XRAY - Model racing cars

Hi,

I would like to know how are you using your standard ESC with the new LiPo 3.7V batteries.

Do you use extra LiPo 7.4V packs or ESC adapted to use 3.7V batteries. All possible information will be very handy.

Cheers

I think most here are using a booster. Like Tekin's TQ Booster or Novak 1 cell booster. Or if you can get a 1 cell esc that would work to.

Anyone have feedback on the newer escs coming unto the market with built in BEC boosters?

Hobbywing has one, as also Speedpassion EX 2.1 PRO.
They are very similar, but Speedpassion has different PCB layout (=wiring is at least different).
From what I've seen, they are fine. One disadvantage, size. To these links cars those ESCs are a bit tight fit.

LRP/Nosram has also 1S compatible ESC. Many of my friends have one, but they have had serious issues with them.
Throttle is very poor in the infield and has a bad feel.
Seems that the new software update has corrected these problems.

Anyway, I would go with the SP one
I have SP GT 2.0 PRO and 2s Life.

Thanks for the feedback. Went with the Speedpassion. I'm also running 13.5 and I read from LRP own comments that the super/spec stock version with high timing will require a new esc that isn't out yet.

The Speedpassion may be big but hopefully not having to run a receiver or booster will equal about the same space used.

Got the speed passion. And though it works as advertised. It really is a HUGE esc. It also required me to turn off the lipo protection to work with the 1 cell. Go figure.

Tekin with 200mah life battery I now use. Works great and clean and tidy without the extra wiring required for a booster

I use the LRP SXX V2 either without the additional RX pack, since the speedo has an internal voltage booster, or I use an LiFe 6.6V 200mah RX pack for some extra runtime.
