whats up with the new molicel p30b?

[MankeMane]

i recently checked their website and it claims that the 18650 battery has a 36 amp cdr (wich i really call bs on) and can be charged at 9 amps
heres what they say on the molicel[.]com website:
"INR-18650-P30B is the market-leading ultra-high power cells with best power-to-energy ratio ever in 18650 format. It features 3.0Ah for 100W discharge and 3C fast charge power."
if this is all true then where in the world could i find a charger for them that can do 2x (or maybe even 4x) 9 amps?

Well I don't know any charger that will do 9A. Unless you go with a RC charger or a variable CC/CV power supply (which you have to end the charging manually since there isn't any auto shut off). But even if you do charge them at 9A, I won't do it. Since the number of recharges will likely be lower for the life of a cell. We know 500mA to 1A is perfectly safe. I charge some at 2A and 3A and I don't have the data yet to know if this shortens their lifespan or not.

Besides RC chargers and variable power supplies, I too just buy 4 bay chargers. Although I just stick with xtar chargers. They have dozens of models and are having their 18 year anniversary now at 20% off for another week. I have used the following: VC4 ($15.92), VC4S ($24.00), VC4SL ($27.12), and VX4 ($54.72). I wouldn't bother with the VC4S. It uses a microUSB plug with QC3 charging. While VC4SL and VX4 uses common USB-C cables. Only the VC4 works from a standard USB 2.1A source (or as low as 500mA). And the VX4 also charges LiFePO4 and lithium 1.5V cells. Something you probably aren't interested in. And they ship only from China with a $15 shipping charge.

The advantage from buying from xtar is free US shipping (if shipped from the US) and they honor the warranty. Other places they probably won't. I believe the warranty is 2 years.

You can buy any charger you want, whether made by XTAR or not. Most chargers including the ones I mentioned even though they will charge a cell at 3A (the VC4 is only 1A), means for just one cell charging. More cells means some or all will get less than this. Some chargers will charge at their max rating for all four cells.
