Can’t find a thread like this anywhere so i’ll start one.
Post all your battery pack designs, tips, mistakes, questions and everything else that is battery related.
Hopefully this thread will help to prevent unnecessary fires and first time battery builders (also more experienced) from making common (or uncommon) mistakes.
I’ll start: here is my parralel pack design. It prevents the parralel packs from rubbing against each other and shorting.
Maybe as idea people could also give a short information about there materials they used and why in which dimension.
Maybe even with a link where to get legit stuff.
I think here for example about nickel strips or fuse wires. If it goes to cell level fusing for example it could be helpful.
The same with nickel strips. I guess it will not fire up but start to get rusty. So if there is already tested once like from nkon, it would save some money for people who just want to order.
Just did some testing. I took some fish paper from Aliexpress and eu.nkon and tried litting it on fire. It took 16 seconds before the fish paper from Aliexpress got on fire and 41 seconds to lit the fish paper from eu.nkon on fire. My conclusion is that the fish paper from Aliexpress is fake. It also feels much more ruff than the fish paper from eu.nkon. If anyone disagree then please share your thoughts.
Ordered from Ali too some weeks ago.
Guess I’ll need to make that test too when it arrived…it’s not that big money but shitty again to wait for new delivery
Hey all, new to the ESK8 scene and have run into a few hiccups when it comes to making my battery. I want to make my battery custom because its fun to learn about and I want to document the building process and possibly showcase the build / process.
The main problem is that I don’t have a spot welder to make my battery pack as nice as I want it to be. This adds a large cost to my build, and would essentially force me to build a single-drive rather than a double. I thought I found a solution when I found Vruzend selling solder-less battery pack kits, but making a battery pack with those makes the battery pack very wide and will prevent me from using my enclosure of choice.
Kind of split as to how I should go about this. Is the spot welder worth it? Should I find a different enclosure / pack configuration? Is making a custom battery adding too much extra hassle? Any info is appreciated.
Here is my contribution, it is one of those “ask me how I know this”
If you want to squeeze your pack into tight places, make sure you measure twice
And keep your wires routed neatly
Fast shipping source for 22mm heat shrink sleeve is ebay
Sourcing from China cuts the cost in ~half
First I would get some Samsung 30Q instead of the Samsung 25R. They got more capacity and I’m pretty sure they got less voltage sack.
When it comes to the spot welder it depends on if you are going to build more than one battery. If you got a car battery or old microwave you can make it into a spot welder and save a lot of money. It’s going to take some more time and you need to do a lot of research if you build the battery yourself.
I guess you live and the US and there is a lot of people selling esk8 parts. You could get a custom made enclosure but that will cost more than the one from DIYEBOARD.
Thanks for the reply! This helps a lot, especially with the enclosures. I think I’ll pull the trigger on a spot welder to help in future projects. Two follow-up questions though:
Do 30Q’s diminish top speed? Range is more important to me (aiming for 15 - 25 mi) but I’d like a board that goes over 15 mph minimum.
I don’t think it diminishes the top speed. The voltage (10s or 12s) determines the speed. You will definitely have a higher top speed than 15 mph with 10s. You can use this site to see range and speed. http://calc.esk8.today. I don’t know if you are able to get that range with dual motor but with single you should be able to.
Im thinking about putting kapton tape here to prevent the battery from shorting in case a nickel strip gets loose and touches another one or something else happening. Im concerned about if the battery would get too hot? What do you think? Any other ideas?
