New Battery on a A2B Alva+?

Hello everyone,

I have an Alva + and need to replace the battery. Its more than 6 year old. Can I replace it with the battery from the current models (shima or Speed)? Will it be a problem for the motor or controller?

Originally it came with a 36v 13.2ah battery. The ones found i nthe newer models have 36V, 17 Ah.

Thanks!
