In a friends cabin, we replaced a 20 A (Epever) charge controller with a 40 A SRNE SCC (SR-ML2440), and doubling the installed PV to 520 Wp. The batteries are (old) 6 V, 235 Ah FLA in 2S3P configuration. The new SCC is configured for FLA, but the voltages frequently reach and even go beyond 15...

I am putting together a kit for a really cold climate (northern Quebec, down to -40 C and below). I am planning to build a box of 4 inches of foam board, and use heated SOK 100 Ah batteries, 2 in series for 24V. The manual of these batteries states that they can only be put in parallel, which...

I am running test with a self-heating battery, and I noticed a certain behaviour when charging at low temperatures, and I am wondering if that could cause a problem down the road. The battery is at -11°C (below freezing), and when I apply a 1 A charge current, the following happens in the...

I ordered 2 SOK 12 V 100 Ah heated from SOKs Canadian site. I noticed that neither one of the two BMSes showed up in their app, although they are supposed to have Bluetooth. I then measured the voltage, and in both cases it is at 10.9ish volts. This means that the battery is below 10 % SOC, and...

Does anyone know what the differences are between high quality fuses (like ANL or MEGA fuses from Blue Sea Systems) that sell for over 40 CA$ a pop, and low cost ANL fuses (from Amazon, 17 CA$ for 6)? I tend not to save money on this end, and I totally get why cheap circuit breakers are a no-go...
