    Just sayin.....
    Do they still require a special charger to charge them properly?

    I use the 240 model.
    Btl1a240c i think.

    All of my rider bikes have BT lithiums.
    I have no issues with batteries.

    Every rider bike (12v) has a BT Lithium in it here.

    I have no battery problems.
    Thank you for the info. My question is which battery charger do you use for your batteries?

    I use two ceiling mounted BT 4 position chargers for bikes at home. There is also a NOCO 4 position charger (it does 6 and 12v) for loose batteries, mostly 6v.

    All of the other chargers are BT lithium wall warts at the remote locations that remain connected to the bikes and plugged into the wall. Except that there is no constant electricity. Every month or so, I run the extension cord to the community outlet for an overnight top off.

    Usually, the chargers are blinking float charge after 45 minutes unless it is the K100. That takes about 2 hrs.

    The BT batteries only need to be charged when they are in a bike that has a voltage draw. Harley Ultra, K100 most notably.

    Sizing the BT batteries is more of a "what fits" than by electrical load. Have had ZERO problems.

    Wish they made a 6v for the horde of small bikes around here.

    I have been looking at these batteries. When I get through playing with the cells I bought and if they don't work out I may buy 2 of these to try. Almost all of these lithium motorcycle batteries have lifepo4 cells in them with BMS circuits to protect from over charging and discharging them too far. They most likely have a charge controller in them to keep the charge voltage below 14.4 V. They don't mind sitting partially discharged it doesn't hurt them no sulfating. But float charging them when they are full is not good for them it reduces capacity. Ideally a lithium charger should turn off and then back on after a voltage set point these batteries may have that circuit in them.

    You can get 2 for @ $100.

    ^^^^Thank you^^^^^

    I have a very good conventional battery charger but would need to get a new one for the LifePo batteries. Oh well, I like tools!

    The link you provided looks like they are manufactured in the same plant as the WPS branded batteries I posted. I did not see a two year warranty on the ones you posted though? I may have missed it.

    29 bucks for the BT lithium chargers.

    Sometimes they can be found for less when ordered with a battery.

    They're much lighter than traditional batteries and I like that...

    Also, I was told by BT that any BT lithium can be charged with any BT charger.

    Again, I have had no issues.
