DPL 8x2: any news on unbalanced charge limit?


Hello
Was there ever any news or firmware update regarding the 2A current limit when charging "no balance connector" LiIon packs?

Thanks !

Because of the inherent liability risk with unbalanced LiXX charging, the max 2S and 2A limits on unbalanced LiXX charges still exists in the PL firmware.

However we are currently designing a whole set of software changes to formally support LiXX Smart Battery (with internal balancers) which may address your needs. It will most likely *require* the use of the BumpTags and either the Bump Controller or any of the new (available soon) PowerLab Touch series of chargers.

ITC - are you needing to charge a Smart Battery ? how big ? how many amps ??

ITC & EVERYONE - please provide us with all of your use-cases for unbalanced LiXX charging so we can use that input to shape the design of the feature.

Hi,
In this particular instance, the battery is a Jeti Li-Ion 2s 2600mAH, part number RB2600. 2 each per airplane for Receiver/Servo power. It is not a smart battery.

It has NO internal balancer electronics, just matched cells by the manufacturer (Jeti) at time of assembly. There is no balance lead.

The information is here:

They are capable of being (safely) charged at more than 2A, which is why I asked the question.

The only other batteries I own which do not have balance leads are from Duraflite (I guess they could be considered Smart) They are their Sentinel series of batteries, which have internal balance electronics and would not be charged with my Powerlabs.

My Windows/Android 9.7" dual boot tablet is en route, so I will be buying a BumpController for my DLP8x2 charging case, so if I had to use a BumpTag, that would not be a problem for me to be able to get more than 2A unbalanced charge for these batteries.

As always, thank you for your assistance and support.
