Hello, in advance I really appreciate any assistance I receive! Over the past month I have been researching building my own electric skateboard from scratch and have been quite intimidated haha. As a side project to help build my confidence, I’ve decided to do some upgrades on my two existing store-bought electric skateboards first before I take on building one from scratch.
At the moment I am working on my MotoTec 1600W skateboard (http://www.bigtoysusa.com/mototec1600welectricskateboard.aspx). When originally purchased I could make a 10mile+ trip without recharge, while now I am barely getting 3 miles. The batteries this thing came with are MASSIVE and heavy. Here is a photo of the batteries and the available space (about a foot)
The batteries themselves have basically zero labeling. I have narrowed them down to Kijo batteries, so from china (http://kijobattery.manufacturer.globalsources.com/si/6008848464288/Showroom/3000000149681/ALL/16.htm). Although exact voltage and amperage are unknown. According to website of purchase (which could be incorrect) the batteries in series total 36V 14AH.
I am looking to replace the batteries with some smaller, lighter, and possibly more powerful (good idea?) to get additional speed.
I am looking at a couple of different options, please let me know if these will work: or two of the below run in parallel or these run in parallel
Would these different batteries work? Is there a way to estimate the miles between charge these new batteries could make compared to existing batteries? Lastly, would I be able to use the existing charger to charge these?
