I was wondering what size battery balancer is in the RX pro?

Thinking about purchasing a Rize RX Pro

The delivery date on extra batteries is very long and I'd like to just grab a 20ah from my other bike and put it on the Pro.

Any body know the Amperage of the balancer in the RX Pro? 30A? 35A? 40A?

Most battery balancers are in the .1amp to 1amp range.

Hey - I have an RX and just added a 25Ah 52V secondary battery. My battery has a 30Amp BMS and it works fine (2nd battery only, rize original only, & both simultaneously).

@jimbocrimbo, if you added a 25Ah 52V secondary battery, it isn't from Rize, right? They don't sell one with that much capacity (they only offer a 15Ah 52V add-on battery). So, where did you get your secondary battery, and in particular where did you find the plug for the battery socket at the base of the downtube? That plug seems to be proprietary...

Hey @wanders - you are correct. I ordered from @Jenny Mao and they supplied an alternate connector that is the same fit.
I'm overdue to write up the install and initial thoughts (I wrote out the whole thing, saved it as a draft on here and lost it 😭).

I'll see if I can get the pictures back on here and do a quick write up this evening. But TLDR - battery works great, install was easy (for me) and would recommend. Thanks @Jenny Mao

Edit: Just posted a quick install/review: https://electricbikereview.com/forums/threads/rize-rx-2021-52v-12ah-secondary-battery-upgrade.51789/
I'll update as soon as I can but LMK if any questions.
