 Posted: Mon May 18, 2015 12:43 pm Post subject: Lithium Battery Update |
 |
|
I purchased a Aerovoltz Lithium Iron Phosphate battery last summer. As I discussed last summer the battery is incredibly light. I received comments that lithium batteries needed to be recharged often so I left the battery in the plane last winter in Michigan. The engine started just fine this week with no recharging.
I have ordered a balance charger and plan to balance the cell voltages from time to time.
Last summer there was a discussion about Lithium batteries being sold in AH equivalent capacities. This is true so if you have concerns about battery powered devices continuing to run after the alternator quits you may want to order a larger battery no matter what type of battery you purchase.
Note! There is a notice on the Areovolts web site warning that Rotax voltage regulator model 866 080 should not be used with these batteries. They report that these regulators have been known to fail and over charge. Apparently there was no fire but a
melt down.
Again worth what you paid for it.

Hi, for what its worth. I rigged a small solar operated battery charger on the roof of my hangar. Totally trouble free apart from having to wipe the muck off the panel occasionally. Battery was always fully operational. Pat

Me too, Patrick.
Odyssey batteries last a very long time since I installed a solar powered charger and conditioner.

I'm trying to get a discussion going on lithium batteries.
Lithium batteries loose app. 10% of their charge per year so storage maintainers aren't as necessary. They do appear to have cell voltage imbalance issues when charging. I would assume as the technology matures on board balance chargers will be more available if not standard. The batteries last longer if cell voltages are balanced from time to time.
I found a lithium balance charger on amazon for $55 and the required 4S (this is a 5 contact connector for the 4 cell 12 volt lithium batteries) balance charging cable ends with pig tails. The cable ends come in a ten pack so if anyone needs a pair of them I will have a few for the cost of shipping.
