!! Lets see now, a 48 volt charger as below, with an output 25 to 35 amps. That's what I wanted, at first. But to recharge at a camp ground, or dock from their 110 volt utility or normal voltage might pose some questions. Most circuits are 10, 15 maybe, or 20 if real lucky, then feed that through sometimes 100 ft. of 4/0 extension cord – maybe some other camper making coffee, watching TV – how do you charge up without the gen set we all try to get away from ?? Takes how long to recharge with gas, can't run the genset all night in most camps? Last of all, might that heavy a charge damage the battery pack, materially shorten the pack life --— thought that applied to all battery types.
Point is, that more and higher charge power than most camp plugs -- is not going to be the most cost effective (free?) way to plug and play in public camps.
Note, – Make friends with your local boat dock manager !! At the local lake, they save the closest dock for my visits, and free power as long as I have my 100 ft. of cord, or most of it. Last boat show they gave me, and one other E-boat, a whole dock, and permission to sleep aboard to "monitor" the power cord, also free – except for the beer, and a short cruise.
I have an AODI charger, 14.75 amp by my tester, 15 rated amps. I find that it was $200. well spent. Ramps up, charges well, pulse equalizes, and storage circuits. Actually 5 or 7 distinct levels, and heat controller to prevent damage to either batts. or charger. Three gauges for all charge phases, and LED overall charge timer, that is about all I need so far for basic charge. long term storage is done with a less costly charger, lower power input needs, and that has a pulse conditioner built in, easier to replace fast if needed at about $100. for a purpose built Granite 48 volt unit, at Wal Mart, or by order. When I had only two Batts. to do, I use two Stanley auto 12 volt smaller 10 amp, ones, good price and small size with legible controls, several good check, rehab, test circuit, and more built into a yellow case with cord storage, slick and reasonable price too.
Just making an observation, eh --------- Cal

sounds expensive, I got a 20 amp/24 volt used wheelchair charger unit for $35.00 --- my guess is this unit is 10x that

Hey Ernie,
Vendor alert: We sell an adjustable 48v charger with output between 25 and 35 amps. It also is programmable so if you later want to upgrade to lithium you can change the output voltage and charge curve to meet your needs. I think you'll find it's a cost competitive solution compared to the Elcon. Note that this does not offer balancing for each 12v battery. See link here:
