Two Slot Rechargeable 18650 Li-ion Battery Charger + Rechargeable 3.7V 3800mAh 18650 Battery for Fla
“Early report. I've run them through 24 hours of discharge/charge test cycles (BT-C3400 Universal Battery Charger Analyzer Tester) and as an electrical engineer, I like these batteries ... they are the real deal ... about 2150 mah capacity ... much better than ultrafire (1100 mah) and comparable to the (also good) DULEX brand.. Some have noted the batteries lack internal charge/discharge protection electronics. Cannot verify this as my system has built-in charge management.
If you have need for low cost, high performance li-ion cells, this seems to be a good deal.”
