trying to figure out L16RE vs t105 at 48 volt worth the diff

BOTTOM LINE

This should be a question of battery LONGEVITY and not a question of PERFORMANCE.

The L-16 battery has much thicker positive plates. This BCI group size can take even more abuse than a GC 220 golf car battery. A properly care for L-16 will last roughly twice as long as a properly cared for golf car battery.

But the penalty is volume occupied, weight, and cost.

I'd go with however many amp-hours you can fit in there not just getting a particular battery because you can carry it (I don't get that at all). Like PT mentioned, you could get 6 2V batteries and wire them in series for 24V (and get a 24V inverter....would need larger wire than a 48V inverter) but in order to get the amp-hours desired, those batteries will be even heavier and more expensive than the L16's. Ah, you mentioned backup for your house too. Get the L16's, that's the most used off grid home battery. Well proven. Yes, 2V are used but mostly on the I have lots of money setups. What toy hauler do you have?

Sorry for short replays I'm on a iPhone , I will be recharging with shore power and 8k genny 10k surge .

I don think ill ever run the inverter flat out . Just want a lot of reserved power so I only have to run the genny a little bit . This is for a toy hauler camping the frame is 1/4 6 inch 3 tubes running back made for hauling a race car.

Hi,

Try comparing in watts. 6 x 225 = 1350 watt-hours. 6 x 370 = 2220 watt-hours. In each case 50% is useable. Of course to get to 48 volts you need 8 of each. Few rv's have the space for 8, and few have that much storage capacity.

2220 x 8 = 17760 watt hours, getting you near the range of storage for an electric car.

If you really intend to run a 4400 watt inverter "flat out" you may be better off with 12 volt jars, or if you have the bucks six large 2 volt cells.

The other issue is how to recharge a large bank.

one is 225 amp hrs other is 370 amp hrs.

well it looks like i can only pull(t105) 10 amps per hour and(l16) 18 amps a hr for 20 hrs

its sound like it wouldn't last long powering a camping ? but i feel like this is way more then enough batteries with a 4400watt 48volt magnum inverter

T-125's are only 4lb heavier than the T-105's. The T-145's are 72lb, and guess what happens when you bend over and yank them onto the shelf.

BTW- Magnum makes a 48v inverter?

It depends on usage. I would have to go with 67 vs 120 pounds. :)

You can also buy a T-145 with 145 minutes at 75 amps. I would not recommend a L16 in a RV. They are just to heavy! I would rather carry a 67 pound T-105 than a 120 pound L16.

Where is everyone carrying their batteries to? Mine stay in the RV. Also, with a 4.4kW inverter and 48V, he's not buying a pair of batteries, he's buying at least 8. That's 900Ah but I'd rather have 8 L16's at 1480Ah AND MUCH thicker plates.

Hi,

I can tell you that my pair of T-105 batteries are good for 150 amp for 5 minutes to run the toaster. The actual T-105 means each battery can put out 75 amps for 105 minutes.

The T-105 and T-125 are the same size, but the T-125 is about 10 more pounds of lead in it. The T-145 is about 2" taller and about 80 pounds each.

The maximum amp hours are done in a lab while discharging the battery slowly, and with a resistance load, starting at 13.5 volts and going down to only 10.7 volts. So the rating of 10 amps per hour or 18 amps per hour are to get the most amp hours out of the battery in a lab.

To get the best bang for your buck, then a pair of golf cart batteries will give you about 220 amp hours at 12 volts. Two pairs is 440 AH, and only about 280 pounds. They come in easy to lift 67 pound packages. Try lifting a pair of L16's and I will call you sir! They are about 100 - 120 pounds each.

I was considering changing to T-125's, as they fit in the same location, with no change in battery size. Or I can use T-145 without any problems because I have about 6" above all of my batteries, plenty of room to check the water. I changed from T-105 to T-145 in a work golf cart. It provided a LOT more power than the worn out set of batteries.

If it is a home system, then I will go with L-16's and have someone strong install them. I will probably use two strings of L-16's and have about 740 AH of power at 48 volts. This will run my Outback 8,000 watt grid intertied inverter for hours providing power to my emergency loads. Then when the sun comes back up, the 6,000 watt solar system will keep the battery bank full, even if I don't have grid power. With grid power, the inverter can sell back to the grid.

48 volts at 220 amp hours is about 10,000 watts. Plenty to run a RV. But who has a 48 volt alternator? That is why most RV systems are either 12 VDC or 24 VDC. Yes you can buy a 24 VDC alternator for most diesel engines. However you will also need the 12 volt one for running the other stuff. Some engines can run two alternators at the same time.

I have four L16E-AC's (not the RE's) also rated at 370Ah each but wired for 12V (series/parallel). They work great but what do you want to use the 4.4kW inverter for?
