Default EarthX ETX900

Does anyone know if the EarthX ETX900 will fit in the 14's stock battery box without modification?

The only info I found was a reviewer and they didn't specify a model:

The above chart lists the battery case as measuring 6.5 x 3.1 x 6.6 - which is smaller than the published Odyssey PC680 dimensions. However the EarthX Battery did not fit the Vans Firewall Forward battery case designed for the Odyssey PC680. It was too thick.

I don't know about ETX900 but their ETX650 should fit the 14 box but will not fit other RVs if they have the 4 sided box. The Odyssey PC680 is actually a bit narrower so the EarthX would be a very very tight fit.

The 14 standard box has one side open so it should fit OK.

Default Same size

The ETX680, 900 and 1200 are all the same size.

Dewey is correct. I replaced two Odyssey 680s with a ETX680 and a ETX900 in my RV-10.

Other than the price, I'm extremely happy with the purchase. I just wish it was less expensive.

Default Consider the EXT900-VNT

I just want to put in a word for the EarthX EXT900–VNT. A little more expensive and a bit heavier than the unvented version, but unique among the lifepo batteries available now in that it features a containment vessel and a pair of vents intended to overboard noxious gasses that would be generated in a thermal runaway scenario. It is really the only lithium battery out there designed to be safely mounted inside the passenger cabin, a far more battery-friendly environment than any firewall-forward location.

Here is the company page:

https://earthxbatteries.com/shop/etx900-vnt

I have a pair of these around which I’m designing a fully redundant twin battery system with enough ampacity to allow not only dual lightspeeds, but a fully redundant twin-electric fuel pump system that will allow me to completely eliminate the engine driven fuel pump from my Airflow Performance FI. I’ll be rotating in a new battery every other year, and slowly populating my cars, trucks, and farm equipment with the ones that are removed from my RV.

The cool thing is that the pair of EarthX’s together weigh 5# less that the one PC680 now mounted on my firewall, and will bump my total CCA from under 200 all the way to 800 Amps! The master will be on-off-on so, except when starting, only one can be engaged to the main bus at a time, with the other being charged via a Shotky diode. I’ll fully document all of this next Winter on VAF.- Otis
