Absolutely nothing wrong with the 5P2S configuration of your pack. Nick at EV Battery Center, who passed away over a year ago sold them assembled that way. My pack is 4 years old in that config and I have a 10 module pack in a cart for 3 1/2 years configured just like yours. There are many BGW users with the double configuration from Nick. The only issue with your pack may be that they sent you modules from two different mileage leaf packs. That could cause issues. When you are charging only to 4.08, I wouldn't expect a lot of mileage. You should be charging to about 4.16 and use a good BMS to prevent cell over voltage. The biggest problem with Tech Direct is that they do not disclose the AH of the modules being sold, only that they are at least 75% capacity. Nick tested all of what he sold and stated their AH and also priced them accordingly. I would gurss that most of what they sell are 55AH or less.
