Spyder 12S 4000mah packs

[Jamesppp]

Rob43 said he would like to lighten up a little and try these packs. I bought a 2, 12S pairs to fly in my new 7HV. I am almost finished building the heli. I need to add and program the Skookum 720 FBL controller.

Here is a pic of the 12S stick (not hardwired but both connectors come out the same end of the stick) compared 2 a couple of random 6S, 5000 packs.
They seem very compact and only wei9gh 1200g

Are you guys using velcro on your battery trays? are we supposed to use the foam stuff? The Compass straps are good for the tray if you cut them off??

[Rob43]

That is one slick looking pack. I use velcro on the pack/tray with the Compass straps. It works well for me. I see what you mean about how much smaller they appear to be. The connections up front make for a clean hookup, too. I removed the foam primarily because I thought it was for shipping protection, but that glue they used for attaching it is unreal!

Are you using the Compass straps with no buckle? I thought there were 4 rolled up but there are only 2. I need to cut them down since to cant wrap them around the edge of the battery tray. I have more trays coming

I wish I was ready to go. I would love to fly it in the morning but Im not going to make it. I dont want to rush or Ill frick something up

I tape my battery's to the battery tray (keep the foam) with a good amount of packing tape. They will not move in a crash, and I just buy more battery trays for the battery's.

Rob, I was confused by the original battery tray foam that came with the first batch as well, ended up removing it but that stuff was sticky! It was mental compared to the newer trays.

[Rob43]

Sure was!

Jimmy - I use the stock Compass straps - 2 on each pack - also cut down to fit. No buckle. I like those Scorpion straps but couldn't get the XL size when I was shopping at the time. I bought them for my 6HV since the packs are perched on the plate. However, they aren't long enough for enough overlap for confidence when I run my 40C 6S3000 Sky Lipo packs. The L size should be fine for the 7HV tray, as they are only wrapping one pack to the tray. On my 6HV, they are wrapping two packs side-by-side, so not quite long enough.

Yesterday! Tired or waiting. Gonna get 'em. (1) pack ordered.

I bought a series connector EC5 for them. I soldered a Deans to the ESC....all my junk is Deans...picked up a Deans to EC5 to connect to the series connector

For charging I bought a Parrallel ECG harness, a female Deans to EC5 and a parrallel balance tap harness

T will only be able to charge 1, 12S pack as 2/ 6S in parrallel

My Cellpro 10 S has 2 channels but can only handle a 5S pack on each channel. For 6S packs you have to plug an additional attached balance plu into the second channel

Ill probably only be able to charge at 9 or so amps

Out of all the other 6S packs I have I can only put together 1 other 12S combo from two alike packs bought bat the same time. 6S 5000

The charger was fine when 10S was the the biggest packs I needed and I always just bought pairs af seperate 5S

I feel a charger coming up in the future after I recover from the cash hemmorage of the 7HV build...Rough on a poor boy
