48 volt 22 amp or better

[Pheno]

Hey guys Im sorry im not as informed as you all are on here (im trying to learn as much as I can)
I have an e-scooter with a 500 watt brushless hub motor. it runs on 4 - 12 volt 22 amp batteries
the batteries are now dead I can bairly go 2 blocks befor i need to recharge.
can some one tell me if I can convert to lithoium batteries, where to get them and how much they would cost?
if thats to possible can some one tell me where i can get replacement batteries in hamilton ontario or toronto
the best price i have found is about $280.00
thanks for the help.

Well I know you could contact Ping for a lithium option. It will run you a lot more than just replacing the SLA, but if you work out the numbers, it is well worth it.

A Lifepo4 battery will last at the very least 5x as long as SLA, and most likely even longer. Not to mention, if you have 20ah of lithium, you will get about 19.5ah out. With lead if you have 22ah, you will at most get 16ah, and if you are discharging at a higher rate, probably closer to 14ah.

how many charge cycle on your SLA? if you charge them right away and don't pull them too much below the 30% everybody uses for SLA, then they should last 200-400cycles. from what i read.

maybe you should get out a voltmeter and see if you can determine if you have a bad cell in one of your SLA and you can replace the bad battery with a new one.

if you don't know how to use a voltmeter, this is a good time to learn.

a lotta people are adding an extra battery to get to 5 SLA too, for a little more speed.

but go establish with certainty what has happened, the lifepo4 are real money so it is best to already have learned about battery diligence before getting one since that will give you more knowledge of whether you need it or not. especially if it is more a sport and entertainment type vehicle.

A 48v 20 ah pingbattery, (pingbattery.com) would be a good investment. The reason to do it would be a longer range, and less worry about getting the thing on charge right away. If your use is lighter, like ride 5 miles between opportunities to charge, and the first set lasted you quite awhile, then another set of sla's would be the way to go.

Theoretically, if you get 1000 or more full cycles out of a pingbattery the cost per ride is less. But the cost per ride is less important that the cost out of the wallet right now sometimes. I'd say a good rule of thumb would be, if you ride the lead batteries far enough to have the bike slow down a lot at the end of the ride then you'd benefit from lifepo4. The bike slowing a lot is indicating that the slas are getting deep discharges every ride, which ages them faster. But if your ride is shorter, sla's will continue to work fine as long as you can charge right away after every ride.

The best source for sla batteries localy may be a place that sells handicap scooters and wheelchairs. See if local bought is cheaper than shipping from intenet sellers of wheelchair batteries.

Lots of ebay sellers of cheaper lifepo4 batteries than the ones from pingbattery. I'ts a dice throw on the ebay sellers, some send an ok battery, some send absolute crap. They change thier names often to hide if they send crap. Ping has the best reputation so far, my pingbattery has 4500 miles of riding on it and it's acting good as new.
