I finally got my first Heng Long RC tank today, a Tiger 1 pro. While tinkering I found that my old airsoft gun batteries all fit in the compartment and was curious if they'd be safe to use. They're all NiMH batteries 2 are 8.4v (1500mAh and 1100mAh) and one is 9.6v 1600mAh. I've been googling for the past few hours and haven't found anything as to whether they are safe for the system or not.

The 6.0 HL tanks can be run safely up to 10v. The MFU is rated for up to just over 12v but things tend to get REALLY HOT much past 9v.
I run 8.4 and 9.6 NiMH 4000-5000 mAH batteries. They add weight and in tanks weight is a good thing.

I highly recommend the admiral batteries with tamiya connectors on Motion RC. they last a long time (longer than i usually run the tank), the only con is the recharge time is considerably longer than the stock battery. Unfortunately they are out of stock ATM but when they come back I would recommend you pick one up.

Something you need to know if you use 6.0 with high voltage battery are smoke unit wire will burn on high voltage.Because of cn11 port feed current as battery voltage.And this is the reason heng long launch 6.oS because 6.0S cn11 feed 6V constant. High voltage battery give you hihg speed with no modification. https://www.youtube.com/watch?v=nlaS...Q&index=5&t=0s

Now what we really need is the 6.1S system to be a factory option🤞.

New here, where can I find 8.4/9.6v NiMH batteries that have the same connections the Heng Long Panther uses? The admiral batteries were out of stock when we ordered our first tank today...

We I recommend NiMH batteries it is based on my experience and I understand that MOST tanks are bought by folks that have little to NO r/c background or understanding of how to properly handle and store Lipo batteries. NiCad and NiMH are far and away safer and easier for these people and have none of the issues that can come up rapidly like those of Lipo batteries.
Now if you are an experienced r/c hobbyist and have been using Lipos for years then sure go ahead and use them. You will find though that in the world of r/c tanks you will more often then not be the odd man out. There are even some clubs that will frown heavily on the use of Lipos during events because of the history of r/c tanks catching fire while using them. Seen that a few time too.
The exception: Li-ion batteries are an in between battery not as safe a NiMH but safer for the new r/c hobbyist then Lipos. Unfortunately these still lack the optimum peak performance voltage range option of 9.6. and still require a bit more handling knowledge then NiCad or NiMH batteries.
Dont get me wrong I love Lipo batteries and run them in my planes, cars and trucks, but keep them away from my tanks for the afore mentioned reasons.

Just a friendly warning. At the voltage you are running (3.7 x 3 = 11.1 = ~12 peak volts) you will have rapid heating issues of the MFU and motors greatly reduce their life. If you compound this with higher performance 390 motors you will fry the 6.0 MFU.
Now if you swap over to the 6.1S MFU you should be fine as it has much higher power ratings and can handle the higher volts a bit easier.

The 6.0 MFU IMO is just not worth tinkering with beyond cooling fans. It will ultimately end up costing about the same or more to install and test(?) a cooling system then just buying the upgraded 6.1S system and swapping it in.

Hope I can sk this question in this thread:
In preparation of going outside with my tank I want to buy a couple of the Admiral 3500 Li-ion batteries with Tamiya connectors. I was wondering if I can get by with the standard Heng Long charger? Or is it wise to get a separate charger? If so, will this work: https://www.motionrc.eu/collections/...attery-charger
It only has LiPo in the description, but maybe it can be switched?

SkyRCe3
According to the manual found in the "Support" tab it is ONLY for Lipos.
https://www.motionrc.eu/collections/...er#support-tab
But, If you scroll down in the "Overview" tab they list "LiPo/LiFe/Lilon Cells" so I would assume MotionRC would warranty charging Li-ion. Might be wise to send a message or phone call to MotionRC to verify.

Let us know what they say!

The SkyRCe3 doesn't look like it has adjustable settings but the manual states their maximum amps for either 2s or 3s are well within limits for a Liion and the volts are right at the upper limit.
