How do I modify my 36v LI Battery pack so that I can charge it?

Good morning everyone,

First time builder…building an electric skateboard for my son. I have all the parts and am nearly done but the one dilemna I have is how do I charge my battery pack? There are a million videos on building boards but I have not found any good ones on modifying the pack/wires to be able to plug in a power source.

I’m sure I’m leaving out important information but your help is hugely appreciated.

You will get a charge with the battery pack , like for 36 volt it comes as a set , as per in our country. Or you can buy the charger from Amazon , make sure it’s for the range of battery you bought

It seems like you have a charge and a discharge port , buy the apt battery charger to fit in with the port
