Mr. Mugen

I am updating my thunder power 1010C charger to charge A123's. These cells are not available to the public from A123 just big companies like B&D. My lhs guy is making a charger for us to try and see if it works using the existing A123 charger for thier 2300's (actually 2200's). I kind of got the jist of what he is doing but wont post about it until it is proven.

Here's a good intro to A123 batteries:

And here's a great charger from FMA that does A123 too:

the batteries in the vpx can you exactly make a battery pack out of it and charge it on the charger the vpx batteries came with?

Beomagi

The original a-123 on a mini (9.9v, quark 66A hiding the third battery). This pushed the ammo 3200kv 666watt motor on a 31t pinion.

Great to hear that mini a123 batteries are finally available!

Characteristics - 3.3v nominal. 60c peak, 30c constant discharge.
cutoff is needed, but it can be easily seen, as the discharge is near constant, then drops like a ton of bricks.


I use an eos 5i for them. Atm, that pack is powering my dremel (modded to run off rc packs instead of measly 700mAh packs...)

i took apart a camcorer battery and had 2 cells like this and they say 7.2v 5.0wh and i dont know what 5.0wh meand and is that the capacity or what

kent_man

Wh is watt hours. Watts = Amperage x Voltage so it's about 694mAh. What are you planning on using the battery for? I doubt it will work for anything RC because it won't be able to discharge quick enough for anything high current, unless you are using is as a rx pack.

rc-junky007

i was gonna use it in my rc18t but i thought it would have a low discharge rate like you said so i dont know

Mr.Mugen does that battery fit in the Detta ST?

Mr. Mugen

Yes it does....with lots of room to spare.

My Feedback: (1)

How are these batteries working for you?

Mr. Mugen

I ran one pack for 2 charges so far. Waiting for my usb cable to come in for the 1010C. Once it gets here I will run them hard.

old thread i know but...any updates?

Mr. Mugen

Yes! They are awesome! I use my 1010C to charge them now. I ran them in mini-t's, detta's, rc18's, m18t, KMI's...and planes so far. They are the best batteries I ran to date. I ordered another charger so I can charge a couple of packs at once. This time I got the 610C. Both are nice chargers.

I love my 610C. How are you fitting them in the m18t? Your measurements would indicate the pack is 38mm wide, and I have had problems fitting anything wider than 34mms.

Mr. Mugen

Sorry. Should have been more clear. I have the M18T pro. It fits with no problem at all. Not sure how the M18T is configured.

domoMKIV

could you post some updated pics of them in the car and maybe of the pack itself?

im pretty interested in going this route on my cars!

Damz

Interesting read. So perhaps lipo will be surpassed sooner rather than later!

Deftones123

I have about 40 charges on my 2 cell a123 pack charging them with a nimh charger, and the the pack is still running strong, I just shut it off when it reaches 1100 mah, never gets hot and seems to work fine, tons of power/punch

Mini_Me

I mean the Pro as well. Pics of your installation would be great!

Damz

LOL!!

I love people like you

Heres the pros debating on whether charging it as a lipo will be .3 of a volt out etc, and then, theres you, who just hooks it up to a nimh charger and gives it hell!!

Nice work [8D]

Deftones123

hey its working and have had no problems at all

Deftones123

its still going strong too, alot of power, never gets hot or anything, screw it, its only a 18 dollar pack

Damz

True. How many volts is each cell? And whats the mah rating on your pack?

Might be a worthy investment!

Deftones123

its a 2 cell pack im running, 1100 mah, comes out of the black and decker vpx power tools battery pack

Deftones123

is amazing in my mini-t, i love it lol so many people say they need to be charged on special chargers, mines fine and even if it dies at 100 charges it was well worth it
