Hello, All! I've decided to replace the traction batteries in my 2018 Sector E1 with a 48V Lithium set. They may be expensive, but I figure the Discovery Dry Cell are, too. I am not looking for the max driving range, as I have never received near the brochured range to begin with, but a good mix of charge/ get work done/ charge is what I am expecting.
I have settled on the 48V EAGL kit from bigbattery dot com. Each battery pack provides 30Ah. The kit ships with a charger, as well. The packs would be physically connected in parallel (using a busbar) to one another, maintaining the 48V voltage, but together would be able to provide the amp draw the buggy pulls when going up hill or towing a rake (rated 320 max continuous Amps). This is in comparison to the serial connection the eight 6V lead batteries. Each of the EAGL batteries looks to have its own BMS; am I correct in thinking I will have to use their included charger rather than (simply) changing the onboard charger to lithium mode? The chemistry of the pack is LiFe PO4, for what it's worth. I haven't torn anything apart yet (to diagram), so I am not sure how the dash will interpret the AMP draw, but the kit I am looking at includes a dash mounted charge indicator.
If anyone has completed a similar conversion, do you have any tips? Specifically, how did you remove the original batteries, and how did you secure the new ones? I am guessing that almost any change from the stock batteries would involve at least some modifications. Any tips would be appreciated, especially things I may have failed to consider. Thanks!

I had a problem 6-8 mo ago when the unit would not start . But you could see power on the dash. The starter solenoid was replaced and it has been fine until yesterday. When I started it up I noticed a high pitched noise coming from under the front. Like a alarmbuzz ..It seemed to drive fine so I went ahead and used it off and on for a hour or so . The noise would not go away . I parked it in the shed and lifted the hood . It seemed to be coming from the battery compartment ( where the new starter solenoid is) I jiggled the connections and the noise changed timbre and then the machine went dead. No power at all . No lights . When you cross the two poles on the starter solenoid ( previously last year it would start and run ) nothing. Checked the battery and it is fully charged . I checked the fuses inside the battery box and they all looked good but I must be missing something. Anyone have a clue what I need to do next to R&R. The closest repair place is 2 hours away in Mississippi . Any help would be appreciated.

I have 2008 Cub Cadet Volunteer Tracker. Was running fine, parked and next morning electric fuel pump inop. Checked voltage had 4.2 volts. Swapped relays in fuse box, checked all fuses (good) and still low voltage. Does the ECU control the voltage to the fuel pump or which relay controls the voltage to the pump?
Have checked all wiring and not found any place it could be shorted (not saying I may have missed something). I am at a loss. Need Help Please.

Okay folks. I have a low power issue. Been like this for a few years. Place I work at bought 3 and all have lost most of the pulling power. They gave them away after local shop worked on one for 3 months and it had great power for about 1 month and then crap. They replaced throttle body, fuel injector, spark plug and IAC motor. Seat belt switches have wires cut and left open so no seat belt warning light anymore. It revs to 6k rpm in neutral but when put in gear and take off in low it just doesn’t seem to want to go anymore. Running 93 octane fuel with Stabil. Any ideas greatly appreciated. I dont have a scan tool but no codes on dash. If held to floor it pops a little and runs almost 5K rpm but if I let off pedal about an inch it smoothed out and revs up to 6k rpm.
