As the title says I’m looking for batteries for my first esk8.
Looking to run them in 10s
So if you have a battery pack that you didn’t end up using, or you bought the wrong batteries, anything like that let me know what batteries they are and we might figure out a deal.
Also if you have used it and you are not using it anymore, I am interested as well.
As a note: my enclosure can max fit a 10s4p 18650 battery
Did you check the price of members of the forum? For instance https://www.electric-skateboard.builders/t/eu-custom-li-ion-battery-packs/53388?u=rey8801 has fair price. For instance 175 Euro for a 10s3p battery made of 30Q its a good price. Of course if you don’t plan to build one.
I have a 10s3p 30q flex pack with a bestech BMS with switch in the works. €269
I have two Turnigy 5s 5000 mah Lipo batterys which are completely unused. When you put them in series you have a 10s pack.
I have seen that one.
Was just wondering if anyone else has some spare batteries. Is cheaper than letting someone build for me.
@Newby Thank you for the offer but I cannot afford those.
@Mich21050 How much do you want for those?
What about 70€ plus shipping?
Isn’t there a lot of voltage sag with 3p?
Not much, 30qs can technically do 20a
I have a 10s3p Samsung 30Q I notice slightly lower top speed (2-3 kmh) when I have 20% left battery. Acceleration always good. Slightly less but no problem for hill climbing ecc… With my old 10s2p from China was a nightmare at 50% battery
How much range do you have on that battery?
When I put it in http://calc.esk8.today/ it gives me a ridiculous amount of 86km
I mean when you have Samsung 30q 10s and you put 3 in parallel you get triple 3Ah right?
Because 1 samsung 30q is 3Ah.
Am I calculating something wrong here or is it the calculator lol.
@Superflim U would probably get more like 2.5ah x 3. So 7.5ah would be a good figure to go with
Then it is still 72km
Is there something wrong with the calculator or am i putting it in wrong?
I put in: 10s 3p 7.5 Ah
Technically 7.5ah x 36v = 270wh. That should give 27-30km more or less.
Not sure what went wrong there. Basic rule for regular longboard wheels is 8-10wh/km. With 10wh/km more commonly used.
10s 5ah pack would probably ‘yield’ about 4.5ah x 36v = 162wh. +/-16km of range
If I out my battery in the calculator I get 30Km. You set something wrong. Anyhow in reality I get something like 24km I guess… I rode 20km at most and I had 20%left. That being said I ride pretty hard and there are hills in my are. So if you ride around 20-25kmh probably possible to reach 30km
10s3p 30Q si 9Ah battery. 333wh
I know what I did wrong now. I put in the total Ah of the batteries combined instead of 1
Just a forewarning, 5s lipos are huge. I would highly recommend just jumping onto hobbyking.com and getting 5 2s 8000mah FlightMax’s. Grab a cheap bms for charge only and you’ll be sweet. Would set you back about $180aud-ish
i have a 10S4P LG HG2 pm if interested (EU)
Last check if anyone got some!
Otherwise I’ll place the order for one of Pjotrs packs
