I'm converting my scooter to run on (5) 12 volt 10 ah SLA batteries (up from 3). What's the "best" way to charge a battery bank of this size/type? "Best" being defined as maximizing the life of the SLA batteries with a low cost investment in charging equipment and a simple process. I don't care about the speed of recharge. Overnight is fine. Since I can replace the entire battery bank for about $150, it doesn't seem to warrant dropping a huge amount of charger technology if it doesn't dramatically increase battery life or provide some other benefits. I didn't see any 60 volt chargers at any of the electric scooter parts sites that I could find, and from what I have gleaned from this forum and at battery university, it sounds like you can choose the wrong type of charger or wire things together in a way that could shorten the life of the batteries or even cause a fire/burst battery. Thoughts?

Support V is for Voltage
Well cheapest for you would be a 24v charger, and your existing 36v charger. Best is usually individual 12 v chargers.
Be the pack leader.

the XM-2000 has a 60V charger for $99, but I'd recommend trying to get it from arctic fox because I believe his has lower prices (not sure about the XM-2000 parts though...)
probably not your cheapest option but it sounds like the easiest option
What would be the ideal amp output for a charger being used for a pack of 10 ah batteries? The charger for the XM-2000 suggested above seems to be indicated as having a 4 amp output, but the amp hour rating on the XW-2000's batteries seems to be 34 ah. There's another 60 V charger that's rated as 1.8 amps that X-treme supplies with their 60 volt ATV which seems to use 18 ah batteries. It would seem this would be a closer match for a pack of 10 ah batteries, but I thought I read that .3C was a good rule of thumb for lead acid battery charging. Wouldn't that indicate 3 amps would be ideal? Would it be better to be 1 amp high or 1.2 amps low? Too much to know. Confusion setting in. Brain entering death spiral. Help.
haha sorri, i'm no battery expert... i believe i read somewhere else that the charger amps should be 1/5th of the battery's amps
so like with 10ah batteries i think you want a charger at 2 amps
but I'm really just regurgitating something I read elsewhere
Every battery should have factory specs with the ideal charging parameters. If you get gell cell lead acid it's critical that you follow their recommendations.
XM-3000...
-DC-DC converter replaced with a Dell D220P-01 power supply.
-72V mod
-Expensive bank charger until I come up with something better... Still trying.
