Help converting cheap Temu boat power.

[SXFoxstar]

So I bought a cheap Temu boat which was a brilliant little boat which I had a lot of fun with. However I have discovered all 3 battery packs that came with it are not at the full voltage which is why every time I take it out is starts beeping at me.

I am struggling to find these batteries apart from on eBay, according to the label they are Li-ion 7.4v 700mah with the weird sm4p connectors

 

I’ve seen a lot of 360mah batteries to replace them but these were 700 so don’t want to lose the run time. Also with xt60 I could use my sky tc200 to charge it better.

 

Any thoughts on my options to convert, ie what do I do with the four wires to make it just two, can I just solder?

Also can I easily convert the boat to a more readily available two pin by simply soldering the two reds and two blacks together as I assume the only reason it is using four is to make the manufacturing simpler as the servo and motor can be connected separately without soldering?

The boat is trashed and binned so don’t worry about posting.

 

Hope to buy a decent replacement when I can justify it 😜

When you do get another boat try to get a ''hobbygrade type'' that way you can get spares upgrades for them
