Battery Upgrade

The original battery included in the GoTenna Mesh (GTM) V1.0 2017 (with RF Shield) is a 589mah 1S LiPo (Lithium Polymer).

LiPo batteries are identified by their composition, where (S) = Cells in Series and § = Cells in Parallel. In the GTM, the 1S means we have one cell in series for a 3.7V nominal (3.0V low and 4.2V high). If upgrading the battery the minimalist way, you will want to keep to a 1S (3.7V nominal) LiPo battery to ensure the charging circuit still works appropriately and you do not fry the other components on the PCB.

My first mod is to replace the on-board batt with an off-board higher capacity 1S LiPo battery using XT30 connectors to allow for an easy change-out of batteries. The batteries I’ll use will be 10,000 mAh 1S LiPo’s. These will generate 16.9 days worth of charge.

Instead of attempting a solar panel/charge controller/battery bank to charge the battery, my plan is to simply replace the battery and charge it at home.

With Respect,

How is this mod going? Seems straightforward.

Very straightforward. Put on hold because the switch broke off and I need to replace that first! Sourcing batts and a new switch and then I’ll update with pics.
