Thanks Pajda, the 35E datasheet agrees with you entirely about charge current, it says 1020mA (0.3C) for best cycle life which is what I'll be doing. I have plenty of capacity overhead for my application, so for me I want to prolong the life of the pack as long as possible. I just read this...

Is there a single display that I can mount remotely from the battery that would show a 'fuel gauge' and battery temperature readout?

would charging just to 4.1v be better for lifespan than charging set to 4.2v? I charge at 1.02A because datasheet says that's best for lifespan thanks for the amazing quality of responses

For LiIon I can adjust it as high as 4.15v but no higher. I wonder could there be any downside to me setting it to LiPo to get the 4.2v charge voltage I need?

Just need to build a decent enclosure for it now

Hi, the datasheet for the 35e says charge voltage is 4.2v, but setting up my isdt t8 charger, it seems to say 4.1v for LiIon and 4.2v for LiPo. I thought the 35e was LiIon, even the datasheet says lithium ion, so why doesn't my charger not let me set LiIon to 4.2v? Is the 35e actually a Lipo...

Thanks very much for the advice. Yes, I got the nickel and plastic honeycomb cell parts from the polish kart company, very happy with their products. I'll solder on some thick gauge wire along the final negative and positive strips as you suggest - but other than that, should I be putting on...

That psu is just to feed the isdt t8 dc to dc "proper" charger

Before I spot weld this bad boy up, I'd be hugely grateful for any advice, should you notice something 'wrong' 91x samsung 35e in 7s13p configuration, so a 24v system which will have a continuous load of around 13A, and a theoretical peak of 74a for 10 seconds which will probably never/rarely...

Thanks so much to all for the huge quality in replies, extremely informative

I'm upgrading this mobility scooter to lithium, and thought it would be a good idea to keep stock connectors here in case it needs to be put back to stock (I will probably upgrade the awg of the wire from this connector back to the controller board) So, anyone know what this connector is...

Thanks for the advice so far, It's helped a lot. I liked the cycle satiator a lot, but being in the UK, the 24v version would cost around £350 after import duty, customs handling fees etc. ISDT T8 at £85 seems a good dc-dc charger. https://www.isdt.co/t8.html?lang=en I found a fantastic deal...

I'm unsure how many amps I need. given that I want to preserve the life of the cells - in a 7s13p pack, would I charge at 7x times the amps needed to charge a single cell, or 13x the amps needed to charge a single cell? My brain tells me it's the parallel that increases the amps, but I want to...

I looked at the satiator, but that didn't appear to do 12v, rather 24 volt and above. I don't need concurrent use for sure. Thanks again
