Wow guys, this JST NSH https://www.jst-mfg.com/product/pdf/eng/eNSH.pdf is a nightmare. the whole 1.0mm pitch x6 is smaller than my pinkie and I would need special crimp tool to assemble a male wired plug. This is a serious issue against JK BMS cos any loss of connector cables means your BMS...

Can anyone identify the connectors used on the new black JK BMS, for the No3 LCD display 6pin 1mm pitch and carries a thin spade locator - NOT JST AFAIK. Mini JST SH 1.0mm Pitch Wire Connector SH 1mm.

The worst nightmare is fire on board afloat, and electrical connections are a serious culprit (especially if one is a bit slapdash about all that stuff - come on own up). PVC sheathed cable gets hard to handle as it ages (with heat) especially around machinery. Silicone cable is a much better...

Good User info JR. As you say a lot depends on the environment - and warm marine is the worst. Maybe a take away here (apart from your preferred grease) is that copper - elec connections need to be cataloged and inspected periodically YMMV on nautical locations. But then so much else afloat...

I had one of these, beast to start (typical poor spark from magneto). Lots of thump G3L and one of these BSA M21 600cc sv - easy starter (geared for sidecar outfits), ride around town in 3rd gear, cr 5.5:1 meant I could run it on paraffine oil - light heating oil) which was 1/5th cost of...

Silicone grease is what it is - insulator. WTF do we call it dielectric grease !!!!!!!!!! It sounds to me like some poisonous marketing mongrels decided to take a $ product and repackage it for $$$. Urban myth now is that its supposed to have conductive properties - like "copper grease" used...

do you mean a 250? thought they only made a 350 or 500 - big thumper and an ankle breaker to kick over

Yep JR that sums it up very well (dump the MC4s) I like the idea of sharing load current, split it into say 50% paths, dont go loading connectors to max. (eg 2 x 20A paths are more benign than 1 x 40A path - cos heat = I^2*R and the devil is in your contact resistance. I also like the idea of...

Right on bro - there is no doubt there are some very sound guidelines laid down in the site (even as a promo). Sadly Cheap Charlie has infected the whole domain of terminations from thin wall knock offs, crimp tools/anvils dont work giving very unreliable joints, poor quality heat shrink, and...

Btw @wattmatters great test work good science here. FWIW IIRR AGMs do not like large charging currents dumped into them > 0.1 C for 100 Ah - its a chemistry thing, also volts abov 14.4V gassing? So putting AGM//Lifepo you need to regulate charging to limit inflow to the AGM Also AGMs need...

Indeed I found these eventually. WOW they are an expensive solution as you need the $$$$ kit to crimp properly and the ferrules are $$$$, all special. I appreciate that a lot of engineering has gone into what seems at fist like a simple system.

Guys these are the standard "Lucas" pattern push fit connectors widely used in the auto industry for decades. However beware Chep Charlie, he makes these out of thinner metal so they dont maintain the spring force between blade and female socket.. Check your self to see the difference. In...

yes you are quite right. These arm chair speculators dont know Jack Schwepps. 14.4v is good for a Lifpo4 - 4s you dont lose much Ah<5% and its less stress on the cells = longer cycle life. You can take Lifepo down to 2.5V/cell = 10 V for 4S but thats a little low for AGM (only likes >50%DOD...

BougeRV supplier of fridges, solar panels etc for recreational vehicles MC4 style connectors - btw the staubli original was not designed for multiple matings as you say YMMV and these are only rated for 30Adc thnx

If only it were that simple Buddy, I wouldnt have made a heretical post. For a start Cheap Charlie floods market with counterfeit items that are thinner and inadequate to maintain grip force let alone perform cold welding, also many of the ordinary crimp pliers have poor quality anvils and...
