Wasted money counter ?
Do explain?
Capacity meter and modify it to display voltage or just get a voltage meter.
Looking at your old post with your Battery Build. I’ll need 5 of these correct? This will allow me to individual test each battery and allow for easy replacement.
Yes those are very handy for extending the balance wires. The servo tape works well for mounting the batteries and electronics to the deck. For the Vesc mounting I used a Lipo battery tray with Velcro buckle straps
Some other how to info for my build is in this other thread. At the time of this project, I was anti Lipo but after experiencing both worlds, I reverted back to Lipos.
Shouldnt I get a smaller, electrical soldering iron?
Also, in your battery build, you used regular rosin core solder to combine the battery packs correct?
To attach for charging

Is this attached to the E-Switch for an On/Off system?
In route to home now. I’ll post answers in about 30min
I know the Weller soldering iron is good, but i’d still prefer a more flexible solder station for both fine and heavy wire work.

I have an older model than this, which was $30’ish more, but still working well. Seriously some of the best $ spent on DIY tools in a while.
The interchangeable tips - get an extra set until you know which tips you like. Bigger tips for heavy wire, and smaller for the rest of the time. Some good Kester solder (60/40 .05" is my usual preferred).
The hot air is great for re-work and heat shrink!
Look forward to seeing it built and rolling! GL!

I recommended a powerful soldering gun for the heavy soldering that you will be doing. Truth is your really need this and a low wattage soldering station for small stuff. If you try to use a low power soldering tool for heavy wire to connectors and the pads on the bms it will take too long to heat up the wire and the pad and the slower you heat it the more the heat spreads where you don’t want it to. Soldering needs to be done quickly while avoiding cold solder joints. I have soldered heavy wire and even soldered 5.5 bullet connectors together. And I have soldered components on circuit boards so small that I had to use a magnifying glass to see what I was doing.( back in the days when we still used transistors) before SMD even before IC’s. So, you really need both if your gonna really get serious about this stuff. Your low wattage iron needs to be thermostatically controlled. A soldering pencil that just plugs straight into the wall will heat out of control and burn its tip. I have found them to be useless.
This is the worlds best tip cleaner: https://www.amazon.com/Aoyue-Soldering-Cleaner-sponge-needed/dp/B005C789EU/ref=sr_1_3?ie=UTF8&qid=1492121410&sr=8-3&keywords=soldering+brass+sponge
Considering that you can use the hot air gun for heavy soldering, That looks like a good option.
I’m really old school so I have a heavy duty gun and a temp controlled pencil. I bought my low temp soldering station something like 30 years ago. It’s not adjustable but it is temp controlled so it doesn’t burn the tip. I probably should get a new one but hey, this one still works.
The little momentary switches are for the battery meter. If you want to unlock it’s extra features, you will have to ad the switch to the circuit board. I did this so that I could have it display voltage instead of percentage. I detailed the modification in my Li-ion build thread.
For the BMS e-switch, you can use any automotive on/off switch.
@AndrewFox That F2C Station looks like a good deal. I imagine you can turn the heat down and use the air gun for shrink tube as well ?

When you say heavy soldering you mean what? 8 Awg cables can be solded with a normal solder, right?
Man, let’s talk, are you going to use a Bms? Which one? If yes, that Charger is good, If not you will need a charger.
You don’t said nothing about pulleys and belt and motor mount, let us know what are you using. You said at the first time but you changed a lot of things so I’m lost.
Namasaki is a pro in my opinion, so you can trust him, but sometimes you need to go intuition!
What are you missing?
- Enclousure -Something to turn your board On/Off -Remote
Your building is good at the paper, we need to see it on the road!
Even 12ga wires, if you want to have a good quick solder joint you need high power gun. Or else your either gonna have a cold joint or your gonna be heating 2" of wire to solder the end. Soldering bullet connectors requires a lot of heat. The solder pads on the bms require a lot of heat. I used a 260w gun to solder mine and that was difficult enough.
Thank you for the compliment @IsTalo Although, It might not be a good idea to trust ones intuition if they have no experience with this stuff. I trusted my intuition at the first and wasted a lot of money and wound up making a lot of changes. It is however advisable to get multiple opinions not just mine. For example @sl33py made an excellent recommendation for a soldering station that does it all for a very good price.
