Security
If you need button top protected cells and a reliable charger, get this. The XTAR VC4 Plus is the best 4-bay I've owned. The cells are top quality, hold charge well.
The included batteries have protection circuits that work as expected. The charger never overheats them. I use them in headlamps for caving; they last entire trips.
Charger arrived quickly with two 3500mAh cells. The cells were well matched. The VC4 Plus gives a capacity readout that matches my tester. Easy to use.
I use these batteries in my door lock and wireless cameras. The XTAR charger shows all the details. The button top ensures solid contact. Batteries have consistent capacity.
The VC4 Plus pushes 3A across all slots with the right adapter. These protected 3500mAh cells are slightly longer, but the springs accommodate them. Very satisfied.
