Is it possibly balancing the cells? Is it Bluetooth so you can turn the balance on and off?

Sounds like the BMS is shutting off for high current. What is the battery voltage before the bms? Also have you checked individual cell voltage?

I think I would have someone mig welder the studs back on vs drilling and tapping them.

That's ok you'll probably never see 10amps due to line loss. Let it charge until you see 0 amps of charge or relatively close to 0 amps. At that point hopefully your close to 14.6v but after a few hours your battery will rest or float at around 13.6v. I guess as long as you are getting 100ah...

I would use the Amazon charger. It got good reviews. You can also use both chargers at once to charge faster. The two together should give you close to 30amps

Hi

I would use the charger you bought on Amazon and set it to lifepo4 and let it charge to 14.6v.. I read the Amazon listing on that charger and it says it will bulk charge to 14.6 and then float charges at 13.6v. All lifepo4 battery cells I have seen have voltages of 2.5 to 3.65v 4 of them...

I think that is happening because your shunt meter hasn't been calibrated to the correct voltage vs amp hours used. I would leave your radio on until the BMS on the battery shuts off. Then recharge battery to 14.6v and etc that as your 100% charge level.

Well the one they sent you says it's output is 14.6v, so it should fully charge your battery to 14.6v. So that is good. And after fully charging to 14.6v a lifepo4 will have a resting voltage of 13.6v. That is where you want your renogy shunt meter to read 100%. On my shunt meter I had to...

Doesn't sound like your charger is charging your battery at the right voltage. When you are charging does the amp meter go to 0 amps or is it still giving you 2 or 3 amps going in? It should charge to 14.6v and float charge at 13.6v. Once you get your battery to 14.6 volts reset your amp meter...

The transfer switch is to keep you from back feeding power out to the power company lines when power goes out. If you are send out power this could kill one of the workers trying to fix the power lines.

If you have a car Audio installer near by, have them install new ends on for you.

Since the inverter is 3000w the math would say 3000w ÷ 48v = 62.5amps. But I would imagine you have a common port BMS so charger and inverter will use the same wire. And the charger is 80amps. So the 100amp fuse will be fine.

Your battery monitor should be set to these parameters. Renogy battery monitor settings: -Capacity - 100Ah -Full - 14.6v -Zero V - 10.8v -PowerOff - 10.8v (Li Time then told me switch it to 12v just to be safe) -Alarm - 5Ah -Atten - 0.2% Is there a reason you can't leave the charger on all...

That's correct you need to get a different BMS. You need a common port BMS not a separate port BMS.
