The worst that will happen is you drop a pack too low and the charger wont recognize it, then you would need to "jump" the pack enough for the charger to play nice. these cells are rated for over discharge and in order to be certified must past the test with "No Fire, No Explosion" This isn't...

PTB have no internal circuitry to prevent them from being over discharged. Its always up to the tool to depict when the battery is too low for use. In a real world situation, so long as your packs aren't wildly off and you aren't burning your packs down to zero, disabling the imbalance feature...

There is a voltage divider circuit between the 2 packs which brings down the voltage of one pack down to something that the ADC can actually read. In the firmware theres a setting to adjust what this resistance value actually is (no one should mess with this) The VESC now "Knows" what the...

Ive had several guys talk to me about this and it honestly is the best possible option for running the PTB route. For those not familiar the "FlexVolt" system can be ran either in a 5s3p yielding 12Ah @ 18v or a 15s1p yielding 4Ah @ 54v. The energy capacity is the same but it allows for a...

The user replaceable cell model is something thats used to easily get around FAA regs on flying with batteries. While they still need to be UN38.3 certified to fly with cells in them, if all the cells are removed before transport, then no cert is required. Fathom made these for a bit but they...

We offer replacement packs aswell at ExplorerTechnologyLLC.com

shoot me an email Jona@ExplorerTechnologyLLC.com

Valid point. Haven’t looked into it and don’t really want to find out that hard way. Probably cheaper than 4 rEvos to Libya. 😝

similar to the Dacor SV900. The problem with running a lithium pack in them is there is almost no voltage drop. then you are overheating the hell out of it and will destroy it in a pretty fast fashion. That SV900 with a 4S Liion was out clocking some Cuda's when I did that but It had maybe 10...

Correct. These are limited to 12s. I actually have a couple that we use for our test bench. Its tied into a larger battery bank so we can use the regenerative discharging and cycle the energy back and forth instead of using our higher wattage discharger that dumps it as heat. Ive been looking...

I have moved about 3 cuda 400s since this post went up. Shoot me a note and Ill add you to the callback list. Still have a few sierras here though

this is another reason to have mavs that are designed to fail closed ie have the upstream side opposing the direction you push the mav so that in the instance you lose the button or have the spring fail, the IP will always keep the button closed instead of forcing it to stay open.

Ive ran my classic in several different configs over the years, valves up, valves down, FMCL, you name it Ive probably tried it. Sounds like you are looking for valves up as a mobility issue as opposed to a trim issue (I ran my valves up to get the head down.) What you can do is run a stand if...

Hi there. We have the 3 blade versions on the site but not the 4 blades. Those are a custom order. If you are interested please shoot us an email. Thanks

It all burns back to the UN38.3 and IMHO there isnt a large enough market to warrant doing another significant revision to the warp core for quite a few more years, We have reached the limits on what 18650s and 21700s can provide in terms of capacity. More jumpers = more connections more...

Wow bunch of notes to touch up on here. The Cuda X is going to be more efficient simply due to stator design. The motor is a massive pancake. Tahoe Benchmark... Yeah its been on my list for quite a while but I have too many projects on my plate to deal with it anytime in the foreseeable...

What, you dont feel like making another one?

I made note of it a few weeks ago to Thornton and he said he would look into it. In other news the new tigersharks should be available soon from Juergensen Marine which is a substantial improvement.

I have a sierra kicking around and a cuda 400 if still interested. in USA so shipping may be pricey.

Im usually never on here so I may be late to the party. I have a couple castle ESCs kicking around Im willing to offload which would be much cheaper than a smart-dpv option. But as ZJ mentioned, we do offer a super sierra kit which like kicks ass, I love the sierra platform.
