We like cost-effective solutions, especially those that involve a bit of DIY. When we heard about a very inexpensive way to put together a trickle charger with multi-vehicle capabilities, we dove right in. Assuming you have soldering equipment laying around, total cost is under $15.
- Heat Shrink Tube, Multiple Sizes
- Trickle Charger, 12v, 1.3amp output, with overcharge protection
- Quick Disconnect Harness, vehicle side, with fuse (order one per vehicle)
- Quick Disconnect Harness, charger side
We always start by laying out our items on our workspace.
Then its simple cutting and soldering. First, prep all the wires by removing the alligator clips, then separating and stripping the wires. This is the standard red-to-red, black-to-black arrangement. Our charger-side wasn’t colored past the alligator clips, so take care to do one color at a time to avoid confusion.
Soldering is a simple affair. Always remember to add your heat shrink tube first! We then warm up the iron, apply solder, then use our Helping Hands to hold each side. We use a simple 180 degree twist on each side to join the pairs. Apply your iron to the joint, add solder until sufficiently connected, then let the solder cool.
Once finished, we used a lighter to close up the heat shrink tube. Next we would attach the ring terminals to the appropriate points on our vehicle’s battery, then plug in the charger when it is needed. Easy!
