Please check if my build makes sense

Hi,

I thought about going for 10s2p battery with these cells, bms(60A version) and charger: https://eu.nkon.nl/rechargeable/18650-size/sony-us18650vtc6.html https://www.aliexpress.com/item/10S-45A-60A-PCM-PCB-BMS-Protection-Circuit-Board-for-36V-Lithium-Battery-Pack-18650-Battery/32843449566.html https://www.aliexpress.com/item/100-240V-DC42V-2A-polymer-lithium-battery-charger-DC-5-5MM-2-1MM-Portable-Charger-EU/32777256395.html

What do you guys think, it’s right bms and charger for such setup?

Then I wonder if I should go for some 2500W 6355 190kv single motor or for two of 1150W 5045 200kv ones (or maybe 140kv?) with 2 VESCs. single: collections/featured-items/products/electric-skateboard-motor-6355-190kv dual: https://www.banggood.com/Racerstar-5045-BRH5045-200KV-6-12S-Brushless-Motor-For-Balancing-Scooter-p-1117661.html?utm_source=google&utm_medium=cpc_ods&utm_campaign=racerstar-sds-all&utm_content=sophia&gclid=Cj0KCQjwn-bWBRDGARIsAPS1svu5HldP6LsWlFF8xgggcO_zySrjQkXG21ZfvbsqS4OqSOLV9qbASi8aAtwIEALw_wcB&cur_warehouse=CN or https://www.banggood.com/Racerstar-5065-BR5065-140KV-6-12S-Brushless-Motor-With-Gear-For-Scooter-p-1110304.html?rmmds=search&cur_warehouse=CN

And kinda want to go for second option but on this calculator: http://esk8.today/2016/12/28/how-far-can-i-ride/#rc I got 18km vs 12km range in favour of single motor. But if I were to go with these dual motors above (less W in 2x5045) won’t I get better range with two small ones? Won’t I improve it even more if I were to go for smaller with 140kv and bigger gear on the motor?

Thank you for your help

200kv is a bit high, but I would go for dual motor because of braking. Not neccessarily because of range or efficiency but two motor braking is so much better than 1 motor braking.

The board isn’t torquing to one side when you slam on the brakes and it isn’t wanting to skid the wheel.
