  1. Installation shouldn't be too difficult if you've got some pipe and a flaring tool to hand. It's working out where best to put the thing that's going to be fun! They're not very expensive, so I think I might give it a go.
  2. Intrigued by this idea. My parking brake has been disconnected since I changed the batteries six months ago. I've become quite adept at parking in such a way that the buggy doesn't roll anywhere, although there have been a couple of times I've done that and one of the cows has started using it as a scratching post and sent it off down the hill!
  3. If it's still working the brake lights there might be a problem with the connection to the controller/inverter. I couldn't find any other way the braking system talks to the electronics, and joggling the switch a bit made my regen under braking work again. Best of luck with it!
  4. The 'brake' regen is triggered by a tiny microswitch on the brake pedal. It's an on or off thing, and can get stuck easily. Have a close look at the pedal and you should see it. I've had to give mine a careful clean a couple of times now, but that seems to sort it.
  5. I'm in a similar position, having shaved a mere 230kg off by my DIY lithium ion battery replacement! I know very little about suspension setups though, so really not sure what to adjust.
  6. The lead acid Discover batteries in my buggy were getting so bad I could barely do four miles before it ground to a halt. Dealer wanted £1600 for a replacement set, and going down the LiTime or Relion route was going to be just as pricey if not more so, and UK availability isn't good. Instead, I bought a couple of nominal 22v battery modules from a crashed Peugeot E208 for £200 each, wired them up in series and reprogrammed the charger to a basic lithium ion setting. It works fine, and with the two modules would easily do 15-20 miles before the meter on the dash goes down to three bars. Fully charged, the two modules together give about 52v, which is plenty to make the buggy zip along. It worked so well I bought another two modules to put in parallel and double the capacity. As yet, I've not sorted out any battery management system, which I know is a risk. It's on the list of things to do - I'd be happier charging to 80% than 100% every time - but the modules have very basic BMS built into them which gives some protection and I do all my charging outside just in case. So far, the batteries haven't even felt warm either in charging or discharging. I've had to do a bit of work on the underside and rear of the tub to mount the batteries and make it more mud-proof and there's room for improvement there. Overall, I'm very happy at having saved £800 and made the machine much more usable. The modules weigh 12.5kg each too, so I reckon I've shaved about 230kg off the weight of the vehicle. I might have to put a little extra weight back in as it spins the back wheels on steep grassy slopes a bit now. Not helped by the 4wd not working at the moment - another thing to fix.
  7. 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.
  8. What condition is your 12v battery in? By which I mean the little one that sits right under the driver's seat? After four years it might be on the way out, and that could explain the occasional misfire on the solenoid. It's the 12v supply that turns the solenoid on, connecting the 48v battery set to the controller and motor.
  9. Good luck, and let us know what it is if you find out!
  10. Not sure what happened there! Didn't mean to repost my earlier reply. I'm no expert on the charger, but as far as I know, the two digit readout lights up when it is on, either with a status or a rolling error code. If it's not doing either, then there's something else wrong. I read a thread a while back about road crud getting into the power connector, so it might be that or a corroded connection. You need to be very careful and isolate the battery pack before poking around though. UK spec E1s have a big red circuit breaker button to turn everything off, which I don't think US spec ones do.
  11. Is there a code displayed on the charger itself? If you look in over the front wheel from the driver's side, you can see the charger's own display cycling. It should show up an error code there. It's a Delta-Q ICL series charger, if memory serves (and they've not changed it since mine was built).

  13. A fuse is designed to stop the system from drawing too much current, so changing it for a larger one is probably not a good idea! Replace it with an identical one, and hope it doesn't blow again, as that would indicate something else wrong in the charging circuit.
  14. Might be E013 here? https://support.delta-q.com/hc/en-us/articles/360044018472-IC-RC-ICL-Series-Faults-and-Error-Codes
  15. Yup. Every time mine goes up on the lift so I can grease all thousand and one grease nipples, I squirt a little silicon WD40 into the spring bushings and for a few miles it's as quiet as anything. It doesn't last though, particularly given the terrain I drive over. Still eking out about five miles from the old batteries. I really must do something about a li-ion upgrade sometimes soon.
