"48v" of lead should charge to near 60v.  Depending on chemistry, a 
"56v" lithium pack may charge ok with a "48v" lead charger.  Of course, 
it is crucial not to charge lithium cells beyond their voltage limit.

Re: [EVDL] 12 v desulfator charger/ lithium pack for Zuumer.

[Lawrence Rhodes via EV]

After putting 4 batteries in series in the battery box which will not close the 
Zuumer launches out of the garage but then the batteries sag with my 235 pounds 
on the trike and the best it will do is walk back to the garage under power all 
of 25 feet.  The batteries are so old (2004) while the charger light goes green 
they are done.  Well at least it was enough to test the Zuumer and now I am not 
taking a chance on a stiff Lithium pack. I know the electronics work.  Light, 
horn and a fancy alarm system. Really cool scooter with tilting 
suspension(trike).  https://www.youtube.com/watch?v=UoEqL4l5XBg

However the Lithium pack is at a higher voltage. Like 56 volts. It might be 
possible the 48v lead pack is too low in voltage and is going below the working 
threshold of the Zuumer.  If anyone knows how to get a manual for this vehicle 
I would appreciate it. Even better where to get a set of batteries.  Lawrence

It is Soniel.  They are available at 15 dollars each for a 3 amp charger. Ebay.

"Desulfator" is usually marketing doubletalk. All it means is that the charger 
can apply a higher-than-usual voltage at lower-than-usual current to a very 
dead battery. The doubletalk will make a big deal about their secret 
proprietary pulsed charging algorithms. But, most plain old dumb car battery 
charger consists of nothing but a transformer and rectifier; they inevitably 
deliver over 16v of pulsed charging current into a completely dead battery.

If you don't let your batteries run too dead, you'll never need to "desulfate" 
them anyway. If you *do* run them that dead, nothing is going to recover more 
than a fraction of their original capacity anyway. It's cheaper to buy a new 
battery than pay for some expensive "desulfator". These things are sold mainly 
for car batteries, where even 1% of their original amphour capacity is still 
enough to start the car (3 seconds at 300 amps is only 0.25 amphour).

I have a couple of EV lawnmowers. The chargers that came with them were junk 
(battery killers). I use individual 12v chargers (Ault brand), built for 
electric wheelchairs. The 3 batteries in one are all still good, and the 2 in 
the Robomower are now over 10 years old.

That's exactly what a charger does -- it desulfates.

[EVDL] 12 v desulfator charger

[Lawrence Rhodes via EV]

There used to be a Canadian charger company that had a desulfator function. 
Sol something. Can't remember the name. Can someone remember or recommend 
an inexpensive charger/ desulfator.  I am going to use Genesis 12v 13 ep. 4 in 
series.  I want to use four small chargers.  Lawrence Rhodes Harbor freight has 
the Viking.
