Kolbers,
In a few months I will be needing to buy a battery for my Kolbra….so, I am wondering where we stand in the debate between Lead acid and Lithium.
Thank you as always for your insights!

I use, and have used for many years, an AGM lead acid battery. Works well for me. Is very reliable and serviceable for many years. Keep mine charged with a small solar charger that has a conditioner/maintainer capability.

Guess I am a tad old fashioned. I'll let others test fly the lithium batteries until they are refined enough I know they won't burst into flames while I am 90 miles from nowhere.

That is a good question. Wish I knew the answer.  Lithium has overcharging or uneven charging issues, Good side, it is very light....while lead acid is heavier, no charging issues.  I use the recombinant gas technology. It is more like lead acid but can't spill. I have taken apart a ups(uninterruptible power supply)  found a crack from the top right corner across every cell to the lower left corner, zero leakage or damage to the ups.   My last one lasted 9 years, it was still starting the plane, but I could tell it was turning a bit slower.   Mine is a 17 amp hour out of a harbor frt jump start.  Buying the jump start was cheaper than buying the battery from Arizona battery.  The one that lasted 9 years was a replacement battery for my jump start... But I don't think you can get it as a replacement part ant longer. It was only 15 dollars but took 3 months to get here. Â
Good luck
My answer is worth what you paid,, and I am sure someone else will have another opinion. Â

I'm still a little leery, too, from a safety standpoint.
Even without the safety concerns, it's really hard to go from a ~$40
battery to a ~$200 battery to save maybe 10 lbs, unless weight is
*really* critical.

Nick, It bothers me that the Li sellers like to talk about Pb equivalence rather than capacity. I've belonged to the AeroElectric Connection here on the Matronics Forums and so far no one has been able to say that they've tested an Li battery for capacity and had it equal an AGM lead acid battery. On average when the Li battery is subjected to a constant discharge, like when you lose an alternator, it has about 1/4 the capacity to keep things running.I don't recall what engine you're going to run on the Kolbra but if it's electrically dependant, ie doesn't have mags or dedicated ignition coils this lack of capacity is critical to safety of flight.
And as for the weight, if it's that critical there are other ways to lose 10 lb. :-}
Rick Girard
PS when it comes to lead acid AGM, SLA, RG (in order Advanced Glass Mat, Starved Lead Acid, Recombinant Gas) are all names for the same kind of battery construction. Right now they are the pinnacle of lead acid batteries but as John notes you don't need to spend $100+ on a brand like Oddysey. I use the cheapest I can find, usually the type used for Uninterruptable power supplies. The $37 battery I put in my trike 8 years ago is still running strong. If you want to be safe, figure on a 2 year life, change it out and use the old battery for a motorcycle, snowmobile, emergency radio power supply, etc. That's only $20 a year to ensure you always have a top notch battery in your airplane.

This is the one that I use and have a cheap float charger that I Â keep on it when I am not using. It has been in service for three years so far. The problem is if they are regularly discharged, the float takes care of that.

Spend 99.00. Replace the battery in 8 years. 12.00 and change a year. The url I posted is also offers free shipping. That is a 16 amp bat. Works well on a 912uls.
On the other hand, I have the same capacity AGM battery powering the 5.5 kw Onan Generator in the back of my truck. Think it may be a Power Sonic, or some no-name brand Absorbed Glass Mat battery. It was cheaper, bought it locally, lives unprotected from the elements, 24/7. Cannot remember how many years I have been using that one.

I use an Odyssey PC625 for my 912S. Have had it for about 5 years. Last year after setting for 5 months during winter it would not turn the engine fast enough to start. Charged it up and now keep it on a battery maintainer. So far so good. It weighs 13.2 lbs. and I moved it to the front to help my weight and balance.

Recently replaced mine with a AutoCraft Lithium, LFP-7, it’s the same one, that Bryan Melborn is putting in his builds, except it is the larger size. So far so good.

I replaced my lead acid battery with a Areovoltz 8 cell lithium FE battery
about 18 months ago. I had been using a cheep 12 AH lawn mower battery that
weighed app 13 lbs. The lead acid battery was marginal at best. On a cold
morning or after few starts without any charging it would fail to power my
ignition system. Maybe I should have used a bigger battery but I don't like
weight.
The new Areovolts battery is a 15 AH equivalent and weighs 1.8 lbs. Last
spring when I got back from 6 months in Florida I tried to run the battery
down with six 5-8 second cranks with the ignition off and with a cool down
between each crank. I gave up not wanting to wear out my starter. I then
started the engine perfectly. I then hooked up a balance charger and found
the cells were within .02 volts of each other. The balance charger couldn't
improve on the already good balance.
I hear discussions about the AH equivalent rating but from what I have
experienced my old lead acid battery would drop below the necessary voltage
for my electronic ignition well before the lithium battery would quit. I
also have a alternator that bolts to the flywheel and accessory case so
there are no moving parts other than the engine. If you have to have more
reserve power get a larger lithium and you will still save considerable
weight.
The lithium FE batteries don't catch on fire like the older lithium
batteries did. My lithium FE battery doesn't need to be kept on a battery
maintainer like the old lead acid batteries did. After sitting idle in the
hanger all winter there is no measurable loss of power.
I will continue to report on my ongoing test.

Not sure how safe it is but losing 10 LB sounded great. My 6 year old lead acid was dying.

This is the one that I use and have a cheap float charger that I keep on it when I am not using. It has been in service for three years so far. The problem is if they are regularly discharged, the float takes care of that.

Kolbers,
In a few months I will be needing to buy a battery for my Kolbra….so, I am wondering where we stand in the debate between Lead acid and Lithium.Thank you as always for your insights!

Note that it says 'lithium *ion*'. If you ever offer me a ride, please remember to tell me about your battery.
Seriously, the ones that have a (limited) good record in a/c lithium iron phosphate, like Rick described. If yours is really lithium ion (as used in RC model planes, etc), tread carefully.
For reference, EarthX makes lithium FE batteries intended to be direct replacements for Odyssey PC680 batteries. They actually publish discharge curves for their batteries showing similar total energy to the 680, a true 12 AH battery. The EarthX weighs 4.1 lbs; the YT12B weighs 1.1 lbs.
For me, these data points indicate a couple (three, actually) of things. First, the YT12B probably *is* a lithium ion battery. Second, it's probably rated as a 12 AH equivalent, *only for starting*, meaning that if you need endurance from the battery in the case of an alternator failure, you may not have it. Last, there's significantly greater fire risk from the YT12B.
But those are just my opinions; worth what you paid...
Charlie
PS: I'm not advocating for EarthX; it's taken them a long time to publish useful info & their technical spokesperson has often seemed to lack technical knowledge in previous exchanges.

I replaced my lead acid battery with a Areovoltz 8 cell lithium FE battery about 18 months ago. I had been using a cheep 12 AH lawn mower battery that weighed app 13 lbs. The lead acid battery was marginal at best. On a cold morning or after few starts without any charging it would fail to power my ignition system. Maybe I should have used a bigger battery but I don't like weight.Â
The new Areovolts battery is a 15 AH equivalent and weighs 1.8 lbs. Last spring when I got back from 6 months in Florida I tried to run the battery down with six 5-8 second cranks with the ignition off and with a cool down between each crank. I gave up not wanting to wear out my starter. I then started the engine perfectly. I then hooked up a balance charger and found the cells were within .02 volts of each other. The balance charger couldn't improve on the already good balance. Â
I hear discussions about the AH equivalent rating but from what I have experienced my old lead acid battery would drop below the necessary voltage for my electronic ignition well before the lithium battery would quit. I also have a alternator that bolts to the flywheel and accessory case so there are no moving parts other than the engine. If you have to have more reserve power get a larger lithium and you will still save considerable weight.
The lithium FE batteries don't catch on fire like the older lithium batteries did. My lithium FE battery doesn't  need to be kept on a battery maintainer like the old lead acid batteries did. After sitting idle in the hanger all winter there is no measurable loss of power.Â
I will continue to report on my ongoing test.

I have been using a Areovoltz battery in my MKIIIC it is a Lithium Iron
Phosphate battery. Lithium Ion batteries have a history of not tolerating
low or high voltages very well and doing bad things. If we believe the
literature on Lithium Iron Phosphate batteries these low or high voltages
are much better tolerated, at the very least they aren't supposed to catch
on fire.
What I do know is my battery looks to be very well made, extreemly light,
very powerful, and doesn't loose any measurable power with 6 months in
storage.
As always worth what you paid for it.
