It’s come to my attention that this article has quite a number of discrepancies and incorrect pieces of information. Given the inherent risk associated with charging LiPo batteries, I have decided the responsible course of action is to remove the article entirely.
Thanks for visiting!

This article is WRONG about charging rates! At the start of the article, the author states that this is a form of parallel charging. It is NOT. The 1S lipos are connected in series, and are charged as a multi-cell lipo. As such, the 1C charge rate is the capacity of your lowest single 1S lipo. For example, if you have 3x 1S/300mAh lipos on this harness, you would set your charger to 3S/300mAh for a 1C charge rate (NOT 3S/900mAh).
TweakRacer is absolutely right, this is not parallel connection but serial connection, so the voltage is a summary of all batteries which will be visible in a charger as a 3S battery (11.1V), and still 300mAh. So the current for a 1C rate for this particular example will be 0.3A
Thank you both for pointing out these errors. I’ve decided that given these errors, other errors, and other technical inconsistencies in my article, this isn’t a safe DIY project to be attempting. As such, I’ve decided to remove the article entirely.
