Find the right battery

[HongRC]

Hi all, I just received the Arrma Mojave, but now I can't seem to find a straight answer as to which lipo batteries to run on this unit. I've read that certain battery combinations can burn out the drivetrain. I called Ovonic service and they recommended me their Rebel Series batteries, no answer to my original query.
How much voltage should I run, single or dual battery, and how much mAh? I would appreciate it if you could help me!

https://www.arrmaforum.com/ would probably be a more comprehensive place to ask Mojave-specific questions (basically all of their 6S lineup is interchangeable), but since I have a little experience, maybe I can help.

From Arrma's literature: "4S or 6S Lipo (Hard or soft-case) within dimensions 158 x 48 x 70mm or 6.22 x 1.89 x 2.76 inches"

You will need to look at your ESC connector. There are different versions of the Mojave that come with different electronics (and a different ESC connector). If you have the more common version, it has spectrum electronics and uses their IC5 connector which is backwards compatible to EC5. I would try to find a battery with that connector and not use an adapter if possible.

Batteries have three primary specifications: voltage, capacity, and discharge rate. I'm going to oversimplify this and say voltage is "horsepower." A 6S battery will provide more horespower/top speed than a 4S one. The important thing is that any given motor and any given ESC are designed to work within a specific voltage range. Do not put more than a 6S battery in that Mojave, and do not put less than a 4S battery. Discharge rate is the "C" rating. Think of this as "torque." The higher the C rating, the more punch out of the hole it's going to have. Capacity is just that - how big the battery is - how long of a run time you will have. A 8000mah battery will last twice as long as a 4000mah battery. The capacity in no way affects "horsepower" or "torque."

This is the super high end of the range for what would work for you, but it gives you a starting point. Correct battery dimensions, correct connector, correct voltage. Good discharge rate and capacity. 100-120C is a very, very high performance battery. This particular one is a "smart" battery designed to work with spectrum's smart chargers and if you have the mojave with spectrum electronics and you're anxious about getting into this, I recommend you start with an all-compatible system even if you have to shell out for it a little more. You can modify down the road as you get more comfortable.

I have a Mojave, I run 4s, 2 2s 5200 mah 50c batteries from Lectron Pro, you can run either a single 4s or 2 3s or single 6s Lipo, hope this helps

In theory those should be high performance batteries but they actually fall towards the lower end of the spectrum.


I have a set of these I run in my Kraton EXB,has the same battery tray as the Mojave they come with the proper connector and fit great https://chinahobbyline.com/products...-battery-with-ec5-plug?variant=42646850109654 and I just noticed they are sold out.

This one also fits but just barely it is a tight squeeze into the battery tray but you would want to solder on an EC5 connector https://hobbyking.com/en_us/turnigy-battery-heavy-duty-5000mah-6s-60c-lipo-pack-xt-90.html



But like @95PGTTech said the Arrma forums would be a better place for this question I'm a staff member over there come on by and say hi https://www.arrmaforum.com/threads/what-is-your-rc-lipo-of-choice-in-2022.49890/
