How Do I Charge THIS ?

(1/5) > >>

richald:
Just been given a Go Anywhere RC car to fix for next door neighbours kids
but the battery is weird and I am not sure how to charge it - as you can see
it claims to be an 11.1V Lithium-Ion battery but there is no balance cable fitted.

The battery works through two small brass pins, one of which is visible at the
extreme right hand side (the other pin is on the back face in a matching position)
there are + and - markings on the underside.

My Imax B6AC V2 charger will not look at it in either of the Lithium settings
without a balance cable being plugged in.

To add to that, there is a strange error, My charger shows a 3S LiPo as 11.1V
and a 3S Lithium Ion as 10.8V !

Dimensions : Width 75mm approx, Depth 83mm approx, Thickness 22mm approx

Where do I go from here ?  %%

Not sure if you read my original post correctly! - I already have an Imax B6AC V2 charger
and it will not charge any Lithium-Ion or Lipo batteries without a balance lead being plugged in

Would it have it's own charging cradle? Like a cordless drill?


Otherwise is your IMAX set for balance charging? Can it be set for just charge, which might remove the need for a balance lead?

There is a proper charging cradle but I haven't been given that yet - once I have it I will
have to rely on it charge the battery, but in the meantime, I'm still wondering how you can
charge a (probably) 3S battery without any setup to balance the cells - Chinese engineering
is wonderful ain't it? %%

The IMAX instruction manual says the 'balance socket is used for lithium battery charging in all modes'

The modes are : balance charge, charge, fast charge, storage, discharge - but doesn't seem to
explain the difference between 'balance charge' and 'charge'

I will dig a little deeper into the difference if there is any!

I also have the PC based ChargeMaster2.02 software - that may shed a little light !
