I've used these in Aerobatic Aircraft with both harsh and confined
Environments with excellent success. IMHO it would be the battery of choice type wise. I don't know anything about that brand.
A
VRLA battery (
valve-regulated lead–acid battery) more commonly known as a
sealed battery is a
lead–acid rechargeable battery. Because of their construction, VRLA batteries do not require regular addition of water to the cells, and vent less gas than flooded lead-acid batteries.
[1] The reduced venting is an advantage since they can be used in confined or poorly ventilated spaces.
