Convert 3Pin charger to 2Pin charger

Post by SteelBird »

My first tank came with a standard HL charger which is 400mA. It takes about 5 hours to fully charge the stock 1700mA battery. I bought an after market 4500mA NiMH battery to replace the stock one. The stock charger takes around 15 hours to fully charge it. My 2nd tank came with a Li-Ion battery and a 800mA charger which is theoretically double as fast as the first one but it came with a 3Pin connector (as shown in photo) and I cannot use it to charge my NiMH battery.

My question is; is it possible to convert the 3Pin connector to 2Pin connector so I can use it to charge all my batteries?

Greets Steel :wave: ....that charger is exclusively meant for your LION battery...you cannot use it for NIMH and visa versa...you cannot use a NIMH charger for your LION battery or LIPOs ,,,doing so is a recipe for disaster ..on the extreme side ...a fire 8O

Hi Alpha, thanks for your advice about the charger.

Remember my Pantiger is an endless problem? Today I take it and the Leo2 to a new playground; less grass and almost no stone, for performance comparison. The Pantiger with metal tracks, 4:1 gearboxes... of course, wins in all aspects except top speed. But I find new problem on the Pantiger, first, the turret doesn't rotate. After checking, motor is dead. OK, new motor, right? problem solved. second, when I make a sharp turn, the inner track will partially be thrown off the idler (see photo below). I repeat the action again and again to observe how track was thrown off. I found that when I make a sharp turn, because the track (inner) is rather loose and it doesn't move, so it gather the loosen part of the track between the idler and rear most road wheel and push the track outward. So when I steer the tank straight, the idler start moving and ride off the track. (I hope you understand what I describe). Do you have any solution to this issue?

I can think of two things at the moment Steel....one is your idler is toed in towards the hull ...so check your hull for warpage and brace it with a tube or something rigid ...the other is that there is a possibility that your idler is warped or has excess flash somewhere where the teeth of the tracks are going through ...the solution for that would be spinning the idler on a drill...and chase the inner edges with a jewelers file ...careful though...you don't want to taper the edges ...just clean them up a little ;)

I have thought of the first possibility and try to address it with track tensioners but it doesn't seem help anything. I have one more solution, wait for the new Tiger hull to arrive and move everything over.

Tanks compete in slope climbing (seem the Pantiger hard to find a correct position to climb)

If you don't mind me asking...What brand of tracks are you using? Also...are the idlers toed??? either direction is a bad thing...try looking down the length of the tank without the tracks on...check the wheel alignment...there could be just one set that is pushing on the track...and like a deraillier on a bicycle ...will push the track off in that direction

Just watched your video...you have to remember the Leo has a longer wheelbase....it does look like your Pantiger is struggling...but it also looks like the traction got lost when it got sucked into the small ditch in that hill...where the Leo because of it's length tracked over it ;)

Actually, I don't mind you ask any question regarding my tanks. So feel free to ask any question you'd like to know.

Actually, all the after market parts I bought don't have a brand. The vendor advertise them as Mato but when they deliver, they remove every label. Only the 4:1 gearboxes which I bought in Bangkok has a branch Taigen. I also think that the road wheel (inducing the idlers) don't align well and they tend to jump around when you shack them with your hand. I don't have a solution to that. I have tighten them to their max level.

At the first try to climb the hill (didn't record it) the Leopard fail to go up but the Pantiger went up easily. So I record it to prove how the Pantiger would bit the Leo2 in climbing hill. but it proves the opposite. Actually, the way up the hill is very narrow. If you hit the wrong place, you'll fail like what the Pantiger was struggling in the video. The metal tracks of the Pantiger have better traction compared to the plastic tracks of the Leo2 and the Pantiger is also twice heavier than the Leo2 (4.8kg vs 2.6kg). I believe the Leo2 equipped with metal tracks would beat the Pantiger easily.

Hey Steel, as for the charger question, The General is absolutely right that you don't want to mix batteries and chargers for any reason. You'll burn the damn house down! :haha:

I've been using these chargers, they're cheap (so cheap that I bought two), fast, and they charge both nimh and lipos and they've performed great for me for over a year now.

Unfortunately they're out of stock at the moment but they should have more soon. Also, I use the 110 volt US style, but I'm pretty sure they have it in the European plug, too. The point is that you can get a decent, SAFE charger for pretty cheap if you look around. One of these chargers will charge a 3000 mah nimh in about 40 minutes, much better than 5 to 15 hours, eh?

OK LOL...........those Tracks...did you loosen them up before installing them?...Sometimes links bind..
Have had that happen with both my Panthers and my Panzer IV ...to loosen them up...i just squeeze each link...you can actually "feel" them stretch a little ...after that I roll them on the sprocket...then after that I roll them without anything ...it does make a difference...if one link binds that can throw the entire rotation off

That Hill....sounds tricky...but sounds like you had a lot of fun at the park...and that's what counts ;)
