 |
|
Requesting user-experiences for the Varley Lithium FE batteries.
For fitment in a Europa with 912 ULS which currently uses a Varley Red Top 25 (cranks at 310A, weighs 7.0kg).
As l understand it the standard Ducati supply voltage of 13.5(+/-) is acceptable as the battery nominal voltage is 12.8v.
If anybody is using one of these l would appreciate feedback.
The Li-16 has a massive cranking current of 670A and weighs 3.2kg. It fits the existing battery box.
The Li-5 cranks at 335A and weights only 1.1kg.
Many thanks for any info.

Well l wasn't exactly inundated with replies to this request. Thanks to Richard for the related PM.
Feedback from Varley (DMS Technologies) is that the Li-16 will provide a better solution as the Red Top 25 CA is 310A and CCA drops to 230A. The Li-5 (along with similar low AHr capacity batteries has a CCA of effectively zero. Meaning that ops in very cold conditions will be worse than l currently experience.
As the Li-16 has an [effective] CA of 670A this should overcome my kickback issues in colder months. It saves around 3.8kg and will need a lengthened battery box as it measures 203 x 78 x 139 (compared RT 25 at 181 x 77 x 167).
Just need to start saving as it's RRP is £678 (yes, there are no decimal points in that number).
The LAA mod process and approved list for Lithium based batteries is here:

Sorry didn’t get to reply as now in Oshkosh and was travelling.
I’ve just fitted a Li-16 for weight saving, not flown yet as I then disappeared of on holiday. Fitted the higher capacity one so if I have regulator fail I have about 2 hours of battery life with all things running.
Dimensions slightly longer than the Varley so had to remake brackets but that was easy.
Starts engine, 912ULS, no problems and I had. Varley 25 previously. Initial engine runs suggest everything ok and charging.

John,
I see EarthX is on the approved list. They sell over here for about 400 USD, which is about 300 gbp.
I did an article in Europa Flyer a few years ago when we installed EarthX. We've since upgraded to the newer version with the fault circuit. We also have added a diode to the C wire to force the voltage to 14 volts that EarthX requires to fully charge the battery.

I couldn’t find a supplier in the UK of the Earth X variants.
Although listed in Aircraft Spruce EU and LAS it’s considèred a hazardous product and therefore either won’t ship or horrendous shipping cost more than doubling the purchase price.

Hi Alan and all
I contacted EarthX a while back and they put me in touch with CFS Aero who have current stock in UK.
