Montreat,

I have a 2014 Hawk front dinette. I replaced the factory AGM batteries with two Battleborn GC2 100 aH batteries. I had to remove one 1/2” spacer at the front bottom of the compartment. It is a tight fit but a fit nonetheless. The other Battleborn 100 aH battery is, essentially,  a group 27 size.

I have an Intech Flyer Pursue trailer, also. In it, I installed a Lion Energy Safari UT 1300.  Have had it only a few months but it works fine so far. An advantage is that it is a group 24 size. Two of these should drop into the Hawk battery compartment without any problem.

I'd go with battleborn just because they're close. Bout a three hour drive. My AGM's though look like they'll last a while longer yet.

If you need more AH, what about running 3 of the BB 50s in parallel? They are 6.75" length, so you should have room for 3.

 

An advantage to multiple batteries in parallel is that if one fails, you can just unhook it and run on the remaining good one(s).

 

As stated, are you sure you need more than 100AH? You can safely draw the LiFePO4 down at least to 20% SOC, vs 50% for lead acid.

Just pulled the trigger on a Renology 100ah LiPo at $899 less 15% during CYBERWEEK discount.  $837.66 including tax and shipping.

 

We're tired of limping along on our 100ah AGM battery, hovering just above 12v most mornings.  I've done cursory investigation on our Morningstar MPPT controller and the factory IOTA-DLS-30.  They both say they will support lithium batteries, but I'm not sure.  The new Renology battery will fit the existing factory battery box (nominal 7" x 12.75" x 8").

 

My concerns are whether the factory IOTA converter charger will do appropriate bulk, trickle, etc profiles

and whether the Morningstar MPPT-15L will do the same.  We have a fixed 120w solar panel on the roof.

 

I did look at the Renology solar controller (RT) as better option, but their blue tooth app reviews are garbage.  I've heard good things about Victron.  Maybe I should do a hybrid with Victron controller, Renology LiPo 100ah battery, and keep the factory IOTA-30.  I don't know much about BMS, but wonder if this "smart" battery plus a phone app / controller would fit the bill.

Check this out.... a small (big) addition to make the transition for charging smooth... I added it to the Iota as I have a battleborn battery.

Perfect!
I added an IOTA IQ4? dongle when I bought the Hawk back in 2010, but I don't think they were optimized for LiPo batteries.
It was about twenty bucks back then. For $18 I'll get the IOTA IQ-LIFEPO, and that will fix the shore power concern.

Thanks Buckland!

That’s the one I got from the same vendor. It has worked well for me. Keep in mind that the Battleborn BMS is controlling the charging also.
