Anyone ever use any of these batteries?

They sound like a great way to loose a couple lbs. high up in the frame. Not much costlier than a regular yuasa battery. Smaller size so you could carry a sandwich when riding

 

links would be nice. are these direct replacements or what mods would be needed (dont tell me i have to make a bracket, im lazy). my bike could always afford to lose a few pounds, as far as me, no way, im too skinny as it is.

 

I assume it's these.

I sent the ebatt guy an email and he said it should work with no problems on our bike.
I am really interested in this mod but I can see some possible problems.

 

Lithium battery technology. While it does offer a whole lot more, there are some draw backs. For one, lithium batteries are more dangerous when they are impacted or crushed. In extreme cases, they have been know to catch fire. Also, they require special charging methods. They can't be discharged below 3.0V per cell safely without damaging the cell. Or over 4.2V per cell when charging to prevent swelling. In other words, if you kept cranking the engine over until the battery dies. More than likely, the battery will be permently damaged. For the good side. They offer explosive instant power. Fast recharging. Can take more cycle of charges than any other battery. Lightweight and the most power per cell vs weight.

 

I was looking at the e-Bats. I still might get one. I would love to loose those couple pounds where the bat is and move the battery to the air box.

 

I think charging is the main concern.
As has been pointed out, Lithium Ion batteries are less robust in regards to charging.
The e-batt guy reckons he has developed some electronics to enable safe and reliable charging straight from the bike.
Prior to that you needed to use the supplied charger to charge the battery before you ride and when it's flat, thats that. No charging from the bike.
Great for racing but it won't suite guys who use there bike to get around town.
TurnTech are suggesting plug and play.
Super-b look like they suggest using their charger which suggests that the bikes on board charger is not suitable.

mmm I'm still very interested.

 

Looks like super b is offering two types. 'Type 1' is charged from the bike while 'type 2' is from a wall charger only. They also appear to have the most rugged cases of the mentioned brands. Reports from cusomers of these types of batts have been good so far, but I'm wondering how long before the built-in regulators crap-out. That would make for a pretty exciting roadside event. Quick release brackets anyone?

 

Sounds like you know what it means.

Charging from the bike's electric system is really an easy problem to over come. Battery will just need to have the charger built-in with it. With Li-batteries, the proper charge method is a CC-CV (Constant Current - Constant Voltage). In other words, a constant current rate is applied first until the battery voltage reaches a certain point. Then it maintains that voltage until the current rate drop to a certain point.

 

I wonder if it would fit inside the air cleaner box with the lid off?.....No seriously would it?

These are all videos of Lithium type batteries gone wrong. The third video is a lithium-ion while the other videos are LI-Po (lithium-polymer) batteries. The problem is the lithium, I believe, once exposed to oxygen it burns like a jet engine.
I understand wanting to save weight but I would rather not have a bomb under my ***. I would need proof that it works with our charging system and I want to see tests about how strong the cases are for these batteries.
