This may not be of as much value as you'd like, but I'm using Volt batteries in my Ariens Amp riding mower. It had used 48v lead acid gel cells, but at six hundred American dollars every two years, it was too much money. Florida heat cooks those things and they don't put out much anyway. The Volt half-module is just barely 48v but the mower tolerates a bit less than that, even though a fully charged 48v lead acid pack is in the low fifties. I'm using a high capacity charger probably designed for radio control model use, but it has a HV segment in the programming that accepts my configuration. The top of each Volt module has pin-outs for each cell and my purchase source included the matching cable, giving me a balance connection to the charger. Automatic BMS on the charge cycle with perfect balancing! I had to buy a 96v bundle for the same $600 that a set of lead-acids would have cost and now I have two for the price of one. The seller told me you can't split the module, but a couple of end plates from eBay and some threaded rod and what you can't do, is done. As the mower draws only 20-40 amps, I don't have liquid cooling in place. The maximum current I get from the charger is only 25 amps. I know I won't be cooking the modules. The charger is called the EV Peak A9 and a quick search turns up dozens of purchase options.

I know the Volt batteries are very robust, read where a lot of folks have used them without any BMS. But I really don't want to take any scary chances like that! I would like to use a BMS that only controls the charging & balancing and not the discharge to avoid any current limit issues - I will just employ the controller's LVD. I've been trying to search the evalbum site but it's pretty hard to get any good results where "Volt" is used a lot! I had my mind set on getting some model S packs but still haven't found any priced reasonably locally while gen2 Volt packs are plentiful and much lower priced. My boat (link below) has been running great on a China 96v 100a/h suitcase pack but the fancy bluetooth BMS is limited to 150 amps continuous. Looking at a bigger motor & controller in the 70-100 hp range so likely a higher voltage than my current 96v setup.
