Hello to all!
I've just joined and could do with your help, sorry if this is the wrong section for posting it wont let me post in technical.

I own a scooter rental shop in Lanzarote, summer is here and custom is good. Too good! I'd just bought 24 12v 14ah batteries for my scooters and was intending to buy more until the price went from 30 euro per battery to 55 per battery. Shocking! So as I'm losing trade due to lack of power throughout the day so on to plan B.
My scooters are 36v so 165 euro per scooter is a little excessive. Plan B would be to fast charge them. I have been looking for a faster charger than my current 1.4a and have found the soneil 3610SRF 36v 4.5amp charger. http://www.electricrider.com/chargers/specsheets/3610srf.pdf
The speil seems to reckon there the business and due to the methods used its equivalent to double the ampage in charge. As my batteries are 14ah I figured 4.5 is about the max to go for but at least this would be dividing my current charge time by a third and not hurting them?

As I have my scooters and then a seperate battery charging bay of four chargers plugged into there original scooter ECU's my plan if possible is to split the output from this 1 soneil charger again into the seperate ecus or direct to the batteries themselves. Can I split the connection this way and will it still charge each 36 battery set up at the 4.5amp or is it divied by each battery set?

If anyone has any ideas or has used one of these chargers and rates them please let me know and thanks for any help.

Marc.

hmm...

i don´t know the chargers you mention
but: a acid-battery will not live very long anyway..

maybe - when your scooters are used often (rental shop) - it would be cheaper to invest in better batteries (Fepo4) that will last a lot longer than a acid battery (10times as along as the acid onces)..

you would also not need 14Ah, because:
a 14Ah acid-battery will not give 14Ah at 1C discharge-rate (which i think you could easily have in an scooter).. it will be only 10Ah or lot less

however:
a Fepo4 batterypack lasting over 1000cycles (so some years)
and for charging this: RC-Lipoly

you can charge a 24V battery with 30A current with that charger..
so a 26,4V Fepo4 10Ah battery would be fully charged in something around 20min
