A successful Lithium Battery install #1
Has anyone had good luck with installing a Lithium Battery in one of these old enduros? I'm looking at upgrading to a Lithium battery for my bike. It is a 1971 AT1-c. I have heard the charging system may not hanlde a lithium battery well. Any thoughts?

I installed a Lithium-ion battery on my '72 CT2. Had to modify the battery holder as it's more squat and wider than the original battery, but that's all I did and it has been working like a charm for the last ten months.

The AT 12 volt generator system probably has a "cleaner" voltage output than the 6 volt magneto models...

If you really want the facts, contact some of the motorcycle lithium battery manufacturers and see what they say... I've never tried one and don't personally know anyone who has on an older bike... except that darinm just said he's done it! :likey

Can you tell us the brand and model battery?

Sorry, I was wrong, installed it and have not looked at it since; guess I went with an AMG sealed battery, not a Li-on due to price. The Motobatt MBT6N4 just fits in with some custom adjustment to the battery cage.

I use the sealed batteries on all of my older bikes. Much better & long lasting & no acid leaking :)

I looked into a lithium for my canyon sporty to save a few lbs & it worked well but that is a 12v gen.

My concern is that lithium is a highly reactive metal... I've seen what can happen when a charger malfunctions and overcharges... RC battery... super hot fire and explosion. That's why they sell special fireproof boxes to safely charge RC batteries.

And that's with high-tech chargers... not sure how one would react to the low tech charging systems on these old bikes that tend to boil the water out of lead-acid batteries. If any bike would be compatible it might be the AT with the starter-generator.

I had a defective Ballistic go boom on my R5 project a few years back....

the only sealed battery i found for replacing the 6n4b-2A-3 for my 1975 enduro dt250b was motobatt - mbt6n4. the size looks little bigger than the old one. what mods do you have to make to the battery cage to fit it? i had a good run on my lead acid battery last weekend. did 140 miles and gone up to 75 mph & after the ride. the acid on the battery leaked and had a dead battery now.

You might want to check your rectifier... unless battery case cracked or something.
