Review: Excelente Atención, agradecido por enviarnos la ultima versión de los BMS Daly.
Review: Dead bms. Chip err. Not even 2 cycles. - Just completed a 72v 40ah pack and properly installing bms by testing each string with a multimeter (professional pack builder 15yrs) It was fine for first ride but half way through the 2nd the bike kept cutting out. Checking Bluetooth i find it no longer registers strings 1-14 and has 6 error messages including collection chip err. This is DOA and is my 3rd daly from desertcart to internally fail due to factory quality. Edit: Daly has reached out and issued a full refund for the defective bms. Still 3 stars for the inconvienence and dead boards.
