You must consult with a properly licensed engineer before duplicating any of the modifications described within this atricle. This article descibes a change to my aeroplane that I found to resolve a problem with guidance and checking from an LAA engineer.
Originally the plane had an Odyssey battery. When it got too old and stopped working I replaced it.
My LAA engineer recommended the Fulbat NH12-20. It uses GEL technology so it won't leak fluid if the airplane leans over. It's a lot cheaper than the odyssey battery.
It had different dimensions so I made a wood battery box that used the captive nut positions of the old box. The new box has a front section that comes off with screw in wood captive nuts. This makes it easier to remove the battery. The battery is held in with a large velcro strap at the top. The box is sited on the cabin side of the firewall.
The new battery has been in use for a couple of years. I find it starts well even during the UK winter. It has a capacity of 21.1 Ahrs and a CCA of 235 Amps. It is the same battery used on popular BMW motorbikes. It weighs 5.55 kgs.
