Turnigy Watt Meter vent

Would the Turnigy Watt Meter succomb to a premature death if I sealed off the vent on the underside of the unit? Has anyone tried running a sealed unit?

Re: The importance of good quality torque plates

so maybe I should just finger tighten the pinch from now on..? I have trouble seeing how the pinch could've loosened the piece from the epoxy in the cove of the dropout.. since it is thick and doesn't have a slot. I noticed this when I found my wheel leaning to this side of the frame, meaning the p...

First, a pinch dropout should not be glued in the mobile area. I see that when you tighten the pinch, the glued surface has to move.

I suspect this is the main problem.

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

neptronix, I remember reading about issues when using TVC but can't remember what they are off-hand, so I simply avoid it and use TCS instead. TCS 95% will get you ~4.13v - 4.14v. I believe you can set in 1% increments via software only. Otherwise 5% increments via the charger. Also don't use the st...

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

cwah, Sorry, It isn't literally called "passive mode". Press the mode button until you reach "Balancer Mode" Just charge/discharge in lipo mode and monitor closely. Doing so will reveal any bad cells. From what I've read, it isn't worth the hassle, or the return shipping cost, to exchange lipo from ...

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

First off, I don't know how high the cell voltage will terminate at TCS 75%. What I do know though, is that at 40% TCS, the cell voltages terminate at ~3.85-3.86v. So at TCS 75% your probably looking at a significantly higher termination voltage. Disregard the % capacity values computed by the wacky...

Re: resistor on 100v lipo pack

Why is everyone using 2 switches? All you need is one, with the precharge resistor wired in parallel. Flip the switch one way (the normally open position) to connect only the precharge circuit, flip it the other way and it shorts out the resistor, closing the primary circuit. Am I overlooking somet...

It would be cool if you could include a feature to switch on a booster pack.

Re: Kickstand

A suggestion on how to keep the stand securely mounted to the bike (eg: to prevent it from rotating) without having to clamp it down with such force that you risk deforming the frame: Slather a layer of high-strength epoxy (such as JB-Weld) onto the top pad of the stand and then cover it with a dur...

Well, if you don't have the manual, do a google search with your model #. Surely there must be a site revealing the specific features of your laptop.

Re: Is one torque arm enough?

i think epoxy is a really great thing. if used properly and if you got the right stuff. there must be a reason why today many parts in cars are glued and not bolted or welded. glueing is superior to welding/bolting to some degrees and to some it's vice versa. it*s as simple as this.

Another interesting option. Please post your impressions when you get it mounted.
