I have a Toro Workman MDE, which we use for feeding up the horses and getting around the farm. However the 48V lead acid battery pack is nearly shagged.
The previous owner didn't have the Lister charger for it, and had fitted a Delta-Q 650W charger, which is set correctly for the 8 Trojan T105 6V batteries. The charger has a lithium mode but I'm not too sure if I'd trust it.
I believe it has a Sevcon controller, and the motor would probably top out at around 200-300A if I was going flat out up a hill.
We are on the fence about selling it to try and recoup our purchase price (approx $9k), or double down and convert to lithium.
I've replaced 4 of the 8 batteries however these aren't coping too well with the surrounding dying batteries and I'm sick of adding distilled water twice a week.
I've had quotes for around $4-5k for just a battery pack and BMS but trying to get away with this cheaper if at all possible?
Was thinking of chucking in a dozen or so CALB CA100 cells, or a few Westart NCM cells. That brings the cost to $2500 in batteries alone, is there any BMS and balancer systems out there that would be affordable to go along with this? And a suitable charger?

Thanks for any help
