ToolkitRC M6
Another compact charger by ToolkitRC. It's only 150W but the price is very good. I preordered it on BG but I am considering to cancel the order after all the issues I've read on the big brother M8 (calibration and balancing issues).

I pre-ordered it too... And I'm a bit worried about the issues with M8...
But I'll keep the order and wait to test. If it's too problematic, I'll ask for a refund. |

I juat received the M6, it works great. Its good to see a new approach to processing the charge cycle, most chargers previously used the same controller chip that drifted wildly over time, and had questionable control at end of charge. The M6 (&8) handles end of charge (balance) differently, with cell clamping commencing lower at around 4.1v, progressing up to 4.2v as the lower cells catch up. This prevents the higher voltage cells overcharging in order to bring the lower cells to 4.2v. Older generation chargers would clamp a set load on the cells that reached 4.2v to force the balance, but in order to trigger the clamping, those cells would have to go higher than 4.2v (usually 4.21-4.22v)
In commencing the balance early the M6 does not go above 4.2, in my case, charge voltages only reached 4.196 -4.199 (on a 5 digit logging multi meter) so I'm now just hoping the accuracy holds up. My only gripe with it is the fold out legs. They fall off with the slightest touch, but other than that it's excellent. I have an m8 also, but prefer the 6, as it is quieter and the buttons are easier for quick navigation. |

Testin now, balance charging seems ok, storage charging stops at 3.85v per cells instead of my old Skyrc charger which is set to 3.80v per cell. Should be fine. Tested with my multimeter after storage and cell voltage differences on my 4s 1550mah lipo were within 0.02v (3.85 max and 3.83 min). A bit slow at discharging compared to my Skyrc B6 nano. |

Update: discharge is painful slow, no matter what I set as discharge current (2A) if you set to storage charge a fully charged lipo discharging current is no more than - 0.5 -0.6. 3 hours to storage a 1550 4s lipo to 3.85V per cell starting from 4.2V.
Is there a workaround? |

I'd like to understand if this is a shortcoming of this charger or there are specific settings to speed up things that I am not aware of. I also have a Skyrc B6 Nano and storage at 2.0A, from 4.2V per cell to 3.85V is quite fast in comparison.
