Upgrade the battery pack I thought it said not check old lead acid.
proprietary plug
i was in jail on this day in lakeland fl. and charged 750 bucks for riding the bike in the thumbnail.
Exactly the problem I'm dealing with on my 24V E-Bike
I have a bike like this. It also has Lead Acid batteries, it goes 40km/h, but after 800-1000m, it drops to like barely 10km/h. Is this because my batteries are bad, or is this just a feature of lead acid batteries. Also, if I upgrade like you, Will this be alot better or only just slightly? I have the same plugs as you, so I will watch all your videos 🙂
An answer to your wonder why your balance charger wasn't outputting it's stated wattage?
I have a similar balance charger, mine can apparently discharge at 2.0 Amps however this is only on certain types of chemistry. Your charger may have a limit to what it can output on Pb? Also as it begins to come to the end of it's charging cycle it will begin to decrease the amount of current flowing to the batteries.
I'm enjoying your Pb -> Li e-bike battery upgrade videos. I'm converting my old mountain bike to a 1000W+ hub motor with a 20AHr lithium battery pack, and I'm going to build a small bike garage with a solar panel roof to keep it charged. We have e-bike power rating laws for street legal use in the US, but unless you're smoking the tires, popping wheelies, and passing police cars, they're pretty much leave you alone. I'm shooting for a 35 MPH LibertyMobile (no license, no insurance, no property taxes, no title, no registration, no gasoline, and easy low cost maintenance). Once built, essentially free urban transportation.
I like the other videos on your channel. You might be my brother from another mother. 🙂
two thoughts. you appear to have connected the lead battery to input of the the turnigey charger difficult to see but something strange about the connections.
A very good attempt well done. Those lead batteries would only give about 8 amps for less than an hour. so it is a very good idea to use lithium.I would want to supply the lithium charger with about 14 volts best of luck.
One thing about these sealed lead aid batteries, they can and will run dry of electrolyte and they an in many situations bounce back just fine if you an open them, refilll them with distilled water and close them back up.
The plates in the batteries are probably sulfated from sitting with a low voltage. It might take a few hard discharge/charge cycles for the batteries to handle a better charge, although they won't be perfect. Looking forward to seeing your conversion. I have a 48V/20Ah SLA powered bike, and was thinking of converting it as well, but I'll need 130 2000mAh batteries, not exactly cheap.
Julian illet. Thanks for your replt. I got one battery pack with the bike it was supposed to be new and the second pack I got from eBay witha receipt for new batteries. I did wonder if the batteries were of good quality.
I have a izip trialz al and it only does 12mph on the flat, short of the 15mph its allowed to do and way short of the 19 mph that USA models do. How is it limited on speed? I have two battery packs of sla and the range seems to be far short of what I expected. BTW, I admit I am baffled by some of the things written on these posts, my late father was an aircraft electrician but passed no knowledge to me. So if anyone answers this can they keep it simple please.
You'd easily see the current drop well below 100ma when the batteries have fully charged. I personally like to charge the batteries separately, but I have time for that chaos, lol.
It may be worth building the charger in to the battery pack for the Lipo upgrade, that way you would always have the charger handy and don't need a ton of balance wires plus the main charging cables.
