I have an acton blink S and it gets HORRIBLE range. I mean HORRIBLE. 3-4 miles MAX. I am looking to build a new pack for it.
Here are the requirements for the pack:
6-8 miles of range
Fits in the standard compartment
I am wondering if you guys can help me decide on the cells and which tools I need. I already have a soldering iron. Keep in mind that I am a first timer.
Any help/advice would be appreciated!
This is likely ebike jive. It’s probably a 42 volt 10S pack.
It says 36V on the outside of the pack.
You can’t solder a battery; it has to be welded or use something like NESE cell holders.
It’s highly recommended to buy one, what country are you in?
To build a pack you’re gonna need a spot welder, a lot of patience, and some brain cells.
It’s a lie. Charge it and then put a multimeter on it. Bet it says 42V.
first off, what is this standard compartment size?
Are you just in the US or somewhere like NYC or LA/SoCal or Chicago?
Shipping batteries is better avoided, but possible if it’s not international.
@Skyart is a great battery builder in Oakland.
We build custom electric skateboards, electric skateboard batteries, electric scooter batteries and ebike batteries. Custom high performance safe batteries. Electric skateboard DIY parts like motors, gear drives and more. We also stock a wide variety...
I bet if you contact them, they can hook you up.
I was looking to build the pack myself, just to give it a try.
That’s not recommended. You will probably spend a few months and many hundreds on tools just to make one battery, not including the cost of that battery itself. Plus it’s not an easy task to make a SAFE battery. It’s easy to make a bomb by accident.
If you want to anyway, read this thread:
Batteries are dangerous if not treated right. Nobody want to have a fire at home or lose a board due to a wrong battery design.
This thread should be a summary of clean safe battery packs as well as a place where you can come and ask questions all about how best to build your own pack. Feel free to upload pictures in progress and ask our opinion about the layout, weld quality or what ever you not sure is right done or not.
@moon if I remember right you had a punch of pictures from well made p…
I was also considering taking smaller packs a wiring them up in series. For example 2, 5s battery’s put in series. How many Ah do you think the pack would need to get 6 ish miles of range?
5Ah (= 5000mAh) at 10S (42V)
But if you use the cheapest 5000mAh 5S lipos you can find you might have bad results as they can just puff and die, possibly in a spectacular fire.
You need to get ones with a high enough C rating. Higher the better, and most of the C numbers are exaggerated or straight-up lies, but above 50C or 100C would be best. It’s hard to know for sure since accurate numbers are hard to come by.
And I also recommend a BMS for them
Yep, I know. I have and use hobby grade rc’s with the same lipo’s, so I know the safety. I have experienced puffing before.
Do you think these would work well in the board?
This is five 2S lipos, but the process for two 5S lipos would be similar.
