 5...
After you have continued the steps above till all the cells are attached to each other except for the end two cells. You are almost done and can take the needle nose pliers as suggested tools needed and bend two of the tabs in half for the connection of the positive and negative wires from your speed control and solder them on the packs end. If you are using connectors then solder the wires from the connectors to these ends. This is shown in diagram #9.

Note: Make sure before placing the pack in your vehicle the positive and negative of the cells are connected to each other and obviously the circuit is not completed. Once you have done this and all is good you will want to make sure the pack is neutralized before storing away or charging up for use. I also recommend building a battery pack a day or two before use.



Step 6...
Finally, before placing the battery in storage or charging up, you will want to neutralize the pack in your Trinity DPD discharger like shown in diagram #10. Once the pack is discharged to an even .90 cut-off voltage you can now charge up for use on your charger.

Note: If you are going to store the pack, you should put about 600 seconds charge of 5 amps back into the pack as the pack will slowly discharge its self. Adding this charge will help keep the life of the cells for a longer period of time.
