It just takes a bit longer to respond because of the steep Lion curve. It will respond in a minute or 2. It does not affect capacity at all. Just a bit different than LA. --Dave Dave Starlight Solar Power SystemsDave > Hello Darryl, > > Quote "You must be careful of LI because if you are

I have about 2 years experience with Prismatic but know of 5 offgrid apps that have been using them for 5 years. They are happy. In general, they are for DIY or hobbyist. The person/owner needs to be very sharp, Very! Most do not use a BMS and top balance charge. The first charge/balance is

I have only limited experience with Lithium batteries. But in that experience, a module of small cylindrical cells will have a higher power, faster charge, and discharge. For the same chemistry, the prism cells will have a little higher energy density. For long cycle life and slow aging, the
