Too much voltage surge. Your PKZ instruction manual says not to have the vehicle running when charging ... because when alternator kicks in with its extra voltage/amperage surge it will blow smaller rated fuse in PKZ charger. DON'T put put a higher rated fuse in your PKZ balance charger.


1C for 1350mAh = 1.35amps; 1C for 2000mAh = 2.00amps; etc .... It's a generally accepted safety guideline. HOWEVER, when charging (balance charging) only via the smaller multi-pin connector, 2.5-3 amps is the upper limit that the small wires of the balancing connector can handle with 2 amps being the preferred safety limit. That's because of the small wire size ... also reason why most upgrade to a balancer that charges through the discharge connector; while balancing through the multi-pin balancing connector.

So, for example if you were charging a 3S 11.1v 3300mAh LiPo pack with your PKZ balance charger you wouldn't be able to charge it at a 1C rate of 3.3amps, but rather 2.0amps or a charge rate of 0.61C. You possibly need to consider using an AC/DC balance charger that charges through the discharge connector, while montoring the balancing through the smaller white multi-pin connector.

Another option is putting in a plug jack and getting an AC wall adaptor. This is what I've done in the photo using an AC wall outlet adaptor rated at output of 12VDC and 1200mA. I am currently doing some experimenting with this PKZ balancing charger, with a 3S 2200 mAh 12C PKZ LiPo and E-flite Cell Checker to see if this PKZ balancing charger is capable of fully balance charging each cell to 4.2 resting volts and if not where it stops and how evenly balanced are the individual cell's resting voltages. The highest charge rate possible using an output of 1200ma(1.2amps) is 1200 divided by 2200 = a charging rate of 0.545. However, my topping off charge rate will be closer to 1.0 amps or a charge rate of 0.45C
