Help!
I hope my rep can handle one dumb question!

Ok.

I have a battery pack that is 4.8v 160mAh NiMh

Ok.

I would like to add 2 more cells but they are 4.8v 150mAh

So with this new pack will my charger and car except it ok? Or will I wreck the battery, charger, or the car?

I know I need a beginning electronic class so that doesn't need to be mentioned!

But if it helps I trust this group over all others, and that means something!


This idea is a temp solution until the pack I want to buy is in stock.


thanks,
James

If it is really 160 and 150 mAh it doesn't have enough capacity to move a HOR more than a few feet. What size are the cells? Are you sure it isn't 1600 and 1500 mAh?

In general, for maximum performance, you want to match the mAh but if they are close in mAh and you aren't worried about peak performance then you will be fine. NiMH cells are 1.2V so your 4.8v pack plus 2 cells will give 6v.

he he I never said it was for a HOR. And yeah it's 150 mAh and 160 mAh.

It's for a Micro T.

But thanks for the reply Bruce, I'm going to do it.

They do make a lipo for those already if you didnt know. Not sure if that is the direction you wanna go but just wanted to let you know.

As far as the stock charger be able to charge them......It should but will just take forever.

Cool thanks. And yeah I know about the lipo pack from Losi it also comes with a charger for about $50.00 bucks. That is what I'm waiting for but it won't be released until mid April, Bummer.

And I know, I can always go get another kinda of lipo, the forums are full of people buying this and that, and craming them in but I would need a power source and charger, and that is more then what I want to spend.

Ok. I did it. But then as I was operationing I figured why stop with 2? I did all four! It was actually easier then braking apart the little pack for just 2.

Now my pack is 7.2 volt, PERFECT. Cause I also have a brushless motor and a Tekin speed control so, I think I will fly! I hope.

We will see.
