The law of averages my friend. And in this industry sooner or later someone is going to get a bad device. @MasteroftheVape, I hope you get your Relo fix soon.

I just got this info from a vendor who was going to be receiving his first batch stock soon.

"They say there's problems with some of the chips and evolv is having a hard time supplying them! They're limiting orders and even their distributors don't know exactly when and how many they'll get."

Also want to share some captured youtube images from a Russian reviewer. Showing the dismantled Relo. Hope it helps....enjoy.




After building a couple of DNA200's this work is cheap and not even at the wire recommended size from Evolv. Given these can push 200 watts I'd want much larger wires used if this is supposed to last any duration.

They also should have kept the balance wires all the same length to help with getting a good charge.

Guys, about the suggestion to "married" the cells...

(Frankly i have almost no knowledge of the advantages of this suggestion, but i am sure it is for a good cause, at least to make sure that our device would got the best amperage deliveries of each "pairs" or in this case "triplets")

But how do you charge this "triplet" and keep their "marital" status okay?

I don't have any I4 or D4 in my possession, but from what i read these chargers can only deliver "uniform" voltage to a "paired-slot" one at a time during charging.

The source: Test/Review of Charger NiteCore Intellicharger i4 2014 | BudgetLightForum.com

And this is what i understand from that site (please pardon my grammar, and also my lack of battery knowledge if i fail to understand the technical issues)

ie:
If you charge 2 pair of cells at the same time, these charger will deliver certain amount of amperage to one paired-slot (slot 1 and 2 for example) for several seconds and then deliver to another paired-slot (slot 3 and 4 for example) for another several seconds. Thus one paired-slot at a time

Yes, each paired-slot will reach its maximum capacity like in the same time (give or take)

But wait, this is what concern me the most: that amperage delivered to certain paired-slot is divided by two if there are two cells occupy each slot in a paired-slot.

ie:
Cell A B and C are your "triplet", you charge your triplet in a I4 or D4 in this configuration
Slot 1 cell A
Slot 2 cell B
Slot 3 cell C
Slot 4 empty
Slot 1 and 2 are the paired-slot, another paired-slot are 3 and 4.
the charger will deliver 500mah to slot 1 and 2 (paired-slot) for certain seconds, and then deliver 1000mah to slot 3 for certain seconds (since another slot in this paired-slot is not occupied)

In the end you would only get cell A and B "married" while leave the cell C alone

Am i getting this right?
So, i was wondering if charging your triplet powered device using onboard usb port would be the best.

--edit
(And there might be possibility that the paired-slot in I4 and D4 actually slot 1-3 and 2-4). OK this is mind boggling for me :) but that is what i got after re-read the source.
--re-edit
amperage deliveries during charging is simplified, the source numbers are way to complicated for me.

I'm not sure what gauge the power wires are but they look to be at least the minimum 2 gauge. And the balance connector wires although tiny don't need to be very big.

I am not an expert on electricity or batteries. But marrying batteries together means to me: taking new batteries and dedicating them to only be used together within one particular device. This applies to dual battery devices as well as triple battery devices, such as the Reuleaux. That way the 'married' batteries age together, none getting to far ahead or behind in its ability to charge, discharge and recharge. For all intents and purposes they remain relatively equivalent to each other. In this way they work together.

Therefore, matching each other within the 'marriage' you are less likely to have one of the batteries so out of balance with it's mate(s) that it becomes over taxed and vents.

I do not see this as a thing which needs to be nickpicked down to the most minute degree. Rather, just take two or three new batteries use them together in the same device, charge them together at the same time and put them back into the same device. Dedicate them to the one device and this one device only and you should be just fine.

    I had high hopes for this mod.
    Wonder why would they skimp on the wire gauge?

    They really didn't. The balance wires should be even but the gauge can be minimal size. The battery wires only need to be 18/20 gauge. Mine works perfectly and all cells stay balanced.
