    18AH, 48v, SLA, max charge rate?

    I have 4 12V 18AH SLA's wired together for 48v and there are times when I need a faster charge. I'm using a 2.5A charger now and wanted to add another to that for 5A total charge rate. So I guess I'm asking 2 questions here...what's the max charge rate for this battery (in case I want to add...

    Throttle wiring

    I had to add to/reposition some things on my handlebars so I could get more on them and after putting things back together I get no throttle. I tried the throttle just before I did this and all was well. when I moved the thumb throttle to put it on the other side, I tried to do it without...

    Fuse individual cells or not?

    Are there sometimes reasons when it's more advisable to fuse individually and times it's not so necessary? Or is it a good idea all the time? Odds of problem without? Why not just the one main fuse? Or what will a the main fuse not protect? I also wanted to mention what I'm doing so you all can...

    2 chargers in paralel...cool?

    I can get 2X2a 36V (42v) chargers for less than $20, while the 4a is $50. I already have a 2a, so any reason I can't buy another (they should be exactly the same charger) and put them together in parallel to make a 4a charger? Can I charge this 36v around 26AH Li-ion battery, at 4a without...

    sending a private message

    I just sent a private message and it shows as in my Outbox, not in the Inbox, but no option that I see to send it, and no mention if there is a lag/if it will go out automatically or what? Kind of confusing. Do I just wait and it will send or do I have to do something manually to make that...

    couple of battery pack questions.

    Is the full battery pack voltage calculated using the 18650 fully charged 4.22v or the 3.7v value? What is roughly the maximum voltage a 1000w/48v hub motor can handle? Can't seem to find how many nominal 2100mah, 18650's I'll need for an 18ah/48v pack so hopefully those numbers will give me...

    Tire sizing to rim...something seems wrong.

    This might go better with bicycle forum but since I'm registered here, I'll give it a shot. The tire on my ebike trailer is shot due to my spare cheap ebay tube popping immediately after replacing it on the road, and my having to drive it with no air to get home (that's mostly a warning about...

    Help making mismatched throttle/controler work

    I ordered a controller for my front hub motor, the closest I could find for matching wiring and it is the proper wattage/voltage 1000/48. The hub motor hookup is pretty straight forward and even the Hall plug matches, so all is well there best I can tell. But the throttle is a different story...

    Front hub shudder/shake video 4 diagnosis

    First cheap kit I got from ebay worked fine and I guess these are no name kits so I'll describe them FWIW as the first has the Chrome circles on the motor, the second was all black and 10$ less than the fist when I went to buy another for a trike I'm doing. The all black kit didn't work at all...
