Product overview
Shenzhen Grepow Battery Co., Ltd.’s Tattu TA500 is a smart balance charger for drone batteries, intended for drone soccer training, competitions, club operations and school teaching. Its compact body weighs 930 ±30 g and contains six independent charging channels, allowing up to six compatible batteries to charge simultaneously. Maximum total output is 500 W, with up to 5 A charging current per channel. Independent channel monitoring provides real-time charging status, while protection mechanisms include automatic stopping when charging is complete.
Electrical integration uses a 100–240 V AC, 50/60 Hz supply with maximum input current of 6.5 A, plus XT30 and G-Tech balance-charging connections. Charging and storage modes are provided, with operation specified at 0–45 °C. Specified compatibility is limited to 2–4S G-Tech smart batteries, although ordinary-battery charging after setup is also described. G-Tech batteries receive automatic parameter matching, with a default charging rate of 1.5C and default fast-charge rate of 3C; the fastest stated charging time in that context is approximately 20 minutes.
