The batteries will fit in just find but be a bit low from what I'm told. You will also need some ratchet strap or something else to hold them down. The main battery cable is very flexible and you should be able to route it easy enough.

That's an awesome find. I didn't realize you could buy those independent of the vehicles. They are based on the 18650 lipo battery pack. . The great thing about the tesla battery packs is the packaging and cooling. Now that I know they are available I'll look to see if I can integrate them into...

I had a ballistic performance Lithium motorcycle battery. I never ended up installing it because some other owners had put them in bikes and had a hard time getting the bike started in 32 degree F or lower temp. I believe you can store them safely at lower temps but you won't be able to use them...

I am going to stick with the simple Lead Acid 6T batteries in my vehicle. I plan on converting the bed to an RV where I will put a LiFePo4 as a house battery. I will use the "starting batteries" to start the vehicle and run loads in the cab like GPS and Radios. I will most likely add a 1-2kw...

No one got the pricing on the LiFePo4 batteries. I did send a RFQ but never got a response. The mass does not make any sense. The 6T AGM is like 86 lbs. LiFePo4 is like 10x energy density on Lead Acid. http://www.batteryspace.com/batteryknowledge.aspx by mass it should be 1/5. That puts it at...

BTW if you do end up buying batteries from NAPA when you order the acid it comes in the large 6L quantities. You need one box per battery. The local guys had never dealt with a dry cell before. The acid goes into the battery and you charge it completely. Then if the levels are not high enough...

I just ordered them tonight. The guys at my local NAPA had no idea what Dry means. I also ordered some battery acid. Does it come pre-mixed with water or do I also need to buy some De-ionized water?

If you are not done with the wiring project I strongly recommend you use solder pellets instead of crimping. https://www.youtube.com/watch?v=SXDkNMDDrBs I installed some -48V DC wiring in a datacenter and the crimp tool that can do 0, 00, 000 size wires (common on batteries) is $600.

I may go this route depending on how hard it is to source the wiring bits.

How did you handle battery hold down?

Did you end up swaging/clamping or soldering the new battery connectors in place?

Wow excellent modification. So I'm guessing they all fit in as expected? Can you post an updated photo with all the new wiring in place? Doing a quick search it looks like the group 31 batteries have 105 Ah capacity. So that means your total capacity is some 800 + Ah now? Did you opt for...

Wait does dry cell mean I need to fill them myself and change them the first time?

I just went to Napa in San Jose. I can confirm they have them in stock. Time to figure out how many I need. Also the photo they have in the computer shows the flooded model for the D so I hope I will be getting an AGM instead.

Has anyone heard of http://www.navitassys.com/products-systems/military-batteries-systems/ Navitassys batteries?

What model of Optima? Does yours have an adapter plate that makes them fit?

the latest hawker is the 6TAGM. Sent from my SAMSUNG-SM-G930A using Tapatalk

Was there a core fee? Did you turn in your old batteries? Sent from my SAMSUNG-SM-G930A using Tapatalk

That is way below prices I see online! Sent from my SAMSUNG-SM-G930A using Tapatalk

New 6T batteries I'm having the situation where I may replace all my batteries at the same time with new ones. I see that many companies make batteries in that form factor. If you were going to replace your pack what brand would you pick? Sent from my SAMSUNG-SM-G930A using Tapatalk
