Some background: I built my own LFP battery consisting of 16 CALB L160F100 with the JK-BD6A24S10P paired to a LuxPowerTek SNA 5k unit. It is 50 days old showing 21 cycle counts on the BMS as of 26 Oct 2023. It took the battery (51.2V, 100 Ah, 0.6 A active balance current) a full month to...

Do you know that LFPs need to be balanced every few months and not at every charge cycle? OR Are you aware that setting float voltage of your LFP battery above 3.37V/Cell is overcharging it and harming its potential lifespan and causing cell imbalance? Chances are extremely high that you don't...

How on earth, an inverter (LXP-SNA-5k) when told to maintain FLOAT voltage (53.4 V via CAN) slowly (See graphs from 3 PM onwards) increase its voltage to more than the CVL sent over CANBus ??! From Cutoff to Float mode, the only thing that changes is CCL from 0 to 50 Amps. But the inverter...

The first part of this guide can be read here. 4. Top-balancing and maintaining Balance with help of BMS Suppose you got a battery with N factory-new cells connected in series. What is the most appropriate way to top-balance this battery? The solution is what can be termed as balancing after...

I already know that BMS is supposed to be the last line of defence and I'm supposed to control charging via charger itself. I've been toying around with the idea of implementing 'convergent' balancing lately. Which basically means balancing only after charging has ended, with no current going...

What equipment I have: Luxpower SNA 5k paired with JK-BD6A24S10P BMS monitoring a 16 Cell 100Ah CALB LFP battery BMS comms is not currently possible The issue I'm currently facing: I have to put time and efforts changing charging parameters everyday for correctly charging the battery. Very...

I typed up a long ass post and saved it for later in draft. When I tried looking for it today, it was nowhere to be found. Bummer! Apparently, drafts are saved only until 24 hours. The 'save draft' button should contain a warning like this...

Just wanted to post my findings about MPPTs in this thread. Just out of curiosity, I stumbled upon this, reading more and also watched its video a year ago: https://www.instructables.com/DIY-1kW-MPPT-Solar-Charge-Controller/ I was thinking of our new house we are planning to build in the...

I recently got net metering installed and frequent power cuts is common here. My equipment: LuxPower SNA 5k paired with a 51.2V 100Ah battery. What I want is a grid dependent battery charging current limit, If the grid is available, I want the battery to charged slowly (or not at all) at the...
