    Help ebco tranz battey bms

    Ho all. Recently bought one. But the battery has been removed from case along with bms. I've wired another battery in that powers it but battery indicator on screen shows 0. Guessing the bms tells the bike the battery info. Anyone know where I can get a bms board from or is there a way round it.

    Was half a sleep still when I wrote it, but my point was if you going to try and test a pack with a standard charger, you have to start from the cells being very low, so even at 2.8 that's 37v. Most peeps never go that low, so testing capacity with a standard charger in never that accurate.

    I say on your test your getting 22ah knowing how ebikes use power, and guessing you don't fully flat the pack, 22ah form a 25ah is a good result

    Hi, you carnt test the capacity of a battery pack that way with a 2a charger, to many factors don't give an accurate result. Couple of quick things are is your charger accurate. As in a 48v battery can fully charge to 54.4v. If yours is only hitting 54.1v then that .3v can drop capacity. Packs...

    bafang 1000w hd trottle problem

    its a really strange one lol i went through the sftware but found nothing to change the throttle settings, and as said the update was just a file sent by the supplyer, quick load to software and hit reprogramme and done.
