on board charging advice wanted

Just trying to avoid being stuck like I was with the scooter.

I like that the 250w motors can be disengaged so Liz can push me or I can use it as a wheeler, so many options for the money, it does make the 12v charger look very expensive but it seems to be the only one out there in the UK at least, he wants to see the charger and plug that comes with chair to make sure it will be compatible before I order.

There must be a business opportunity for some one there.

End of the day it is just a standard battery you are charging, so any power supply of the right voltage can do it.
I have a cordless air pump that is fitted with a 6V SLA battery. nothing special and lots like it used in alarm systems. I also have a 0V-30V bench PSU for testing stuff and I used that set at around 7V to charge this battery occasionally.
If I had a battery like yours that was 24V, I could use the same PSU but just set the voltage accordingly (probably 28.4V for a 24V battery).

Sounds like the seller is very good. He is concerned you get something that will work right rather than just sending it out. Good on him.

I opted to pay for the chair via Paypal and over 3 interest-free payments to help a bit with the budget, I could have done it with Mobility Plus too but they would have charged about £30 interest, so effectively the Attendance allowance will cover it and the charger too
 
Gave it some thought. Bit out the box but what about a 24v Victron Solar Controller set for lithium. Just switch the solar over to the Victron and let it get on with charging the battery. Would save having to use inverters etc. Just need solar panels in series kicking out more than 30 odd volts. Our panels in parallel and series give 42v @ about 7A. Would certainly charge it up quickly.
 
Possibly but a bit of a sledgehammer to crack a nut on cost grounds I feel as I have none of that, the suggested charger is £52 ish delivered and will plug into a ciggy socket, not sure if it will be okay other than in the

Where as I have an 85w panel and a 100ah battery. which hopefully with a bit of management and only charging on the move it should be ok.

I'm assuming it will be okay plugged into this dash socket.

This would make more sense Powatechnic 12V Cigarette Lighter Socket Charger for Lithium 24V at least if it doesn't perform you can send it back easily. Keep an eye on the socket and make sure it doesn't get hot. It's going to take 5 hours from flat to charge it and use 10A of juice.

Well found I have scoured the net and not found more than the one I had intended to buy.

I was aware of the charge time of 5 hours from flat, but what is flat on a 24v lithium? the range of the smaller battery is 10 miles, if we do more than 2 or 3 I'll be surprised as although I & the chair can do it Liz probably cannot, so it'll get charged from that point not flat.

I did notice in the chairs video a short look at the battery and it says to charge after every use, would I actually have to do that?

I am really crap at this sort of thing so I do appreciate the help given.
 
I thought the idea of Lithium was to not have a memory, like me.
 
They ideally should be Lithium Iron Phosphate batteries rather than just Lithium. It's not going to matter much if you leave them but don't leave them completely flat. Cannot see why they have 13Ah and 10Ah be far simpler just to have the same. Use a 36v battery instead then you can head to Santa Pod for the weekend.
 
10ah is the max for flying so effectively you have 23ah , not sure if you can plug them both in, sadly it is a physical 3 pin plug to remove the batteries to fold the chair down, it's the only thing that lets it down on my scooter you shoved it into a holder with spring-loaded terminals.

No info on Lithium type, but whatever they are it'll be what I have to deal with hey ho.
 
Which technology is it Kev, I thought all that type of scooter uses lithium ion same as in remote controlled cars?

Until Kev clears it up we won’t know but I was under the impression these type of scooters use lI-ion same as rv cars etc. so nothing like lifepo4. It’s not easy to change to a different technology on these as they are custom sizes unlike the more conventional travel scooters same as I have. Saying that there would be nothing stopping someone making their own if they wanted to and have the skills

I won't know until it arrives today or tomorrow, I'll post the info of course.

So not me then :D :D :D
 
Wheels chair has landed, kin heavy bugger, need to get it on the scales it's supposed to be 20kilos plus the batteries @2kilos each.

Looks seriously well made, but the paint has worn off the footrest, and the clip to hold the battery in place is missing, I think it'd stay put on smooth stuff but not on tiles or the rough, I'm just charging the plane battery as it's the smallest then I can try it out.

Once I've checked it all out I'll contact the company and report the issues I've found, not expecting any problems, they have excellent feedback everywhere.
 
I can't find any details of the battery type other than Lithium, did they ever do Lithium only, I thought they were a combination of other elements.

why do they hide useful info in these manuals?
