Hello everyone, this article is meant to highlight a safety critical part addition. This affects the: Kaabo Wolf Warrior King GT Pro 72V
This does not include the 60V GT PRO variant of the same model line. This part comes in the form of two fuses for the output side of the battery, two new chargers with enhanced protection technology and four pieces of heat shrink for the connections. We are offering these parts for free to customers who have purchased the Wolf King GT Pro from fluidfreeride.
After a few incidents of fire prompted an investigation from Kaabo, manufacturer of the Wolf Warrior King GT Pro, it has been concluded that it is possible for a short circuit to occur within the controller of the Wolf Warrior King GT Pro. This will cause erratic behavior such as limited performance, turning on and off unprompted, only being able to discharge the battery to 50% before the unit shuts down, clicking or popping while charging, not being able to charge the scooter at all and not being able to turn the scooter on at all. This major short circuit puts the battery into a protection mode via its internal BMS (Battery Management System). Where the problem arises is that customers may attempt to charge the unit while it is connected to the short circuited controller, this resets the BMS which is then immediately reconnected to the short circuited load. This strain (especially after many attempts to charge) can compromise the internal BMS and allow for an uncontrolled flow of current which leads to a thermal runaway of the battery. The resultant fire can be sudden and significant with little warning.
Kaabo has worked with us to provide a parts kit that offers additional protections to the end user. One element of this kit includes two fuses which are placed in line on the positive battery cable. In the event of a controller short circuit, or any other circumstance that would lead to an uncontrolled flow of current, the fuse would blow which would isolate the battery.
The other element of the kit are two new chargers with enhanced protection capabilities from a high-quality manufacturer (XVE), these provide an additional layer of protection on the charging side of the battery further isolating it from any damaging event.
Please see the attached schematic provided by Kaabo:
