Lipo receiver pack?

OK trying to figure out a good lipo receiver battery to use in the 5t. I run lipos in buggies and truggies and it's well woth the extra money to have them wit the regulator. Is their any 1/5 servos out that can take straight lipos like the 7955tg.. rather not use a regulator. Thanks for the help to those who reply!

I've been trying LiPo in my baja and I'm convinced LiPo is a Bad way to go. I think my frustration is because of the LiPo regulator, not the battery.
I've been trying because I shortened my chassis and needed something smaller would still feed enough power to keep my servos.
Go with LiFEpo4. Kent at Killer RC can hook you up. This is by far the most fantastic way to go to power your baja electrical. I don't need a regulator and they are much safer.


The 6.6v 3200mAh LiFePO4 receiver battery pack is $49.

Animal454 runs an unregulated 2 cell lipo, and uses a Rhino steering servo. IMO, it's risky, but Animal454 has gotten away with it so far.

Lipo Powered Receiver/Servo Setup

I've recently researched creating a lipo-powered radio system for my 5T.
What I am going to go with is:
Steering Servo: JR Z9100HVT High Voltage Ultra Torque Servo
Throttle/Brake Servo: JR Z9100HVS High Voltage Ultra Speed Servo
Radio: Spektrum DX3S
Receiver: Spektrum SR3300T (came with radio)

Both servos accept unregulated 2S Lipo battery sources. Their speed and torque numbers are great:
Z9100HVS
Torque: 230 oz/in (2S Li-Po)
Speed: .06 sec/60 (2S Li-Po)
Z9100HVT
Torque: 480 oz/in (2S Li-Po)
Speed: .12 sec/60 (2S Li-Po)

The receiver accepts up to 9.5 volts so you are covered there too.

A big reason I choose the DX3S is the telemetry. The radio will tell me the on-board Lipo's voltage. That was I can monitor for the critial 6.0V threshhold.

I am in the process of determining what battery will physically fit.

Meh, good luck with that. I see two potential problems.
1. The dx3s. No comment.
2. Using a Standard size steering servo in the Baja usually is a bad idea. It works good at first, then goes bad. Many have tried this setup, but ended up going back to large scale steering servo.
