Lithium Battery Question
I am thinking about converting my 2020 lance to Lithium batteries. I want to do it as inexpensively as possible. (Battle Born ain't gonna happen) Can anyone tell me what specifications I should look f...

There is also the business about "top balancing" where one cell gets to full and the others then catch up (if I have that right). That needs to be related to just what "full" means to the monitor. If the AH count continues while the other cells catch up (but you don't want the one that got there first to go any higher) that might confuse the heck out of a typical monitor, don't know.
There are two basic approaches to balancing: 1. Passive balancing drains charge from cells having too much charge and dissipates drained energy as heat.
2. Active balancing moves charge from “high cells” to “low cells,” attempting to conserve energy in the battery pack.
Most batteries have "passive" (cheaper), depending on how the bms is set for at what cell voltage this starts at, it's why the dropins needs to be charged at a higher voltage and held longer for the cell to balance.
My Senseboards will start at 3.55vpc but rarely happens, I charge to 14.1v (3.52vpc) and all cells are within 40mv of each other after 4 years. The bonus of actually being able to see all cell voltages within the pack.
