Wow, 2,600 LiIon Pack?

Chris Smart All Messages By This Member #19144 开云体育 Has anyone tried one of these? What charger would go with this? ? Admittedly I don’t know much about NiMH versus LiIon, other than NiMH apparently last for more charge/discharge cycles, but LiIon work better in the extreme cold. ?
Nick Rylatt All Messages By This Member #19145 开云体育 You have to take capacity ratings for Chinese-made batteries with a grain of salt.? When rated using standard test methods, the capacity is often lower. You need a charger specific to the lithium ion chemistry. A few years ago, I bought a lithium ion battery and wall wart charger combo from eBay. 73, Nick, AA3T On 10/19/2021 10:10 AM, Chris Smart wrote: Has anyone tried one of these?

Chris Smart All Messages By This Member #19146 开云体育 Thanks Nick. ? I found a 2,500 mAH NIMH pack elsewhere, so I might try that instead. ? ? ? ? toggle quoted message Show quoted text From: [email protected] <[email protected]> On Behalf Of Nick Rylatt Sent: October 19, 2021 11:42 AM To: [email protected] Subject: Re: [Yaesu-FT-60] Wow, 2,600 LiIon Pack? ?

Evan Platt All Messages By This Member #19147 I personally would prefer the LiIon vs NiMh, but yeah as mentioned, check the actual capacity. If the capacities are close, I'd take the LiIon over NiMh. toggle quoted message Show quoted text On Tue, Oct 19, 2021 at 9:06 AM Chris Smart <ve3rwj@...> wrote: Thanks Nick.

Clint Bradford All Messages By This Member #19148 Quality MiMH are 2700mAH ... 750-1000 discharge-charge cycles if intelligent charger is used. -- Clint Bradford K6LCS http//www.work-sat.com

Gus (W9SSN) All Messages By This Member #19164 Interesting find. About a year ago, I printed a free design off of Thingverse.com for an 18650 cell battery pack (the same one that has been mentioned here). It works pretty well and provides a ton more battery capacity than the standard nimh batteries, which are terrible. I probably should be using a bms, but I don't and have yet to have a problem. The nice thing is that I can carry a couple extra cells in a back pack and swap them out if needed, although I do not recall a time when I ever needed extra batteries. I harvested a ton of 18650 cells from old laptop and e-bike batteries that people were just going to put in a landfill, so I have a near limitless supply of power for my FT-60 now!
Prasad All Messages By This Member #19165 I would go for this if only the construction allowed replacing the two cells which appear to be 18650. Sadly it does not appear to be like that. The only reason is a properly molded case looks better than a 3D-printed one. Of course, I would still need a charger.? de AB3EH??
Prasad All Messages By This Member #19166 Gus I have worked on your design. Now waiting for the end contacts to arrive. The main case is ready and fits.? de AB3EH
