Just search 18650 on YouTube & eBay

I'm now confused! Transmitter battery or tank? 18650 are bigger than AA and are much higher voltage so won't drop into a transmitter. If you just want rechargable AAs then Duracell work well! Or am l missing something??

From my perspective - Tank.
Its been suggested that I use the '4000' shown above for my old Tiger, and possibly the Challenger2 (both currently have the big SC versions - just different ampage), and the Li-Ion for my T-90. Do you know if the Challenger2 would be able to use the Li-Ion as well ? Ta

It could but you're better off using the larger, higher capacity nimh types. More cost effective.

The tanks will stay lipo I just need to replace transmitter bettery

As far as the tanks themselves go, Better? Non.

Safer? Absolutely!! I have yet to puff, or asplode a LiIon cell pack. I heavily use smallish, light softcase 2200mh LiPo’s, but they are a tad volatile when not treated with due respect. Biggest advantage of LiPo is their huge discharge power, hundreds of Amps, instantly available. A LiIon tops out at 20 amps at most. More than enough for a stock Heng Long, but a tad problematic when it’s an all-metal affair with many modded features like 15w amps ( for sound) bigger smokers, larger motors fitted for the turret rotation and whatnot.

In such a machine, the low-voltage cutoff will quite often spoil the fun with Lithium Ion.

But, Yeah. Get LiIon packs. They are nowadays available up to 3500 mah. I get more than an hour from a 3500mah Admiral LiThium Ion pack ( and it fits the tiny battery bays of the T90 and T72) in a stock HengLong

( check Motionrc for them https://www.motionrc.eu/collections/bat ... -connector )

For transmitters I always go for the Eneloops, because they hold their voltage nicely for months when not using the transmitter. 2000mah Eneloops run for hours in the 2,4ghz transmitters.

There are so many different companies selling them now, its hard to ascertain which is a good seller.
Plus, do you go for anything above 3000mah and 7.2 or 7.4v ?

I am interested in Li-ion batteries but I am wondering what wiring should be done to create a
2S with a charging connector. Do I have to order something with the batteries? Thanks for your help

Tbh. If You do not exàctly know what You’re doing, soldering plugs to LiIons, can become a dangerous affair. You’re better off buying the 3,5amp Admiral packs I suggested, or comparable. They already come with the Tamiya plug that’s needed for stock henglongs, and the balancing wire is also already attached. ( balancing plug is used to charge the pack with the charger that comes with a stock HengLong with Li-Ion)

Again, soldering to the cans of LiIon cells is a delicate affair that needs a vèry high powered soldering pistol- or iron, otherwise the cell will heat up with detrimental results. LiIon is less volatile than LiPo, but remember, the overheating, and bursting in flames of older Samsung laptops was with LiIon batteries!!
