Any one done this? I want to add another one for my lights and the radio.

I was looking at getting a battery isolator from Checker auto for like $35. Will this work?

Yes it will work, but depending on where the alternator regulator picks up it's sensed voltage, which is probably internal, the isolator (assuming it is solid state) will cost you about .7 to 1.2 volt depending on load. Another method would be to use 2 relays that get their pull in power from the the alternator, One heard of one disadvantage to relays and that was when one battery is dead, you start for a short time and turn off, during that time the dead battery sucked most of the life out of the good one. Only heard of this once.

With the recent development of the schottky diode, that would be the way to go. It only has a forward voltage drop of about .3 to .5, very acceptable.

PS, If you want to make your own for around $10, PM me.

Thanks for all of the info Kinarfi! Once I get ready too do it, I'll let you know. But I got a lot bigger issue to deal with now.

      Sector E1 Battery change out
      By Gorj
      I am going to replace the batteries in my E1. I am not interested in the high cost Lithium or the expensive 6 volt dry batteries.  I am considering four 12 volt deep charge marine batteries. I have a source for 810 amp units for about $100 each.  I have no worries about reprograming the charger because it went out a few years ago and I replaced it with generic golf cart charger. When I decide to do this, I'll keep you posted on the results.

      Want a new work UTV; who and what should I look for?
      By FTG-05
      I want to ditch my Kubota RTV-XG850 and its moronic twitchy throttle design flaw, get rid of the problematic engine and the 40 mph purposely throttled speed.
      So far, I'm looking at the Honda Pioneer 1000 and the Polaris Ranger 1000, both of which have 1000-1500 lb payload bed capacity.
      What other makes and models should I be looking at?
       
      Thanks for the help!

      Hisun Sector e1 Battery replacement: any tips?
      By didgeridoo
      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!

      Battery Life
      By Gorj
      I am into five years of ownership of my electric side by side and I am noticing some deterioration of power. Although I measured the voltage at over 49 volts, I believe the batteries are beginning to fail. I charge them about twice a week. Last year the charger went out and I replaced it with a 48 volt golf cart charger.  What has been your experience with the batteries?
