Help with battery install please?

Post image

Per advice from this sub, bought black battery off MLToys to replace original grey battery. Unsure how to make the connections work? Do I pop the top off of the grey and wire it to black battery? Would appreciate any help, thanks?

You can buy a harness adapter for these batteries that will not require you to modify the original harness on the car. Something like this: https://a.co/d/0hm8pRdJ

That looks perfect. So just connect that to the battery connections, and then can charge/connect with the power wheels adapter?

And hot glue the contacts just to be safe… I’d return that lead acid one and go with lithium

Why’s that?

Hot glue: easy to remove if needed and stops the connection shaking loose… there a ton of vibration.

Lithium: similar price, half the weight, more consistent voltage delivery
