Yeah that’s still disturbingly cheap, a good battery of that size should cost at least $135 in materials alone. It’s made of poor quality cells and will have shoddy craftsmanship, you should find a reputable battery builder, I’d offer to do it but I’m not accepting commissions at the moment so I’d go to https://www.duckbatterysystems.com/ or https://esk8life.com/
You won’t hurt your motor but you will not use it at its whole potential.
Yes, it looks like a charger for Liion batteries. Not familiar with this one since I have a smart charger that can charge different chemistries and balance them. But for the battery you want, it seems that it would work.
I see what you mean. Comparing the spec sheets shows that the lg batteries and a fair amount worse your right. Ill probably end up building it myself. Thanks for the advice.
Building your self is a big investment, its at least $200 to $400 for the tools to weld batteries together. Unless you plan on making a lot of batteries I would buy from a known source
Please read the ratings of the battery seller, he is probably deleting bad star ratings and in the good reviews there are also flaws mentioned! And for the rest just like @ZachTetra said.
What if I used 3D printed battery clips and bolts like this person. https://www.thingiverse.com/thing:2595461 I would still need a BMS but all together it would only cost like 150 with cells.
Look for nese or winfly modules instead
Thanks for the suggestion the winfly modules look good. Looking at Samsung 30 q cells. Best price I can find is $5.39 per cell is that a good price? https://www.centralvapors.com/samsung-30q-18650-3000mah-15a-battery/
Maybe go for P42A or 40T, more cell for the same price
The P42A appears to be a fair amount better for only about 5 dollars more in total. Thanks.
Duck battery I recommend
What is a duck battery?
looks like a great option but costs twice as much for the same performance. If I didn’t want to learn to build a battery pack I would go with them.
Fully respect that I don’t have that much time available for a battery build unfortunately
Making batteries is fine, but if you want something that is very durable then you need the right tools and the skill to use them, typically people are not willing to make the investment

I don’t see a battery listed, which is 3rd on the list
Also, I don’t know how well a 3D printed enclosure will hold up. A fiberglass one will be a LOT better. Flipsky ESCs are not the best choice but their motors aren’t too bad.
Thank you for your list that is very helpful. Im building the battery, the parts are further down in the spreadsheet. I have picked out a deck, its on the list. Im an engineering student so I am looking forward to designing the enclosure. Im printing it with PETG which is much stronger than PLA filament but will do thorough testing to make sure everything is safe and will keep my electronics safe. I know the esc is under powered for the motor. I plan on upgrading that down the line, for now im just trying to save a hundred bucks and from my understanding it will still work. I already have cads for the enclosure to make sure everything fits.
You comfy with double king pin trucks? I have a lot more speed wobble with them. I just go slower…
