Old BMS board stopped working, easy to replace with this one. Works perfect

This killed 2 of my 4 cells in a 12v lipo system. POS. Does NOT Keep cells balanced, waste of money.

Después de 4 meses de uso, a estado trabajando muy bien en mi sistema de 12v 280 amperios. Tienes que usar el voltímetro para saber si está pasando corriente, ya que no cuenta con un monitor digital. Sin embargo es un buen producto, ya que los materiales se ven resistentes.

200AのBMSを100Aで2時間使用したところ、異臭が発生し、電流が遮断しました。 BMSの外観を確認したところ内部の樹脂が溶け出していました。同類の現象はこれで2度目です。最悪の場合ショートによる火災に繋がリ危険です。 高電流を長時間使用する方は値段が高くなりますが、多分、使用電流の3倍くらいの容量のBMSを選んだほうが良いでしょう。これから注文して検証します。
