Hey guys! Awesome community here! I got a lot of information from this forum but I still need you help.
I run an 10S1P pack from Evolve with 10Ah (some random 6364 Single setup). So far so good. I can drive around 25 to 30km I guess, but after around 10km my voltage sag from the Evolve pack is so frustrating that I feel I am out of battery… but I have still 60% or more left.
I plan to upgrade my battery to an 10S3 or 4P soon. I think 3s is more then enough for my thoughts, but I am little bit scared about the voltage sag again. Special the performance after 10km. What do you guys think? Is the Voltage sagt from 3P to 4P huge? is the extra P worth the money and the weight? How is it when I will upgrade to a double motor setup? I am just not sure would I should do. Please give me some recommendations!
its common knowledge that evolve batteries suffer huge sag. put them under pressure and down they go. You will seriously notice the difference between that and a 30q pack no matter the p but if you want to minimise sag then the higher the amp rating of the battery the better. Definitely 4p minimum especially with dual 63mm motors. There are two different scenarios associated with battery sag.
the battery loses power when fully charged and put under extreme pressure - steep hills etc (evolve style)
the battery drops off in performance once it has reached a low voltage say 30% left.
to me number 1 is sag and number 2 is normal behaviour for liion The higher the p rating will alleviate both these conditions but it really is about the quality of cells and their discharge rate. 30q have been proven time and again but again minimum 4p.
yep fully agree man lipos are way better for sag but didn’t want to confuse the chap. Graphite lipo’s in a usable form will kill it if someone can make them more user friendly. Waiting patiently for Zill to release his new drive. Individual modular p packs that are flight friendly.
