    Batteria eccezionale, per ottenere più potenza da alcuni utensili come ad esempio il trapano DCD999, comodissima la doppia funzione 18v/54v completamente automatica. Spedizione un pò lenta, almeno 7 giorni lavorativi ma ne vale sicuramente la pena. Venditore PowerTools IT serio e professionale, risponde immediatamente ad ogni vostro dubbio.

    1.0 out of 5 stars Don't get hooked on it
    Reviewed in India on 7 November 2020

    These battery are like heroin; you know that it is not good for you. But once you get hooked on it, you can't stop buying it.

    When introduced in 2016, FlexVolt was considered to be the pinnacle of battery technology. 56/60V cordless power tools are considered to be far more efficient when compared to 18v tools. Even today, the other manufactures could match the power, performance and runtime of FlexVolt tools.

    These batteries have 15 cells each producing 3.6v and 2ah. The cells are arranged in 3 banks as shown in the picture. Each bank contains 5 cells producing 18v. When connected on 18v tools, these banks form a parallel connection providing 18v and 6ah to the tool. But when it is plugged to a 56v tool, these banks gets connected serially producing 56v and 2ah.

    There are a few practical issues with this configuration .
    1) Even if one cell goes bad in the battery pack, it won't be able to deliver enough voltage to the 56v tools and it becomes completely useless. See the picture. One of the cells in the first bank is showing 0 volt and the battery is completely useless now.
    2) Another issue is its complicated switchover mechanism to switch between 18v and 56v. It has a slider mechanism and two extra terminals for connecting it to 56v tools. If dirt, dust or debris gets into it, the tool won't work. The batteries used on the tools like angle grinders, reciprocating saws, chain saws and air blowers this is a big problem.

    The quality of the cells used on these batteries are not so good. It looks like at are built for performance not durability. Usually, lithium-ion batteries last last 5 years. But the FlexVolt batteries won't even last 3 years. Both the batteries that came with my 2018 made Dewalt DCS388 reciprocating saw are dead now.

    You need to keep the battery terminals always cleaned. Otherwise the chargers many refuse to charge them. I don't see such issues with Makita batteries or the Dewalts regular 18v batteries.

    I have three FlexVolt tools now. I bought them without knowing the problems and limitations of these batteries. I have no option other than keep buying these faulty batteries at exorbitant prices.
