Hi (sorry for my bad english, also I could not find another topic of this problem)
I recently bought an electric mountainboard for riding on the beach. I love it!
I have imported it from China, so it’s not the best quality - but its a joy to ride.
I only have one problem with it… The battery capacity.
It has to be charged for 4 hours after only short period of riding time.
I know that sand is taking a lot of power + my weight of 80kg.
I don’t know much (if anything) about batteries, so that’s why i’m asking you guys…
"Is it possible to add another battery the to skateboard?
I would love to not having to solder new wires to the componens, so I was wondering if it is possible to add a battery and connect it to the charger input of the existing battery. (as seen on the photos) I know this would mean to charging cables.
Will that make i parallel, so I get extra range from the batteries?
The battery i’ve been looking at is an “36v electric scooter battery 36v 16ah 10s5p li-ion” will 2 of those work whith the board though the 3-way wire? (here it is: https://bit.ly/2r7fXZs)
I know it sounds overkill - But trust me, the 11Ah battery is drained in no time.
It’s an electric mountainboard / offroad, and I use it for riding in the forrest and on the beach. Due to sand and uneven terrain, the board has to push so much more.
Right now i’m only getting about 5-8km per charge, and then it has to be charged for 4 hours.
The board sould have plenty of space for mounting more batteries (40cm):
The 3-way wire from ebay is called “Parallel cable” - does that mean that it’s as simple as connecting all 3 batteries (the 2 new + the one already installed) to the 3-way XT60 cable and the board-controller - or do I risk destroying the battery or the board by doing that?
Those cells are very low spec. 3a discharge on 1p (so 15a discharge on 5p). I strongly recommend getting a better battery. Samsung 30q is the standard here.
Essentially that would work as long as every battery is the same, and I mean almost identical. If connected like that each battery must also have its own bms to protect the cells. The charge port must also be connected to each battery or to the main lead going to each battery
Yes a bms is a must have, if there isn’t one the cells can get out of balance and catch fire due to over charge or over discharge.
As for the identical batteries you want them to have the same voltage, amps and similar discharge otherwise will drain slightly quicker than the others (why you need a bms). It should basically be the same cells used in each battery
Yo. Did this work for you? Would like to replicate (different battery type, same idea) on my v3 apsuboard but with just two batteries in order to increase range. My battery craps out about 2 km from my workplace… every day. Good enough otherwise. Well, tires are crap too, topic for another forum.
BATTERY CHEMISTRY SHOULD MATCH AS WELL. And age of cells if possible. If ;not all things perfect, then just charge seperately, equaL volts. There is a thingie I bought, to disregard mostly the differential that I will likely add.
Me personally, I would add backpack battery. Keep board light.
