A little extra for just check your lipos but it works good and only take a second for the battery voltage to show up. This works on all lipos that have a regular balance plug, doesn't need to be spektrum branded.

If you're a pilot or driver then you dont want to miss this.

Overview

The Spektrum XBC100 Smart Battery Checker is a must have tool for any pilot or drivers pit box. More than a battery checker, it features a built-in cell balancer, integrated servo tester and driver, and Spektrum Smart battery connectivity.

When used with a Spektrum Smart battery, you will be able to see and adjust many of the settings only available with a Spektrum Smart charger. This includes one connection for balance and battery level checking, and providing records like number of cycles, internal battery temperature and exception reports. You can even adjust Smart battery settings right from the XBC100.

The XBC100 also features a Qualcomm 3.0 USB charge port, giving you an easy way to keep your mobile device and Spektrum Smart Transmitters charged when USB power ports are scarce. Better yet, the XBC100 gives you the ability to better setup and test your models with the built in servo tester! Center and test your servo endpoints easily with the integrated PWM output port.

Finally, all of this is displayed on a full color IPS LCD screen that is designed to be easy to read in direct sunlight and is accessed via a user friendly touch interface.

For those who don't use spektrum smart batteries, what's the advantage over something like this:

Great question. I think the answer is "nothing."

Edit: The spektrum one has the ability to charge your phone via a usb port on the side. A lipo would obviously need to also be plugged into the spektrum unit.

The 30 day price history on the page suggests that it regularly sells for $63, but if you look at the 90 day history it was in the $40 something range. It looks like they jacked up the price for a couple of weeks prior to make this $30 sale appear better than it actually is. If you have check the price history with Keepa you'll see that it originally sold for $40.

I like the fact that it shows all the cell voltages at the same time on a single screen, you don't have to flip from cell to cell, really nice on the bigger lipos like 6s. It also has a servo tester built into it, which I have used more than I would have thought to test and center servos.
I would not advise anyone to buy it at full price unless you are in the spektrum ecosystem and need it to check your smart batteries. But at this price it is not a horrible purchase, but considering that a sub $5 tester can do what most people would need/want, I am sure some people would still consider this a waste of money...

A bit off topic if that's okay, but hopefully someone here can help.

I recently bought Lipo batteries for my sons Arrma 4x4: https://www.arrma-rc.com/en/produ...2V3T1.html

I didn't think he was responsible enough for lipo and was using nimh batteries until now. I think the Lipo batteries blew the ESC. I guess it couldn't handle Lipo's? Can someone recommend a replacement ESC to buy?

TIA

This is likely easier to use than my multi-meter. A deal for a Spektrum product.

Appreciate the input. The servo tester is nice but I already have tools to test/calibrate servos.

The big digital display is nice though...

Get the upgraded brushless 3s capable motor/power upgrade. If you're going to use lipo batteries or want to upgrade to brushless, this is what you want. You don't always need to get spektrum though, just look at the specs of that system and match to whatever brand you prefer.

https://www.arrma-rc.com/en/produ...10005.html

Another option is to try and do a warranty claim. If the car is less than a year old, Arrma/Horizon Hobbies is usually pretty good about replacing items. Just don't tell them you killed it by using a lipo battery.

Thanks. I think I'll hold off if it's going to cost me that much. I think it's almost as much as I paid for the car lol and rather than upgrading, It may make sense just to buy him a new car if just upgrading the ESC won't work. I did just get him an MJX brushless (holiday present).


I'm definitely out of warranty. I think it's close to 3 years old now
