AKK parallel charge boards

I received two charging boards from AKK, one  for 1S batteries and one for 3-4S batteries.

So let's start with 1S board. This one is for all those pilots that fly micro types of aircrafts powerwd by 1S battery. Board itself has 5 independent ports with Micro JST 1.25 and JST-PH 2.0 connectors. And I received additional 5 pieces of JST-PH 2.0 male to Micro Losi female and JST female cable adapters, which cover all types of 1S battery connectors available on the market.

Regarding power supply, you have 2 options. You can use standard USB to micro USB cable or charger from your mobile phone to power this board or any 2-6S LiPo battery with XT60 connector. That is really handy if you want to charge your batteries on the flying field.

If you use USB cable or mobile phone charger, be sure that it can provide at least 2A of charging current.

Another great feature is that for each channel you have switch for changing the charging current from 200mA to 500mA. All channels are set to 200mA by default, and I would suggest that you charge your small capacity batteries (up to 500mAh) with that current. Batteries over 500mAh capacity can be charged with 500mA .current.

There is also one blue LED for each channel, which will be turned on when you connect the battery, and turn fully off when battery has ben charged.

Second board on my review is XT60 parallel charging board for 3-4S batteries.

You will need charger for this one, and this one requires that you charge batteries with the same capacity and cell count as all of the similar boards on the market.

But, as allways with AKK, they have added something that other boards do not have. First are the fuses between all XT60 connectors. Why is that needed? Well, some hobbysts (like myself) often solder their battery connectors by themselves. and if at some occasion someone reversed polarity...that is where fuse comes in, it will prevent short circuits and battery damage or fire. Excellent safety issue.

Second is small LED display, which displays voltage for every cell and total voltage of the battery.
