Re: LiPo connections. Good idea or bad?

The red plastic connectors(for bullets), any idea on how to disassemble them? I Have those, made one harness wrong and had to cut through the plastic and buy new ones.

Re: Basic LiPo Charging

What about auto balancing during a ride?
If you have a balance harness connected to all cells, should't all of the cells connected in parallel keep the same voltage?
Maybe the principle is the same when charging?

Re: Hyperion EOS 1420i NET3 14s Balance Charger...

Is it normal that I can only charge with ~8Amps on my 1420i?
Lipo is a Turnigy 10S 5Ah
PSU is 18V@540W

If i split the pack to 5S then the charger ramps up to 19Amps charge current.
So, Im guessing that my problem is that I only have 18V in my PSU?

Re: What charger for bulk charging?

Foret iCharger
Buy this one instead, much better solution and almost for the same prise
I wanted to buy an iCharger 1010b+ but went with this EOS instead!

Re: Going LiPo - Advice Required

Edit: yeah, D-1 with C-1 can be together for parallel balancing without sparks :) I maked a balance harness and now the bad news. Melted one JST when I was connecting two balancers from ONE pack to the same harness(yeah, did not think of course). Maybe I should connect D-1 with C-1 instead, but I'm ...

Re: How far will 1Ah get me?

Yeah not counting on lipos, because I already have them :)
So yeah, around 700US just for lipos/charger/psu/cables/misc
Good news is that you probably can use those things on a bike.

Re: How far will 1Ah get me?

If you can find a brushless motor that can do this on the 800W Elite or the 1000W Lithium, Let me know because I am looking into this too. So far, I have deemed it too expensive to do the upgrade. I think a whole redesign is warranted in this case. http://www.youtube.com/watch?v=48KY9ejvkiQ He fitte...

Re: How far will 1Ah get me?

Good that we get same results here! Cant believe that the manufactures spec is such a lie, a can accept 20% of chart but this is just stupid. The hardware is fine on mine then, guess the brushed motor is crap on it? Next step would be a brushless, any help here? Or maybe I need to start a new thread...

Re: How far will 1Ah get me?

Yeah, Its a stand up and the road goes up and down where I live, its no where near flat, could that be it? Just a bit worried that maybe the motor/controller is faulty. Have to check about watts sunder ride, the watt meter is below deck so its kind of hard to see :) No everything spins easily so no ...

Re: How far will 1Ah get me?

With the stock SLA 12Ah i got around 10km before the voltage is to low and its no fun to drive anymore. When I change to lipo (10Ah)I can go for 11 km before the pack drops to 35V, have not dared to get any lower. Yes, the scooter have chain drive and the peak Amperage is 31A NET WEIGHT: 85 lbs. but...

How far will 1Ah get me?

I'm a bit unsure here reading the scooter manual, it states the the range is about 15 miles but I'm getting around 7 with it original SLA battery? Its a 800W (brushed motor) 36V scooter. My weight is 140 punds. and the speed is 30km/h Now using the turnigy watt meter tells me that the peak power is ...

Re: Going LiPo - Advice Required

Those JST connectors, talk about bad design huh?!
They should use something easier to snap on and less fragile, lika a SATA power connector.

Re: Going LiPo - Advice Required

Btw, what would the cut off voltage be for the nano-tech lipo cells under Load? Is it 3.0V or can I go lower?

Ordered a Hyperion 1420i and a couple of 10s nano-tech turnigy, oh this will be an interesting Christmas!

Re: Going LiPo - Advice Required

Hey, I'm also planning on buying Nano-tech lipo 10s and run as 36V20Ah as 10s4p setup. I'm having lots of questions :) I want to have a very simple charge solution, just plug it in with "one cord" and start charging all the packs together. So leaning towards iCharger 1010b+ The question is how do I ...
