My next battery build will be a 16.8 Ah 12S4P made with P42As. Their data spec sheet lists a standard charge current of 1C or 4.2 amps. So theoretically this pack could be charged at 16.8 amps. It also means that a 4a charger is a measly 0.25C charge rate. Anyways, as I started to look at higher amp options, I was limited quickly by the 5.5x2.1 dc barrel connector. There are some “10 amp” capable ones that look identical to the 5A rated ones online.
I just finished building two 20AH 12S5Ps. And these are tiny compared to what some people are building into rather small enclosures. I expect battery capacity to continue to grow as will the desire to charge faster.
Having said all of that. I’m thinking about getting something in the range of 8amps to use at home for quicker charging and having a smaller one for travel. Any recommendations on a connector that retains a small form factor on the enclosure side without taking up too much enclosure space. Something with a higher amp rating in the 15-30 range would be preferred.
Been looking at the GX16-2 which is 15 amp rated. However I don’t see any dust covers
Then again comes the challenge of available terminations on the charger side of things
True. Mine are, but are in completely different settings. Loopkey slot is in a 3d printed holder on the back (thx @mmaner) and chargeport requires me to open the case and unplug my lightbar (it uses the chargeport for power) to connect the charger
I saw that. There’s a two pin of that available too but I hadn’t considered doubling the 4 pin @b264 at the same time an XT60 really isn’t much bigger especially compared to a 5.5x2.1 socket. I feel better about the durability and there’s no question about the amps
I’m gonna be using this connector and receptacle (mayble smaller receptacle) for 3phase 400v 30A charging on an EV, not quite what you’re looking for but definitely more on the exotic side of charging. Its good for 36kw, and probbaly won’t be the max I can achieve
