Just got the pack today and I really like it. It's a breath of fresh air to have a strong, simple battery that just plain works. My old LiPo pack with its BMS used to cut off on my all the time if I gave it too much throttle. This pack just powers right through! The one thing I would caution is that if you are putting it in a rear rack bag, lay the pack down so the cells are vertical. I tried standing it up as shown in the product picture and this puts too much stress on the bottom/outer two batteries and they come unwelded in no time (happened on my first ride on a bumpy trail). I fixed it by simply soldering the jumpers back on carefully but not all customers will have the expertise to do this. So be advised: don't put stress on those cells on the corners of the triangle!
