Yes, there are several different types of low voltage alarms on the market, some of them that show the voltage of each cell and some of them that just give you Red Light Green Light, kind of like go, no-go. You can get them from HobbyKing anywhere from about $3 up to about $10. Just go to Hobby King and look for low-voltage alarm, LVA for short.

Thanks for the info. They do have a good selection.

I found this out the hard way lol. I bought two RC RoardingTop Lipo batts and neither my HL Tiger I or Sherman would take them so I bought two others that do fit, and have to sell the other two, if I can. Whoops measure measure measure!
Oh yeah and add extra room for the wires and plugs please

Instead of trying to sell the batteries, I think you should buy a couple of tanks that have enough room in there to hold the new batteries.

Can the Sabertooth 2x12/25/35 etc run on SBUS or PPM ?
The single connection output types to the Sabertooth.
Can a PPM TGY-iA6BV2RX or any PPM RX use on channel 1(PPM/CH1) PPM output and still use the other output channels 2 to 6 for the RX below to power servo's ?
Any help appreciated.

In regards to the Sabertooth question, you can try and ask Dimension Engineering who make the Sabertooth ESCs:

I have zipped off an email to them already just thought somebody might know .
Some TCB's with a Serial Port 2 can drive the Sabertooth but the 2 I know of Open Panzer and the ASP boards aren't available anymore.
I'm going thru IBU,CLARK,Elmod and others to see if they have the Serial Port 2 output.
Thank you .
PS I found a shop that will have a solution.
This or some version of this will let me through a Y lead go straight to the Sabertooth and on the other side of the Y lead convert PWM to IBUS/SBUS thru a system like this to go to a IBUS/SBUS TCB. .

Start a thread in the main tank forum and you will get more responses to your questions.

OOPS, correction, it's the LiPo batteries that have issues with fire, not Lithium ion.

Welcome aboard.
Lithium ion batteries are considered potentially more dangerous than LiPo batteries because Lion batteries use liquid electrolyte.

Talking about battery and battery charging. I thought I would put my two cents in from experience. I've had NiMH batteries sizzle in a charger (luckily I was in the room) burned my fingers as I pulled them out of the charger. An Alkaline 9V battery blew up that was on my shelf of "dead" batteries. I found something weird on the floor and after some detective work found out it was the internals of the 9 V battery. Fortunately no bad experiences with all my Lipos but I'm always present when they charge and they are stored in those special cases that are supposed to be safe if they ignite (I have my doubts about there safety). I also use a quality charger and charge on metal shelves in case something gets really hot.
