    Dinotte or Similar Li-ion Charger Help Needed

    Hi,

    Does anyone know where I can get a Li-ion charger similar to the one supplied by Dinotte for their 2-cell and 4-cell batteries?

    The specs listed on the Dinotte charger are:

    7.2V Li-ion Smart Charger

    Input: AC100-240V, 0.5A, 47-63Hz

    Output: 8.4V/1.5A

    I'm looking for third-party solutions.

    Thanks.

    What's wrong with Dinotte's? I think it's pretty cheap.

    Nothing wrong with it, but I'm looking for alternatives. Do you know of any?

    Not sure, but I believe they purchase them as completed units. They just changed them recently when they added the higher power lights.

    Will the slightly higher current pose any risk in any way?

    Should be fine, it might make a small difference in the longevity of a 2cell battery, charging it a bit harder, but it won't explode or anything. If the 2cell dinotte battery is at least 2Ah it should be safe to use up to a 2A charger for a 1C charge rate. A 0.5C charge is ideal for longevity though.

    The 4cell battery, no problems up to 3 or 4 amps.

    For another 1.5A option,

    Thanks for the reply.

    I don't have the specs for either the 2 or 4 cell battery and since they're sealed I would rather not disassemble them. :-) Good to know that there's no risk of the battery exploding or something similar. I've been reading too many scare stories about Li-ion batteries misbehaving with serious intent to maim.

    I've also checked out the link you supplied for the batteryspace 1.5A charger.

    Excuse me for my newbie ignorance, but the batteryspace charger is spec'd as:

    Designed for charging 3.6 V ( 3.7V Nominal) Li-Ion and Polymer Li-Ion battery pack with capacity > 1500 mAh
    1.5 A Max. charging current. Power will be cut off automatically when battery fully charged at 4.2V

    while the original charger is:

    7.2V Li-ion Smart Charger
    Output: 8.4V/1.5A

    I'm a little confused about the different figures.

    Thanks.

    www.all-battery.com has a universal 3.7 7.4 11.1 14.4 v li-ion charger that charges at .5 amps

    http://www.all-battery.com/universal...v1-4cells.aspx

    That way if you have other voltages you can use it, and it is easier on your batterys if you care.

    how would I use the all-battery charger on the Dinotte battery? Does the cord that comes with it fit the Dinotte ?
    Any less costly batteries that I could use on Dinotte Lights? I would love a back up spare one?
    thanks to all the experts on this forum for help.

    I'm curious as all get out. Why don't you just use a Dinotte charger with the Dinotte batteries?

    You would either have to source a Dinotte connector or change all connections over to a third party product as well as I believe the Dinotte connectors are proprietary

    Any 7.4v li-ion battery pack should work,pack size just varies the runtime

    The Dinotte and Magicshine both use a standard 5.5 x 2.1mm barrell plug. They just have a bit of molded rubber on one side or the other to cover the joint and lock it together.

    I've used heatshrink tubing to make a magicshine work with my dinnotte stuff.
