I'm about to order several lipos and 2200ma AA's and need a low voltage cut off for my and my son's Detta SC's but couldn't find one on their site. If not, any recommendations? Gotta be cheap as we'll upgrade to brushless shortly. Probably get the Hobbywing 35a esc.

$5 lipo warning buzzer will do the job

You just have t pay attention - an lva will not shut down like a real lvc will, it just tells you its time to stop.

If you ignore it or don't see/hear it, you'll damage your lipo. No doubt, the lva is the cheaper way to go...

What about a cutoff? I'm not usually that far from it anyway I guess. I just ordered 3 Gensace 2200 lipos for our Detta SC's and two 1800 lipos for the Miniquake and Megatech/Caster cars. Also got 16 2200ma AA's for $22. Seemed too good to pass up for that money.

Yep, they sell one. $8.95 and currently out of stock like usual!

At least you found it... I searched under electronics, batteries, etc. O well.

I just typed "low voltage cutoff" into their search box, was that simple......

Too simple.....doesn't matter anyway, they're out. Is that all I would need to run lipos in our Detta SC's or would there be a problem with the esc?

Thats it.

ESC shouldn't care, volts are just volts whether from a NiMh, lipo, whatever. ESC is rated to 8.4v, so there shouldn't be any probs.

Glad I looked, this is the 1st 2 lines from Tower's tech notes for the SC esc -"This is the Duratrax ESC 7550 Electronic Speed Control with Reverse.
Do NOT use LiPo batteries with this ESC."


However, if i remember correctly, this is only because there's no builtin lvc. In the "Detta thread, I think I remember several saying they'd run lipo with no probs.....

Cool, I'll give it a whirl when I get a lvc. If it smokes it, I have a spare or I'll just order a Turnigy 35a esc and find a BL motor.....

Could also be the connectors and/or gauge of wire not being able to handle the discharge rate of lipo batteries.

Dang, these are still out of stock!! Anyone know of one comparable in price? My son just wants to run lipos in his stock Detta SC as Nimh's just plain suck compared to lipos.... Never thought I'd say that.
