Stumble in reverse at slow speeds

One correction for you. Above you said about the lithium that it was lithium ion. It is actually lifpo4. There is actually a big safety difference between the 2. Yes the tech is "newer" and I understand not wanting to go that route for that reason but if you are doing your homework on it make sure you are looking up lifpo4 (wife looked up lithium ion and said hell no. After looking at the difference that lifpo4 has to ion I dropped the PL upgrade in last night)
