A battery upgrade for Razor e300s with LiFePO4

  Hello I'm thinking bout upgrading my e300s to two x LiFePO4 12v 7.5ah batteries.

 Will I be able to make 14 miles on NC streets, one strech about a 1/2 mile or so with an uphill incline? not steep at all.

How will I wire them ? Please show me a drawing.

Thanks in advance,


With an adult rider two 12V 7.5Ah batteries, whether lead-acid or LiFePO4, should provide around a range under the conditions you mentioned of around 6 or 7 miles (1/2 hour ride time at 12 to 14 miles per hour).

For a 14 mile range four 12V 7.5Ah through 9Ah, two 12V 15Ah batteries, or to be on the safe side two 12V 18Ah through 22Ah batteries should do the job.

Our LiFePO4 batteries which are available on this page http://www.electricscooterparts.com/lifepo412v-24vbatteries.html are a direct replacement for the E300 scooter's original batteries.

Our LiFePO4 batteries would be wired exactly as the original lead acid batteries were, which varies depending on the Razor E300 version. We have wiring diagrams for each E300 version which shows how the batteries are wired at this link: http://www.electricscooterparts.com/razore300.html

Please let us know if you have any questions.

How can I tell what version it is ?


The version number is located on the ID tag which looks like this.

The 7th and 8th numbers on the tag are the version number. For example:
03 = Version 3
08 = Version 8
31 = Version 31

The ID tag may be found on the battery charger or scooter. Here is the ID tag locator for all Razor scooter, bike, and go kart models.

Please let us know if you have any questions.
