Muchmore AAA Battery High Current Charging Tray

Nice charging trays for AAA batteries allows for quicker charging than basic rechargeable batterie trays

Well made, but light weight. Included connector fits well with my existing T-type/Dean's charger leads.

One thing to note: The 4 slots are wired together in series, so you can ONLY charge 4 AAA batteries at a time as it ships, no less. This is fine as they will primarily be for Mini-Z batteries, but I was under the impression that the tray slots were in parallel, which would allow you to charge 1-4 cells (even though then the cells would only charge to the level of the earliest peaking cell). But again, these trays are wired such that the charger will see it as a 4-cell NiMh pack.

Like previous Muchmore (and other brand) battery tray type devices, the tension screws are WAY longer than they need to be for the intended AAA cells, so don't go crazy tightening them down, or you could damage the trays or batteries. With a charger that shows the attached battery voltage (like the iCharger 406 or similar), it's easy enough to see when each battery screw has just enough tension for a solid connection to avoid over doing it. For use with chargers that don't have a display (first off, why bother with this type tray if you're not after the additional info on your packs?), you'll likely get a charger error if you don't have a good connection on one of the cells, so just a light and quick check on the screw tension will probably get you going.

Lastly, remember you're only charging low (relatively) capacity cells, so even though the trays can handle it, don't go crazy high charge rates on your AAA's if you want them to last. I picked up these trays to have more control over the charging and discharging treatment, and to be able to gather additional information about the battery performance for tracking purposes, rather than being stuck with .25A or similar no-display chargers, so I was happy to be able to have a solution to easily use my iChargers.
