I don't know what sort of car or battery you have, but the LFP batteries will balance without anyone doing anything in particular so long as they are allowed to get to 100% on an AC charger and then left alone for half an hour or so without stopping the charge. They putter around on about 20 watts for half an hour making sure all the cells are in balance, then (if you're watching the app) announce that they're done, and charging stops completely. It's recommended to let the battery do this at least once a week, but in fact it will do it every time it gets to 100%. Mine did it five days in a row once. It never passes up the opportunity.
Since most LFP drivers will be charging to 100% on an AC charger anyway, it just happens. As there's no facility to stop the charge earlier in the app, it's normal behaviour.
NMC batteries are happy being taken up and down between 20% and 80%, and will balance to some extent on an AC charger if the app is set to stop at 80% and the charge isn't stopped. However it's recommended to charge them to 100% once a month on an AC charger and let them balance at that SoC. Then to drive them down to 80% charge the next day because they don't like sitting at a high SoC, something the LFP battery is OK about.
We had a member here a couple of weeks ago driving a second-hand SR which was reporting some weird range figures which seemed very abnormal. The owner of an LR immediately chimed in with "somebody was probably taking it to 100% all the time, not supposed to do that." On further inquiry the true problem appeared to be the opposite, that the car hadn't been taken to 100% nearly often enough and hadn't been able to balance. Once he had done that a few times the range started to look sensible.
The SR has a very flat power curve (or something) which makes it harder for the battery management system to estimate the range, and it needs to balance to get a reasonable range estimate as well as for battery health and long life.
