Hey everyone, some of you may know me from my build thread, where I’ve been learning a lot about what’s good and what’s bad and what is feasible within my rather tight budget and niche-ish needs lol.
Current basics for my board/needs:
Haggy drive setup, with dual-190kv or 170kv motors, and bergmeister 6" wheels (usually).
Hopefully a 36" board like a switchblade but I haven’t sourced a board yet.
Trying to keep it relatively light/compact (for what it is) as it’ll need to be transported in a fairly small boot and/or carried occasionally.
Mostly normal use (roads et al), but I may sometimes be going onto a beach or something similar (with different 8" wheels instead), and so I’ve been told I need a decent amount of Amps to keep me moving even on the firm-packed sand where I live.
On the bright side, where I live only has a few hills, however the ones we have are pretty steep and so decent/reliable braking is definitely a requirement. Something else I was told I need a decent rating for.
Top speed is completely bottom of my list of needs. As long as it moves decently I’ll be happy.
Range / time is more important than speed. I’d rather cruise around for an hour, than blast around for 10 minutes haha.
So I have a few options:
10s5p (something i’ve been offered) - overkill for speed but should fill my needs. Pretty big and heavy though, and probably won’t fit on a 36" board (it was designed for a 40" setup).
8s5p - probably the best configuration for my uses, that I can come up with. Still pretty big and heavy though. ~£300 and 2.4kg.
Turnigy 4s 60C 5000mah - 8s2p setup. Way more discharge (overkill? not sure). Similar weight at 2.3kg, but will fit on the board more easily. Also only £140. Same speed but less range compared to Liion. (Could change to 8s3p setup for £210, but then it’s over 3.5kg)
Turnigy 5s 30C 5000mah - 10s2p setup. Still more discharge rate than liion I think. Same weight etc. £200. More speed than I’d need, but almost the range of the liion. Might be the best option?
New edit: Zippy flightmax 4s 30C 8000mah - 12s1p setup. Actually seems to work out better than the 10s2p setup. Similar price and weight, but a flatter package.
So yeh this is where I am. Playing around with lipo configs to see what I can come up with. I think 6s is a little too low, 8s or 10s seems to be about right, but getting to 3p is suddenly much heavier than i would like.
And after spending a couple of days reading up on batteries and prices and dimensions and voltages and amperages… I needed a sanity check from people on here. It’s very likely I’m missing something obvious, or that my calculations are totally wrong (I’ve been using calc.3dservisas.eu). Where I’m confused is that I’d been recommended LiPo as it was meant to be the better option when it came to size/weight/price/performance… but in order to match the LiIon for range I seem to end up much much heavier, or wasting a bunch of performance on speed I don’t want/need (though I’m not sure if this excess can be used in my favour?)
So yeh, long story short, if anyone has some advice on the most efficient setup for my needs, please do let me know. I’m sure most of this made no sense! Like I said, I needed some guidance and a sanity check, as there’s just so much information to go through and so much of it is out of date or doesn’t apply to my situation.
Thanks to anyone who helps, everyone has already been really helpful on here, it’s been a great community
EDIT - Turns out these packs are all too deep really. Need to stick to 3s or 2s lipo packs. Back to the drawing board!
