Trying to order another lithium 24V cell balancer

Two years ago I ordered two 24V lithium batteries. Each came with its own BMS (battery management system). Due to being about broke I only ordered one cell balancer for the two batteries - reasoning that I could periodically remove the cell balancer from one battery and install it on the other battery. I hoped that I could simply order another cell balancer when finances improved of course.
Now I have the time and money to order another cell balancer. Cell balancers cost about $120 a couple years ago, as memory serves. But I can not find anything related to a cell balancer at bigbattery.com - that is where I bought the two 24V lithium batteries. Those batteries were originally made to power Fiskar electric cars - as faded memories serve.
Must have ordered the cell balancer from somewhere else. Big Battery shows my order history as simply this: 24V A123 LFP Battery – (a123 8s5p) x 2
Memories could be slightly off, this was August 2020.
Anybody know of a better name for what I am calling a cell balancer? Or a good place to get a cell balancer for a 24V lithium battery? Thanks in advance!

Thanks! Ordered two more since they are so easy to short out.
Man alive, seen inhuman challenges due to the covid disuptions! Was a month late paying a Sheridan, Colorado city stormwater runoff bill for $69. Now they seem to be putting a lien on the house via the next county property tax bill. They are calling it a "special assessment". Won't even let me talk to them. Government always amounts to unaccountable tyranny! Always. Looking for an attorney.
