OK. Thank you. Will balance the cost of pulling 3 phase to the charge location vs purchasing a large 1 Phase charger. The single phase chargers look to max out at about 25% - 50% of the available charge amps as 3 phase.
Side note:
Our old fork lift, which is 48 volt, has been on a 120 volt charger for 10-12 years and those batteries have been fine but finally giving out. Not sure of the amps on that charger, but likely only 20-30 amps output.
