Hello,
I have this system Cycle Analyst V3, Mxus 3k V3 Motor, KLS7218S Controller and a 72V 26,1 AH battery for the wiring i used this picture from teklektik the differences i use KLS not KLB from Kelly i use this Shunt and i dont have a switch and a Main contaktor. This is because i have the battery in my backpack so in my logic plug in (Plus and Minus) to the external Shunt is On and plug out is Off. To protect my equipment i have build in a 110 A Fuse in the Plus wire and i use a Pre Charge Resistor. I ordered Anti spark XT90 connectors because its the perfect solution only 1 connector plug it in half the way Minus is connected and Plus over the Precharge Resistor wait a few seconds and plug it in all the way and Plus is connected normal. But sadly is the Resistor is only 5.6 Ohm and i cant find connectors like this with more Ohm some here say thay use it on 72 V with no problems some say that will fail sooner or later. To be on the safe side i choose to use the 1.000 Ohm resistor from Kelly and use Xt150 conecctors on Plus and Minus. Now i have to connect Minus than the Precharge Resistor over the not Connectet Plus Xt150 Connector wait 2 Minutes because i dont now how long it takes to precharge with 1.000 Ohm and than connect the Plus Xt150 Connector. And that is not a good solution if you have the battery in your backpack because you have the disconnect and connect often. But the reason why i ask is that im not 100% sure that the controller is going to precharge because to Led´s on the Controller are not on the only thing is that the Cycle Analyst display gets brighter and starts to blink and the Precharge Resistor gets really hot. And now i afraid to plug in the Plus connector after the Precharge so how can i now that the Controller is Precharged and is it normal that the Led´s are off during the precharge ?
Thank you for your help and sorry for my bad english if you dont understand what i mean just ask and i try to explain it.
