![]() I took pictures of the Interstates layout of cables before I made the switch I do not rely on memory any more )-: You have to be careful how you route the cables on top of the battery so you can then twist the caps off. I also changed the location of the wood blocks and alum pieces on the door as I have a Victron shunt 500A so one side sticks out a bit more but I am still able to close the door (vertical and horizontal pieces) the same as before. ![]() The screws were on the rusting side so had to be careful not to strip the head. I unscrewed the spacers between the 2 batteries and moved them a bit closer together. I got the GC2 manufactured by East Penn sold under Deka and Motomaster (in Canada) At some point I'll upgrade my 24V to 13.5V voltage converter with something big enough to run my slide-out motor, and then I can remove the house battery and put it in another vehicle. I do still have one lead acid for my starting battery, and a lead acid as my 12V house battery to supply 12V appliances, but both of these are topped off by my much larger 24V lithium system that runs my inverters. One big downside cost with lithium, is it MAY require changing out your solar controller, your AC charger and your DC to DC charger if they don't have lithium voltage settings - UNLESS the battery handles all its charge settings internally. Lithium also needs a low-voltage disconnect, but it's usually built into most drop-in lithium batteries. It's better to have an automatic system to shut them off so you don't damage your batteries while your back is turned or it's in storage, and many perfectly healthy lead acid batteries have gone bad due to a prolonged deep discharge. You have to watch lead acid discharge voltages like a hawk. Lithium batteries are lighter, last longer (some 20+ years or 5000+ discharges), give you more places to mount them (since they don't need vents and can be mounted in any orientation), and sometimes - they can be a lot less expensive. Lead acid may be cheaper at time of purchase, but after a couple replacements every three, four or five years, it might be more expensive in the long run. He is also replacing his 2000w inverter with a 3000w inverter, so that is available as well if your interested in an inverter upgrade to 2000w.Īn issue often overlooked is the limited lifetime of lead acid batteries compared to lithium. ![]() If you can wait and are interested in buying brand new AGM batteries out of a new Leisure for a great price then Start a Conversation with me and I'll help you. Kosinar, I'm going to be helping someone from Beaufort, SC replace their brand new AGM batteries with a Lithionics 315ah battery in their new 2020 Unity RL in April or May when they get it. I am so glad I upgraded to Lithionics Lithium batteries and 3000w inverter because I enjoy my Leisure so much more now that I can run everything in my coach for days, even the air conditioner for hours, and I haven't had to run my generator once for battery charging or air conditioner operation! Lithium batteries and 3000w inverter has opened up a new world of possibilities, that I never realized existed, for how I can use my Leisure. I loved them for almost 2 years until the Lithium bug bit me. I replaced my Flooded batteries with Interstate GC2-HD-AGM Batteries. Plus you can safely and routinely discharge them to 25% SOC, so you get a little more battery/power usage. Also they can take rough treatment and discharge events better than flooded batteries. ![]() I highly recommend switching to AGM lead Acid batteries because they are no maintenance, so no more water level checking and refilling.
