I think the biggest problem with Lipos (if we ignore their volatility) is the way that some manufacturers just make up their numbers.

Now whilst I'm actually very impressed with my Gens Redline packs - there's no way they are 5300mah. After a couple of months of testing them, I think a more realistic figure would be 3000mah.

I charge them at 3a and with them at approximately 30%, I get around 2100mah into them. At a lower charge rate, perhaps I'd get 2500mah into them from storage levels.

We often focus on capacity when really what we need for spec racing is low internal resistance.

Voltage/C rating for punch.

Capacity for endurance.

Lipo cell technology is improving and C ratings are getting better, but we also know that these numbers are easy to lie about.

The page I linked to doesn't discuss Onyx, which as you know powered the current fastest RC car in the world

Often the brands hailed as the best bang for your buck option aren't available in certain regions. High performance Onyx packs are a significantly better option per £ spent if you live in the UK, as they are significantly cheaper domestically. And my understanding is that they much closer to the advertised specs than most other brands.

I'll be looking forward to trying their new HV 2s packs in 2WD buggy and the 6S HV Graphene packs in the XTR for speed runs in 2026. 🤞

Howdy Howdy, let's talk about IR. So as far as I'm aware best time to measure IR is when the pack is full. But when I measure IR with my baby skyrc charger, it basically turns into a lottery number generator. I can take a reading ten times in a row and never get the same sequence of numbers. All cells can vary wildly going from low single digits to double digits, is this normal or is my charger a pile of 💩

IR numbers can seem like that on chargers when the packs are low, but it shouldn't be random when the pack is fully charged, right?

Perhaps your charger is telling lies! 😅

That's exactly what I thought, oh well new charger soon
 
looking for a budget 6S lipo thats reliable, any thoughts on the RAPID ones or the turnigy boltx high voltage?
ZEE any good?

I had a similar problem when my Traxxas batteries balance plug connectors started to go bad. Repairing the battery by soldering on industry standard balance leads solved the issue.

You may also want to clean the connections. I use a product called Deoxit from caig labs to clean, lubricate, and protect my electrical connections. The lubricate function is very important for high ampacity QS8 connectors.
