Yeah, I don’t understand why that is. I’m using a 75 amp connector designed to work with 10 gauge wire. 14 gauge diameter * 2 should be the equivalent of 8 gauge. Yet they were loose in the 10 gauge fitting the first time I tried it. The math doesn’t seem to work out.

Hello, I recently bought a Mean Well HLG-600H-15A for use as a lifepo4 battery charger. I was dismayed when it arrived because it has two 14 gauge, 18 amp DC outputs, rather than one 36 amp output. According to Mean Well tech support, these wires both come from the same source internally, but I...

I have a SK3 192kv from a previous project: https://hobbyking.com/en_us/turnigy-aerodrive-sk3-6374-192kv-brushless-outrunner-motor.html Can this motor be driven at 14S voltages? I see it is only spec'd for 12S, but I know people sometimes overvolt things so I thought I'd ask. If not, can...

I did not see that form at the bottom of the page or know about the adjuster. Thank you. That's a really good option. This looks like the exact same charger my Organic Transit ELF shipped with BTW. ;)

Read the OP. This wouldn't work for me.

Since the voltage isn't adjustable within the 12v range, that charger most likely charges at 14.4v. I could use something like that if I watched the battery like a hawk the entire time and disconnected it when it was close to charged, but I'm hoping for something I can forget about without...

It's attached to an inverter and a solar charge controller. I'm mostly interested in charging from a Yamaha 2000is generator, but sometimes grid power too. I don't follow on the size question. I listed the battery specs in the op. I like the adjustable power supply idea. Might go that route.

Hello, I've got a largish 12v 100ah GBS LifePO4 battery. Not really an ebike battery (more of a solar battery), but I thought I would ask here since you guys probably use AC chargers a lot. I currently charge at 13.6v bulk, 13.5v absorb, and 13.4v float. I'm bottom balanced, so I really don't...

The problem I have is this charge controller. It doesn't really have a LifePO4 charging profile. It only allows you to adjust the Bulk MPPT, Absorb, and Float voltages. There's no way to turn off float at a certain voltage in software. So I have to use the AUX2 12V logic input to tell the charge...

For a 1200wh battery, I'd want 1.5C discharge and 1C charge. The 100ah GBS prismatic battery I keep coming back to meets those criteria.

See the youtube link above.

My charge controller wants to know when to stop charging via a signal from the BMS. That's the only reason I'm not keen on internal BMS without any outputs.

Do people still use prismatic cells in projects? I guess that's what I'm asking. I'm not trying to make a super car. I just want something fairly reliable and light weight. I'd hate to spend 1.2k just for someone to tell me, "dude, no one uses those anymore because of X" and then feel like a...

I could get a gbs system with a bms that has outputs for about the same price. Maybe a little less. Is there an advantage to using a round cell system vs prismatic?
