Hello All,
I am a beginner to RC Crawlers.
I bought the HB - P1802 https://www.amazon.in/gp/product/B017BAE9IA/ref=as_li_tl?ie=UTF8&camp=3638&creative=24630&creativeASIN=B017BAE9IA&linkCode=as2&tag=abitasimon-21&linkId=d33b29b934d256a524d2481d9e672364 (https://www.amazon.in/gp/product/B017BAE9IA/ref=as_li_tl?ie=UTF8&camp=3638&creative=24630&creativeASIN=B017BAE9IA&linkCode=as2&tag=abitasimon-21&linkId=d33b29b934d256a524d2481d9e672364) (blue) model and it works well.
The battery pack came with the model is 4.8V 700mAh NiCd pack.
I wanted to make some spare battery pack with four 1.2V 2800mAh NiMH rechargeable batteries by using battery holder like below,

Will it work to drive the car?

And the connector on the car (male) pic below,

What are these connectors called in online websites?
If the exact one is difficult to find, what other alternative I can by online?
If this is not the right section, please move it wherever it belongs.
Thank you.

Thank you for responding.
I think this is almost similar i want to make.
I dont want to hard solder the batteries, I wanted to use my existing battery re charging unit to recharge the batteries. That why I want to use a battery holder.
Can you tell me the details on that connector you are using? Is that a jumper connector like this https://www.amazon.in/Adraxx-Jumper-Wire-Female-Set/dp/B01LXJ7IUZ/ref=sr_1_21?ie=UTF8&qid=1515842700&sr=8-21&keywords=jumper+cables?
No
It's a standard Servo connector
It's called a jst-sm connector

Hello Folks,
Im trying to build a spare battery pack for my sons RC rock crawler. The current battery pack is a 4.8v 700mAh pack. I want to build a higher capacity pack with rechargeable batteries from reputed brands.
I have come across this thread and am planning to take a similar approach:

Kindly confirm if this approach will work.
Thanks and Regards

Above setup did not work well. Because the batteries were too old and did not have enough juice left. So i used 2 4000mah old tablet batteries in series and run with that.
Thanks for your reply. So if I use a new set of batteries with the batter holder mentioned by you, will it work? I will have to solder the jst-sm connector to the battery holder.

Getting the exact connector may be an issue. Buy jst connector and replace the connector on car as well to jst
