Good testing, still i wonder why no one put a controller or chip that hold the voltage 20V so it can operate same peformance at every level unless it's overheat and cutoff when reach 25-20% capacity for battery and tools health.

Come on global brands, you guys can make it right? And i still waiting for them to use 21700 type for bigger capacity but cheaper.

Nice video man, always wait for what else you gonna post.

Expected. From my, so far, experience with a brush cutter with 2x5Ah Ingco batteries (40V - 36V nominal), below 2 bars the performance drop starts to become noticeable. Usually I stop before the tool cuts power (undervoltage protection, around 30V I guess) because, as I see it, the last 10% of energy doesn't offer much of work done, no point in draining the batteries and reducing life cycles.
Each battery, fully drained, measures around 16.5V (recovered voltage at rest) and at two bars one would expect around 18-19V while fully charged is around 20.7V (at rest as always).
Since the motor is limited, by design and controller, to a specific max current this leads to less power (power = voltage x amperes) while the battery drains (voltage drops).

PS: The voltage values I mention were measured with an Ingco DMM and are from memory so they are approximations.

What happened to the 8ah and 4ah ingco battery with 21700 cells they advertised. They never released it

These batteries claim to have overdischarge protection but im not sure they do. I over discharged one with a leafblower and it killed one of the cells inside, wouldn't recharge after. Had to take it apart and recharge each cell individually as there is no cell balancing either and replace the faulty one. It works fine now but becareful not to let it drain too far. I always recharge the moment they get to one bar now.
