Thank you to @FilterGuy for the resource on nickel plating. Worked great for me after some learning that had nothing to do with the resource information. Beautiful colour with nickel welding rods: Fake nickel strips because only plated: I first bought nickel strips paying very careful...

Show and tell for Fluke meters. Took some interesting pics while measuring freezer compressor inrush and running currents. Have measured AC inrush many times but first time I measured DC inrush and surprised how low (power) compared to AC inrush. I would like some help understanding why inrush...

Hello, My questions are on minimising battery stress on old cells. Not worried about giving up capacity by limiting voltage and amps. Question 1: 0.5C discharge and 0.2C charge OK? Question 2: Operate between 3.00v and 3.40v per cell and NOT balance or operate between 3.00v and 3.60v and BMS...

Solar panels on a ping pong table frame, not playing ping pong on solar panels. Question is on PV panel grounding / lightning protection requirements if I have temporary solar panels not fixed to the house structure but connecting to an SCC and an inverter inside the house. No code in Thailand...

Hello, i bought scotchbrite 7447 and measured battery IR before and after cleaning by hand but there was no change. I then put the scotchbrite on an orbital sander and gave the terminals a three second buzz while pressing firmly. Still no change. I am measuring with a YR1035+ so is it just that...

I have four x JBD SP04S020 from HankzorBmS store and want to add the external switch to them like Overkill. The switch position on the board is marked in Chinese but google translate app confirms this is for the switch. The overkill manual shows red pos on left and black neg on right. Safe...

My Hankzor 80A JBD BMS have 2 x 10 AWG wires. There is a hole for a third wire to solder. I am 99.9% sure I will destroy those BMS if I solder (poor skill) so I can either leave them as is or bolt a third wire to them. Pics show how one looks with an 8 AWG wire added. I couldn't get a good crimp...

Hello from Bangkok, This is my first post but have been enjoying reading the forum and learning lots for many months now. I have two 12v 100aH gel batteries that have been on standby charge for about 3 years with occassional use. I want to double my capacity to 400aH and cannot decide...

Hello forum, I am going to have 4 x 12v 100aH gel batteries in parallel single bank with 2 x Xantrex TC2 40a charging them for standby use for brown outs / short black outs and Epever 4215BN for cyclic use in event of major power outage. I have two x 380w 72 cell panels on a ping pong table...
