love the cocept of this and realize it is mostly for fliers but can we make a version of this with the traxxas style plugs for racers and or like my reason mini's would kinda suck to have to make six power adapter just to use this
Hi Carl, it is rated at 30 amps. Your 6x5200 packs would be a total capacity of 31200 mAh or 31.2 Ah. To charge at 1C that would obviously be 31.2 amps if your charger could supply that but you might be pushing it a bit. You would need a big 750 to 1000 watt charger minimum rated for at least 30 amps at 6s and a big power supply to boot. The board would probably take the 30 amps if HK is a little conservative. You could certainly start around 20 amps and work your way up until it feels warm! Parallel charging will not harm your batteries if you make sure that they are near the same voltage when you plug them in. A few points difference are ok. HK is wrong about must be same capacity. For future ref, charging a 6s 5200 pack and a 6s 2200 pack is perfectly acceptable with the charger set for 7400. This is parallel! Even HK is getting serial and parallel mixed up.
Xtra40, can I ask how you put the jst keyed plug in backwards or should I not ask about your experiences:)
Etienne, thanks for the safety tips but totally lame. All connectors are shielded and keyed for proper insertion except for the banana plugs which should be in the charger before the batteries are connected. 'Touching' them won't harm you as the max voltage is only 25 volts DC. Shorting them is another story. For that reason, I like the other brands that are fuse protected that should limit the damage of the inevitable brain fart.
the conectors are realy male i am looking at it wright now and u can ownly charge baterrys of the same type and capacity so for example you can charce 1-2-3ore4 2cel 6000mha at the same time but you can not charge 2 2cel 6000mha and 1 2cel 4500 mha at the same time
Sorry Xtra40, yes you can charge different capacity batteries a the same time providing they have no bad cells, the same cell count and hopefully very close starting voltage when plugged onto the board. Always plug in the big leads for a few minutes to equalize the pack voltages before plugging in the balance leads. Your 2x6000 and 1x4500 batteries will be treated as a single 16500 mAh battery with a 1C charge rate of 16.5 Amps.
