A123 26650 LFP 39.6v 96 cell (Rack Style) LiFePo4 Pack
Here are some more A123 products that we all know and love.
I have two types of these packs:
The most common one is composed of the newer A123 M1B (2.5Ah) cell.
I also have a handful of packs composed of the older A123 M1A(2.3Ah) cell.
These packs are made from 96 A123 26650 cells in 12s8P configuration. This gives you a pack that has a nominal voltage of 39.6v and an original capacity of either 20Ah (M1B cell) or 18.4Ah (M1A cells).
The packs are testing a bit low on the first cycle ~(75%) but are waking up and getting around 85-90% capacity for the second cycle test. I've been able to test them at a 30A discharge rate, they are able to hold that rate for about 3/4 of their capacity, for the last 1/4 the rate slowed from 30A to 20A.
The packs were made to rack mount and the side terminal make connecting these in parallel a breeze. These a fantastic pack for anyone looking for a quick and easy solar powerwall with the safety of LiFePo4 cells!
As usual we are guaranteeing these packs to hold at least 80% of their rated capacity.
Also please be advised that some of the packs have cosmetic damage such as broken plastic bits.
Pack Dimensions are ~30" x ~6.5" x ~2.75"
