    Sometimes, a product comes along and I think to myself, "That's just too good to be true". This was my first thought when I started looking at the new Lektron 35 Watt battery charger. A simple, 2-3S LiPo/LiFe charger, capable of 1-8 cell NiMh/NiCd charging as well? That part was pretty easy to understand, but when the manufacturer stated that the charger automatically detects the number of cells AND their capacity?


    The Lektron 35 Watt charger, made by LHS Electronics and distributed by Hobby People, claims to do just that! Simply plug in the battery, select the type of battery you're charging, and the charger will do the rest. Again, it seemed too good to be true, so I had to put it to the test!


    • Automatic Detection of Battery Cell Count and Capacity
    • Automatically Sets Charge Output
    • Integrated Cell Voltage Balancer for LiPo and LiFe Batteries
    • Highly Accurate Lithium Balance Charging +/- .01V
    • High-Power, High-Performance Charge Circuit

    • None as Tested

    Manual


    The manual is very informative - it walks the user through every step, leaving nothing to question. There's individual sections for introduction to the charger, connecting your battery, and even a section to handle the various fault (error) conditions that may arise during battery charging.

    The Lektron charger is, indeed a compact unit - dimensionally, it is 1.5" x 5" x 2.675" (38mm x 127mm x 68mm). The A/C power cord is removable, and the output cord has a T-style (Deans® Ultra Plug®) connector attached. One additional accessory included is a t-style to Tamiya connector adapter. The face of the charger is laid out very simply, consisting of four multi-color LED lights and a single red button.



    The four LED lights represent the four battery types that can be charged, and the red button is responsible for selection of battery type and starting and stopping the charger. The 2S and 3S balancing ports are built into the charger, and are quite easy to use.

    To charge a battery, in this case a 3S 2200mAh LiPo, the T-style battery connecter is plugged into the charger's output lead, and the balancing plug is connected to the 3S port on the charger. The red button is then pushed once to select the LiPo, then pressed and held a second time to start the charging process. At this point, the LiPo LED will glow a solid red, to indicate the battery is being charged.



    When the battery is fully charged, the LED changes from red to green, indicating the charge is complete!

    The Lektron charger has a maximum charge time of two hours - if your battery has a high capacity, it may not finish charging in the two hour time limit. If if it is not complete, simply start the charger again, and it will complete the charge.



    I tested the charger, and it does everything it says it can do! I really like this charger because it's simple to use - the user doesn't need to select a charging rate or number of cells! This is a great little charger, especially for those who may be looking for their first charger beyond the typical 'wall wart' included with many of the RTR vehicles and aircraft. Its compact size is another great feature, as you'll want to take it to the track or field as well!
