Would these batteries work in an original Enertia?

[sunchaser]

Found these on eBay recently and was wondering if they would be compatible with an original 2010 Enertia.  I realize that the bike uses the Valence U1-12XP, but these are also the same chemistry.  Any opinions from the Brammo experts?  Thanks!

Hello Sunchaser,
Using RT's will not function properly/at all..
First: The onboard BMS in a RT is not the same as in a XP. I doubt an RT can communicate with the master BMS.
Second:The XP's have a higher dischargerate then the RT's; XP 80A continue/ 120A peak. RT 30A continue/80A peak. in my opinion the XP's are nearly capable in doing their job: When accelerating the motor will pull over 200Amps from your batteries, when cruising you will need more than 80Amps, so the XP's are allready overstressed most of the time, using RT's will result in overheating the batteries and large voltagedrops.

Hello and thank you for sharing your knowledge once again.  I had a feeling that the batteries wouldn't be compatible, but they're fairly inexpensive on eBay right now.

Oh well, the search for one good U1-12XP continues.

You could rebuild your old ones.

I recently had two Valence U1-12XP batteries rebuilt by a place in California. The output voltage for each was about 16V and they felt lighter than when I sent them out. I told them the old ones were rated for 12.9V, they assured me these rebuilt ones would work. I installed them and now I'm trying to reset my VCU. I'll let you know how they work.

Did they rebuild it with Li-Ion batteries?
The original U1-12XP is build with LiFePO4 batteries..
