I’m creating my shopping list for my first build. I’ve seen that the Zippy 10s 4000 mAh batteries are on sale. That’s 148 Wh of energy in just one pack, which seems enough for my intended light usage. However, I’d like to know if it’s advised to use just one pack:
is 25C continuous (100 Amps) enough for a one motor belt driven setup?
i have 2x5s3ah20c in series, mono belt drive. it gave me 6km of range, climbs 13º/23% incline but with huge sag and super slow speed. so for me it’s not enough. if you have hills, buy 2 or 3 of those.
Having a single battery is fine. After all its 10 cells tapped together. It would be the same as 5x2s packs but with more tape in between.
On the other hand, 4A is very low. And 25C is another very low. So you are mixing two very lows together to get a huge low XD. Don’t expect that pack to honour its theoretical 100A discharge without puffing like it just visited an all you can eat buffet
it’s 150 Wh, so using the theoretical 10Wh/km (is this still valid?) I should be able to reach 15 km. Take 10km range to be safe, which would be enough for my light usage goal.
“Nice batteries, but there isn’t 4000 mAh. I can discharge only about 3200-3500 mAh. So, the price can be cheaper” so beware and how will you change them I know its possible but how?
mm - i got barely 4.5km with 6s 5000mAh lipo. I weigh 90kg and the gearing was not probably efficent - im currently making a 2wd board that should go a lot further than that. Also i made diy 18650 packs giving me a 12s12p 35Ah (6x 6s4p packs) - it can take me much further on a mountainboard. A lot is dependant of the drivers height and weight when it comes to range. I think i would get max 6km out of your batteries on my old setup…
That weigh will get you a good result - i dont remember the gearing but 6s with a 280kv motor on 98mm wheels got me up to 30-35km/h. It was a small motor that got pretty toasty after some fast runs. I have figured that i can get over 5km if i drive eco mode - that means not so fast accelerations and never going full speed. Also breaking slowly can also make a difference depending on the esc used
