Insufficient data. I guess "1800W" means a 35A controller? So to support that load, the battery cells, connections, plugs, and BMS all must be capable of 35A or greater continuous current.
What do you know about your battery?
E-HP said:I read the question as the battery is 48V with a 15A discharge rating. Then did the math you did, which seemed to indicate "yes" he's in trouble since he need 35A but only has 15A.
Chalo said:I can't think of any reason to continue using SLA batteries in a vehicular application. Maybe if you can get them for free, and your vehicle somehow benefits from being heavy. Even then, nah.
SnuffysBluff said:Sorry for the unclear information..
4 12v 15 Amp Hour AGM batteries, dc brushless 48v 1800 watt motor, 48/72v 2000 watt 45a controller.

I like these batteries and have many fun runs with my Grandkids on various of my builds.
I top off after even short run and these batteries last forever.

The long recumbent was 48v 20a lifepo4 powered that Ping built in two parts for me.
inoperative now...may switch to agm if I feel like it.
The big rear wheel/small front wheel bike in the back has a geared front hub motor and had a Japanese lithium tube battery that is also long gone. Fun ride while it lasted.
I just don't trust lithium and they are too expensive.
Haven't bought lithium since 2010. Maybe the vendors or batteries are better now...I dunno.

SnuffysBluff said:Bike insist on turning left due to the torque on the right wheel.
And the chain jumps off the motor sprocket.
Going to try a smaller 500 watt motor and controller.
If that doesn't work well, there is another thing to try before I go back to that !!!@#$%&!!! push trailer.
This is great fun, tho.

Of course you're right Chalo; my condescending friend.Chalo said:If you put all the drive power on one side, you will get torque steer. Give it less power, you'll get torque steer with less power. It's still getting pushed on one side only, and it will still turn towards the unpowered side.
If you put a front hub motor on it, the motor will pull in the direction you point the front wheel. That's a good thing. You should try it.
