Lipos are fine for the HL.

The only issue with lipos is safety, discharge and cost. If you can afford them, have a dedicated lipo compatible charger and monitor them so they don't discharge too far, you're fine.

Lipos are designed for where weight is a concern, mostly aircraft. Most AC have low voltage warning systems that interupt the motor, warning you they are low before it dies and you crash. Tanks don't need to be light and won't fall out of the sky when batteries run low so they don't have the precautions. A lipo that discharges below a certain voltage (3.2 I believe) it's toast, irretrievably lost. You'll need to set up a low voltage alarm to protect that.

On the other hand, NiCads and NiMH want to be discharged to the bitter end every time.

Lastly, take a second to google lipo fires just to get an idea. They are completely safe when handled properly, but look what happens when they don't. Personally I had a tiny one cell burst in flames in front of me seconds after I pulled it out of my pocket. I still use them, but with a lot more respect.

Thanks ausf, in fact i just bought a charger, "Intelligent digital balance charger", but i am such a FNG on power and currents and all of this, and the operating manual seems like it has been directly translated from chinese to english via google so the words are all messed up. Can you or anyone help me?
I`m trying to charge a 3300mAh, 7.2V NiMH battery pack, and the charger keeps asking me to set: cycle, charge and discharge, what do i put in?

Didn't the charger come with a manual?
The reason I asked is different chargers can require different set ups.

I can't recommend what to do with your charger since neither of us have any idea how it works.

Here's the manual for the charger I use, you may find answers in the tables included. They're pretty useful.

http://manuals.hobbico.com/dtx/dtxp4235-manual.pdf

There's also battery and charger specific forum sections that'll give you answers. I don't know anything more about this stuff than the very specific items I use, so I wouldn't know what to help you with. I use six different batteries and they're all programmed into the charger, I just pick the right one, hit 'start' and keep my eye on it.

Yes it did, heres a quote from the manual: "...you can switched at the same level menu to select the mode by Dec/Inc Key. please refer the etailed flow chart..."
And it goes on like that, i have to consentrate to understand technical english, so this "chinlish" is too complicated for me.

I can help you with this charger .

The type charger you have there is available under various names / manufactures / dealers

and several different configurations , also as a 4 pack charger ( basically 4 of these chargers in one unit ) .

They are good chargers and I use them both , the single and the 4 pack versions .

After you get used to there interface ( check the flow-chart in these manuals ) ,

then they are very easy to use .

They all do share the same interface from IMAXRC :

http://www.imaxrc.com/index.aspx out of China of course

mainly distributed by SKYRC

http://www.skyrc.com/index.php?route...tegory&path=20

and then again just with different labeling and looks of the case from other manufactures

for example HITEC

http://hitecrcd.com/products/charger...harger/product

>>

either this one here ( manual ) :

http://www.skyrc.com/index.php?route...&product_id=13

or that one :

http://www.skyrc.com/index.php?route...&product_id=10

should match the one you have

>>

the HITEC manuals are usually fairly good ,

so here would be the 4x pack version ( individual interface is the same )

http://hitecrcd.com/products/charger...harger/product

which is the SKYRC / IMAX charger

http://www.skyrc.com/index.php?route...0&product_id=8

>>

if you still can't figure it out , let me know and I can write you up some simplified steps .

There is another battery type

Its called A 123 .

they are much better than NIMH and last long , hard to kill too

you do need a special charger

Lipo s are a bit harder to maintain and finicky too
