Hello to you all.
Can I ask for some knowledge and expertise please.
I have a Gametraks Electronic Caller that is powered by 3 of the Lithium-Ion 3.7 volt battery packs ("which seems a bloody dull idea to me and also not easy to source the 3.7 volt small battery packs of the right size and mAps. ?")
The 2 batteries driving the amp and speakers are both the same sized 3.7v batteries and are both rated at 3000mAp each and are 80mil long X 35mil wide X 12.5mil thick.
With the hand held remote battery being very similar to a Nokia mobile phone 3.7v battery rated at 1800mAp and 50mil long X 35mil wide X 10mil thick.
Would anyone have a think and possibly point out options to rethink how to power this E-Caller in a more user friendly manner.
The only 2 choices that I can see is either parallel wired 18650's battery packs with PCM's
or
Small Lead Acid Sealed Batteries with a 12 volt to 3.7 volt regulator to limit the power output to the caller (think they might be called "Buck ??????")
The Gametraks.com E-Caller website is still running but I understand from my searching that they went quite and stopped trading several years ago.
I would want to choose the best option because although these callers are out of production now they were $500.00 plus callers 8 years ago
The small 3.7 volt battery design might be O/K when new, but 3.7 volt batteries do not last and are dull to replace when the company no longer exists ??
Makers battery pack number of the pair of batteries only states >>>
BW-123582, 3.7v 3000mAh (made in China) "probably charge and discharge protected ?"
And the third single remote battery seems to be charge & discharge protected and is marked >>>
PR-103450
H80729402
1800mAh
I would value any ideas about the best options
Hope I not imposing ?
Thanks
Phil
