She’s Come Undone, whoa, whoa ,whoa
Installation is evident if you know what you are doing. The thing works on my bike. A con is the “delamination” of the black xt-60 extension cords. They are unraveling and coming undone. Looking like a real amateur wiring deal.

Great Product, plug and play. Works great.
Great product! Plug and play for adding a second battery. It is a quality product! I did have to purchase another extension because of the placement of my second battery.

Awesome 40A Balancer kit for Lectric & Hailong set up!!!!
Worked like a charm, I ran a Hailong 48V 20Ah battery in parallel with the stock xp4 48V 17.5Ah Battery with no extra wires or parts needed. Followed their YouTube video and got the job done in less than 10 minutes. Comes with a free sticker too. Shout out to Electric All Wheel for helping me get double+ range!!!!!
