    it's also possible all these ips are *legit* ips that have been hacked through malware. This would be why they aren't showing up on reports, yet. But is interesting that all the first 2 sets are the same Definitely from Russia, St Petersburg area to be more specific...

    Too bad we can't ban ip 176.59.x.x Problem is, that's a HUGE range of actually valid addresses.

    Maybe there's something like this in the config of the forum. What say you @LithiumSolar

    Remember, Introductions are for introductions. Hiding content inside of an introduction thread keeps others from finding pertinent information they may be looking for as well.

    Yeah, between Pete, Daniel and myself, we've been cleaning house on this little diva. There must of been easily over several hundred ip addresses that connected from. so no way to just block ips for that.

    What is to hot for my cells

    45C/113F is around the temps most datasheets will state for "charging" temps. Discharge can usually be up to about 60C/140F. If the battery is stating in the 90's, you'll probably be ok. But I do agree with if you can get the ambient lower, that'd be better for the cells. I looked at the...

    Question about Lithium cells

    It is, limit 1A per module. If you had 3 connected in parallel, then that'd be 3A. You could also go with a TP5100, which can do 2A, I think I don't recall what cells you have. 2.33A seems a bit high, to be honest. If these are cells pulled from a laptop or similar device, then that is way too...

    What is to hot for my cells

    Considering that the batteries are in the shade and not on the road top, you should be fine. ie, those batteries are designed to be sitting out in a parking lot that is covered in black tar that can reach temps of over 150F easy, and they still function just fine. Sure they are under a car out...

    Question about Lithium cells

    If a cell is designed to charged at 1C, which is mAh / 1000), then 3 cells in parallel would be x3, or 3C In other words, if a single cell only gets charged at 500mA, then 3 cells in parallel can be chaged 1500mA and still be fine, because each cell is still only getting 500mA. I used the "x3"...

    WTB: New 8 or 12 Sony VTC6 cells(US)

    Letting us know your general location could help get a bit more bites as most are more willing to meet instead of shipping.

    Question about Lithium cells

    The amount of higher current won't be enough to damage the motor. It'll just get hotter, that's all. And not enough to burn it up. What really damages the motors is when the voltage is way too high, which causes them to spin much faster than designed. You can normally go 25% above rated (ie, a...

    Question about Lithium cells

    Using a buck convertor on the 3s would work just fine. The 3s would operate at a lower amp load on the cells than the 2s would. This alone increases run time. The higher the amp load on a cell, the lower the capacity it can give. This is generally true with all batteries. The amount of...

    Thermoelectric cooler vs. mini fridge

    Here's one from eBay: 1.7 cu ft DC/AC Cascadia Truck Refrigerator RV Fridge Cabin Van MiniBar Cooler https://www.ebay.com/itm/203095153446 about $300 for a 12VDC/120VAC That's about the cheapest you'll get that uses a compressor, and not a huge peltier. That's something else to make sure of...

    Thermoelectric cooler vs. mini fridge

    A 12V Peltier module would be fine, for a cooler, the kind you carry. But would be horrible for powering a fridge like unit. Waaaay to inefficient. The consume a LOT of power. There's a reason why they aren't used in CPU cooling applications. On Linus Tech Tips, they had to use a separate psu...

    If a battery pack is 12V @ 90Ah and the motor draws 42 amps, how long will it run at full speed

    Not really, unless you buy some really expensive equipment. Instead of using 6 gauge wire, for example, you'd use 2 gauge. Instead of running at 12V, you'd go with 48V, or 96V (most places going over 100VDC requires special permits or is flat out illegal for DIYers and need EEs to do the work)...

    If a battery pack is 12V @ 90Ah and the motor draws 42 amps, how long will it run at full speed

    This is assuming 100% efficiency, which we know is not possible. Actual run time may be more like 80%, or 1.3-1.4hrs. And even 80% is a bit optimistic, to be honest.

    Anyone know of a 'dumb' BMS ?

    Ah yeah, that's right. I forgot those numbers were imperial tenths :P Thanks for the correction. So it's even smaller than I thought lol

    Anyone know of a 'dumb' BMS ?

    You can solder smt components with a standard iron. You just need a fine tip. Soldering the controller IC to the board is actually relatively easy as the pads are spaced apart. If you can solder header pins to a board, you should be able to solder these. You don't need "professional" tools to...

    Popping/Hissing sound coming from batteries, not charging/discharging

    I thought of that, but I'd need probes that are close to 10cm long. And I don't fancy reaching two pieces of metal down through a hole that's only 2cm wide. I think I'm just going to let these run as they are and replace them with a new batch of lead acids. I recently came across a great deal...
