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 ~(70%) but are waking up and getting around 75- 85% capacity after a few cycles. I've been able to test them at a 30A discharge rate, they are able to hold that rate for close to 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 terminals 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!
These packs have been testing slightly lower than our usual rate therefore we are guaranteeing these packs to hold at least 70% 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"
