While I was thinking where I was going to place the low voltage alarm on my 250, I came across people creating battery cradles which prevent the battery from sliding forward in a crash.
The reason why I was having problem deciding where to place my low voltage alarm was because the balance charge leads for different battery had different lengths. The problem was with the short leads which did not reach the connectors to the low voltage alarm. Therefore, I decided to get a balance lead extension and have the alarm placed in a safer place within the frame.
This is what I came up with, a battery barrier which also double as a location for my low voltage alarm.
