i bought a 36 volt 15ah but whenni switced it on it blew the battery fuse did nit even get chance power up the bike or switch on the digital readbout, i have returned it to the seller for refund i thinke the battery was faulty, and niw you have replied wiyh this information i am sure thanks.The ah/capacity can be anything as long as the battery is 36v.
Possibly a battery fault or just a bad fuse. Wrong polarity will ruin a controller if no fuse is install between the pair so I always check battery polarity with a meter, wrong polarity can cause the fuse to blow . Don't always take for granted that polarity is correct, mistakes can be made. It doesn't take much for a mixed up connection on the discharge port.
Ah = more wh which = more range as you know , more range doesn't cause a fuse or controller to blow.
I quite often connect batteries in parallel so will have 29ah or more on 36v or 48v with an inline fuse as protection , mainly as protection for current discharge but also in the past for when using lipo's .
Easy to connect up in error.
i agree but the bike is working fine now with the old battery back on it so no damage i didn't jave a meter to rest polarity, returned the battery waiting for a refund now have to start again in the new year its just such a pain returning things especially when the seller has no clue about the item they are selling.Just be cause the polarity is marked doesn't mean it is correct, only checking with a meter will confirm. It might only be one in a million that is wrong and you might have had the one.
