A Word About Bottom Balancing

We sometimes have customers asking about a BMS or charger that can do “bottom balancing”.
This is my standard response:

There is no such thing as bottom balancing, at least if you want your cells to survive.

That is a terrible piece of disinformation put forward years back by Jack Rickard and promulgated by social media commentators as
some kind of conspiracy by BMS manufacturers (with possible shady links to the USA government) to defraud the people.
Jack had several battery fires in his time, caused by his own ignorance.
We sell chargers for 1S,4S, 8S and 12S LFP cell packs but you need a BMS to balance the cells.
This usually happens near the top of charge although some systems can balance throughout the cell cycle.
