My 3 year old required all of a week worth.  \r\n\r\nif you're using SLA in series make sure to have matching AH ratings so you aren't discharging one battery more than the other.  I recommend spade connectors for attachment to the battery. \r\n\r\nAlso consider you will need to be able to charge these batteries.  I use a 4 flat trailer connector that's tapped into the battery terminal connections. I then use 2 charges 1 that is set for 12v and one set to 6v.  When I plug in the 4 flat each charger is connected to the individual battery. \r\n\r\nFuse - Just spice it in with spade connectors.  \r\n\r\nMost wiring i recommend 12gauge size\r\n\r\nLVC's are available on amazon use them as a trigger and not a load handler.

I don't use drill batteries in my PW's so I can't comment on them too much.  \r\n\r\nGoing 24v board isn't a bad idea to retain the functionality and i believe some operate in the 18-20v range. Only issue is the remote steering motor is also receiving the increased voltage (Causing it to turn  super fast) I'd recommend a buck converter to step the voltage down.  \r\n\r\nWhen buying batteries measure the dimensions so you can make sure they fit.","subreddit_name":"PowerWheelsMods","author":"CPTginger"},{"body":"https://www.amazon.com/Digital-Battery-Low-Voltage-Protection/dp/B07929Y5SZ/ref=mp_s_a_1_1_sspa?dchild=1\u0026amp;keywords=low+voltage+cutoff\u0026amp;qid=1622726804\u0026amp;sr=8-1-spons\u0026amp;psc=1\u0026amp;spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExTUJWWTczSEtVVFBYJmVuY3J5cHRlZElkPUEwODY4MzkzMThLTk45N1hJSllNOCZlbmNyeXB0ZWRBZElkPUEwNjA3MjY5WDVDMkk5SzZQSExVJndpZGdldE5hbWU9c3BfcGhvbmVfc2VhcmNoX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=\r\n\r\n\r\n\r\n\r\nThis is what i used.
