Lithium Ion Batteries

A discussion on LED torches turned in to a discussion on Lithium Ion Batteries.
I think it worthy of its own thread,
Lithium Ion batteries have been around for a number of years, my first personal encounter being around 6 years ago in a laptop.
This battery technology (in laptops) superseded NiCd batteries which had a number of issues and are almost extinct now.
My understanding is that recent issues of Lithium Ion is not their storage but their rapid charging.
Most recent dramas seem to be related to hoverboards and power packs both of which are being rapid charged.
So the problem as I see it is not the batteries but the charging techniques being used.
I think they [Lithiun Ion batteries] are going to be around for some time but their chargers are going to be revised.

You're right that charging is where most problems occur but even the design can be problematic. I try to avoid buying cheap Li batteries as many of the problems go back to design, assembly and QA.

An acquaintance used to run a testing lab and one of the projects they tested were some Li battery packs for Boeing (think 787). Rick told me the testing went well without any problems so they packed the batteries back up and palleted them ready for shipment to the vendor after the weekend. The battery packs caught fire over the weekend sitting on the shipping dock unmolested.

By the same token, today's batteries are only dangerous because of their high energy density compared to older styles.

I've been looking at a way to boost my truck during winter, and stumbled upon Li-Ion packs around 11kmAh that claim to be able to give out 400amps and able to start a V8 engines. Of course there are chinese products on alibaba that cost half to one third of the price, while having a capacity of 1GmAh (lol jk, was more around 50k mAh).

Any truth to that? Anyone here tested them? They look so small and light, i'd be able to take it with me when i go camping with the Strom.

It's not the charging techniques causing the "hoverboard" battery fires. But simply the low quality batteries themselves, and the very nature of being knocked about a bit. Buy a good quality one and you are set for camping.

I never go riding without our Microstart...

http://themicrostart.com

.soooo useful and yes a battery the size of a pack of twinkies will start your bike or car. We have the XP-3






On one bike I'm not bothering to wire in a USB power out as I just tuck the Microstart in the tank bag and I'm good for all day and then some even on full bright and GPS.

I use a Shorai in the KLR cuz they are good in the tropics and weigh nada.

Like Macdoc I have one of the Antigravity units. The rest are basically cheap knock-offs.

I have a Microstart XP5. I is mainly for bike use and is in my top case all the time. I don't have a V8 to worry about starting, but this unit is supposed to start a small V6 with no issue.

I wouldn't want a battery to catch on fire -

1. under the seat of the bike
2. in the top box
3. in a pannier
4, in the tank bag
5. in my pocket

I think I am running out of places to store it.

Wait, I have it

1. Give it to your pillion to carry
You can always bump them off the back providing you haven't got a top box

I have had 2 of the cheap Chinese copies overheat the battery when on charge, the battery got hot, expanded and forced open the case (I think I posted photos on this site ?)

The first I used to start a car with a very very dead battery and the second just went flat while sitting under the seat of my bike for 5 months, in both cases I think the charger did not shutdown when the batteries were full.

When on charge don't turn your back they are dangerous little things.
