New Admiral Li-ion batteries charger requirements

[rzing]

The new Admiral Li-ion batteries from MRC look very interesting. I'm wondering if the charger I have will work with them. It is a quad charger from Vista Power Q3620AC 320W 80W x 4, but the programing is very similar to the Hi-Tec ( and several other ) quad chargers. It has several different battery type settings including one called LiIo. Is this a shortened version of Li-ion? Once in that battery type I can select cell number, total mAh of the battery, and mAh charge rate from .1 amp up to 7 amp. What do you guys think, or should I be looking for another setting?

Yes. Lilo is the correct battery selection. I use my Turnigy Reaktor Quad and Single 300W chargers to charge my Li-ion tank batteries. I charge at 1amp just to be on the safe side and with the balance lead connected it knows how many cells.. So far I haven't any of them blown up ...


This is my setting for the Admiral 3500mAh Li-ion pack before charging:


This is during charge:





I should be getting the new Admiral 7000mAh Li-ion pack in the next day or two so I can see how they look. I just read that max charging current for Li-ion is 0.8C which would be 5.6amps for the 7000 but that spooks me and I don't want to blow my new batteries. I'll probably stick with 1 or 2 amps unless someone tells me different. I have the time so I can be gentle with my batteries..

Your charger shall work very well. There are only a couple manufactures and they rebrand for many labels on the market and the programming is virtually identical across the lines.

I guess if I wasn't such a guy I'd have read the back of the battery! LOL!




The new 7000mAh batteries have the text right on the front! Doh...!

My G.T. Power charger is few years old. It has a LiPo setting which I have been using for my plane batteries. It does not have a specific Li-Ion menu choice. Can I use the LiPo setting as long as I make sure not to send too many amps to the battery to charge it?

I recently got a 7000 mah admiral battery can I use the heng long usb charger for it? Or does someone recommend I get a different charger?

I gave some background information on why Lithium Ion pack using multi cell configuration is the best choice for RC tank. You may find it helpful. The new Admiral Li-ion batteries from MRC employs the right idea.

If you have an older charger designed for NiCD or NiMH pack, it will not work for a Lithium pack. The Lithium battery (all kinds) are constant voltage charge device. For safety and pack durability, you need a balance charger of 2A capability or higher. I use a SkyRC iMAX B6 mini charger and am very happy with it. I highly recommend NOT to buy "non-brand name" iMAX B6 charger which may be much cheaper, but the software is often messed up and not upgradeable. (How do I know? I tried.)

Most commercial lithium charger default to stop charging at 8.2V (4.1V per cell) for safety and pack durability. It is a good decision for Lithium Ion cells. But it also mean that your 7000 mAh pack is only 6000 mAh capacity or so. It is a bad idea to push the LiIo pack to 8.4V and its rated capacity. The SkyRC charger software is fully tailorable by the user which I like very much.

I chose 18650 LiIo cells to make my packs. A 4-cell pack fits the Heng Long battery compartment well with room on the side to spare. The charge current limit is a function of the cell used and about 2A for the 18650. I also use 2x 26650 cells to make 5000 mAh pack which can charge faster and has plenty of run time too.

This not a super fast charger which allows you to recharge one pack while using the other. It does allow you to charge the bigger 7000 mAh pack in 3-4 hours.
