Hisun E1 Lithium Replacement Batteries (Australia) & Regen output in amps....

[BuggyBoy]

So these Giant 48v/110ah batteries have just become available: https://www.aussiebatteries.com.au/giant-100ah-48v-lithium-golf-cart-deep-cycle-battery

They look like they could drop in either side of the Controller that sits in the middle of the tray as they are 330mm(W) 355(L) 295mm(H). They can be paralleled, and I think two should be enough. Technically once paralleled the system should output 400ah continuous and 800ah Max (5 secs), more than enough for the E1 - probably 1/3rd more than is needed.

However, the sales person stated that if the regen braking exceeded 400amps, it would put the batteries in standby mode for protection and they would have to be 're-started' with a jumper pack to reset them. Does anybody know the max output of the E1 Regen system, and if it does exceed that, is it possible to disable/bypass the regen so it has a zero output?

Thanks.

I'm speaking speculatively (as in I have not done this). The Sector E1 uses the Sevcon Gen4 controller. You can get PDFs of the Sevcon manual; according to the manual, you can set limits on the regenerative braking maximum current.

That said, 400 amps of current is a lot of regenerative torque/braking!

I know it's probably not the most accurate gauge, but the dial on the dash goes up to 400A (in the red) for discharge, but only 100A (in the green) for regen. I'd very much doubt the controller would put out much more than 100A regen even on a high speed downhill run.

Well, now I'm wanting to easily disable the regen as don't need it and it keeps tripping the battery BMS's when fully charged going down a hill (too much current, nowhere to go) as i suspected it would.

I've attached two pics - on the one called 'Microswitch' is this the switch  that activates the regen based on pedal positions (looks like it breaks a circuit when brake pedal is pressed?).

Presumably, if that switch stayed closed the regen wouldn't activate when braking? (assume the speed-based regen would still kick in at some point though).

The other pic is of a what i thought was the wiring/connector from the microswitch. I unplugged it, the ATV went a few meters then stopped. Plugged it in, and it went again. Any idea what this connecter is?
