We found a Trike Sun EV3 with petal Assist. The battery is missing. I have done my research and found that the battery has been discontinued. I was wondering how to go about getting a replacement or upgrade for that battery. I can find other individuals that have converted there other bikes with discontinues batteries to a lithium ion battery but can not figure out what to do for my bike, my husband is a mechanic and I think he can figure it out if I get himt he correct parts and in the right direction. Please help!
If so, it looks like it initially was 36V Lead Acid battery, so any 36V LiFePO4 pack (and charger) that can physically be located somewhere on the bike should work. Note that for the same Ah capacity, you will be getting a much lighter and smaller battery pack than the original.

Thank you I will see what I can find. I do have this manual but because the distributor stated that this battery was discontinued I was not sure how to get a replacement. Thank you for your help and I will look to see what I can find with LiFePO4. Thank you again
