Are the HS2 batteries compatible with other Juiced Bikes batteries?

Yes, the HyperScrambler 2 must use at least one 52 V / 19.2 Ah battery pack. The 2nd battery pack can use the 52V / 13.0 pack, however we recommend using two 52 V / 19.2 Ah battery packs for optimum performance. Battery packs from other manufactures are not supported.
