The Turnigy Ultimate 4600 pack has been really good for me. My only complaint is that they are out of stock in the US warehouses right now. There are some 4200 packs in the HK US. I'm holding out for the 4600 again so I will be able to share it with my B54 in the summer
I won't buy SMC packs any more. I've had to throw out several lightly used 1S 1/12 scale packs that were very puffed.

Yeah I guess I'll have to try something else one of these days. My biggest thing is getting quality 4 cell packs. My 4 cell packs have been stellar, so I am hesitant to change

I have those. they are probably the best $35 pack. Mine are a year old with little to no puffing. But... the numbers do not hold up well over time like some of the higher dollar packs like the trinity. But then again, they are $35. you can replace them as needed when the numbers fall off.

I've only used SMC so I don't have anything to compare them to.
1.5 IR is not good. Not when I was getting Trinity RevTechs with .5 per cell.

2.0's are ready for the dumpster.

That depends on how you are charging them and discharging them. Are you both using iChargers? 1.5 IR on an iCharger is very good and as low as you are going to see for the most part on all new packs that are being shipped. The Trinity onroad guys are not even getting packs much better then this, and they are surely not getting anything that's .5 per cell (as read on an iCharger).

Do you have to have a charger that measures IR or can it be done with a multimeter?

+1

I have several Trinity Revtech packs, older orange ones, white carbon & certified packs not one of them has ever gone under 1.3 IR per cell (the best one) on an either of my iChargers doing a 30A D / 25A C cycle charge. Trinity packs are way overrated at their price point. I get much better IR numbers & punch from some of my 2 year old ORCA Infiniti series lipos. Pretty disappointing.

I've seen way to many SMC packs puff. Maybe it was a bad batch and those days are gone, I don't know. But I just can't wrap my head around Danny's comments that "all lipos puff/swell when you run them. You just notice it with ours because our cases fit so tight." (not an exact quote but you the point)

I Danny's defense, tons of people swear by SMC. I'm just not one of them.
Every one of my SMC packs swelled. I've been using Hobbyking's A-Spec and Nano for a few years and not one puffed.

he was getting those numbers after getting the packs to about 120 degs with a 40/40 cycle. 1.5/cell WITHOUT making heat is pretty good.

The B5ML is going together quite smoothly so far, except for the CVAs...... My kit came with 6 pins that all look identical, all of them cause the CVA to bind and become too stiff to ever hope they will loosen up, the holes in the CVA cups seem to be just a gnat's hair too low. What am I missing or are they all tight?

Thanks

Did so already

Problem solved, but the question remains: How did that happen? I tighten and fitted everythin as best as I could...there seems to be no mistake...could I use the wrong slipper hub (not the outer)?



Can you tighten the nut more ?

Look in the ends of the axles. The end that the bone goes in. I have seen a couple kits with axles that have not been fully drilled. One was a CE kit that came with a second set of properly drilled, another kit (FL) I just drilled out the end of the axle a little bit at a time till the binding went away.

The only drivetrain assembly issue I ran into with the Factory Lite was the bearing race on the ball diff outdrive needed to be polished quite a bit as the bearing was way too tight and wouldn't slide down the shaft.
Yup......so I will be visiting the LHS in the morning for new ones. Calling product support to have them replace the bad ones and use those as spares once they arrive in the mail.

In the meantime I will see what can be done with the Dremel.

I would like to know this too; I've hooked up my batteries to my multimeter in the past and wasnt able to get any resistance reading on any of the settings, but voltage readings were fine. I assume I was doing something wrong, but I never looked into it
