    Can electric scooter controller specs be found on outside of controller casing?

    I get your drift Flippy, and you are right again of course. My prime limitation, as I mentioned earlier, is that my personal health issues and restricted ambulatory abilities (which continue to regress) may deny me the ability to use my scooter altogether not so far down the pike. Otherwise...

    Can electric scooter controller specs be found on outside of controller casing?

    Thank you sincerely Flippy for your comprehensive reply. You've pretty well convinced me, as I suspected all along, that most if not all of the lower cost ebay/Chinese made Lifepo4 batteries are not going to "cut the mustard", especially over time. That being said, however, the price range...

    Can electric scooter controller specs be found on outside of controller casing?

    Okay Flippy, you've got my undivided attention. Thanks for your comments, and I take it from your avatar that you have a distinct interest and knowledge of Lithium batteries......to the contrary, I have virtually none. I'm not even sure what you meant by your last comment; "...should be able to...

    Can electric scooter controller specs be found on outside of controller casing?

    I think I understand you to say that lifepo4 batteries are good for storing energy but inappropriate for use with e-bikes or e-scooters. If my understanding is correct, then that's the first time I've heard anyone make that assertion. Do have some further information that you could provide...

    Can electric scooter controller specs be found on outside of controller casing?

    Just wanted to let you see the seller's reply when I asked him about your comment above that you made about the battery's amperage........"The battery can handle 30Amps and 60Amps peak current." Unless I hear some other contrary comments on this post, I think I'll go ahead and take a bit of a...

    Can electric scooter controller specs be found on outside of controller casing?

    I asked a seller (of a 48v 15ah LifePo4 battery for 700w ebike) if he had any comments on the compatibility of his battery for my mobility scooter which currently uses (4) 12v 20ah sla batteries for it's 48v system with 800w motor. His reply was to request the specifications on my controller...

    Is it OK to replace 40ah scooter batteries with 35ah?

    I've have previously received some very good advice from this forum on replacing my four SLA 12v 20ah batteries with Lifepo4's for powering my 15mph, three-wheeled, 800W Chinese mobility scooter. The essence has been that if I wish to switch to Lithium batteries I should get at least a 15ah...

    Is it OK to replace 40ah scooter batteries with 35ah?

    I owe this forum an apology..... :oops: I just realized that I asked basically the same questions in a previous post that I asked in this post. The truth of the matter is that I'm 73 years old and the short term memory has gone to hell in a handbasket, so I had completely forgotten about...

    Is it OK to replace 40ah scooter batteries with 35ah?

    I have a 48v (4 x 12v 20 ah) SLA power bank for my three-wheeled electric mobility scooter (Chinese made, no brand). I think I'd like to get a LifePo4 battery at replacement time (which is getting close) and I would like to know if matching the 20 ah ampere of my existing system is essential...

    Is it OK to replace 40ah scooter batteries with 35ah?

    You know, this is a good point. I happen to have a three-wheeled (fast) mobility scooter myself, and I too will soon need to replace my four 12v 20ah batteries as well. The LifePo4 option is initially much more expensive, as you pointed out, but in the long run it may even be a bit less...

    Is it OK to replace 40ah scooter batteries with 35ah?

    You are correct. They should be deep cycle batteries. I am not buying them however, my neighbor is, so he'll have to decide what he's willing to pay. Thanks for your link/suggestion as well. I'll be sure to show it to him.

    Is it OK to replace 40ah scooter batteries with 35ah?

    Got it!.....Lower ah ratings, probably less lead and longevity (and range), and no batteries that aren't rated for EV's......Thanks so much

    Sorry, but there are no data sheets for either the old batteries or the one's for sale, but thanks for your suggestion and the info as well.

    Is it OK to replace 40ah scooter batteries with 35ah?

    My neighbor has a Pride Victory Sport 4 wheel mobility scooter that needs some new batteries. His original batteries are (2) 12v 40ah (AGM/SLA), but in attempting to shop for him online I see that the prices are much lower for 35ah batteries, and they quite often claim to be replacement for...

    Is an 8ah 24v charger needed or is 5ah 24v charger OK?

    Hey mate....thanks for your comments. The dealer didn't recommend the new charger, their cust. svc. agent just relayed the recommendation from the battery manufacturer rep they spoke with and who knew only my charger amp rating and nothing else. I kinda had the same impression as you expressed...

    Is an 8ah 24v charger needed or is 5ah 24v charger OK?

    I don't have a multimeter. I don't know the watt rating of my existing charger(not cited anywhere on surface of the charger), and I haven't yet purchased an 8 amp charger, so I can't give you the watt rating on it either. The batteries are 12v 50ah gel SLA batteries and a tech from my...

    Is an 8ah 24v charger needed or is 5ah 24v charger OK?

    That was my first thought when I heard the recommendation. Unless I learn differently, that's what I'm accepting and keeping my $100 Thanks for your input.

    Is an 8ah 24v charger needed or is 5ah 24v charger OK?

    My bad....I apologize for the misstatement.....it should have been amps, not ah that I used....stupid is as stupid does, or something like that. I think I watched the Forest Gump movie too many times.

    Is an 8ah 24v charger needed or is 5ah 24v charger OK?

    I was fortunate enough to have someone donate an electric wheelchair to me this past year, but I've also recently had an unfortunate experience in purchasing two supposedly excellent quality, U.S.made, gel batteries, but they went south on me almost immediately. The "gooder" news is that my...
