Charger Advice Needed Please - 13 * 18650 in parallel.

Batteries and Chargers Chargers

Ive put together a battery pack of 13 x 18650’s in parallel to power my Skyray King during long bike rides, but I need a way of charging them without removing them from the pack. So basically, I will have one power charging port that I need to top them off no higher than 4.20V. It would be nice if I could adjust the final termination voltage a bit lower (to say 4.16V). I dont mind a 10 hour charge cycle, but it looks like I will need at least 10A on a single channel to do the job. 15A would probably be even better.

Does anyone have any thoughts or recommendations for a hobby charger/power supply?

Thanks

How about 20 amps charge current?

5A of iMax B6 would overcharge your cells, as termination current would be 500mA for 13 cells, which is 38mA/cell - WAY lower than recommended charging termination current for most cells (generally 50mA-100mA).
I’d recommend iCharger 106B+ at 10A for that purpose - at 1A termination current, that’d be 77mA/cell - high enough not to cause any overcharging, and the best thing is, you can adjust charging termination voltage from 4.1 to 4.3V, so 4.16V that you want is possible!

He is simply going off the datasheet. :)

Thanks for the replies.

So if I understand correctly, the 5A nor the iMax B6 will not sense termination properly for 13 X 18650’s in parallel but the iCharger 106B will?

I really like the B6AC because of the onboard AC charging option (one less thing to buy and lug around with a dedicated power supply). Is there a way to make it sense termination properly for the 13 x 18650 battery pack?

Any other cost effective ideas?
