Is it worth it? no battery

Lipos are fine, not sure why everyone is against them so much. Just get a decent balance charger, and never over or under charge them, and they probably won’t explode and burn down your house.

OT, you said you were in the middle of the north island? Where? I’m Hawkes Bay.

I was going to use a bms to charge them, I’m in Rotorua.

Normally you use 10S/12S 1P >20C Lipos. The problem is that the VESC only have a total voltage LVC. If one cell comes unbalanced the VESC does not detect it… not everytime because the total voltage is over the LVC. When you use 18650 you are going to use at least 3P. these three parallels will balance themself and the pack will stay probably longer healthy .

But the main point to use 18650: LiPo charge cycles: ~1000 LiIon charge cycles: ~1500

If you balance charge, that’s no problem though, it’s always balanced at the beginning. I guess potentially one cell could discharge faster or slower and might cause it or others to be discharged a little more at the end, but that seems pretty unlikely to be an actual problem.

In the quadcopter world, no one monitors indivudual cells and I’ve never heard of it being a problem.

Fair enough maybe on the cycles, but is that really worth the extra cost/effort?

I had the problem that one cell comes unbalanced and now it is always the first cell which reaches below 3.5V… that is annoying because your pack has juice left but because of one cell you are fucked up… But i could be the only one who had this problem.

Another advantage is the “damage resistance”!

Yes really contemplating on buying a cheap spot welder haha

Build yourself a spot welder. Should be cheaper :wink: There is one guy selling a partial adruino kit, just search for “homebrewed spot welders”.

Could I trust my self building one of those haha. They are only like $150 to buy but I guess it will all add up in the end.

Love the board! I wanted a fat tail but for some reason ended up going shorter.

Thanks! Maiden tomorrow all going well!

Is fasttech.com an actual site?? Seems really cheap especially with free shipping around the world

Well I got mine all good, I haven’t tested to see if they’re faulty or anything yet, but they offer a 6 month or 12 month warranty for refund or battery replacement. Pretty some someone else got it from fasttech here, not sure how they went but mine was fine.

It’s a good price! I wondering if aus is as hard as NZ. I might give them an email to see if they can.

Shouldn’t be, but who knows, could be different laws. Mine was smooth sailing, really really quick surprisingly.

Yeah there is shipping times for Australia but not NZ. Dumb you have to register to ask a question though.

did yo check out nkon.nl, good source and they ship overseas, dunno exactly hows in your case?

I got mine from enertion a couple of weeks ago no issues. Space cell 4. In Wellington

What! I messaged him and said it would need to be shipped via sea and would cost another $120. Was yours miss labeled??

I didn’t check. Too excited when it turned up and tore all the packaging off in a frenzy lol

Lol I know another guy on here that got his to but was just labeled skateboard parts.
