So i’m just about to do my first build and it’s a Trampa mountainboard with 2x 3500 watt motors. I am going to use the board for heavy off road riding in MTB tracks etc. The only part(s) that i have not ordered yet is the battery. Can’t decide on what would be the best choice. I’ve heard that Li-ion batteries sags more during heavy load and it would be great to get some perspective. I’m currently looking at two options, either 4x 6s 6200 mah lipos (https://hobbyking.com/en_us/zippy-compact-6200mah-6s-40c-lipo-pack-xt90-1.html) these are the ones that trampa recomend. The other option is a 12s5p li-ion from eskating.eu (https://eskating.eu/product/square-12s5p-eskating-electric-mountainboard-battery-samsung-30q/). I have no experiance with lipo balance charging and feel like finding a good charger for the lipos is a bit confusing aswell as it seems more time consuming to deal with lipo batteries.
Anyone has any good input regarding this that could make my choice easier?
